Podcast appearances and mentions of jeff alright

Show Notes Jeff: Welcome back to EMplify, the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum and I’m back with Nachi Gupta. Nachi: For our regular listeners, you probably noticed a lapse in recent episodes as we pulled away from our usual monthly releases. Jeff: With both of us having increasing demands on our time -- myself with business school and the busiest 21 month old in the world and Nachi with yet another entrepreneurial endeavor on the horizon -- we decided that it would be best to pass the podcast on to another host, so EMplify can continue to create and deliver the high quality materials that you deserve. Nachi: We have obviously really enjoyed creating this podcast and working closely with EB Medicine to produce it. We are deeply appreciative of you, our listeners, and your wonderful feedback and comments over the years. Without you, there would be no point in us working so hard on this. Jeff: And keep the feedback coming as we hand the reins to Dr. Sam Ashoo as the new host of EMplify. Dr. Ashoo is an Emergency Physician based out of Tallahassee Florida with a keen interest in informatics who has been featured on several other podcasts you may have heard. We can’t think of a better person to take over for EMplify. I’m sure you’ll really like him and the content he produces. Well, with that, let’s get started on our final scheduled episode of EMplify! Nachi: As we are just about to see one of the busiest travel days of the year, that would be the Wednesday before Thanksgiving, we thought there would be no better time to discuss the September 2019 issue of EMP: Assisting With Air Travel Medical Emergencies: Responsibilities and Pitfalls. Jeff: This was a fantastic issue, thanks to the hard work by Drs. DeLaney and Greene, both of the University of Alabama Birmingham School of Medicine. Thanks as well to the peer editors, Dr. Knight, and Dr. Hill of the University of Cincinnati. Nachi: And I think you have a bit of a disclosure for this month... Show More v Jeff: Well, this is a first! Finally at the point in my career where I can announce a disclosure, though it’s more of a potential conflict of interest than an actual disclosure, but certainly still worth noting. I currently spend some of my time working for STAT-MD - which is an airline consultation service run by the Center for Emergency Medicine and UPMC. Though I’m certainly a junior member of the team, in some sense, I’ve responded nearly 500 inflight emergencies over the last two years. Nachi: And this definitely places you are in a particularly nice position to share some information with our listeners this month, and I’ll have some questions scattered throughout the episode for you too. Jeff: Sounds great, so let’s dive in, starting with what I think is the most important point - qualified, active, licensed, and sober providers should volunteer to assist in the event of a medical emergency rather than decline out of fear of medicolegal concerns. Nachi: I couldn’t agree more, so let me reiterate, please trust the evidence. And volunteer to help should you hear the call. We’ll get to this in a bit but there is little medicolegal concern and you owe it to the sick passenger to help. Jeff: So what are the chances you are called - well, they are not particularly high, but certainly not negligible either. In 2019, of the 4 billion passengers expected to fly, there will be an estimated 60,000 medical emergencies. That means there will be about 1 emergency per every 604 flights. Nachi: So, I fly about 4 times a month for work. At 4 times per month, over the next 12 years I can expect about one medical emergency. Already excited! Let’s start with some physiology. Cabin pressurization varies, but is typically equivalent to an altitude of 8000 feet. Jeff: And this has a huge effect, in one study of healthy volunteers, this change in pressure resulted in a 4-10 point decrease in oxygen saturation and a 35 point drop in arterial oxygen partial pressure from 95 mm Hg to 60. Nachi: In another study of healthy volunteers on a long haul flight, this change caused 7% of passengers to report symptoms consistent with acute altitude illness. Jeff: Due to the principles of Boyle’s law, decreased cabin pressure also causes expansion of gases within anatomical spaces in the body such as the eye, GI tract, sinuses, middle ear, etc. This expansion can potentially threaten surrounding structures. Nachi: So there must be guidelines for those recent post-op for flying - right? Jeff: There certainly are, but I don’t think we need to get into the weeds on this one since nobody listening will likely be doing pre-flight screenings. I think one thing to remember here, is that though cabins are pressurized to several thousand feet, they CAN be pressurized even further if necessary. The airlines don’t do this because it takes a tremendous quantity of fuel to do so, but if pressurization will defer a diversion, this option may peak their interest. Though an anecdote, the only time I’ve ever suggested it is on a flight from someone recent post-op eye surgery who went blind midflight. We pressurized the cabin from 8000 to 4000 and then finally to sea level and his vision returned. Pretty cool stuff. But getting back to the text, next we have air quality. Only 50% of inflight air is recirculated, all of the flow is compartmentalized between sections of rows, and all the air is run through a HEPA filter. The authors note that the air is actually comparable to that of an operating room. Nachi: Then why are people always getting sick after flying…? Jeff: Well it’s hard to prove, but experts believe that most post flight respiratory illnesses are likely caused by exposure to fomites on high-risk surfaces of airplanes and in airports - like the trays on the seat back. Nachi: Interesting. Jeff: It’s also worth noting that the air is quite dry, though this is unlikely to produce any clinically significant events. Most of the dehydration that occurs is more likely due to inadequate water intake and excess caffeine and alcohol consumption depending on the time of day. Nachi: Don’t judge. Even though it may be 8 am, some of our night shift locums friends may prefer an airport cocktail after a long week away. Jeff: Oh I’m definitely not judging, facts only over here. Anyway, let’s move on to a little epidemiology. Nachi: Syncope and cardiac events account for a large proportion of in-flight emergencies, with cardiac events accounting for the largest percentage of diversions. Jeff: Gi, endocrine and respiratory emergencies follow syncope and cardiac events, with specific percentages varying based on which study you look at. Nachi: Thankfully obstetric emergencies are relatively rare, accounting for less than 0.1% of all emergencies. Jeff: Trauma and substance abuse related complaints have also been reported, but represent only a small percentage of inflight emergencies. Nachi: I think that covers the main pathologies you may encounter. Next we should touch upon the actual responders. Physicians reportedly respond 44% of the time, followed by nurses at 20% and EMS providers at about 4%. Interestingly, despite physicians being there only 44% of the time, they were involved in the care for over 70% of diversions. Jeff: It might seem crazy, but that’s definitely my experience. Many physicians, especially non-ED physicians are not familiar with caring for the acutely ill. Additionally, most physicians are very uncomfortable actually witnessing someone syncopize and then immediately checking vitals and finding the passenger to be bradycardic and hypotensive as is the case with many patients immediately after a vasovagal syncopal episode. I cannot tell you how many times we get called by pilots considering diversion based on a physician’s request only to have the symptoms completely resolve in just 10 minutes. Be patient, this is a common in flight pathology. Nachi: Your experience has not failed you - data from your own group showed that 31% of cases resolved before arrival. Even in cases where EMS was requested, patients were only transported 37% of the time and of those, only 8% were actually admitted for further work up. Death is also a very rare phenomenon, occurring in only 0.3% of cases. Jeff: Alright, so let’s move onto the actual logistics of responding. Each airline has its own protocols and policies with respect to medical responders - some will require credentials, others may not. In some instances, you may be the first responder, in others, the flight crew may have already been in contact with their ground based medical control. Nachi: In terms of supplies, the FAA requires an emergency medical kit and an AED on all commercial flights. These kits cannot be opened without direction from a medical professional on the ground or on board. Jeff: And while airlines may add additional drugs at their discretion, the FAA mandates certain supplies. You can remember these supplies by thinking of the 5 A’s - asthma, allergy, altered mental status, ACS, and ACLS. The 5 As should help you remember the bronchodilators, epinephrine, antihistamine, dextrose, nitroglycerine, aspirin, and lidocaine as the one antiarrhythmic available. Of course, there are also gloves, an IV start kit, and a few other basic supplies. Nachi: AEDs are also required and have been since 2001 and amazingly when a shock was delivered in flight, 40% survived to hospital discharge with a good outcome. Jeff: Just as on the ground, shockable rhythms do well with good BLS care. And lastly, airlines also have a portable oxygen tank in addition to the emergency oxygen that is stored in the event of cabin depressurization. The exact quantity varies, but portable cylinders are certainly available. Nachi: So next we have to talk about a topic that I’m sure many of you have wondered about - what are the medico-legal risks of intervening? Jeff: As with most incidents of concern over medico-legal risk, we really just shouldn’t be too concerned over the potential legal ramifications. Though we’ll get into specifics, the short answer is that you should definitely volunteer your services - there are lots of protections in place with a paucity of case reports of legal actions against medical volunteers who volunteers in flight. Nachi: Perhaps most importantly, remember that ultimately the captain is in charge and you are functioning in a strict advisory capacity. Remember that most airlines can handle most emergencies with their ground based medical control, their typical staff, and predefined protocols - you are an added bonus. Jeff: For many ED providers, functioning as a consultant will be unfamiliar. Nachi: If I’m a consultant, I’m going to demand a WBC before seeing the patient, as I’m fairly certain that’s rule number 1 in consultant school... Jeff: It’s actually rule #12, now get out of your seat and come see the patient…. But back to medicolegal issues. In the US, health care professions are protected by the good Samaritan law and the 1998 federal aviation medical assistance act. Nachi: The Good Samaritan law provides legal protection to medical providers who perform their services in response to medical emergencies outside of the hospital. The exact verbiage of the law differs from state to state, but all 50 states have some version of it in their legislation. Jeff: Similarly the aviation medical assistance act applies to “medically qualified individuals and offers broad medico-legal protection to the airlines in the event that a medical volunteer is accused of malpractice as well as to medical providers who respond to an in-flight emergency.” Nachi: More specifically, the act states that “...an individual shall not be liable for damages arising out of the acts or omissions of the individual in providing or attempting to provide assistance in the case of an in-flight medical emergency unless the individual, while rendering such assistance, is guilty of gross negligence or willful misconduct.” Jeff: That’s a bit of a mouth full to get out. But basically, you need to remember that the AMAA protects you from everything shy of gross negligence. Because of this, there have been no reports to date of a medical professional falling below that standard. Nachi: There is one caveat to all of this though: don’t forget about your own mental status - for example if you have taken any sleeping aids or had any alcoholic drinks. Though this may not preclude you completely from rendering care, do so only with extreme caution. Jeff: And I don’t think we were clear enough about this up front. Up until this point we have mostly talked about US based flights. Flights run by International airlines are a somewhat different ball game for a number of reasons. First, medication kits will vary widely. Many will carry medications similar to those mandated by the FDA, but there certainly is no international standard. Next, the availability of ground based medical consultation is similarly widely variable, with many in the middle east contracting for this service and almost no airlines in Africa offering such services. Nachi: And lastly, with respect to legal risk - the international laws also vary widely. According to French law, for example, a French physician who does not volunteer may be committing willful negligence. Similar laws exist in Germany, Australia, and Canada. However proving you were there and refused to provide care would be quite difficult. And lastly, it’s unclear how to determine which countries’ laws apply when - for example, is it the sending country’s laws, the receiving country’s laws, or the country whose airspace you are currently in? Jeff: All excellent points. Next, we are moving to my favorite topic of the article - diversion. This is a tremendously complicated topic and I think the authors handled it quite well. Remember, the decision to divert is multifactorial and you are only there to communicate your medical opinion about the passenger - leave the decision for diversion up to the flight crew. I cannot stress this enough. Getting on the radio with the pilot and ground based medical control and demanding a diversion is often very unhelpful and simply not the right approach and can really be quite costly. Nachi: All of this is so interesting. I can’t believe you do this and divert planes.... Can you go into a bit more detail about everything the pilot considers when they are deciding to divert? Jeff: So there’s quite a bit, but I can touch on some of the main considerations. First, you have to consider the medical needs of the passenger - can he or she be temporized to get to the destination? Is there a suitable airport for diversion with an accessible local hospital with the required resources? Logistically, you need to find an airport that can not only safely accommodate the plane you are on but also one in which the airline can refuel and guarantee that the passengers and crew are safe. Remember, if you are on an A380, there are only so many airports with runways long enough for a safe landing. Fun fact: planes also take off heavy - with tons of fuel that will be burned prior to landing. Say you were to take off from London, bound for the US. To turn around and land back at London Heathrow, you may have to literally dump thousands of gallons of fuel to get the plane to a safe weight for landing. Alternatively, you may have to fly in circles for some time to burn fuel off in planes that cannot dump. A heavy landing necessitates a thorough maintenance overhaul of the landing gear and can cost the airlines not only money but significant time, which is equally as valuable. Nachi: Speaking of cost - while exact costs are unknown, one airline estimates that the cost can be as high as $600,000 - we are not dealing with small numbers here... Jeff: No definitely not. That’s why it’s so frustrating when medical volunteers demand the plane divert without talking through the medical scenario with the crew and ground based control - often temporizing measures are adequate. Nachi: And we alluded to this earlier - Physicians advise diversion more frequently at 9% of the time followed by EMS providers and nurses. When the airlines are left to their own means, they divert at rates roughly half that - just 5% of the time. At half a million dollars for some diversions, and an overall very low level of morbidity and mortality, a 50% reduction amounts to massive savings for possibly no clinical difference. Jeff: I can’t stress this enough - you are a consultant, helping the captain and the ground based medical control to come to most appropriate plan of action. When your advice causes the airlines to deviate from their standard protocols, that’s where they potentially run into trouble. Nachi: There are just two controversies to discuss this month and I actually think they are extremely pertinent. The first one relates to using personal medication or medications from other passengers. Given the relative paucity of medications in most airline medical kits, it may occur to you that someone else may have a helpful medication on board. While there is no strict rule against this, it could result in an increased level of scrutiny if there is an adverse event. So consider this a last resort. Jeff: The next controversy to discuss is the issue of gifts. There is a widespread belief that accepting gifts from the airlines would void legal protections. To date, there is ample airline-based data to suggest that medical providers’ legal protections are not negated in the event that the airlines wanted to reward a medical volunteer. Additionally, there are no reported cases of providers losing legal protection for receiving compensation for their services in flight. Nachi: Interestingly, some international carriers even offer points or other bonuses for registering as a medical volunteer. While I’m hesitant to call this controversy a myth, it seems like there isn’t much evidence to support it. Jeff: Agreed, don’t expect a gift, but if you do receive one, you can keep it and enjoy it without concern for your legal protections. Nachi: Alright so that wraps up the new material for this special edition of EMplify - let’s close out with some key points and clinical pearls. Jeff: Aircraft cabins are typically pressurized to about 8000 ft, resulting in a 4-10 point drop in oxygen saturation in healthy adults as well myalgias, fatigue, and generalized discomfort on long haul flights. Nachi: Only 50% of the cabin air is recirculated. When recirculated, it is subjected to HEPA filtration, which is adequate to prevent infection by airborne pathogens but not the infectious respiratory viruses, which are spread by droplets. Jeff: Dehydration on long flights is likely due to inadequate water intake and the increased use of diuretics such as caffeine and alcohol. Nachi: There is about 1 in-flight emergency per 11,000 passengers or 1 in 604 flights. Syncope and cardiac events are most common followed by GI, respiratory, and neurologic events. Jeff: Most in-flight emergencies are minor. When EMS is requested upon arrival, roughly 1/3rd are transported and less than 10% are admitted, with mortality estimated at 0.3% of cases. Nachi: AEDs are required on all US-based flights. Jeff: Airlines have a limited supply of supplemental oxygen for use in medical emergencies in addition to that provided to the entire plane in the event the cabin becomes depressurized Nachi: All US airlines have some form of ground-based medical assistance. Ultimately any decisions are the responsibility of the pilot in command – medical volunteers function in a strictly advisory capacity. Jeff: Medical volunteers are protected by both the Good Samaritan law and the 1998 Aviation Medical Assistance Act. Nachi: The Aviation Medical Assistance Act protects medically qualified individuals, unless they are guilty of gross negligence or willful misconduct. Jeff: International laws and protections vary widely. In some European countries, for a physician to not offer their services during an in-flight emergency may constitute willful negligence. Nachi: The decision to divert is multifactorial and can cost as much as $600,000 in some circumstances. Jeff: When physicians and EMS providers respond to in-flight emergencies, diversion rates are nearly double that of when the airlines work solely with their ground based support, increasing diversion events from 5% to 9%. Nachi: It is largely a myth that accepting any gift or payment after responding to an in-flight emergency would void your legal protections; the AMAA has no language regarding compensation and to date there are no such reported cases of lost legal protection. Jeff: And that’s the end of this months episode of EMplify: Assisting With Air Travel Medical Emergencies. This also marks the end of our run as your hosts.

Show Notes Jeff: Welcome back to EMplify the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum and I’m back with Nachi Gupta for the 30th episode of EMplify and the first Post-Ponte Vedra Episode of 2019. I hope everybody enjoyed a fantastic conference. This month, we are sticking in the abdomen for another round of evidence-based medicine, focusing on Emergency Department Management of Patients With Complications of Bariatric Surgery. Nachi: As the obesity epidemic continues to worsen in America, bariatric procedures are becoming more and more common, and this population is one that you will need to be comfortable seeing. Jeff: Thankfully, this month’s author, Dr. Ogunniyi, associate residency director at Harbor-UCLA, is here to help with this month’s evidence-based article. Nachi: And don’t forget Dr. Li of NYU and Dr. Luber of McGovern Medical School, who both played a roll by peer reviewing this article. So let’s dive in, starting with some background. Starting off with some real basics, obesity is defined as a BMI of greater than 30. Jeff: Oh man, already starting with the personal assaults, I see how this is gonna go… Show More v Nachi: Nah! Just some definitions, nothing personal! Jeff: Whatever, back to the article… Obesity is associated with an increased risk of hypertension, hyperlipidemia, and diabetes. Rising levels of obesity and associated co-morbidities also lead to an increase in bariatric procedures, and thereby ED visits! Nachi: One study found a 30-day ED utilization rate of 11% for those undergoing bariatric surgery with an admission rate of 5%. Another study found a 1-year post Roux-en-y ED visit rate of 31% and yet another found that 25% of these patients will require admission within 2 years of surgery. Jeff: Well that’s kind worrisome. Nachi: It sure is, but maybe even more worrisome is the rising prevalence of obesity. While it was < 15% in 1990, by 2016 it reached 40%. That’s almost half of the population. Additionally, back in 2010, it was estimated that 6.6% of the US population had a BMI> 40 – approximately 15.5 million adults!! Jeff: Admittedly, the US numbers look awful, and honestly are awful, but this is a global problem. From the 80’s to 2008, the worldwide prevalence of obesity nearly doubled! Nachi: Luckily, bariatric surgical procedures were invented and honed to the point that they have really shown measurable achievements in sustained weight loss. Along with treating obesity, these procedures have also resulted in an improvement in associated comorbidities like hypertension, diabetes, NAFLD, and dyslipidemia. Jeff: A 2014 study even showed an up to 80% reduction in the likelihood of developing DM2 postoperatively at the 7-year mark. Nachi: Taken all together, the rising rates of obesity and the rising success and availability of bariatric procedures has led to an increased number of bariatric procedures, with 228,000 performed in the US in 2017. Jeff: And while it’s not exactly core EM, we’re going to briefly discuss indications for bariatric surgery, as this is something we don’t often review even in academic training programs. Nachi: According to joint guidelines from the American Society for Metabolic and Bariatric Surgery, the American Association of Clinical Endocrinologists, and The Obesity Society, there are three groups that meet indications for bariatric surgery. The first is patients with a BMI greater than or equal to 40 without coexisting medical problems. The second is patients with a BMI greater than or equal to 35 with at least one obesity related comorbidity such as hypertension, hyperlipidemia, or obstructive sleep apnea. And finally, the third is patient with a BMI of 30-35 with DM or metabolic syndrome though current evidence is limited for this group. Jeff: Based on the obesity numbers, we just cited – it seems like a TON of people should be eligible for these procedures. Which again reiterates why this is such an important topic for us as EM clinicians to be well-versed in. Nachi: As far as types of procedures go – while there are many, there are 3 major ones being done in the US and these are the lap sleeve gastrectomy, Roux-en-Y gastric bypass, and lap adjustable gastric banding. In 2017, these were performed 60%, 18%, and 3% of the time. Jeff: And sadly, no two procedures were created alike and you must familiarize yourself with not only the procedure but also its associated complications. Nachi: So we have a lot to cover! overall, these surgeries are relatively safe with one 2014 review publishing a 10-17% overall complication rate and a perioperative 30 day mortality of less than 1%. Jeff: Before we get into the ED specific treatment guidelines, I think it’s worth discussing the procedures in more detail first. Understanding the surgeries will make understanding the workup, treatment, and disposition in the ED much easier. Nachi: Bariatric procedures can be classified as either restrictive or malabsorptive, with restrictive procedures essentially limiting intake and malabsorptive procedures limiting nutrient absorption. Not surprisingly, combined restrictive and malabsorptive procedures like the Roux-en-y gastric bypass tend to be the most effective. Jeff: Do note, however that 2013 guidelines do not recommend one procedure over another and leave that decision up to local surgical expertise, patient specific risk factors, and treatment goals. Nachi: That’s certainly an important point for the candidate patient. Let’s start by discussing the lap gastric sleeve. In this restrictive procedure, 80% of the greater curvature of the stomach is excised producing early satiety and weight loss from decreased caloric intake. This has been shown to have both low mortality and a low overall rate of complications. Jeff: Next we have the lap adjustable gastric band. This is also a restrictive procedure in which a plastic band is placed laparoscopically around the fundus leaving behind a small pouch that can change in size as the reservoir is inflated and deflated percutaneously. Nachi: Unfortunately this procedure is associated with a relatively high re-operation rate – one study found 20% of patients required removal or revision. Jeff: Even more shockingly, some series showed a 52% repeat operation rate. Nachi: 20-50% chance of removal, revision, or other cause for return to ER - those are some high numbers. Finally, there is the roux-en-y gastric bypass. As we mentioned previously this is both a restrictive and a malabsorptive procedure. In this procedure, the duodenum is separated from the proximal jejunum, and the jejunum is connected to a small gastric pouch. Food therefore transits from a small stomach to the small bowel. This leads to decreased caloric intake and decreased digestion and absorption. Jeff: Those are the main 3 procedures to know about. For the sake of completeness, just be aware that there is also the biliopancreatic diversion with or without a duodenal switch, as well as a vertical banded gastroplasty. The biliopancreatic diversion is used infrequently but is one of the most effective procedure in treating diabetes, though it does have an increased risk of complications. Expect to see this mostly in those with BMIs over 50. Nachi: Now that you have a sense of the procedures, let’s talk complications, both general and specific. Jeff: Of course, it should go without saying that this population is susceptive to all the typical post-operative complications such as venous thromboembolic disease, atelectasis, pneumonia, UTIs, and wound complications. Nachi: Because of their typical comorbidities, CAD and PE are still the leading causes of mortality, especially within the perioperative period. Jeff: Also, be on the lookout for self-harm emergencies as patients with known psychiatric disorders are at increased risk following bariatric surgery. Nachi: Surgical complications are wide ranging and can be grouped into early and late complications. More on this later… Jeff: Nutritional deficiencies are common enough to warrant pre and postoperative screening. Thiamine deficiency is one of the most common deficiencies. This can manifest within 1-3 months of surgery as beriberi or later as Wernicke encephalopathy. Symptoms of beriberi include peripheral neuropathy, ataxia, muscle weakness, high-output heart failure, LE edema, and respiratory distress. Nachi: All of that being said, each specific procedure has it’s own unique set of complications that we should discuss. Let’s start with the sleeve gastrectomy. Jeff: Early complications of sleeve gastrectomy include staple-line leaks, strictures, and hemorrhage. Leakage from the staple line typically presents within the first week, but can present up to 35 days, usually with fevers, tachycardia, abdominal pain, nausea, vomiting sepsis, or peritonitis. This is one of the most serious and dreaded early complications and represents an important cause of morbidity with an incidence of 3-7%. Nachi: Strictures commonly occur at the incisura angularis of the remnant stomach and are usually due to ischemia, leaks, or twisting of the gastric pouch. Patients with strictures usually have n/v, reflux, and intolerance to oral intake. Jeff: Hemorrhage occurs due to erosions at the staple line, resulting in peritonitis, hematemesis, or melena. Nachi: Late complications of sleeve gastrectomies include reflux, which occurs in up to 25% of patients, and strictures, which lead to epigastric discomfort, nausea, and dysphagia. Jeff: I’m getting reflux and massive heartburn just thinking about all of these complications, or the tacos i just ate…. Next we have the Roux-en-Y bypass. Nachi: Early complications of the Roux-en-Y Gastric Bypass include anastomotic or staple line leaks, hemorrhage, early postoperative obstruction, and dumping syndrome. Jeff: Leak incidence ranges from 1-6%, usually occurring at the gastro-jejunostomy site. Patients typically present within the first 10 days with abdominal pain, nausea, vomiting, and the feeling of impending doom. Some may present with isolated tachycardia while others may present with profound sepsis – tachycardia, hypotension, and fever. Nachi: Similar to the sleeve, hemorrhage can occur both intraperitoneally or intraluminally. This may lead to hematemesis or melena depending on the location of bleeding. Jeff: Early obstructions usually occur at either the gastro-jejunal or jejuno-jejunal junction. Depending on the location, patients typically present either within 2 days or in the first few weeks in the case of the gastro-jejunal site. Nachi: If the obstruction occurs in the jejuno-jejunostomy site, this can cause subsequent dilatation of the excluded stomach and lead to perforation, which portends a very poor prognosis. Jeff: Next, we have dumping syndrome. This has been seen in up to 50% of Roux-en-Y patients. Nachi: Early dumping occurs within 10-30 minutes after ingestion. As food rapidly empties from the stomach, this leads to distention and increased contractility, leading to nausea, abdominal pain, bloating, and diarrhea. This usually resolves within 7-12 weeks. Jeff: Moving on to late complications of the roux-en y - first we have marginal ulcers. Peptic ulcer disease and diabetes are risk factors and tobacco use and NSAIDs appear to increase your risk. In the worse case, they present with hematemesis or melena. Nachi: Internal hernias, intussusception, and SBOs are also seen after Roux-en-y gastric bypass. Patients with internal hernias usually present late in the postoperative period following significant weight loss. Jeff: Most studies cite a rate of 1-3% for internal hernias, with mortality up to 50% if there is strangulation. Nachi: And unfortunately for us on the front lines, diagnosis can be challenging. Presenting symptoms may be vague and CT imaging may be negative when patients are pain free, thus laparoscopy may be needed to definitively exclude an internal hernia. Jeff: Strictures may occur both during the early and late period. Most are minor, but significant strictures may result in obstruction. Nachi: Trocar site hernias and ventral hernias are also late complications, usually found after significant weight loss. Jeff: Cholelithiasis is another very common complication of bypass surgery, occurring in up to one third of patients, usually occurring during a peak incidence period between 6-18 months. Nachi: For this reason, the current recommendation is that patients undergoing bypass be placed on ursodeoxycholic acid for 6 months preventatively. Jeff: Some even go as far as to recommend prophylactic cholecystectomy to prevent complications, but as of 2013, the recommendation was only ‘to consider’ it. Nachi: Nutritional deficiencies are also common complications. Vitamin D, B12, Calcium, foate, iron, and thiamine deficiencies are all well documented complications. Patients typically take vitamins postoperatively to prevent such complications. Jeff: And next we have late dumping syndrome, which is far more rare than the last two complications. In late dumping syndrome, 1-3 hours after a meal, patients suffer hypoglycemia from excessive insulin release following the food bolus entering the GI tract. Symptoms are those typical of hypoglycemia. Nachi: Lastly, let’s talk about complications of lap adjustable gastric band surgery. In the early post op period, you can have esophageal and gastric perforations, which typically occur during balloon placement. Patients present with abd pain, n/v, and peritonitis. These patients often require emergent operative intervention. Jeff: The band can also be overtightened resulting in distention of the proximal gastric pouch. Presenting symptoms include abd pain with food and liquid intolerance and vomiting. Symptoms resolves once the balloon is deflated. The band can also slip, allowing the stomach to move upward and within the band. This occurs in up to 22% of patients and can cause strangulation. Presentation is similar to bowel ischemia. Nachi: Later complications include port site infections due to repeated port access. The infection can spread into connector tubing and the peritoneal cavity causing systemic symptoms. Definitely start antibiotics and touch base with the bariatric surgeon. Jeff: The connector can also dislodge or rupture with time. This can present as an arrest in weight loss. It’s diagnosed by contrast injection into the port. Of note, this complication is less common due to changes in the technique used. Nachi: Much like early band slippage and prolapse, patients can also experience late band slippage and prolapse after weeks or months. In extreme cases, the patients can again have strangulation and symptoms of bowel ischemia. More mild cases will present with arrest in weight loss, reflux, and n/v. Jeff: The band can also erode and migrate into the stomach cavity. If this occurs, it usually happens within 2 years of the initial procedure with an incidence of 4-11%. Presenting symptoms here include epigastric pain, bleeding, and infections. You’ll want to obtain emergent imaging if you are concerned. Nachi: And lastly there are two rare complications worth mentioning from any gastric bypass surgery. These are nephrolithiasis, possibly due to increased urinary oxalate excretion or hypocitraturia, and rhabdomyloysis. Jeff: That was a ton of information but certainly valuable as most EM clinicians, even ones in practice for decades, are unlikely to have that depth of knowledge on bariatric surgery. Nachi: And truthfully these patients are complicated. Aside from the pathologies we just discussed, you also have to still bear in mind other abdominal conditions unrelated to their surgery like appendicitis, diverticulitis, pyelo, colitis, hepatitis, pancreatitis, mesenteric ischemia, and GI bleeds. Jeff: Moving on to my favorite - prehospital care - as always, ABCs first. Consider IV access and early IV fluids in those at risk for dehydration and intra-abdominal infections. In terms of destination, if it’s feasible and the patient is stable consider transport directly to the nearest bariatric center - early efforts up front will really expedite patient care. Nachi: Once in the ED, you will want to continue initial stabilization. Special considerations for the airway include a concern for a difficult airway due to body habitus. Make sure to position appropriately and preoxygenate the patients if time allows. Keep the patient upright for as long as possible as they may desaturate quickly when flat. Jeff: We both routinely raise the head of the bed for all of our intubations. This is ever more important for your obese patients to help maximize your chance of first pass success without significant desaturation. Nachi: And though I’m sure we all remember this from residency, it’s worth repeating: tidal volume settings on the ventilator should be based on ideal body weight, not actual body weight. At 6 to 8 mL/kg. Jeff: Tachycardic patients should make you concerned for hypovolemia 2/2 dehydration, sepsis, leaks, and blood loss. Consider performing a RUSH exam (that is rapid ultrasound for shock and hypotension) to identify the cause. A HR > 120 with abdominal pain should make you concerned enough to discuss urgent ex-lap with the surgeon to evaluate for the post op complications we discussed earlier. Nachi: If possible, obtain a view of the IVC also while doing your ultrasound to assess for volume status. But bear in mind that ultrasound will undoubtedly be more difficult if the patient has a large body habitus, so don’t be disappointed if you’re not getting the best views. Jeff: Resuscitation should be aimed at early fluid replacement with IV crystalloids for hypovolemic patients and packed RBC transfusions for patients presumed to be unstable from hemorrhage. No real surprises there for our listeners. Nachi: Once stabilized, gather a thorough history. In addition to the usual questions, ask about po intolerance, early satiety, hematemesis, and hematochezia. Definitely also gather a thorough surgical history including name of procedure, date, known complications post op, and name of the surgeon. Jeff: You might also run into “medical tourism” or global bariatric care. Patients are traveling overseas to get their bariatric care more and more frequently. Accreditation and oversight is variable in different countries and there isn’t a worldwide standard of care. Just an important phenomenon to be aware of in this population. Nachi: On physical exam, be sure to look directly at the belly, making note of any infections especially near a port-site. Given the reorganized anatomy and extent of soft tissue in obese patients, don’t be reassured by a benign exam. Something awful may be happening deeper. Jeff: This naturally brings us into diagnostic testing. Not surprisingly, labs will be helpful in these patients. Make sure to check abdominal labs and a lipase. Abnormal LFTs or lipase may indicate obstruction of the biliopancreatic limb in bypass patients. Nachi: A lactic acid level will help in suspected cases of hypoperfusion from sepsis or bowel ischemia. Jeff: And as we mentioned earlier, these patients are often at risk for ACS given their comorbidities. Be sure to check a troponin if you suspect cardiac ischemia. Nachi: If concerned for sepsis, draw blood cultures, and if concerned for hemorrhage, be sure to send a type and screen. Urinalysis and urine culture should be considered especially for early post op patients, symptomatic patients, or those with GU complaints. Jeff: And don’t forget the urine pregnancy test for women of childbearing age, especially prior to imaging. Nachi: Check an EKG immediately after arrival for any patient that may be concerning for ACS. A normal ekg of course does not rule out a cardiac cause of their presentation. Jeff: As for imaging, plain radiographs certainly play a role here. For patients with respiratory complaints, check a CXR. In the early postoperative period, there is increased risk for pneumonia. Nachi: Unstable patients with abdominal pain will benefit from an emergent abdominal series, which may show free air under the diaphragm, pneumatosis, air-fluid levels, or even dilated loops of bowel. Jeff: Of course don’t forget that intra abd air may be seen after laparoscopic procedures depending on how recently the operation was performed. Nachi: Plain x-ray can also help diagnose malpositioned or slipped gastric bands. But a negative study doesn’t rule out any of these pathologies definitively, given the generally limited sensitivity and specificity of x-ray. Jeff: You might also consider an upper GI series. Emergent uses include diagnosis of slipped or prolapsed gastric bands as well as gastric or esophageal perforations. Urgent indications include diagnosis of strictures. These can also diagnose gastric band erosions and help identify staple-line or anastomotic leaks in stable patients. Nachi: However, upper GI series might not be easy to obtain in the ED, so it’s often not the first test performed. Jeff: This brings us to the workhorse for diagnostic evaluation. The CT. Depending on suspected pathology, oral and/or IV contrast will be helpful. Oral contrast can help identify gastric band erosions, staple-line leaks, and anastomotic leaks. Leaks can be identified in up 86% of cases with oral contrast. Nachi: CT will also help diagnose internal hernias. You might see the swirl sign on CT, which represents swirling of the mesenteric vessels. This is highly predictive of an internal hernia, with a sensitivity of 78-100% and specificity of 80-90% according to at least two studies. Jeff: While CT is extremely helpful in making this diagnosis, note that it may be falsely negative for internal hernias. A retrospective review showed a sensitivity of 76% and a specificity of 60%. It also showed that 22% of patients with an internal hernia on surgical exploration had a negative CT in the ED. Another study found a false negative rate of 32%. What does all this mean? It likely means that a negative study may still necessitate diagnostic laparoscopy to rule out an internal hernia. Nachi: While talking about CT, we should definitely mention CTA for concern of pulmonary embolism. In order to limit contrast exposure, you might consider doing a CTA chest and CT of the abdomen simultaneously. Jeff: Next up is ultrasound. Ultrasound is still the first-line imaging modality for assessing the gallbladder and for biliary tract disease. And as we mentioned previously, ultrasound should be considered for your RUSH exam and for assessing the IVC. Nachi: We also should discuss endoscopy, which is the test of choice for diagnosing gastric band erosions. Endoscopy is also useful for evaluating marginal ulcers, strictures, leaks, and GI bleeds. Endoscopy additionally can be therapeutic for patients. Jeff: When treating these patients, attempt to contact the bariatric surgeon for guidance as needed. This shouldn’t delay imaging however. Nachi: For septic patients, make sure your choice of antibiotics covers intra-abdominal gram-negative and anaerobic organisms. Port-site infections require gram-positive coverage to cover skin flora. Additionally, give IV fluids, blood products, and antiemetics as appropriate. Jeff: Alright, so this month, we also have 2 special populations to discuss. First up, the kids. Nachi: Recent estimates from 2015-2016 put the prevalence of obesity of those 2 years old to 19 years old at about 19%. As obese children are at higher risk for comorbidities later in life and bariatric surgery remains one of the best modalities for sustained weight loss, these surgical procedures are also being done in children. Jeff: Criteria for bariatric surgery in the adolescent population is similar to that of adults and includes a BMI of 35 and major comorbidities (like diabetes or moderate to severe sleep apnea) or patients with a BMI 40 with other comorbidities associated with long term risks like hypertension, dyslipidemia, insulin resistance and impaired quality of life. Nachi: Despite many adolescents meeting criteria, they should be referred with caution as the long term effects are unclear and the adolescent experience is still in its infancy with few pediatric specific programs. Jeff: Still, the complication rate is low - about 2.3% with generally good clinical outcomes including improved quality of life and reducing or staving off comorbidities. Nachi: Women of childbearing age are the next special population. They are at particular risk because of the unique caloric and nutrient needs of a pregnant mother. Jeff: Pregnant women who have had bariatric surgery have an increased risk of perinatal complications including prematurity, small for gestational age status, NICU admission and low Apgar scores. However, these risks come with benefits as other studies have shown reduced incidence of pre-eclampsia, large for gestational age neonates, and gestational diabetes. Nachi: 2013 guidelines from various organizations recommend avoiding becoming pregnant for at least 12-18 months postoperatively, with ACOG recommending a minimum of 2 years. Bariatric surgery patients who do become pregnant require serial monitoring for fetal growth and higher doses of supplemental folate. Jeff: We also have 2 pretty cool cutting edge techniques to mention this month before getting to disposition. Nachi: Though these are certainly not going to be done in the ED, you should be aware of two new techniques. Recently, the FDA approved 3 new endoscopic gastric balloon procedures in which a balloon is inflated in the stomach as a means of simulating a restrictive procedure. Complications include perforation, ulceration, GI bleeding, and migration with obstruction. As of now, they are only approved as a temporary modality for up to 6 months. Jeff: And we also have the AspireAssist siphon, which was approved in 2016. With the siphon, a g tube is placed in the stomach, and then ⅓ of the stomach contents is drained 20 minutes after meals, thus limiting overall digested intake. Nachi: Pretty cool stuff... Jeff: Yup - In terms of disposition, decisions should often be made in conjunction with the bariatric surgical team. Urgent and occasionally emergent surgery is required for those with hemodynamic instability, anastomotic or staple line leaks, SBO, acute band slippage with dilatation of the gastric pouch, tight gastric bands, and infected port sites with concurrent intra abdominal infections. Nachi: And while general surgeons should be well-versed in these complications should the patient require an emergent surgery, it is often best to stabilize and consider transfer to your local bariatric specialty facility. Jeff: In addition to the need for admission for surgical procedures, admission should also be considered in those with dehydration and electrolyte disturbances, those with persistent vomiting, those with GI bleeding requiring transfusions, those with acute cholecystitis or choledococholithiasis, and those with malnutrition. Nachi: Finally, patients with chronic strictures, marginal ulcers, asymptomatic trocar or ventral hernias, and stable gastric band erosions can usually be safely discharged after an appropriate conversation with the patient’s bariatric surgeon. Jeff: Definitely a great time to do some joint decision making with the patient and their surgeon. Nachi: Exactly. Let’s close out with some Key points and clinical pearls. Jeff: Bariatric surgeries are being performed more frequently due to both their success in sustained weight loss and improvements in associated comorbidities. Nachi: There is an increased risk of postoperative myocardial infarction and pulmonary embolism after bariatric surgery. There is also an increased risk of self-harm emergencies after bariatric surgery, mostly in patients with known psychiatric co-morbidities. Jeff: Nutritional deficiencies can occur following bariatric surgery, with thiamine deficiency being one of the most common. Look for signs of beriberi or even Wernicke encephalopathy. Nachi: Staple-line leaks are an important cause of postoperative morbidity. Patients often present with abdominal pain, vomiting, sepsis, and peritonitis. Jeff: Strictures can also present postoperatively and cause reflux, epigastric discomfort, and vomiting. Nachi: Intraperitoneal or intraluminal hemorrhage is a known complication of bariatric surgery and may present as peritonitis or with hematemesis and melena. Jeff: After significant weight loss, internal hernias with our without features of strangulation are a late complication. Nachi: Late dumping syndrome is a rare complication following Roux-en-Y bypass occurring months to years postoperatively. It presents with hypoglycemia due to excessive insulin release. Jeff: Esophageal or gastric perforation are early complications of adjustable gastric band surgery. These patients require emergent surgical intervention. Nachi: Overtightening of the gastric band results in food and liquid intolerance. This resolves once the balloon is deflated. Jeff: Late complications of gastric band surgery include port-site infections, connector tubing dislodgement or rupture, band slippage or prolapse, and band erosion with intragastric migration. Nachi: Given the myriad of possible bariatric surgeries, emergency clinicians should be cognizant of procedure-specific complications. Jeff: Consider obtaining a lactic acid level for cases of suspected bowel ischemia or sepsis. Nachi: Endoscopy is the best method for diagnosing and treating gastric band erosions. Jeff: Septic patients should be treated with antibiotics that cover gram-negative and anaerobic organisms. Suspected port site or wound infections require gram positive coverage. Nachi: Pregnant patients who previously had bariatric surgery are at risk for complications from their prior surgery as well as pregnancy-related pathology. Jeff: A plain radiograph may be useful in unstable patients to evaluate for free air under the diaphragm, pneumatosis, air-fluid levels, or dilated loops of bowel. Nachi: CT of the abdomen and pelvis is the mainstay for evaluation. Oral and/or IV contrast should be considered depending on the suspected pathology. Jeff: Have a low threshold for emergent surgical consultation for ill-appearing, unstable, or peritonitic patients. Nachi: So that wraps up Episode 30!

Show Notes Jeff: Welcome back to EMplify the podcast corollary to EB Medicine’s Emergency medicine Practice. I’m Jeff Nusbaum and I’m back with Nachi Gupta for your regularly scheduled monthly dose of evidence based medicine. This month, we are tackling an incredibly important topic – Assessing abdominal pain in adults, a rational, cost effective, and evidence-based strategy. Nachi: This incredibly important topic was chosen to mark the 20th anniversary of Emergency Medicine Practice. It is actually a revision of the first issue of Emergency Medicine Practice in 1999, now with updated evidence and recommendations. Thanks Robert Williford and Dr. Colucciello for getting this all started 2 decades ago! Jeff: Wow – 20 years – that’s amazing considering Emergency Medicine as a specialty hadn’t even been around all that long at the time and as Dr. Jagoda writes in his intro “evidence based education was still finding its footing.” Nachi: As a tribute to the man who started it all, EB Medicine again turned to Dr. Colucciello, who is no longer wearing his editor in chief hat, but instead is a professor at the University of North Carolina School of Medicine, to update his original article with the latest evidence. Jeff: Before we dive into the meat and potatoes of this month’s issue, let me also recognize Drs. Taylor and Shaukat of Emory and Coney Island Hospital respectively for their efforts in peer reviewing this huge topic. Show More v Nachi: For a number of reasons, this month is going to be a little different. You will notice that we will focus more on safe disposition instead of on diagnosis. Which is reasonable, as that is the crux of our job as emergency physicians. Jeff: Indeed. So for those of you who can’t wait, here’s a quick spoiler, The CBC isn’t all that useful. CT is good but you really should learn ultrasound, and lastly, sick patients need prompt consultation and resuscitation, not rapid trips to radiology. Nachi: All valid points, but let’s dive in too some actual detail. Jeff: Abdominal pain is the one of most frequent complaint in US emergency departments, representing 8% of all adult ED visits, with admission rates for all patients with abdominal pain ranging between 18-42% and reaching as high as 60% for the elderly. Nachi: With respect to the elderly, statistically speaking, 20% presenting with abdominal pain will undergo surgery, and 5% will die. Jeff: Often the etiology of the abdominal pain is never determined. This happens up to 40% of the time by the end of the ED visit. Nachi: I feel like that needs to be restated for emphasis – nearly half of patients who present to the ED with abdominal pain will have no determined etiology for their pain. Clearly, that doesn’t mean you are a bad ED physician – it’s just the way it goes. Jeff: Definitely still a win to be told you aren’t having an intra-abdominal catastrophe at the end of your visit! Nachi: Moving on to pathophysiology. Visceral pain results from distention or inflammation of the hollow organs or from ischemia from any internal organ, while the more localized, somatic pain is typically from irritation of the adjacent peritoneum. Jeff: And don’t forget about referred pain. Due to the movement of organs and stretching of nerve pathways during fetal development, pain may be referred to distant sites, like diaphragmatic irritation presenting as shoulder pain. Nachi: Let’s talk differential diagnosis. The differential for abdominal pain is tremendously broad and includes both intra-abdominal and extra abdominal pathologies. Check out table 2 for a very thorough list. Jeff: Table 1 is also worth reviewing while you’re on page 3 as it lists a few of the common dangerous mimics that often lead to misdiagnosis on initial presentation. To highlight a few – a AAA can masquerade as renal colic, diverticulitis, or a lumbar strain; an ectopic may present similar to PID, a UTI, or a corpus luteum cyst, and mesenteric ischemia may present shockingly similar to gastroenteritis, constipation, ileus, or an SBO. Nachi: Though misdiagnosis is certainly possible at any age, one must be particularly cautious with the elderly. Abdominal pain in the elderly is complicated by a number of factors, they often have no fever, no leukocytosis, or no localized tenderness despite surgical disease, surgical problems progress more rapidly, and lastly, they are at risk for vascular catastrophes, which don’t typically afflict the younger population Jeff: Dr. Colucciello closes the section on the elderly with a really thought-provoking point – we routinely admit 75 year old with chest pain and benign exams, yet we readily discharge a 75 year old with abdominal pain and a benign exam even though the morbidity and mortality of abdominal pain in this group exceeds that of the chest pain group. Nachi: That’s an interesting perspective, but we still have to think about this in the context of what an admission would offer in either of these cases. Most of the testing for abdominal pain can be done in the ED, CT being the workhorse. This point certainly merits more thought though. Jeff: Most clinicians have a low threshold to scan their elderly patients with abdominal pain, and the data behind this practice is quite compelling. In one study, CT altered the admission decision in 26%, need for surgery in 12%, the need for antibiotics in 21%, and changed the suspected diagnosis in 45%. Nachi: That latter figure, 45% change in suspected diagnosis, that was also confirmed in another study in which CT revealed a clinically unsuspected diagnosis in 43% of the elderly. Jeff: And it’s worth mentioning, that even though CT may be the go-to-tool - biliary tract disease, which we know is best visualized on ultrasound, is actually the most common cause of abdominal pain, especially sudden onset abdominal pain in the elderly. Nachi: The next higher risk group to discuss are patients with HIV. While anti retroviral therapy has certainly decreased the burden of opportunistic infections, don’t forget to keep a broader differential in this group including bacterial enterocolitis, drug-induced pancreatitis, or AIDS related cholangiopathy Jeff: Definitely make sure to check to see if the patient has a recent CD4 count to give you a sense of their disease and what they may be at risk for. At less than 200, cryptosporidium, isospora, cyclospora, and microsporidium all make their way onto the differential in addition to the standard players. Nachi: For more information on HIV and its management, check out the February 2016 issue of Emergency Medicine Practice, which covered this and more in depth. Jeff: The next high risk population we are going to discuss are women of childbearing age. Step one is always the same - diagnose pregnancy! Always get a pregnancy test for women between menarche and menopause. Nachi: The pregnancy test is important not only for diagnosing an intrauterine pregnancy, but it’s also a reminder, that we need to consider and rule out an ectopic. Jeff: Along similar lines, you also need to consider torsion, especially in your pregnant population, as 20% of cases of ovarian torsion occur during pregnancy. Nachi: Unfortunately, you cannot rely on the physical exam alone in this age group, as the pelvic exam may be misleading. Up to a quarter of women with appendicitis can exhibit cervical motion tenderness -- a finding typically associated with PID. Sadly, errors are common and ⅓ of women of childbearing age who ultimately were found to have appendicitis were initially misdiagnosed. Jeff: To help reduce your risk in the pregnant population, consider imaging, particularly with radiation reduction strategies, including using ultrasound and MRI, which is gaining favor in the diagnosis of appendicitis in pregnancy. Nachi: Diagnosis of appendicitis, in a pregnant patient, ultrasound vs. mri. Sounds familiar. Didn’t we just talk about this in Episode 24 back in January? Jeff: We sure did! Take another listen if that doesn’t ring a bell. Nachi: That was focused on first trimester only, but while we’re talking about appendicitis in pregnancy - keep in mind that during the second half of pregnancy, the appendix has moved out of the RLQ and is more likely to be found in the RUQ. Jeff: As yes, the classic RUQ appendix. As if our jobs weren’t hard enough, now anatomy is changing… Anyway, the last high risk group we are going to discuss here are those patients with prior abdominal surgery. Make sure to ALWAYS examine the patient's exposed skin to look for scars. Adhesions are the leading cause of SBOs in the industrialized world, followed by malignancy, IBS, and internal or external hernias. Nachi: Also keep a high index of suspicion for patients who have undergone bariatric surgery. They are especially prone to surgical causes of abdominal pain including skin infections and surgical leaks. Jeff: For this reason, CT imaging should be done with IV and oral contrast, with those having undergone a Roux-en-Y receiving oral contrast on the CT table. Nachi: Perfect. Let’s move on to evaluation once in the ED! Jeff: As we mentioned a few times already - diagnosis is difficult, a comparison of initial and final diagnosis only has about 50-65% accuracy. For this reason, Dr. C suggests taking a ‘worst first’ approach to forming your differential and guiding your workup. Nachi: And as a brief aside, before we continue… Missed appendicitis is one of the three most common causes of emergency medicine malpractice lawsuits - with MI and fractures being the other two. That being said, you, as a clinician, have either missed appendicitis or likely will in the future. In a study of cases of misdiagnosed appendicitis brought to litigation, several themes recurred. For example, patients with misdiagnosed disease has less RLQ pain and tenderness as well as diminished anorexia, nausea, and vomiting. Jeff: Well that’s scary - I know I’ve already missed a case, but luckily, he returned thanks to good return precautions, which we’ll get to in a few minutes. Also, note that in addition to imaging and the physical exam, history is often the key to uncovering the cause of abdominal pain. Nachi: Not to harp on litigation, but in malpractice cases brought up for failure to diagnose abdominal conditions, deficiencies in data gathering and charting were often to blame rather than misinterpretation of data. Jeff: As no shocker here, getting a complete history remains tremendously important in your practice as an emergency clinician. A recurring theme of EMplify for sure. Nachi: In order to really nail this down, consider using a standardized history form -- or memorizing one. An example is shown in Table 1. Standardized forms have been shown to improve patient satisfaction and diagnostic accuracy. Jeff: An interesting question for your abdominal pain patient is to ask about the ride to the hospital. Experiencing pain going over a speed bump has been shown to be about 97% sensitive and 30% specific for appendicitis. So fairly sensitive, but not too specific. Nachi: That’s interesting and may help guide you, but it’s certainly no replacement for CT. And remember that you can have stump appendicitis. This can occur in the appendiceal remnant after an appendectomy and is found in about 0.15% of all appendectomies. Jeff: Alright, so on to the physical exam. Like always, let’s start with vital signs. An elevated temp can be associated with intra abdominal infection, but sensitivity and specificity vary greatly here. Always consider a rectal temp, as these are generally more reliable. Nachi: And remember that hypothermic patients who are septic have worse outcomes than those who are hyperthermic and septic. Jeff: Elevated respiratory rate can be due to pain or subdiaphragmatic irritation. However, it can also be due to hypoxia, sepsis, anemia, PE, or metabolic acidosis, so consider all of those also in your differential. Nachi: Moving on to blood pressure: frank hypotension should make you immediately think of a ruptured AAA or septic shock 2/2 an intra abd infection. You can also use the shock index, which as a reminder is simply the HR/SBP. In one study, a SI > 0.7 was sensitive for 28-day mortality in sepsis. Jeff: Speaking of HR, tachycardia can be a response to pain, anxiety, fever, blood loss, or sepsis. An irregularly irregular rhythm -- or a fib -- is an important risk factor for mesenteric ischemia in elderly patients. This is important to consider in your differential early as it may guide your imaging modality. Nachi: With vitals done, we can move on to the abdominal exam - it is rare that a serious abdominal condition will present without tenderness in a young adult patient, but remember that the elderly patient may not present with much tenderness at all due decreased peritoneal sensitivity. Abdominal tenderness that is greatest when the abdominal muscles are contracted is likely due to abdominal wall pain. This can be elicited by having the patient lift their head or let their legs off the bed. This finding is known as Carnett sign and is about 95% accurate for distinguishing abdominal wall pain from visceral abdominal pain. Jeff: Though tenderness itself is helpful, the location of tenderness can be misleading. Note that while 80% of patients with appendicitis have RLQ tenderness, 20% don’t. The old 80-20 rule! So definitely don’t let RLQ tenderness be your sole guide! Nachi: Voluntary guarding is due to fear, anxiety, or even a reaction to a clinician’s cold hands. Involuntary guarding (also called rigidity) is more likely to occur with surgical disease. Remember that rigidity may be a less common finding in the elderly despite surgical disease. Jeff: Peritoneal signs are the true hallmark of surgical disease. These include rebound pain, pain with coughing, pain with shaking the stretcher or pain with striking the patient’s heel. Rebound historically has been thought to be pathognomonic for surgical disease, but recent literature hasn’t found it to be all that useful, with one study claiming it has no predictive value. Nachi: As an alternative, consider the “cough test”. Look for evidence of posttussive abd pain (like grimacing, flinching, or grabbing the belly). Studies have found the cough sign to be 80-95% sensitive for peritonitis. Jeff: In terms of other sings elicited during the abdominal exam: The murphy sign, ruq palpation that causes the patient to stop a deep inspiration -- in one study had a sensitivity of 97%, but a specificity of just under 50%. The psoas sign, pain elicited by extending the RLE towards the back while the patient lies on their left side -- in one study had a specificity of 95%, but only had a sensitivity of 16%. Nachi: Neither the obturator sign (pain with internal rotation of the flexed hip) nor the rosving sign (pain in the RLQ by palpating the LLQ) have been rigorously studied. Jeff: Moving a bit further south, from the abdomen to the pelvis - let’s talk about the pelvic exam. Most EM training programs certainly emphasize the importance of the the pelvic exam for women with lower abdominal pain, but some recent papers have questioned its role. A 2018 study involving 288 women 14-20 years old found that the pelvic didn’t increase sensitivity or specificity of diagnosis of chlamydia, gonorrhea, or trichomoniasis when compared with history alone. Another study questioned whether the pelvic exam can be omitted in these patients with an early intrauterine pregnancy confirmed on ultrasound, but it was unable to reach a conclusion, possibly due to insufficient power. Nachi: While Jeff and I do find it valuable to elicit as much as information from the history as possible and take value in the possibility of omitting the pelvic in certain cases in the future, given the current evidence based medicine, we both agree with the author here. Don’t abandon the pelvic for these patients just yet! Jeff: While on this topic, we should also briefly mention a reminder about fitz-hugh-curtis syndrome, perihepatic inflammation associated with PID. Nachi: As for the digital rectal exam, this can certainly be of use when considering and diagnosing prostatitis, perirectal disease, stool impactions, rectal foreign bodies, and gi bleeds. Jeff: And let’s not forget the often overlooked scrotal and testicular exam. In men with abdominal or flank pain, this should always be considered. Testicular torsion often presents with isolated abdominal or flank pain. The scrotal exam will help diagnose inguinal and scrotal hernias. Nachi: Getting back to malpractice case reviews for a minute --- in a 2018 review involving testicular torsion, almost ⅓ of the patients with missed torsion had presented with abdominal pain --- not scrotal pain! In ⅕ of the cases, no testicular exam was performed at all. Also, most cases of missed torsion occured in patients under 25 years old. Jeff: Speaking of torsion, about 6% occur over the age of 31, so have an increased concern for this in the young. Of course, if concerned for torsion, consult urology immediately and consider manual detorsion. Nachi: And if you, like me, were taught to manually detorse by rotating in the lateral or open book direction, keep in mind that in a study of 200 males with torsion, ⅓ had rotated laterally, not medially. Jeff: Great point. And one last quick point here. Especially if you are unsure about the diagnosis, make sure to perform serial exams both in the ED and also in the next few days at their PCP’s office. In one study, a 30 hour later repeat exam for patients discharged with nonspecific abdominal pain resulted in a clinically relevant change in diagnosis and therapy in almost 25% of patients. Nachi: So that wraps up the physical. Let’s get into diagnostic studies, starting with lab work and everybody’s favorite topic... the cbc. Jeff: Yup, just the other day I was asked by a consultant “what’s the white count.” in a patient with CT proven appendicitis. Man, a small part of my soul dies every time this happens. Nachi: It appears you must have an evidenced based soul then. According to a few studies, anywhere from 10-60% of patients with surgically proven appendicitis have an initially normal WBC. So in some studies, it’s even worse than a coin flip. Jeff: Even worse, in children the CBC is less helpful. In children, an elevated WBC detects a mere 53% of severe abdominal pathology - so again not all that helpful. Nachi: That being said, at the other end of the spectrum, in the elderly, an elevated WBC may imply serious disease. Jeff: So let’s make this perfectly clear. A normal WBC should not be reassuring, but an elevated WBC, especially in the elderly, should be very concerning. Nachi: The CRP is up next. Though not used frequently, it’s still worth mentioning, as there is a host of data on it in the setting of abdominal pain. In one meta analysis, CRP was approximately 62% sensitive and 66% specific for appendicitis. Jeff: And while lower levels of CRP do not rule out positive findings, increasing levels of CRP do predict, with increasing likelihood, the chances of positive findings. Nachi: Next we have lipase and amylase. The serum lipase is the best test for suspected pancreatitis. The amylase adds limited value and should not be routinely ordered. Jeff: As for the lactate. The greatest value of a lactate level is to detect occult shock and sepsis. It is also useful to screen for visceral ischemia. Nachi: And the last lab test we’ll discuss is the UA. The urinalysis is a potentially misleading test. In two studies, 20-30% of patients with appendicitis also had hematuria with leukocytes and bacteria on their UA. In a separate study of those with a AAA, there was an 87% incidence of hematuria. Jeff: That’s pretty troubling. Definitely not great to diagnosis someone with hematuria and a primary GU problem, when their aorta is actually exploding. Nachi: And that’s a great reminder to always avoid premature diagnostic closure. Jeff: Also worth mentioning is that not all ureteral stones present with hematuria. At least 6% have no hematuria on microscopy. Nachi: Alright, so that brings us to imaging. First up: plain films. I’m going to quote this directly from the article since I think it's so important, ‘never rely on plain films to exclude surgical disease.” Jeff: This statement is certainly evidence based as in one study 40% of x-ray findings were inconsistent with the final diagnosis. In another study, 43% of patients with major surgical disorders had either normal or misleading plain film results. So again, the take home here is that XR cannot rule out surgical disease, and should not be routinely ordered except for in specific settings. Nachi: And perhaps the most important of all those settings is in the setting of possible free air under the diaphragm. In this case, an upright chest visualizing the area under the diaphragm would be the test of choice. But again, even this doesn’t rule out surgical disease as free air may be absent on plain films in ⅓ to ½ of patients who have already perfed. Jeff: Next we have everybody’s favorite, the ultrasound. Because of it’s low cost and ease of use, bedside ultrasound is gaining traction. And we’ve cited this and other similar studies in other issues, this is a skill emergency medicine physicians must have in this day and age and it’s a skill they can learn quickly. Nachi: Ultrasound can visualize most solid organs, but it is best suited for the Right upper quadrant and pelvis. In the RUQ, we are looking for wall thickening, pericholecystic fluid, ductal dilatation, and sonographic murphys sign. Jeff: In the pelvis, there is a role for both transabdominal and transvaginal to rule out ectopic and potentially rule in intrauterine pregnancy. I know the thought of performing your own transvaginal ultrasound may sound crazy to some, but we both trained in places where ED TVUS was the norm and certainly wasn’t that hard to learn. Nachi: Ah, the good old days of residency. I’m certainly grateful for the US tech where I am now though! Next up we have CT. CT scans are ordered in just under 30% of patients with abdominal pain. Jeff: It’s worth noting, that while many used to scan with triple contrast - oral, rectal and IV, recent literature has shown that IV contrast alone is adequate for the diagnosis of most surgical conditions, including appendicitis. Nachi: If you’re still working in a shop that scans for RLQ pain with oral or rectal contrast, definitely check out the 2018 american college of radiology appropriateness criteria that states that IV contrast is generally appropriate for assessing the RL. Jeff: And while we are on the topic of contrast, let’s dive a bit deeper into the, perhaps myth, that contrast leads to contrast induced nephropathy. Nachi: This is another really important point. Current data show that being ill enough to be admitted to the hospital is a risk factor for acute kidney injury and that IV contrast for CT does not add to that risk. In 2015, the american college of radiology noted in their manual on contrast media that the concern for the development of contrast induced nephropathy is not an absolute contraindication for using IV contrast. IV contrast may be necessary regardless of the risk of nephrotoxicity in certain clinical situations. Jeff: Ok, so contrast induced nephropathy may be real, but more studies and a definitive statement are still needed. Regardless, if the patient is sick and they need the scan with contrast, don’t hold back. Nachi: I think that’s a fair take home. As another note about the elderly, CT should be almost routine in the elderly patient with acute abdominal pain as it improves accuracy, optimizes appropriate hospitalization, and boosts ED management decision making confidence for this patient group. Jeff: If they are over 65, make sure you chart very carefully why they don’t need a scan. Nachi: Speaking of not needing a scan, two quick caveats on CT before moving to MRI. Unstable patients do not belong in a radiology suite - they belong in the ED resus bay to be resuscitated first. Prompt surgical consultation and bedside ultrasound if indicated are both a must in unstable patients. Jeff: The second caveat is on the other end of the spectrum - not all CT scanning is created equally - the interpretation depends on the scanner, the quality of the scan, and the experience and training of the reading radiologist. In one study, nearly 13% of abdominal CT scans may initially be misread. Nachi: So if you’re concerned, consider consultation or an extended ED observation to monitor for any changes in the patient’s status. Jeff: Next up is MRI - MRI has an ever expanding role in the ED. The accuracy of MRI to diagnose appendicitis is very similar to CT, so consider it in all pregnant patients, though ultrasound is still considered first line. Nachi: And finally let’s touch upon the ekg and ACS. In patients over 40 with upper abdominal pain, an EKG and troponin should always be considered. Jeff: Don’t be reassured by a response to a GI cocktail either - this does not exclude myocardial ischemia. Nachi: Next, let’s talk the role of analgesia in treating the undifferentiated abdominal pain patient. Jeff: While there was formerly a concern of ‘masking the pain’ with opiates, the evidence says otherwise. Pain medicine may even aid in the diagnosis, so definitely don’t withhold it in the setting of acute abdominal pain. Nachi: Wait I get that masking the pain is no longer considered a concern, but how would it aid in the diagnosis? Jeff: Good question. Analgesics might facilitate the gathering of history and allow a more complete physical exam by relaxing the abdominal musculature. Nachi: Ahh that makes sense. So certainly treat pain! Both morphine at 0.1 mg/kg and fentanyl at 1 mic/kg are appropriate analgesics for acute abdominal pain. In those that are a difficult stick, a recent study showed that 2 micrograms/kg of fentanyl via a nebulizer was a safe alternative. Remember, fentanyl is quick on, quick off, which may make it desirable in certain situations. It actually has the shortest time of onset of any opioid. It’s also safer in patients with a “marginal” blood pressure. Jeff: And just like the GI cocktail - response to opiate analgesics does not exclude serious pathology. These patients need serial exams and likely labs and imaging if their pain is so severe. Nachi: Few things are more important prior to discharge of an abdominal pain patient than documenting repeat exams and a PO trial. Jeff: True. You should also consider haloperidol for patients with gastroparesis and cannabinoid hyperemesis as a growing body of literature supports its use in such settings. Check out the August 2018 EMP or EMplify for more details if you’re curious. Nachi: The last analgesic to discuss is our good friend ketamine. Low dose ketamine at 0.3 mg/kg over 15 minutes is gaining traction as the analgesic of choice in many ED’s. Jeff: The key there, is that it must be given over 15 minutes. Ketamine has a great safety profile, but you make it so much safer and a much better experience if you give it slowly. Nachi: Before we get to disposition, let’s talk controversies and cutting edge - and there is just one this month - and that’s the use of the Alvarado score. Jeff: In the Alvarado score, you get two points for RLQ tenderness and 2 points for a leukocytosis over 10,000. You get an additional point for all of the following; rebound, temp over 99.1, migration of pain to the RLQ, anorexia, n/v, and a left shift. The max score is therefore 10. A score of 3 or less make appendicitis unlikely, 4-6 warrants CT imaging, and 7 or more a surgical consultation. Nachi: A 2007 study suggests that using the Alvarado score along with bedside ultrasound might allow for rapid and inexpensive diagnosis of appendicitis. Jeff: I don’t think we should change practice based on this just yet, but more ultrasound diagnosis may be on the horizon. If you want to start using the Alvarado score in your practice, MDcalc has a great easy to use calculator. Nachi: Let’s get to the final section. Disposition! Jeff: As we mentioned at the beginning of this episode, the diagnosis is less important than proper disposition. For patients with suspected ruptured AAA, torsion, or mesenteric ischemia - the disposition is easy - they need immediate surgical consultation and likely operative intervention. Nachi: For others, use the tools we outlined above - ct, us, labs, etc, to help support your decision. Keep in mind, that serial exams are a great tool and of little expense - so make sure to lay your hands on the patient's abdomen frequently, especially when the diagnosis is unclear. Jeff: For those that look well after a work up, with no clear diagnosis, it may be reasonable to discharge them home with prompt follow up, assuming prompt follow up is plausible. The key here is that these patients need good discharge instructions. Check out figure 2 on page 20 for a sample discharge template. Nachi: But if the patient is still uncomfortable, even after a thorough workup, there may be a role for ED observation units. In one study of 220 patients admitted for to ED obs units for serial exams, 39% eventually underwent surgery with only 5% having negative laparotomies. Jeff: This month’s issue wraps up with some super important time and cost effective strategies, so let’s see if we can quickly breeze through some of the most important points before closing out this episode. Nachi: First - limit your abdominal x-rays as they offer limited value and are rarely helpful except in the setting of perforation, when an early upright chest film should be used liberally. Jeff: Next - limit electrolyte testing especially in young adults with nausea, vomiting and diarrhea. In those 18 to 60, clinically significant electrolyte abnormalities occur in only 1% of those with gastro. Nachi: With respect to urine testing, urine cultures are rarely indicated for uncomplicated cystitis in young women. Along similar lines, don’t anchor on the diagnosis of UTI as other lower abdominal conditions often lead to abnomal urine studies. Jeff: In your alcoholic patients, although all should be approached with an abundance of caution, limit testing to repeat abdominal exams in your non-toxic appearing patient who is already tolerating PO. Nachi: For those with suspected renal colic, especially those with a history of renal colic, limit CT use and instead consider ultrasound to look for hydro. This approach is endorsed by ACEPs choosing wisely campaign. Jeff: But as a reminder, this is for low risk patients only. Anyone with signs of infection should also undergo CT imaging. Nachi: And lastly - consider incorporating bedside US into your routine. The US is fast and accurate and compares similarly to radiology, especially in the context of detecting acute cholecystitis. Jeff: Alright, so that wraps up the new material for this episode, let’s close out with some key points and clinical pearls. The peritoneum becomes less sensitive with aging, and peritonitis can be a late or absent finding. Be wary of early diagnostic closure and misdiagnosis with a mimic of a more severe and dangerous pathology. The elderly, immunocompromised, women of childbearing age, and patients with prior abdominal surgeries are all at a higher risk for misdiagnosis. Elderly patients can present without fever, leukocytosis, or abdominal tenderness, but still have surgical abdominal pathology. Consider diagnostic imaging in all geriatric patients presenting with abdominal pain. Consider plain film if you suspect a viscus perforation or for certain foreign body ingestions. Do not forget the pelvic exam, testicular exam, and rectal exam as part of your physical, when appropriate. Testicular torsion can present with abdominal pain only. If suspected, consult urology and consider manual detorsion. A normal white blood cell count does not rule out appendicitis or other intra-abdominal pathology. Serum amylase should not be used in your assessment of the abdominal pain patient. Lack of microscopic hematuria does not rule out renal colic. CT of the abdomen with IV contrast alone is enough for most surgical conditions including appendicitis. Oral and rectal contrast does not need to be routinely administered. The 2018 American College of Radiology (ACR) Appropriateness Criteria discuss concern for delay in diagnosis associated with oral contrast use and an increased rate of perforation. There is recent literature to support that IV contrast does not cause nephropathy. The ACR 2015 Manual on Contrast Media states that concern for contrast induced nephropathy is not an absolute contraindication, and IV contrast may be necessary in many situations. Ultrasound can be used to evaluate the aorta, gallbladder, kidneys, appendix, bowel, spleen, pancreas, uterus, and ovaries. Consider bedside ultrasound and emergency surgical consult for all unstable patients with abdominal pain. For stable pregnant patients with concern for appendicitis, start with an ultrasound. If inconclusive, order an MRI. Epigastric pain in an elderly patient should raise concern for ACS. An EKG and troponin should be considered. For analgesia in patients with gastroparesis or cannabinoid hyperemesis syndrome, haloperidol is considered first-line. Low-dose ketamine (0.3mg/kg over 15 minutes) may be a better choice than opiate analgesia for abdominal pain. Nachi: So that wraps up Episode 29!

Show Notes Jeff: Welcome back to EMplify, the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum, and I’m back with my co-host, Nachi Gupta. This month, we’re moving into uncharted territories for the podcast… we’re talking psychiatry Nachi: Specifically, we’ll be discussing Depressed and Suicidal Patients in the emergency department. Jeff: As a quick survey of our audience before we begin, how many of you routinely encounter co-morbid psychiatric conditions in your ED patients, especially depression? Nachi: That would certainly be all of our listeners! Jeff: And how many of you struggle to admit or transfer patients for a formal psychiatric eval? Show More v Nachi: Again, just about all of our listeners I’m sure! Jeff: And finally, how many of you wish there was a clearly outlined evidence-based approach to managing such patients to improve care and outcomes? Nachi: That would certainly be helpful. So now that we are all in agreement with just how necessary this episode is, let’s dive in. Jeff: This month’s issue was authored by Dr. Bernard Chang, Katherine Tezanos, Ilana Gratch and Dr. Christine Cha, who are all at Columbia University. Nachi: In addition, it was peer reviewed by Dr. Nicholas Schwartz of Mount Sinai School of Medicine in New York and Dr. Scott Zeller of the university of California-Riverside. Jeff: Quite the team, from a variety of backgrounds. Nachi: And just to put this topic into perspective - annually, there are more than 12 million ED visits for substance abuse and mental health crises. This represents nearly 12.5% of all ED visits. Of note, among these visits, nearly 650,000 individuals are evaluated for suicide attempt. Jeff: Looking more in depth, of the mental health complaints we see daily, mood disorders are the most common, representing 43%, followed by anxiety disorders, 26%, and then alcohol related conditions at 23% Nachi: And as is often the case, these numbers are likely underestimates, as many psychiatric complaints, especially depression, often go unnoticed by the patients and providers alike. In one study of patients who presented with unexplained chest and somatic complaints, 23% met the criteria for a major depressive episode. Jeff: Sad, but terrifying, though I suppose it all makes this issue so much more valuable. Nachi: Before we get to the evidence and an evidence-based approach, let’s start with some definitions. Jeff: Certainly a good place to start, but let me preface this with an important point - arriving at a specific psychiatric diagnosis in the ED is likely neither feasible nor realistic due to the obvious limitations, most namely, time - instead, you should focus on assessing and collecting information on the presenting symptoms and taking a comprehensive psychiatric and medical history. Nachi: According to DSM-5, to diagnose a major depressive disorder you must have 5 or more of the following: depressed mood, decreased interest or pleasure in most activities, body weight change, insomnia or hypersomnia, restlessness or slowing, fatigue, feelings of worthlessness or guilt, diminished ability to think or concentrate or indecisiveness, or finally recurrent thoughts of death and or suicide. In addition, at least 1 of the symptoms must be either a depressed mood or loss of interest. Jeff: These symptoms must last most of the day, nearly every day, for 2 weeks. Nachi: And these symptoms must cause clinically significant distress or impairment across multiple areas of functioning. Jeff: So those were criterion A and B. Criterion C, D, and E state that a MDD does not include factors from substance use or medical conditions, psychotic disorders, or manic episodes. Nachi: Once you’ve had the symptoms for 2 years with little interruption, you likely qualify for a persistent depressive disorder rather than a MDD. Jeff: And if your symptoms repeatedly co-occur around menses, this is more likely premenstrual dysphoric disorder. Nachi: Moving on to suicide and suicide related concepts. Suicidal ideation is the consideration or desire to kill oneself. Jeff: These can be active or passive thoughts, for example, “I don’t want to be alive” vs “I want to kill myself.” Nachi: Other important terms include, the suicide plan, suicide attempt, suicide gesture and nonsuicidal self-injury. The plan typically includes the how, where, and when a person will carry out their attempt. Jeff: A suicide gesture is an action or statement that makes others believe that a person wants to kill him or herself, regardless of the actual plan. Nachi: I think that’s good for definitions, let’s discuss some more epidemiology. Based on 2005 data, the prevalence of 1 month MDD was 5% with a lifetime prevalence of major depression of 13%. Jeff: If those figures seem a bit high, another CDC study found that in a general population survey of a quarter million people between 2006-2008, 9% met the criteria for major depression. Pretty big numbers... Nachi: Sadly, though outpatient visits for depression and suicide related complaints have decreased over the years, while ED visits remain stable, implying that the ED is a critical entry point for depressed and suicidal patients. Jeff: It’s important to also recognize at risk populations. In several studies, the prevalence of MDD is reported as being nearly twice as high in women as it is in men. Nachi: MDD is also much more common in younger adults, with a prevalence of about 20% in those under 65 and a prevalence of just 10% in those 65 and older. Jeff: Additionally, being never-married / widowed / or divorced, being black or hispanic, having poor social support, major life events, and have a history of substance abuse are all serious risk factors for depression. Nachi: In terms of suicidality, nearly half of depressed adults in one study felt that they wanted to die, with ⅓ having thought about suicide. Taking it one step further, somewhere between 14-31% of depressed adults have attempted suicide, and roughly 1 in 10 depressed adults ultimately die by suicide. Jeff: And while it seems crass to even mention the financial impact, the number is shocking - suicide has an estimated economic burden of $5.4 billion per year in the US. Nachi: That’s an incredible amount and much more than I would have guessed. Jeff: In terms specific risk factors for suicide and suicide related complaints - white men over 80 have the highest rate of suicide death in the US, with 51.6 deaths per year per 100,000 individuals. Nachi: You snuck in an important word there - suicide DEATH. While old people die the most from suicide, younger adults attempt suicide more often. Jeff: Along similar lines, while women attempt suicide nearly 4 times more frequently than men, men are 3 times more likely to die by suicide, likely related to their respective choice of suicide methods. Nachi: Lesbian, gay, and bisexual men or women are another at risk population, with rates of suicidal ideations being nearly twice that of their heterosexual counterparts Jeff: Despite the litany of risk factors we just ran through, the strongest single predictor for suicide related outcomes is a prior history of suicidal ideation or attempt, with individuals who have made a previous attempt being nearly 6 times more likely to make another. Nachi: And lastly, those who have had symptoms severe enough to warrant psychiatric admission have an increased lifetime risk of suicide also at 8.6% vs 0.5% for the general population, in one study. Jeff: Alright, so that wraps up the background, let’s move on to the actual evaluation. Nachi: When forming your differential, a crucial aspect is identifying potential secondary causes of depressive symptoms, as many depressive symptoms are driven by etiologies that require different management strategies and treatment. Be on the lookout for toxic-metabolic, infectious, neurologic disturbances, medication side effects, and recent medical events as the etiology for depressive episodes and suicidality. Jeff: Excellent point, which we’ll reiterate a few times throughout the episode - always be on the lookout for medical causes of new psychiatric symptoms. Next, we have my favorite, prehospital care - when doing your scene assessment, look out for possible signs of overdose such as empty pill bottles lying around. It’s also important to assess for the presence of firearms. Of course, this should not be done at the expense of acute medical stabilization. Nachi: And don’t forget to consider transport directly to institutions with full psychiatric services, especially for those with active suicidal ideations. Jeff: Once in the ED - start by maximizing the patient's privacy. Always use a nonjudgmental approach and use open-ended questions. Nachi: If feasible, map the chronology of depressive symptoms and their impact on the patient’s functional status. It’s also important to elicit any psychiatric history, including prior hospitalizations. Jeff: Screening for suicidality is critical in all patients with depressive symptoms given the elevated risk in this population. Though not broadly adopted in many EDs, there are a number of screening tools to assist you in this process, including the PHQ-9, ED SAFE PSS-3, and C-SSRS, which all asses for severity of suicide risk. These have been developed primarily for the outpatient and primary care settings. Nachi: And not surprisingly, MDCalc has online tools to help you use these risk assessments, so you can easily pull up a scoring tool on your phone should the appropriate clinical scenario arise. Jeff: The PHQ-9 was validated in various outpatient settings, including the ED. This is a self-administered depression questionnaire that has been found to be reliable across genders and different cultures. Interestingly, the PHQ-9 questionnaire contains one question about suicidality - how often is the patient bothered by thoughts that you would be better off dead or hurting yourself. Responding “nearly every day” increases your odds from 1 in 250 to 1 in 25 of attempting suicide. Nachi: The next tool to discuss is the ED-Safe PSS-3. The PSS-3 assesses for depression/hopelessness and suicidal ideations in the past 2 weeks as well as lifetime history of suicide attempt. Jeff: In one study, using this tool doubled the number of suicide-risk cases detected. Nachi: Once someone has screened positive for recent suicidal ideations, further screening must be done via a secondary screener. Jeff: In one study, following this approach decreased the total number of suicide attempts by 30% following an ED visit. Nachi: And what would you advise to clinicians that are concerned that questioning a patient about suicidal ideation may actually encourage or introduce the idea of suicide in those who hadn’t already considered it? Jeff: Great question - It has been found that there has been no associated introduction of negative effect when a patient is asked about suicidal ideations. Concerns about iatrogenic effects should not prevent such evaluations. Nachi: Definitely reassuring that this has been looked into. Let’s move on to the physical. Jeff: The physical exam should include a cognitive assessment that focuses on identifying medical conditions, as well as a behavioral mental health status exam that focuses on identifying the presence and degree of depression. Nachi: And as you said, we would mention it a few times -- In the ED, you always want to make sure you aren’t missing an underlying medical condition that manifests as depression. Jeff: So important. Alright, let’s move on to diagnostic studies. And thanks to a systematic review of 60 studies on this topic, there is actually reasonably good data here. Nachi: According to this review, in patients with a known psychiatric disease presenting with exacerbating psychiatric complaints, routine serum and urine tox screening is not recommended. Additional screening tests should be considered in those with new psychiatric symptoms who are 65 years or older, those who are immunosuppressed, and those with concomitant medical disease. Jeff: a 2017 ACEP clinical policy also recommends against routine lab testing in those with acute psychiatric complaints. They too call for a focused history and physical to guide testing. Nachi: It’s also worth highlighting one other incredibly important point from that ACEP policy - urine tox screens for drugs of abuse should not delay patient evaluation for transfer to a psychiatric facility. Jeff: Definitely a great policy to check out if you find yourself in all too frequent disagreements with your local psychiatric receiving facility. Nachi: You should also consider serum testing in those taking psychotropic medications with known toxic effects, such as lithium, as toxicity would change management. Jeff: Ok, last point about the work up, imaging studies of the brain should not be routinely ordered unless you have a high degree of suspicion. Nachi: That wraps up testing. Let’s move on to treatment. Jeff: First and foremost, you must maintain a safe environment. Effective precautions include alerts to staff about the potential safety risk in addition to searches of the patient and his / her belongings if applicable. Nachi: With the staff notified and the patient searched, the patient should be placed in a room without potentially dangerous items, like tubing or needles. Those who are at a very high risk may warrant continuous observation. Jeff: Speaking of safety, you will definitely want to engage in safety planning with the patient. Safety planning can be completed by any emergency clinician and should take about 20-45 minutes. Nachi: And while this is typically done by a psychologist or psychiatrist, this is something any emergency clinician can also easily do. Jeff: Safety planning beings with a brief interview. Next you establish a list of personalized and prioritized steps to help the patient through his or her next crisis. In a full plan, you should identify: warning signs, internal coping strategies, people and social settings that provide distraction, people whom the patient can ask for help, professionals or agencies whom the patient can contact during a crisis, and lastly how to make the environment safe (for example, lethal means counseling). Nachi: Of course, while the plan is meant to be a step by step approach for the patient, you should encourage the patient to seek professional help at any time if it is necessary. Jeff: Great point. And while safety planning typically is most effective when combined with other interventions, research suggests that it does enhance outpatient treatment engagement after an ED visit and in one study, reduce subsequent suicide attempts by 30% vs usual care. That’s a huge win for something that’s not that hard to do. Nachi: Similar to safety planning, let’s discuss no-suicide contracts. No-suicide contracts or no-harm contracts are verbal or written agreements between the patient and the clinician to articulate that he or she will not attempt to hurt him or herself. Though there isn’t a ton of evidence, at least one RCT showed that safety planning was superior to contracts. Jeff: Lethal-means counseling on the other hand is a potentially helpful prevention strategy. In lethal means counseling, you merely have to address the patient’s access to lethal means. By slowing their access to their lethal means, it is thought that the relatively short-lived suicidal crises may pass before they could access said means. Nachi: For example, you could provide options for restricting access to lethal means, such as disposal, locking up and giving the key to someone else, or temporarily giving the means to a friend. Jeff: And this may be a good time to involve friends and or family, especially when dealing with suicidal youths. Nachi: This is such an important and simple intervention that has actually been shown to reduce suicide attempts and deaths. Unfortunately, few ED clinicians address lethal means. Jeff: Pro tip: since most ED clinicians chart with templates, add something to your standard suicidality / psychiatric template about lethal means. This will serve as an important reminder to address it in real time. Nachi: That is a really great idea to ensure you don’t skip over this underutilized counseling. Jeff: The next aspect of treatment to discuss is follow up. Follow up is critical for both depressed and suicidal patients. Follow up can come in many forms and at a minimum should include the national suicide prevention lifeline. Nachi: The authors even simplify this for us a bit, providing 5 easy steps to help make sure patients follow through with ED discharge recommendations. Jeff: First, provide a standard handout that includes a list of outpatient providers. Next provide the patient the 24 hours crisis line number. After that, ask the patient to identify the most viable resources and address any barriers the patient may have in getting there. Next, schedule a follow up appointment, ideally within a week of discharge, and lastly, document the patient’s preferred follow up resources and steps taken to get them there. Nachi: And if this seems too burdensome for a single provider, think about identifying a staff member who may help the patient with follow up - perhaps a social worker or case manager. Follow up is so important, it’s critical that the ball not be dropped after you’ve put in so much hard work to make the plan. Jeff: As always, the team approach is preferred. Alright so the last treatment to discuss is actual pharmacotherapy. Since commonly prescribed antidepressants take up to 6-8 weeks to have a clinical effect, the administration of psychotropic medications is not routinely initiated in the ED. Interestingly, there may be a role for ketamine, yes, ketamine, in conjunction with oral meds. More on that in a few minutes though... Nachi: Let’s talk first about special populations - the only one we will discuss this month is military veterans. Jeff: Recent evidence has demonstrated an association between exposure to blast and concussive injuries and subsequent depressive and anxiety symptoms. Nachi: In part, because of this, among veterans presenting for emergency psychiatric services, approximately 52% reported suicidal ideations in the prior week and 70% reported current depressive symptoms. Clearly this is a major problem in this population. Jeff: But to bring it back to ED care, in one study, among depressed veterans with death by suicide, 10% had visited a VA ED in the 30 days prior to their death. Nachi: And this is in no way meant to be a knock-on VA ED docs - they are dealing with a very at risk population. But it is worth highlighting the importance of the ED visit as an excellent opportunity to begin to engage the patient in long term care. Jeff: Exactly, every ED visit is an opportunity that shouldn’t be missed. Nachi: Let’s talk controversies and cutting-edge topics from this issue. Jeff: First, let’s start by returning to ketamine and the treatment-resistant depression and suicidality. Nachi: Recent trials, including RCTs have found that low doses of ketamine administered via a variety of routes, may have a significant therapeutic effect towards reducing suicidality in patients in the acute setting. Jeff: To this end, Esketamine, an intranasal version of ketamine has already been FDA approved for treatment resistant depression. Nachi: This has huge implications for some of the psychiatrically sickest patients, so be on the lookout for more in the future. Jeff: Next we have the zero-suicide model. This is a program of the national action alliance for suicide prevention that involves a multi pronged approach to reducing suicide based on the premise that suicide is preventable. This model involves educating clinicians on best practices, identifying screening and assessment tools for engagement, treatment, and disposition. Nachi: Though not yet implemented in the ED setting, this may offer a novel approach to ED patients with psychiatric emergencies in the ED. Jeff: The next controversy is a big one - alcohol intoxication and suicide risk. There is a bidirectional relationship between depression and alcohol abuse and dependency. Not only is alcohol abuse a lifetime risk factor for completed suicide, those who make suicide attempts or present with suicidal ideations are more likely to be intoxicated. Nachi: In addition, formerly intoxicated patients may deny their previous thoughts and intentions when sober. Interestingly, though such patients have an increased lifetime risk of death by suicide. Jeff: Given this paradox and the evidence that exists, the authors recommend observing the patient until they have reached a reasonable level of sobriety. This effective level of sobriety should be based on clinical assessment and not blood alcohol levels. If the patient unfortunately has reached a place where they are at risk of withdrawal, this should be treated while in the ED. Nachi: It’s worth noting that ACEP guidelines and guidelines from the american association for emergency psychiatry have both supported a personalized approach that emphasize evaluating the patient’s cognitive abilities rather than a specific blood alcohol level to determine when to pursue a formal psychiatric assessment. Jeff: Very important point - in this high-risk population, you are targeting a clinical endpoint, not a laboratory end point and this is backed by several national guidelines. Nachi: Moving on to the next topic - let’s discuss post discharge patient contact. Jeff: Though not something many ED clinicians routinely do, this may be something to consider implementing in your department. And this doesn’t even have to be something as time consuming as a phone call. In one study, sending a brief postcard 9 times a year with a quick “hope things are well” type message to patients discharged after deliberate self-harm reduced self-poisonings by 50%. Nachi: Though other studies including other methods of follow up have not shown as drastic results, generally the results have shown a positive impact. Jeff: Next we have to discuss the various screening tools. Though we previously mentioned screening tools in a positive light, using such decision-making tools is still of limited utility due to the fact that they rely on self-reporting and suicidal thoughts and behaviors are complex and may require the consideration of hundreds of risk factors. Nachi: And while implicit association tests are being developed to predict suicidal thoughts and behaviors, and computer models and machine learning are being used to enhance our screening tools, there is still a long way to go before such tools perform more independently with acceptable performance. Jeff: The last cutting-edge topic to discuss is telepsychiatry. Nachi: Just as telestroke has changed stroke care forever, as technology advances, telepsychiatry may provide a solution to easily expand access to outpatient services and consultation in a cost effective manner - offering quick psychiatric care to those that never had access. Jeff: Let’s move on to the final section of the article. Disposition, which can be a bit complicated. Nachi: The decision for discharge, observation, or admission depends on clinical judgment and local protocols. Appropriate disposition is often fraught with legal, ethical, and psychological considerations. Jeff: It’s also worth noting that patients with suicidal ideations tend to have overall longer lengths of stay when compared to other patients on involuntary mental health hold. Nachi: There are however some suicide risk assessment tools that can help in the disposition decision planning such as C-SSRS, SAFE-T, and ICARE2. C-SSRS is a series of questions that assess the quality of suicidal ideation. SAFE-T is 5 step evaluation and triage tool that assesses various qualities and makes treatment recommendations. ICARE2 is provided by the American College of Emergency Physicians as a result of an iterative literature review and expert consensus panel. It also integrates many risk factors and treatment approaches. Jeff: It goes without saying that none of these tools are perfect. They should be used to assist in your clinical decision making. Nachi: For depressed but not actively suicidal patients, ensure close follow up with a mental health clinician. These patients typically do not require inpatient hospitalization. Jeff: Let’s also touch upon involuntary confinement here. Patients who are at imminent risk of self harm who refuse to stay for evaluation may need to be held involuntarily until a complete psychiatric and safety evaluation is performed. Nachi: Before holding a patient involuntarily, it is important to fully familiarize yourself with the state and county laws as there is wide variation. The period of involuntary confinement should be as short as possible. Jeff: With that, let’s close out this month’s episode with some high yield points and clinical pearls. Risk factors for major depression include female gender, young or old age, being divorced or widowed, black or Hispanic ethnicity, poor social support, and substance abuse. The strongest predictor for suicide-related outcomes is history of prior suicidal ideation or suicide attempt. When evaluating a patient with depressive symptoms, try to identify potential secondary causes, as this may influence your management strategy. When assessing for depression, perform a complete history and consider underlying medical causes that may be contributing to their presentation. Consider serum testing for the patient’s psychiatric medications if the medications have known toxic effects. 1. Routine serum testing and urine toxicology testing are not recommended for psychiatric patients presenting to the emergency department. Imaging of the brain should not be ordered routinely in depressed or suicidal patients. Depression places patients at a significantly increased risk for alcohol abuse and dependence. In addition to providing appropriate follow up resources to your depressed patients, emergency clinicians should consider making a brief follow up telephone call to the patient. Telepsychiatry may improve access to mental health providers and allow remote assessment and care from the ED. Suicide risk assessment tools such as C-SSRS, SAFE-T, and ICARE2 can help when deciding on disposition from the ER. It may be necessary to hold a patient against their will if they are at immediate risk of self-harm. Though not routinely administered in the ED for this purpose, psychotropic medications, such as ketamine, have proven helpful in acute depressive episodes. Patients who are actively suicidal should be admitted to a psychiatric observation unit or inpatient psychiatric unit. Nachi: So that wraps up Episode 28!

Show Notes Jeff: Welcome back to EMplify, the podcast corollary to EB Medicine's Emergency Medicine Practice. I'm Jeff Nusbaum, and I'm back with my co-host, Nachi Gupta. This month, we're moving from the trauma bay back to a more private setting, to discuss Emergency Department Diagnosis and Treatment of Sexually Transmitted Diseases. Nachi: And for those of you who follow along with the print issue and might be reading in a public place, this issue has a few images that might not be ideal for wandering eyes. Jeff: I'd say we need a “not safe for work” label on this episode, though I think we are one of the unique workplaces where this is actually quite safe. Nachi: And we're obviously pushing for “safe” practices this month. The article was authored by Dr. Pfenning-Bass and Dr. Bridges from the University of South Carolina School of medicine. It was edited by Dr. Borhart of Georgetown University and Dr. Castellone of Eastern Connecticut Health Network. Jeff: Thanks, team for this deep dive. Nachi: STDs or STIs are incredibly common and often under recognized by both the public and health care providers. Jeff: In addition, the rates of STDs in the US continue to rise, partly due to the fact that many patients have minimal to no symptoms, leading to unknowing rapid spread and an estimated 20 million new STDs diagnosed each year. Treating these 20 million cases amounts to a whopping $16 billion dollars worth of care annually. Nachi: 20 million! Kinda scary if you step back and think about it. Jeff: Definitely, perhaps even more scary, undiagnosed and untreated STDs can lead to infertility, ectopic pregnancies, spontaneous abortions, chronic pelvic pain and chronic infections. On top of this, there is also growing antibiotic resistance, making treatment more difficult. Nachi: All the more reason we need evidence based guidelines, which our team from South Carolina has nicely laid out after reviewing 107 references dating back to 1990, as well as guidelines from the CDC and the national guideline clearinghouse. Jeff: Alright, so let's start with some basics: pathophysiology, prehospital care, and the H&P. STDs are caused by bacteria, viruses, or parasites that are transmitted vaginally, anally, or orally during sexual contact, or passed from a mother to her baby during delivery and breastfeeding. Nachi: In terms of prehospital care, first, make sure you are practicing proper precautions and don appropriate personal protective equipment to eliminate or reduce the chance of bloodborne and infectious disease exposure. In those with concern for possible sexual assault, consider transport to facilities capable of performing these sensitive exams. Jeff: As in many of the prehospital sections we have covered -- a destination consult could be very appropriate here if you're unsure of the assault capabilities at your closest ER. Nachi: And in such circumstances, though patient care comes first, make sure to balance medical stabilization with the need to protect evidence. Jeff: Exactly. Moving on to the ED… The history and physical should be conducted in a private setting. For the exam, have a chaperone present, whose name you can document. The “5 Ps” are a helpful starting point for your history: partners, practices, prevention of pregnancy, protection from STDs, and past STDs. Nachi: 5 p's, I actually haven't heard this mnemonic before, but I like it and will certainly incorporate it into my practice. Again, the 5 p's stand for: partners, practices, prevention of pregnancy, protection from STDs, and past STDs. After you have gathered all of your information, make sure to end with an open ended question like “Is there anything else about your sexual practices that I need to know?” Jeff: Though some of the information and even the history gathering may make you or the patient somewhat uncomfortable, it's essential. Multiple partners, anonymous partners, and no condom use all increase the risk of multiple infections.

After you have gathered all of your information, make sure to end with an open ended question like “Is there anything else about your sexual practices that I need to know?” Jeff: Though some of the information and even the history gathering may make you or the patient somewhat uncomfortable, it’s essential. Multiple partners, anonymous partners, and no condom use all increase the risk of multiple infections. Try to create a rapport that is comfortable and open for your patient to provide as much detail as they can. Nachi: And as with any infectious work up, tachycardia, hypotension, and fever should all raise the concern for possible sepsis. In your sepsis source differential, definitely consider PID in addition to the usual sources. As a mini plug for a prior issue, PID was actually covered in the December 2016 issue of Emergency Medicine Practice, in detail. Jeff: Getting back to the physical exam: though some question the utility of the pelvic exam as our diagnostics get better, the literature suggests the pelvic definitely still has a big role both in diagnosing and differentiating STDs and other pathology. Don’t skip this step when indicated. Nachi: Now that we have a broad overview, let’s talk about specific STDs, covering diagnosis, testing, and treatment. Jeff: If following along in the article, appendices 1, 2 and 3, list detailed physical exam findings for the STDs were going to discuss, while table 3 lists treatment options. A great resource to use while following along or as a reference during a clinical shift! Nachi: First up, let’s talk chlamydia, the most common bacterial cause of STDs, with 1.7 million reported infections in 2017. Most are asymptomatic, which increases spread, especially in young women. Jeff: Chlamydia trachomatis has a 2-3 day life cycle in which elementary bodies enter endocervical and urethral cells and replicate, eventually causing host cell wall rupture and further spread. Nachi: Though patients with chlamydia are often asymptomatic, cervicitis in women and urethritis in men are the most common presenting symptoms. Vaginal discharge is the most common exam finding followed by cervical ectropion, endocervical mucus, and easily induced bleeding. Other presenting symptoms include urinary frequency, dysuria, PID, or even Fitz-Hugh-Curtis syndrome, which is a PID induced perihepatitis. In men, epididymitis, prostatitis, and proctitis are all possible presenting symptoms also. Jeff: And of note, chlamydia can also cause both conjunctivitis and pharyngitis. Nachi: This article has a ton of helpful images. Check out figures 1 and 2 for some classic findings with chlamydial infections. Jeff: When testing for chlamydia, nucleic acid amplification is the test of choice as it has the highest sensitivity, 92% when tested from a first-catch urine sample vs. 97% from a vaginal sample. While these numbers are similar, and you’re gut may be to forego the pelvic exam, consider the pelvic exam to aid in the diagnosis of PID and to evaluate for cervicovaginal lesions or other concomitant stds. Nachi: Similarly, in men, the test of choice is also a nucleic acid amplification test, with a first catch urine preferred over a urethral swab. Jeff: And lastly, nucleic acid amplification is also the test of choice from rectal and oropharyngeal samples, though you need to check with your lab first as nucleic acid amplification is not technically cleared by the FDA for this indication. Nachi: Treatment for chlamydia is simple, 1g of azithromycin, or doxycycline 100 mg BID x 7 days. Fluoroquinolones are a second line treatment modality. Jeff: In pregnant women, chlamydia can lead to ectopic pregnancy, premature rupture of membranes, and premature delivery. The single 1g azithromycin dose is also safe and effective with amox 500 mg TID x 7 days as a second line. Pregnant women undergoing treatment should have a documented test-of cure 3-4 weeks after treatment. Nachi: Next up, we have gonorrhoeae, the gram-negative diplococci. Gonorrhea is the second most commonly reported STD, affecting 0.8% of women and 0.6% of men, with over 500,000 reported cases in 2017. Jeff: Gonorrhea attaches to epithelial cells, altering the surface structures leading to penetration, proliferation and eventual systemic dissemination. Nachi: Though some may be asymptomatic, women often present with cervicitis, vaginal pruritis, mucopurulent discharge, and a friable cervical mucosa, along with dysuria, frequency, pelvic pain and abnormal vaginal bleeding. Jeff: Men often present with epididymitis, urethritis, along with dysuria and mucopurulent discharge. Proctitis, pharyngitis, and conjunctivitis are all possible complications. Nachi: In it’s disseminated form, gonorrhea can lead to purulent arthritis, tenosynovitis, dermatitis, polyarthralgias, endocarditis, meningitis, and osteomyelitis. Jeff: In both men and women the test of choice for gonorrhea again is NAAT, with endocervical samples being preferred to urine samples due to higher sensitivity. In men, urethral and first catch urine samples have a sensitivity and specificity of greater than 97%. Nachi: And as with chlamydial samples, the FDA has not approved gonorrhea NAAT for rectal and oropharyngeal samples, but most labs are able to process these samples. Jeff: Yeah, definitely check before you go swabbing samples that cannot be run. Lastly, in regards to testing, though it won’t likely change your management in the moment, the CDC does recommend a gonococcal culture in cases of confirmed or suspected treatment failure Nachi: It’s also worth noting that although NAAT can be used in children, but culture is additionally preferred in all settings due to legal ramifications of sexual abuse. Jeff: It pains me just to think about how awful that is. Ugh. Moving on to treatment: when treating gonorrhea, the current recommendation is to treat both with cefitriaxone and azithro. 250 mg IM is the preferred dose, up from just 125 mg IM which was preferred dose two decades ago along with 1g of azithro. Nachi: And if ceftriaxone IM cannot be administered easily, 400 mg PO cefixime is the second line treatment of choice. If there is a documented cephalosporin allergy, PO gemifloxacin or gentamycin may be used. And for those with an azithomycin intolerance, a 7 day course of doxycycline may be substituted instead. Jeff: In pregnant women, gonococcal infections are associated with chorioamnionitis, premature rupture of membranes, preterm birth, low birth weight, and spontaneous abortions. Pregnant woman therefore should be treated with both ceftriaxone and azithro in the same manner as their non pregnant counterparts. Nachi: There is also one quick controversy to discuss here. Jeff: oh yeah, go on… Nachi: The CDC currently recommends the IM dose of ceftriaxone, not IV. And this is because of the depot effect. However, it’s unclear if this effect is in fact true, as IM and IV ceftriaxone levels measured in blood 24 hours later are similar. So if the patient has an IV already, should we just give the ceftriaxone IV instead of IM? Jeff: I think it is probably okay, but I’ll wait for a bit more research. For now, I would continue to stick with the CDC recommendation of IM as the correct route. Nachi: And with the continuing rise of STD’s and the public health and economic burden we are describing here, I think the IM route, which is known to be effective, should still be used -- until the CDC changes their recommendations. Next up we have the great imitator/masquerader, syphilis, caused by the spirochete Treponema pallidum. LIke the other STDs we’ve discussed so far, cases of syphilis are also on the rise with over 30k cases in 2017, a 10% increase from 2016. Jeff: Syphilis is spread via direct contact between open lesions and microscopic abrasions in the mucous membranes of vagina, anus, or oropharynx. The organism then disseminates via the lymphatics and blood stream. Nachi: Infection with syphilis comes in three stages. Primary syphilis is characterized by a single, painless lesion, or chancre, which occurs about 3 weeks after inoculation. 6-8 weeks later, secondary syphilis develops. This often presents with a rash, typically on the palms and soles of the feet, or with condyloma lata, or lymphadenopathy. Jeff: Tertiary syphilis doesn’t appear until about 20 years post infection and it includes gummatous lesions and cardiac involvement including aortic disease. Nachi: Patients at any stage may go long periods without any symptoms, which is known as latent syphilis. In addition, at any stage a patient may develop neurosyphilis, which can present with strokes, altered mental status, cranial nerve dysfunction, and tabes dorsalis. Jeff: In early syphilis, dark-field examination is the definitive method of detection, though this is impractical in the ED setting. There are, instead, 2 different algorithms to follow. The CDC traditional algorithm recommends a nontreponemal test like rapid plasma reagin or RPR or the venereal disease research lab test also called VDRL, followed by confirmational treponemal test (fluoresent treponemal antibody absorption or FTA-ABS or T pallidum passive agglutination also called TP-PA). More recently there has been a shift to the reverse sequence, with screening with a treponemal assay followed by a confirmatory nontreponemal assay. Nachi: The reason for the change is that there is an increased availability of rapid treponemal assays. And where available, the reverse sequence offers increased throughput and the ability to detect early primary syphilis better. The CDC, however, still recommends the traditional testing pathway -- that is nontreponemal tests first like RPR or VDRL, followed by treponemal tests like FTA-ABS or TP-PA. The article also notes that emergency clinicians should rely on clinical manifestations in addition to serologic testing, when determining whether to treat for syphilis. Jeff: For neurosyphilis, the CSF-VDRL test is highly specific but poorly sensitive. In cases of a negative CSF-VDRL but still with high clinical suspicion, consider a CSF FTA-ABS test, which has lower sensitivity, but is also highly specific and may catch the diagnosis. Nachi: Treatment for primary, secondary, and early latent syphilis is with 2.4 million units of Penicillin G IM. For ocular and neurosyphilis, treatment is with 18-24 million units of pen G IV every 4 hours or continuously for 10-14 days. In patients who have a penicillin allergy, skin testing and desensitization should be attempted rather than azithromycin due to concerns for resistance. Jeff: For pregnant women, PCN is the only proven therapy. Interestingly, there is some evidence to suggest that a second IM dose may be beneficial in treating primary and secondary syphilis in pregnancy though data are limited. Nachi: We also have to mention the Jarisch-Herxheimer reaction before moving on. This is a syndrome of fevers, chills, headache, myalgias, tachycardia, flushing and hypotension following high dose PCN treatment due to a massive release of endotoxins when the bacteria die. This typically occurs in the first 12 hours but can occur up to 24 hours after treatment. Treatment is supportive. Concern of this reaction should never delay PCN treatment!! Jeff: The next condition to discuss is Bacterial vaginosis, or BV, which, interestingly, is not always an STD. It is therefore critically important to choose your words wisely when speaking with a patient who has BV. Nachi: That is an important point that is worth repeating. BV is not always an STD. So what is BV? BV occurs when there is a decrease or absence of lactobacilli that help maintain the acidic pH of the vagina leading to an overgrowth of Gardnerella, bacteroides, ureaplasma and mycoplasma. BV does not occur in those who have never had intercourse and it may increase the risk of other STDs and HIV. Jeff: 50% of women with BV are asymptomatic, while the others will have a thin, grayish-white, homogeneous vaginal discharge with a fishy smell, along with pruritis. Nachi: To diagnose BV, most use the amsel criteria, which requires 3 of following 4: 1) a thin, milky, homogeneous vaginal discharge, 2) the release of a fishy odor before or after the addition of potassium hydroxide, 3) a vaginal pH > 4.5, and 4) the presence of clue cells in the vaginal fluid. These criteria are 90% sensitive and 77% specific, with clue cells being the most reliable predictor. Jeff: And for those of us without immediately available microscopy, you can make the diagnosis based on characteristic vaginal discharge alone. Treat with metronidazole, 500 mg BID for 7 days, metronidazole gel, or an intravaginal applicator for 5 days, with the intravagainal applicator being better tolerated than the oral equivalent Nachi: BV in pregnancy increases risk of preterm birth, chorioamnionitis, postpartum endometriitis and postcesarean wound infections. Pregnant patients are treated the same as nonpregnant or with 400 mg of clindamycin BID x 7 days. Jeff: Always nice when there is really only one treatment regimen across the board. And that will be a general theme for treatment options in pregnancy with a few exceptions. Nachi: Next up we have Granuloma inguinale, or donovanosis, which is caused by Klebsiella granulomatis. Jeff: Granuloma inguinale is endemic to India, the Caribbean, central australia, and southern africa. It is rarely diagnosed in the US. Nachi: Granuloma inguinale presents with highly vascular, ulcerative lesions on the genitals or perineum. They are typically painless and bleed easily. If disseminated, Granuloma inguinale can lead to intra-abdominal organ and bone lesions and elephantiasis-like swelling of the external genitalia. Jeff: Granuloma inguinale can can be diagnosed by microscopy from the surface debris of purulent ulcers. Nachi: Once you have the diagnosis, the CDC recommends treatment with azithromycin for at least 3 weeks and until all lesions have resolved. Jeff: Next we have lymphogramuloma venereum or LGV. Nachi: LGV is a C. Trachomatis infection of the lymphatics and lymph nodes. This is predominantly a disease of the tropics and subtropical areas of the world. Jeff: On exam, in the primary stage, you would expect a small, painless papule, pustule, nodule or ulcer on the coronal sulcus of the penis or on the posterior forchette, vulva, or cervix of women. The primary stage eventually progresses to the secondary stage, which is characterized by unilateral lymphadenopathy with fluctuant, painful lymph nodes known as buboes. Nachi: Check out figure 11 for a great classic image of the “groove sign” which is involvement of both the inguinal and femoral lymph nodes, and is seen in 15-20% of cases. And actually even more common than the groove sign is a presentation with proctitis. Jeff: Testing for LGV should be based on high clinical suspicion, and NAAT should be performed on a sample from the primary ulcer base or from aspirate from a bubo. Nachi: Treatment for LGV is with doxycycline 100 mg BID x 21 days. Jeff: So, to summarize, for LGV, remember painful lymphadenopathy, especially in those with proctitis. Treat with doxy. Nachi: Next we have Mycoplasma genitalium, which causes nongonococcal urethritis in men and mucopurulent cervicitis and PID in women. Jeff: Unfortunately, there is no diagnostic test for M. genitalium, and it should be considered clinically, especially in the setting of recurrent urethritis. Nachi: Treat with azithro, but not 1g x 1. Instead, M. Genitalium should be treated with a course of azithro, with 500 mg on day 1 followed by 250 mg daily for 4 days. Moxifloxacin is an alternative. Jeff: Simple enough. Moving on to everybody’s favorite, genital herpes. Nachi: umm, I’m not sure sure anybody would call herpes their favorite. Why would you even say that? Jeff: i don’t know, seemed natural at the time… Regardless, primary genital herpes is caused by either HSV1 or HSV2. Though only an estimate, and likely an underestimate at that, it is estimated that at least 1 in 6 people in the US between 14 and 49 have genital herpes. Nachi: That’s much higher than I would have thought. Jeff: Patients usually contract oral herpes from HSV-1 due to nonsexual contact with saliva and genital herpes due to sexual contact with an infected person. Nachi: Keep in mind, however, that HSV1 can and will also cause genital infections if spread via oral sex. Jeff: Localized symptoms include pain, itching, dysuria, and lymphadenopathy and systemic symptoms include fever, headache, and malaise. In women, look for herpetic vesicles on the external genitalia along with tender ulcers in areas of rupture, see figure 12 for a characteristic image. Nachi: Though symptoms tend to be more severe in woman, men may present with vesicles on the glans penis, penile shaft, scrotum, perianal area, and rectum or even with dysuria and penile discharge. Jeff: HSV1 and 2 infections also have the ability to recur, though recurrences tend to become less frequent and severe over time. Nachi: It’s noteworthy that there is also a direct correlation between stress levels and the severity of an HSV outbreak. Jeff: Herpes can be diagnosed by viral culture of an unroofed vesicle or by NAAT. PCR based assays can also differentiate between HSV1 and HSV2 Nachi: While there is no cure, antivirals may help prevent and shorten outbreaks. Ideally you should begin treatment within 72 hours of lesion appearance. Treat with acyclovir, valacyclovir, or famciclovir. In addition, don't forget about adjuncts like analgesia, sitz bathes, and urinary catheter placement for severe dysuria. Jeff: HSV can also be vertically transmitted from mother to child so in pregnancy, treat with acyclovir 400 mg 3x/day for 7 days or valacyclovir Nachi: And because transmission is so easy, babies born to mothers with active lesions should be delivered by cesarean section. Jeff: Let’s move on to human papillomavirus, or HPV. There are over 100 types of HPV with 40 being transmitted through skin to skin contact, typically via vaginal and anal intercourse. Nachi: Most infections are asymptomatic and clear within 2 years. Jeff: Right, but one of the main reasons this is such a big deal is that HPV types 16 and 18 are oncogenic strains and can lead to cervical, penile, vulvar, vaginal, anal, and oropharyngeal cancers. Amazingly, HPV is responsible for more than 95% of the cervical cancers in women. Nachi: Hence the importance of the new vaccine series that most young adults and children are now opting for. Vaccination should occur in women through age 26 or men through age 21 if not previously vaccinated. Jeff: Critically important to take advantage of a vaccine that can prevent cancer! Nachi: And though not as important in terms of health consequences, just be aware that HPV 6 and 11 may lead to anogenital warts, known as condyloma acuminata. Jeff: In terms of exam findings, as you just mentioned, most infections are asymptomatic and self-limited. If symptoms do develop, HPV typically causes those cauliflower like or white plaque like growths lesions on the external genitalia, perineum, and perianal skin. Nachi: For testing, there is a limited role in the ED. Diagnosis should be made by visual inspection, followed eventually by a biopsy. Jeff: And just like the biopsy, which is unlikely to be done in the emergency department, most treatment is also not ED based. Treatment options include cryotherapy, immune-based therapy, and surgical excision, which has both the highest success rates and lowest recurrence. Nachi: Next up, we have trichomoniasis. Jeff:Trichomoniasis is a single-celled, flagellated, anaerobic protozoa, that directly damages the epithelium, causing microulcerations in the vagina, urethra, and paraurethral glands. Nachi: With an estimated 3.7 million infected people in the US, this is something you’re also bound to see. Jeff: Risk factors include recent or current incarceration, IV drug use, and co-infection with BV. Nachi: Note the common theme here - co infection. It’s very common for patients to have more than one STD, so make sure not to anchor when you think you’ve nailed the diagnosis. Jeff: On exam the majority of both women and men are asymptomatic. In women, you may find a purulent, frothy vaginal discharge, vaginal odor, vulvovaginal irritation, itching, dyspareunia, and dysuria Nachi: And don’t forget about the classic colpitis macularis, or the strawberry cervix. Though this is frequently taught and stressed, it’s actually only seen in 2-5% of infected women. Jeff: But to be fair, a strawberry cervix and frothy vagianl discharge together have a specificity of 99% for trich, which is really not bad. Nachi: While many EDs sadly aren’t blessed with a wet mount, the wet mount has the advantage of being simple, convenient, and generally low cost. Jeff: While all of that is true regarding the wet mount, it’s no longer first line, again with NAAT being preferred, as it’s highly sensitive, approaching 100%. Nachi: And for those of us who don’t have access to NAAT, there are also antigen-detecting tests which don’t perform quite as well, but they are much more sensitive than the traditional wet mount. Jeff: Treatment for trichomoniasis is with oral metronidazole, 2g in a single oral dose a or 500 mg twice a day for 7 days. Alternatively, the more expensive tinidazole, 2g for 1 dose, is actually superior according to the most recent evidence. Nachi: For pregnant patients, trichomoniasis is unfortunately associated with premature delivery and premature rupture of membranes, with no improvement following treatment. Still, patients should be tested and treated, preferentially with metronidazole, to relieve symptoms and prevent partner spread. Jeff: We have two more special populations to discuss in this month’s issue - those in correctional facilities and sexual partner treatment. If you are lucky enough to be involved in treating those in correctional facilities, keep in mind that rates of gonorrhea, chlamydia, syphilis, and trichomoniasis are higher in persons in both juvenile and adult detention facilities than the general public. Nachi: In general for patients in correctional facilities, maintain a lower threshold for just about everything. This is just an at-risk population. Jeff: Let’s move on to sexual partners, and expedited partner therapy or EPT. Nachi: Once you’ve diagnosed a patient with an STD, you can also provide a prescription or medication to the patient to give to their partner or partners. Jeff: This practice is critically important to stop partners from unknowingly spreading the STD further which is a real problem. Unless prohibited by law, emergency clinicians should routinely offer EPT to patients with chlamydia, gonorrhea, or trichomoniasis. To see your states’ current status, the CDC maintains a list of the status in all 50 states. Nachi: In terms of specific partner therapies, for chlamydia, EPT can be accomplished with a single 1g dose of azithromycin or doxycyclin 100 mg bid for 7 days. Consider concurrent treatment for gonococcal infection also. Jeff: For Gonorrhea, EPT includes a single oral dose of 400 mg of cefixime and a 1g oral dose of azithromycin. Nachi: For EPT for syphilis, unfortunately the partner has to present to the ED for a single IM injection of penicillin G. While this does place a burden on the partner, it opens up an opportunity for additional serologic testing and possibly treatment of his or her partners as well. Jeff: Routine EPT for those with BV is not recommend as the data shows that partner treatment does not affect rates of relapse or recurrence. Nachi: For genital herpes, you should counsel patients and their partners that they should abstain from sexual activities when there are lesions or prodromal symptoms. Make sure to refer partners for evaluation as well. Jeff: Since there isn’t much data on HPV partner notification, for now, encourage patients to be open with their partners so they may seek treatment as well. Nachi: And lastly, for Trichomoniasis, EPT includes 2 g of metronidazole or 500 mg BID for 7 days or that single 2g dose of tinidazole. Jeff: In general, it is always better to have the partner present to a physician for diagnosis and treatment, but EPT is an option when that seems unlikely or impossible. Nachi: Also, when possible be sure to inquire about drug allergies and provide some guidelines on ER presentation for allergic reactions. Jeff: So that wraps up EPT. Let’s discuss disposition. Though most will end up going home, a few may require IV medications, such as those with severe HSV, disseminated gonococcus, and neurosyphilis. Nachi: Admission should also be strongly considered in those who are pregnant or with concern for complications. Those with severe nausea, vomiting, high fever, the inability to tolerate oral antibiotics, and those failing oral antibiotics should also be considered for admission. Jeff: But if your patient doesn’t meet those criteria, as most will not, and they are headed home, stress the importance of follow up. Especially for those with gonorrhea and chlamydia, for whom a test of cure after completion of their medication is recommended. This is even more important for pregnant women. Nachi: Chlamydia, gonorrhea, HIV, and syphilis are among the many infectious diseases that require mandatory reporting. Definitely familiarize yourself with your states’ reporting laws, as most of these patients will be headed home and you’ll want to make sure you don’t miss your chance to prevent further spread. Jeff: Perfect, so that’s it for this month’s issue. Let’s close out with some high yield points and clinical pearls. Nachi: STDs are under recognized by patients and healthcare professionals. They can often present with minimal or no symptoms and are passed unknowingly to partners. Jeff: STD’s can have devastating effects during pregnancy on the fetus. Treat these patients aggressively in the ER. Nachi: The rising rate of STD’s continues to be an economic burden on the U.S. healthcare system. Jeff: Patients can present with multiple STD’s concurrently. Avoid premature diagnostic closure and consider multiple simultaneous processes. Nachi: Urinary tract infections and STD’s can present similarly. Be sure to do a pelvic exam to avoid misdiagnosis. For the exam, always have a chaperone present. Jeff: Acute unilateral epididymitis is most commonly a result of chlamydia in men under the age of 35. Nachi: Chlamydia is the most common bacterial STD. The diagnostic test of choice is nucleic acid amplification testing (NAAT). Treat with azithromycin or doxycycline. Jeff: Gonorrhea is the second most common STD. The diagnostic test of choice here is again NAAT. Treat with ceftriaxone and azithromycin. Nachi: Gonorrhea can lead to disseminated infection such as purulent arthritis, tenosynovitis, dermatitis, polyarthralgias, endocarditis, meningitis, and osteomyelitis. Jeff: Syphilis has a wide variety of presentations over three stages. For concern of early syphilis, send RPR or VDRL for nontreponemal testing as well as an FTA-ABS or TP-PA for treponemal testing. Nachi: Tertiary syphilis can present with gummatous lesions or aortic disease many years after the primary syphilis infection. Jeff: At any stage of syphilis, the central nervous system can become infected, leading to neurosyphilis. Nachi: Bacterial vaginosis presents with a white, frothy, malodorous vaginal discharge. Treat with metronidazole. Jeff: Genital herpes is caused by HSV-1 or HSV-2. Diagnosis can often be made clinically. If sending a sample for testing, be aware that viral shedding is intermittent, so you may have a falsely negative result. Antivirals can help prevent or shorten outbreaks and decrease transmission. Nachi: Lymphogranuloma Venereum presents with small, painless papules, nodules, or ulcers. Groove sign is present in only 15%-20% of cases. Jeff: Consider Fitz-Hugh-Curtis syndrome in your differential for a sexually active patient with right upper quadrant pain. Nachi: Offer expedited partner therapy to all patients with STD’s to prevent further spread Jeff: So that wraps up Episode 27 - STDs in the ED! Incredibly high yield topic with lots of pearls.

  Jeff: Welcome back to Emplify, the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum, and I’m back with my co-host, Nachi Gupta. This month, we’re talking about a topic… Nachi: … woah wait, slow down for a minute, before we begin this month’s episode – we should take a quick pause to wish all of our listeners a happy new year! Thanks for your regular listenership and feedback. Jeff: And we’re actually hitting the two year mark since we started this podcast. At 25 episodes now, this is sort of our silver anniversary. Nachi: We have covered a ton of topics in emergency medicine so far, and we are looking forward to reviewing a lot more evidence based medicine with you all going forward. Jeff: With that, let’s get into the first episode of 2019 – the topic this month is first trimester pregnancy emergencies: recognition and management. Nachi: This month’s issue was authored by Dr. Ryan Pedigo, you may remember him from the June 2017 episode on dental emergencies, though he is perhaps better known as the director of undergraduate medical education at Harbor-UCLA Medical center. In addition, this issue was peer reviewed by Dr. Jennifer Beck-Esmay, assistant residency director at Mount Sinai St. Luke’s, and Dr. Taku Taira, the associate director of undergraduate medical education and associate clerkship director at LA County and USC department of Emergency Medicine. Jeff: For this review, Dr. Pedigo had to review a large body of literature, including thousands of articles, guidelines from the American college of obstetricians and gynecologists or ACOG, evidence based Practice bulletins, ACOG committee opinions, guidelines from the American college of radiology, the infectious diseases society of America, clinical policies from the American college of emergency physicians, and finally a series of reviews in the Cochrane database. Nachi: There is a wealth of literature on this topic and Dr. Pedigo comments that the relevant literature is overall “very good.” This may be the first article in many months for which there is an overall very good quality of literature. Jeff: It’s great to know that there is good literature on this topic. It’s incredibly important as we are not dealing with a single life here, as we usually do... we are quite literally dealing with potentially two lives as the fetus moves towards viability. With opportunities to improve outcomes for both the fetus and the mother, I’m confident that this episode will be worth your time. Nachi: Oh, and speaking of being worth your time…. Don’t forget that if you’re listening to this episode, you can claim your CME credit. Remember, the indicates an answer to one of the CME questions so make sure to keep the issue handy. Jeff: Let’s get started with some background. First trimester emergencies are not terribly uncommon in pregnancy. One study reported 85% experience nausea and vomiting. Luckily only 3% of these progressed to hyperemesis gravidarum. In addition, somewhere between 7-27% experience vaginal bleeding or miscarriage. Only 2% of these will be afflicted with an ectopic pregnancy. Overall, the maternal death rate is about 17 per 100,000 with huge racial-ethnic disparities. Nachi: And vaginal bleeding in pregnancy occurs in nearly 25% of patients. Weeks 4-8 represent the peak time for this. The heavier the bleeding, the higher the risk of miscarriage. Jeff: Miscarriage rates vary widely based on age, with an overall rate of 7-27%. This rises to nearly 40% risk in those over 40. And nearly half of miscarriages are due to fetal chromosomal abnormalities. Nachi: For patient who have a threatened miscarriage in the first trimester, there is a 2-fold increased risk of subsequent maternal and fetal adverse outcomes. Jeff: So key points here, since I think the wording and information you choose to share with often scared and worried women is important – nearly 25% of women experience bleeding in their first trimester. Not all of these will go on to miscarriages, though the risk does increase with maternal age. And of those that miscarry, nearly 50% were due to fetal chromosomal abnormalities. Nachi: So can we prevent a miscarriage, once the patient is bleeding…? Jeff: Short answer, no, longer answer, we’ll get to treatment in a few minutes. For now, let’s continue outlining the various first trimester emergencies. Next up, ectopic pregnancy… Nachi: An ectopic pregnancy is implantation of a fertilized ovum outside of the endometrial cavity. This occurs in up to 2% of pregnancies. About 98% occur in the fallopian tube. Risk factors for an ectopic pregnancy include salpingitis, history of STDs, history of PID, a prior ectopic, and smoking. Jeff: Interestingly, with respect to smoking, there is a dose-relationship between smoking and ectopic pregnancies. Simple advice here: don’t smoke if you are pregnant or trying to get pregnant. Nachi: Pretty sound advice. In addition, though an IUD is not a risk factor for an ectopic pregnancy, if you do become pregnant while you have in IUD in place, over half of these may end up being ectopic. Jeff: It’s also worth mentioning a more obscure related disease pathology here – the heterotopic pregnancy -- one in which there is an IUP and an ectopic pregnancy simultaneously. Nachi: Nausea and vomiting, though not as scary as miscarriages or an ectopic pregnancy, represent a fairly common pathophysiologic response in the first trimester -- with the vast majority of women experiencing nausea and vomiting. And as we mentioned earlier, only 3% of these progress to hyperemesis gravidarum. Jeff: And while nausea and vomiting clearly sucks, they seem to actually be protective of pregnancy loss, with a hazard ratio of 0.2. Nachi: Although this may be protective of pregnancy loss, nausea and vomiting can really decrease the quality of life in pregnancy -- with one study showing that about 25% of women with severe nausea and vomiting had actually considered pregnancy termination. 75% of those women also stated they would not want to get pregnant again because of these symptoms. Jeff: So certainly a big issue.. Two other common first trimester emergency are asymptomatic bacteriuria and UTIs. In pregnant patients, due to anatomical and physiologic changes in the GU tract – such as hydroureteronephrosis that occurs by the 7th week and urinary stasis due to bladder displacement – asymptomatic bacteriuria is a risk factor for developing pyelonephritis. Nachi: And pregnant women are, of course, still susceptible to the normal ailments of young adult women like acute appendicitis, which is the most common surgical problem in pregnancy. Jeff: Interestingly, based on epidemiologic data, pregnant women are less likely to have appendicitis than age-matched non-pregnant woman. I’d like to think that there is a good pathophysiologic explanation there, but I don’t have a clue as to why that might be. Nachi: Additionally, the RLQ is the the most common location of pain from appendicitis in pregnancies of all gestational ages. Peritonitis is actually slightly more common in pregnant patients, with an odds ratio of 1.3. Jeff: Alright, so I think we can put that intro behind us and move on to the differential. Nachi: When considering the differential for abdominal pain or vaginal bleeding in the first trimester, you have to think broadly. Among gynecologic causes, you should consider miscarriage, septic abortion, ectopic pregnancy, corpus luteum cyst, ovarian torsion, vaginal or cervical lacerations, and PID. For non-gynecologic causes, you should also consider appendicitis, cholecystitis, hepatitis, and pyelonephritis. Jeff: In the middle of that laundry list you mentioned there is one pathology which I think merits special attention - ovarian torsion. Don’t forget that patients undergoing ovarian stimulation as part of assisted reproductive technology are at a particularly increased risk due to the larger size of the ovaries. Nachi: Great point. Up next we have prehospital care... Jeff: Always a great section. First, prehospital providers should attempt to elicit an ob history. Including the number of weeks’ gestation, LMP, whether an IUP has already been confirmed, prior hx of ectopic, and amount of vaginal bleeding. In addition, providers should consider an early destination consult both to select the correct destination and to begin the process of mobilizing resources early in those patients who really need them, such as those with hemodynamic instability. Nachi: As with most pathologies, the more time you give the receiving facility to prepare, the better the care will be, especially the early care, which is critical. Jeff: Now that the patient has arrived in the ED we can begin our H&P. Nachi: When eliciting the patient’s obstetrical history, it’s common to use the G’s and Ps. This can be further annotated using the 4-digit TPAL method, that’s term-preterm-abortus-living. Jeff: With respect to vaginal bleeding, make sure to ask about the number of pads and how this relates to the woman’s normal number of pads. In addition, make sure to ask about vaginal discharge or even about the passage of tissue. Nachi: You will also need to elicit whether or not the patient has a history of a prior ectopic pregnancies as this is a major risk for future ectopics. And ask about previous sexually transmitted infections also. Jeff: And, of course, make sure to elicit a history of assisted reproductive technology, as this increases the risk of a heterotopic pregnancy. Nachi: Let’s move on to the physical. While you are certainly going to perform your standard focused physical exam, just as you would for any non-pregnant woman - what does the evidence say about the pelvic exam? I know this is a HOTLY debated topic among EM Docs. Jeff: Oh it certainly is. Dr. Pedigo takes a safe, but fair approach, noting, “A pelvic exam should always be performed if the emergency clinician suspects that it would change management, such as identifying the source of bleeding, or identifying an STD or PID.” However, it is noteworthy that the only real study he cites on this topic, an RCT of pelvic vs no pelvic in those with a confirmed IUP and first trimester bleeding, found no difference between the two groups. Obviously, the pelvic group reported more discomfort. Nachi: You did leave out one important fact about the study enrollment - they only enrolled about 200 of 700 intended patients. Jeff: Oh true, so a possibly underpowered study, but it’s all we’ve got on the topic. I think I’m still going to do pelvic exams, but it’s something to think about. Nachi: Moving on, all unstable patients with vaginal bleeding and no IUP should be assumed to have an ectopic until proven otherwise. Ruptured ectopics can manifest with a number of physical exam findings including abdominal tenderness, with peritoneal signs, or even with bradycardia due to vagal stimulation in the peritoneum. Jeff: Perhaps most importantly, no history or physical alone can rule in or out an ectopic pregnancy, for that you’ll need testing and imaging or operative findings. Nachi: And that’s a perfect segue into our next section - diagnostic studies. Jeff: Up first is the urine pregnancy test. A UPT should be obtained in all women of reproductive age with abdominal pain or vaginal bleeding, and likely other complaints too, though we’re not focusing on them now. Nachi: The UPT is a great test, with nearly 100% sensitivity, even in the setting of very dilute urine. False positives are certainly plausible, with likely culprits being recent pregnancy loss, exogenous HCG, or malignancy. Jeff: And not only is the sensitivity great, but it’s usually positive just 6-8 days after fertilization. Nachi: While the UPT is fairly straight forward, let’s talk about the next few tests in the context of specific disease entities, as I think that may make things a bit simpler -- starting with bHCG in the context of miscarriage and ectopic pregnancy. Jeff: Great starting point since there is certainly a lot of debate about the discriminatory zone. So to get us all on the same page, the discriminatory zone is the b-HCG at which an IUP is expected to be seen on ultrasound. Generally 1500 is used as the cutoff. This corresponds nicely to a 2013 retrospective study demonstrating a bHCG threshold for the fetal pole to be just below 1400. Nachi: However, to actually catch 99% of gestational sacs, yolk sacs, and fetal poles, one would need cutoffs of around 3500, 18000, and 48,000 respectively -- much higher. Jeff: For this reason, if you want to use a discriminatory zone, ACOG recommends a conservatively high 3,500, as a cutoff. Nachi: I think that’s an understated point in this article, the classic teaching of a 1500 discriminatory zone cutoff is likely too low. Jeff: Right, which is why I think many ED physicians practice under the mantra that it’s an ectopic until proven otherwise. Nachi: Certainly a safe approach. Jeff: Along those lines, lack of an IUP with a bHCG above whatever discriminatory zone you are using does not diagnose an ectopic, it merely suggests a non-viable pregnancy of undetermined location. Nachi: And if you don’t identify an IUP, serial bHCGs can be really helpful. As a rule of thumb -- in cases of a viable IUP -- b-HCG typically doubles within 48 hours and at a minimum should rise 53%. Jeff: In perhaps one of the most concerning things I’ve read in awhile, one study showed that ⅓ of patients with an ectopic had a bCHG rise of 53% in 48h and 20% of patients with ectopics had a rate of decline typical to that of a miscarriage. Nachi: Definitely concerning, but this is all the more reason you need to employ our favorite imaging modality… the ultrasound. Jeff: All patients with a positive pregnancy test and vaginal bleeding should receive an ultrasound performed by either an emergency physician or by radiology. Combined with a pelvic exam, this can give you almost all the data necessary to make the diagnosis, even if you don’t find an IUP. Nachi: And yes, there is good data to support ED ultrasound for this indication, both transabdominal and transvaginal, assuming the emergency physician is credentialed to do so. A 2010 Meta-Analysis found a NPV of 99.96% when an er doc identified an IUP on bedside ultrasound. So keep doing your bedside scans with confidence. Jeff: Before we move on to other diagnostic tests, let’s discuss table 2 on page 7 to refresh on key findings of each of the different types of miscarriage. For a threatened abortion, the os would be closed with an IUP seen on ultrasound. For a completed abortion, you would expect a closed OS with no IUP on ultrasound with a previously documented IUP. Patients may or may not note the passage of products of conception. Nachi: A missed abortion presents with a closed os and a nonviable fetus on ultrasound. Findings such as a crown-rump length of 7 mm or greater without cardiac motion is one of several criteria to support this diagnosis. Jeff: An inevitable abortion presents with an open OS and an IUP on ultrasound. Along similar lines, an incomplete abortion presents with an open OS and partially expelled products on ultrasound. Nachi: And lastly, we have the septic abortion, which is sort of in a category of its own. A septic abortion presents with either an open or closed OS with essentially any finding on ultrasound in the setting of an intrauterine infection and a fever. Jeff: I’ve only seen this two times, and both women were incredibly sick upon presentation. Such a sad situation. Nachi: For sure. Before we move on to other tests, one quick note on the topic of heterotopic pregnancies: because the risk in the general population is so incredibly low, the finding of an IUP essentially rules out an ectopic pregnancy assuming the patient hasn’t been using assisted reproductive technology. In those that are using assisted reproductive technology, the risk rises to 1 in 100, so finding an IUP, in this case, doesn’t necessarily rule out a heterotopic pregnancy. Jeff: Let’s move on to diagnostic studies for patients with nausea and vomiting. Typically, no studies are indicated beyond whatever you would order to rule out other serious pathology. Checking electrolytes and repleting them should be considered in those with severe symptoms. Nachi: For those with symptoms suggestive of a UTI, a urinalysis and culture should be sent. Even if the urinalysis is negative, the culture may still have growth. Treat asymptomatic bacteriuria and allow the culture growth to guide changes in antibiotic selection. Jeff: It’s worth noting, however, that a 2016 systematic review found no reliable evidence supporting routine screening for asymptomatic bacteriuria, so send a urinalysis and culture only if there is suspicion for a UTI. Nachi: For those with concern for appendicitis, while ultrasound is a viable imaging modality, MRI is gaining favor. Both are specific tests, however one study found US to visualize the appendix only 7% of the time in pregnant patients. Jeff: Even more convincingly, one 2016 meta analysis found MRI to have a sensitivity and specificity of 94 and 97% respectively suggesting that a noncontrast MRI should be the first line imaging modality for potential appendicitis. Nachi: You kind of snuck it in there, but this is specifically a non-contrast MRI. Whereas a review of over a million pregnancies found no associated fetal risk with routine non-contrast MRI, gadolinium-enhanced MRI has been associated with increased rates of stillbirth, neonatal death, and rheumatologic and inflammatory skin conditions. Jeff: CT is also worth mentioning since MRI and even ultrasound may not be available to all of our listeners. If you do find yourself in such a predicament, or you have an inconclusive US without MRI available, a CT scan may be warranted as the delay in diagnosis and subsequent peritonitis has been found to increase the risk of preterm birth 4-fold. Nachi: Right, and a single dose of ionizing radiation actually does not exceed the threshold dose for fetal harm. Jeff: Let’s talk about the Rh status and prevention of alloimmunization. While there are no well-designed studies demonstrating benefit to administering anti-D immune globulin to Rh negative patients, ACOG guidelines state “ whether to administer anti-D immune globulin to a patient with threatened pregnancy loss and a live embryo or fetus at or before 12 weeks of gestation is controversial, and no evidence-based recommendation can be made.” Nachi: Unfortunately, that’s not particularly helpful for us. But if you are going to treat an unsensitized Rh negative female with vaginal bleeding while pregnant with Rh-immune globulin, they should receive 50 mcg IM of Rh-immune globulin within 72 hours, or the 300 mcg dose if that is all that is available. It’s also reasonable to administer Rh(d)-immune globulin to any pregnant female with significant abdominal trauma. Jeff: Moving on to the treatment for miscarriages - sadly there isn’t much to offer here. For those with threatened abortions, the vast majority will go on to a normal pregnancy. Bedrest had been recommended in the past, but there is little data to support this practice. Nachi: For incomplete miscarriages, if visible, products should be removed and you should consider sending those products to pathology for analysis, especially if the patient has had recurrent miscarriages. Jeff: For those with a missed abortion or incomplete miscarriages, options include expectant management, medical management or surgical management, all in consultation with an obstetrician. It’s noteworthy that a 2012 Cochrane review failed to find clear superiority for one strategy over another. This result was for the most part re-confirmed in a 2017 cochrane review. The latter study did find, however, that surgical management in the stable patient resulted in lower rates of incomplete miscarriage, bleeding, and need for transfusion. Nachi: For expectant management, 50-80% will complete their miscarriage within 7-10 days. Jeff: For those choosing medical management, typically with 800 mcg of intravaginal misoprostol, one study found this to be 91% effective in 7 days. This approach is preferred in low-resource settings. Nachi: And lastly, remember that all of these options are only options for stable patients. Surgical management is mandatory for patients with significant hemorrhage or hemodynamic instability. Jeff: Since the best evidence we have doesn’t suggest a crystal clear answer, you should rely on the patient’s own preferences and a discussion with their obstetrician. For this reason and due to the inherent difficulty of losing a pregnancy, having good communication is paramount. Nachi: Expert consensus recommends 6 key aspects of appropriate communication in such a setting: 1 assess the meaning of the pregnancy loss, give the news in a culturally competent and supportive manner, inform the family that grief is to be expected and give them permission to grieve in their own way, learn to be comfortable sharing the products of conception should the woman wish to see them, 5. provide support for whatever path she chooses, 6. and provide resources for grief counselors and support groups. Jeff: All great advice. The next treatment to discuss is that for pregnancy of an unknown location and ectopic pregnancies. Nachi: All unstable patients or those with suspected or proven ectopic or heterotopic pregnancies should be immediately resuscitated and taken for surgical intervention. Jeff: For those that are stable, with normal vitals, and no ultrasound evidence of a ruptured ectopic, with no IUP on ultrasound, -- that is, those with a pregnancy of unknown location, they should be discharged with follow up in 48 hours for repeat betaHCG and ultrasound. Nachi: And while many patients only need a single additional beta check, some may need repeat 48 hour exams until a diagnosis is established. Jeff: For those that are stable with a confirmed tubal ectopic, you again have a variety of treatment options, none being clearly superior. Nachi: Treatment options here include IM methotrexate, or a salpingostomy or salpingectomy. Jeff: Do note, however, that a bHCG over 5000, cardiac activity on US, and inability to follow up are all relative contraindications to methotrexate treatment. Absolute contraindications to methotrexate include cytopenia, active pulmonary disease, active peptic ulcer disease, hepatic or renal dysfunction, and breastfeeding. Nachi: Such decisions, should, of course, be made in conjunction with the obstetrician. Jeff: Always good to make a plan with the ob. Moving on to the treatment of nausea and vomiting in pregnancy, ACOG recommends pyridoxine, 10-25 mg orally q8-q6 with or without doxylamine 12.5 mg PO BID or TID. This is a level A recommendation as first-line treatment! Nachi: In addition, ACOG also recommends nonpharmacologic options such as acupressure at the P6 point on the wrist with a wrist band. Ginger is another nonpharmacologic intervention that has been shown to be efficacious - 250 mg by mouth 4 times a day. Jeff: So building an algorithm, step one would be to consider ginger and pressure at the P6 point. Step two would be pyridoxine and doxylamine. If all of these measures fail, step three would be IV medication - with 10 mg IV of metoclopramide being the agent of choice. Nachi: By the way, ondansetron carries a very small risk of fetal cardiac abnormalities, so the other options are of course preferred. Jeff: In terms of fluid choice for the actively vomiting first trimester woman, both D5NS and NS are appropriate choices, with slightly decreased nausea in the group receiving D5NS in one randomized trial of pregnant patients admitted for vomiting to an overnight observation unit. Nachi: Up next for treatment we have asymptomatic bacteriuria. As we stated previously, asymptomatic bacteriuria should be treated. This is due to anatomical and physiologic changes which put these women at higher risk than non-pregnant women. Jeff: And this recommendation comes from the 2005 IDSA guidelines. In one trial, treatment of those with asymptomatic bacteriuria with nitrofurantoin reduced the incidence of developing pyelonephritis from 2.4% to 0.6%. Nachi: And this trial specifically examined the utility of nitrofurantoin. Per a 2010 and 2011 Cochrane review, there is not evidence to recommend one antibiotic over another, so let your local antibiograms guide your treatment. Jeff: In general, amoxicillin or cephalexin for a full 7 day course could also be perfectly appropriate. Nachi: A 2017 ACOG Committee Opinion analyzed nitrofurantoin and sulfonamide antibiotics for association with birth defects. Although safe in the second and third trimester, they recommend use in the first trimester -- only when no other suitable alternatives are available. Jeff: For those, who unfortunately do go on to develop pyelo, 1g IV ceftriaxone should be your drug of choice. Interestingly, groups have examined outpatient care with 2 days of daily IM ceftriaxone vs inpatient IV antibiotic therapy and they found that there may be a higher than acceptable risk in the outpatient setting as several required eventual admission and one developed septic shock in their relatively small trial. Nachi: And the last treatment to discuss is for pregnant patient with acute appendicitis. Despite a potential shift in the standard of care for non pregnant patients towards antibiotics-only as the initial treatment, due to the increased risk of serious complications for pregnant women with an acute appy, the best current evidence supports a surgical pathway. Jeff: Perfect, so that wraps up treatment. We have a few special considerations this month, the first of which revolves around ionizing radiation. Ideally, one should limit the amount of ionizing radiation exposure during pregnancy, however avoiding it all together may lead to missed or delayed diagnoses and subsequently worse outcomes. Nachi: It’s worth noting that the American College of Radiology actually lists several radiographs that are such low exposure that checking a urine pregnancy test isn’t even necessary. These include any imaging of the head and neck, extremity CT, and chest x-ray. Jeff: Of course, an abdomen and pelvis CT carries the greatest potential risk. However, if necessary, it’s certainly appropriate as long as there is a documented discussion of the risk and benefits with the patient. Nachi: And regarding iodinated contrast for CT -- it appears to present no known harm to the fetus, but this is based on limited data. ACOG recommends using contrast only if “absolutely required”. Jeff: Right and that’s for iodinated contrasts. Gadolinium should always be avoided. Let me repeat that Gadolinium should always be avoided Nachi: Let’s also briefly touch on a controversial topic -- that of using qualitative urine point of care tests with blood instead of urine. In short, some devices are fda-approved for serum, but not whole blood. Clinicians really just need to know the equipment and characteristics at their own site. It is worth noting that there have been studies on determining whether time can be saved by using point of care blood testing instead of urine for the patient who is unable to provide a prompt sample. Initial study conclusions are promising. But again, you need to know the characteristics of the test at your ER. Jeff: One more controversy in this issue is that of expectant management for ectopic pregnancy. A 2015 randomized trial found similar outcomes for IM methotrexate compared to placebo for tubal ectopics. Inclusion criteria included hemodynamic stability, initial b hcg < 2000, declining b hcg titers 48 hours prior to treatment, and visible tubal pregnancy on trans vaginal ultrasound. Another 2017 multicenter randomized trial found similar results. Nachi: But of course all of these decisions should be made in conjunction with your obstetrician colleagues. Jeff: Let’s move on to disposition. HDS patients who are well-appearing with a pregnancy of undetermined location should be discharged with a 48h beta hcg recheck and ultrasound. All hemodynamically unstable patients, should of course be admitted and likely taken directly to the OR. Nachi: Also, all pregnant patients with acute pyelonephritis require admission. Outpatient tx could be considered in consultation with ob. Jeff: Patient with hyperemesis gravidarum who do not improve despite treatment in the ED should also be admitted. Nachi: Before we close out the episode, let’s go over some key points and clinical pearls... J Overall, roughly 25% of pregnant women will experience vaginal bleeding and 7-27% of pregnant women will experience a miscarriage 2. Becoming pregnant with an IUD significantly raises the risk of ectopic pregnancy. 3. Ovarian stimulation as part of assisted reproductive technology places pregnant women at increased risk of ovarian torsion. 4. Due to anatomical and physiologic changes in the genitourinary tract, asymptomatic bacteriuria places pregnant women at higher risk for pyelonephritis. As such, treat asymptomatic bacteriuria according to local antibiograms. 5. A pelvic exam in the setting of first trimester bleeding is only warranted if you suspect it might change management. 6. Unstable patients with vaginal bleeding and no IUP should be assumed to have an ectopic pregnancy until proven otherwise. 7. If you are to use a discriminatory zone, ACOG recommends a beta-hCG cutoff of 3500. 8. The beta-hCG typically doubles within 48 hours during the first trimester. It should definitely rise by a minimum of 53%. 9. For patients using assisted reproductive technology, the risk of heterotopic pregnancy becomes much higher. Finding an IUP does not necessarily rule out a heterotopic pregnancy. N. Send a urine culture for patients complaining of UTI symptoms even if the urinalysis is negative. J. The most common surgical problem in pregnancy is appendicitis. N, If MRI is not available and ultrasound was inconclusive, CT may be warranted for assessing appendicitis. The risk of missing or delaying the diagnosis may outweigh the risk of radiation. J. ACOG recommends using iodinated contrast only if absolutely required. N. For stable patients with a pregnancy of unknown location, plan for discharge with follow up in 48 hours for a repeat beta-hCG and ultrasound. J For nausea and vomiting in pregnancy, try nonpharmacologic treatments like acupressure at the P6 point on the wrist or ginger supplementation. First line pharmacologic treatment is pyridoxine. Doxylamine can be added. Ondansetron may increase risk of fetal cardiac abnormalities N So that wraps up episode 24 - First Trimester Pregnancy Emergencies: Recognition and Management.

  Jeff: Welcome back to Emplify, the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum, and I’m back with my co-host, Nachi Gupta. This month, we’re talking about a topic that is ripe for review this time of year. We’re talking Influenza… Diagnosis and Management. Nachi: Very appropriate as the cold is settling in here in NYC and we’re already starting to see more cases of influenza. Remember that as you listen through the episode, the means we’re about to cover one of the CME questions for those of you listening at home with the print issue handy. Jeff: This month’s issue was authored by Dr. Al Giwa of the Icahn School of Medicine at Mount Sinai, Dr. Chinwe Ogedegbe of the Seton Hall School of Medicine, and Dr. Charles Murphy of Metrowest Medical Center. Nachi: And this issue was peer reviewed by Dr. Michael Abraham of the University of Maryland School of Medicine and by Dr. Dan Egan, Vice Chair of Education of the Department of Emergency Medicine at Columbia University. Jeff: The information contained in this article comes from articles found on pubmed, the cochrane database, center for disease control, and the world health organization. I’d say that’s a pretty reputable group of sources. Additionally, guidelines were reviewed from the american college of emergency physicians, infectious disease society of america, and the american academy of pediatrics. Nachi: Some brief history here to get us started -- did you know that in 1918/1919, during the influenza pandemic, about one third of the world’s population was infected with influenza? Jeff: That’s wild. How do they even know that? Nachi: Not sure, but also worth noting -- an estimated 50 million people died during that pandemic. Jeff: Clearly a deadly disease. Sadly, that wasn’t the last major outbreak… fifty years later the 1968 hong kong influenza pandemic, H3N2, took between 1 and 4 million lives. Nachi: And just last year we saw the 2017-2018 influenza epidemic with record-breaking ED visits. This was the deadliest season since 1976 with at least 80,000 deaths. Jeff: The reason for this is multifactorial. The combination of particularly mutagenic strains causing low vaccine effectiveness, along with decreased production of IV fluids and antiviral medication because of the hurricane, all played a role in last winter’s disastrous epidemic. Nachi: Overall we’re looking at a rise in influenza related deaths with over 30,000 deaths annually in the US attributed to influenza in recent years. The ED plays a key role in outbreaks, since containment relies on early and rapid identification and treatment. Jeff: In addition to the mortality you just cited, influenza also causes a tremendous strain on society. The CDC estimates that epidemics cost 10 billion dollars per year. They also estimate that an epidemic is responsible for 3 million hospitalized days and 31 million outpatient visits each year. Nachi: It is thought that up to 20% of the US population has been infected with influenza in the winter months, disproportionately hitting the young and elderly. Deaths from influenza have been increasing over the last 20 years, likely in part due to a growing elderly population. Jeff: And naturally, the deaths that we see from influenza also disproportionately affect the elderly, with up to 90% occurring in those 65 or older. Nachi: Though most of our listeners probably know the difference between an influenza epidemic and pandemic, let’s review it anyway. When the number of cases of influenza is higher than what would be expected in a region, an epidemic is declared. When the occurrence of disease is on a worldwide spectrum, the term pandemic is used. Jeff: I think that’s enough epidemiology for now. Let’s get started with the basics of the influenza virus. Influenza is spread primarily through direct person-to-person contact via expelled respiratory secretions. It is most active in the winter months, but can be seen year-round. Nachi: The influenza virus is a spherical RNA-based virus of the orthomyxoviridae family. The RNA core is associated with a nucleoprotein antigen. Variations of this antigen have led to the the 3 primary subgroups -- influenza A, B, and C, with influenza A being the most common. Jeff: Influenza B is less frequent, but is more frequently associated with epidemics. And Influenza C is the form least likely to infect humans -- it is also milder than both influenza A or B. Nachi: But back to Influenza A - it can be further classified based on its transmembrane or surface proteins, hemagglutinin and neuraminidase - or H and N for short. There are actually 16 different H subtypes and 9 different N subtypes, but only H1, H2, H3, and N1 and N2 have caused epidemic disease. Jeff: Two terms worth learning here are antigen drift and anitgen shift. Antigen drift refers to small point mutations to the viral genes that code for H and N. Antigen shift is a much more radical change, with reassortment of viral genes. When cells are infected by 2 or more strains, a new strain can emerge after genetic reassortment. Nachi: With antigen shift, some immunity may be maintained within a population infected by a similar subtype previously. With antigen drift, there is loss of immunity from prior infection. Jeff: The appearance of new strains of influenza typically involves an animal host, like pigs, horses, or birds. This is why you might be hear a strain called “swine flu”, “equine flu”, or “avian flu”. Close proximity with these animals facilitates co-infection and genetic reassortment. Nachi: I think that’s enough basic biology for now, let’s move on to pathophysiology. When inhaled, the influenza virus initially infects the epithelium of the upper respiratory tract and alveolar cells of the lower respiratory tract. Viral replication occurs within 4 to 6 hours. Incubation is 18 to 72 hours. Viral shedding is usually complete roughly 7 days after infection, but can be longer in children and immunocompromised patients. Jeff: As part of the infectious process and response, there can be significant changes to the respiratory tract with inflammation and epithelial cell necrosis. This can lead to viral pneumonia, and occasionally secondary bacterial pneumonia. Nachi: The secondary bacterial pathogens that are most common include Staph aureus, Strep pneumoniae, and H influenzae. Jeff: Despite anything you may read on the internet, vaccines work and luckily influenza happens to be a pathogen which we can vaccinate against. As such, there are 3 methods approved by the FDA for producing influenza vaccines -- egg-based, cell-based, or recombinant influenza vaccine. Once the season’s most likely strains have been determined, the virus is introduced into the medium and allowed to replicate. The antigen is then purified and used to make an injection or nasal spray. Nachi: It isn’t easy to create vaccines for all strains. H3N2, for example, is particularly virulent, volatile, and mutagenic, which leads to poor prophylaxis against this particular subgroup. Jeff: In fact, a meta-analysis on vaccine effectiveness from 2004-2015 found that the pooled effectiveness against influenza B was 54%, against the H1N1 pandemic in 2009 was 61%, and against the H3N2 virus was 33%. Not surprisingly, H3N2 dominant seasons are currently associated with the highest rates of influenza cases, hospitalizations, and death. Nachi: Those are overall some low percentages. So should we still be getting vaccinated? The answer is certainly a resounding YES.. Despite poor protection from certain strains, vaccine effectiveness is still around 50% and prevents severe morbidity and mortality in those patients. Jeff: That’s right. The 2017-2018 vaccine was only 40% effective, but this still translates to 40% less severe cases and a subsequent decrease in hospitalizations and death. Nachi: But before we get into actual hospitalization, treatment, and preventing death, let’s talk about the differential. We’re not just focusing on influenza here, but any influenza like illness, since they can be hard to distinguish. The CDC defines “influenza-like illness” as a temperature > 100 F, plus cough or sore throat, in the absence of a known cause other than influenza. Jeff: Therefore, influenza should really be considered on the differential of any patient who presents to the ED with a fever and URI symptoms. The differential when considering influenza might also include mycoplasma pneumoniae, strep pneumoniae, adenovirus, RSV, rhinovirus, parainfluenza virus, legionella, and community acquired MRSA. Nachi: With the differential in mind, let’s move on to prehospital care. For the prehospital setting, there isn’t much surprising here. Stabilize and manage the respiratory status with all of your standard tools - oxygen for those with mild hypoxia and advanced airway maneuvers for those with respiratory distess. Jeff: Of note, EMS providers should use face masks themselves and place them on patients as well. As community paramedicine and mobile integrated health becomes more common, this is one potential area where EMS can potentially keep patients at home or help them seek treatment in alternate destinations to avoid subjecting crowded ED’s to the highly contagious influenza virus. Nachi: It’s also worth noting, that most communities have strategic plans in the event of a major influenza outbreak. Local, state, and federal protocols have been designed for effective care delivery. Jeff: Alright, so now that the EMS crew, wearing proper PPE of course, has delivered the patient, who is also wearing a mask, to the ED, we can begin our ED H&P. Don’t forget that patients present with a range of symptoms that vary by age. A typical history is 2-5 days of fever, nasal congestion, sore throat, and myalgias. You might see tachycardia, cough, dyspnea, and chills too. Nachi: Van Wormer et al conducted a prospective analysis of subjective symptoms to determine correlation with lab confirmed influenza. They found the most common symptoms were cough in 92%, fatigue in 91%, and nasal congestion in 84%, whereas sneezing was actually a negative predictor for influenza. Jeff: Sneezing, really? Can’t wait to get the Press-Gany results from the sneezing patient I discharge without testing for influenza based on their aggressive sneezes! Nachi: Aggressive sneezes…? I can’t wait to see your scale for that. Jeff: Hopefully I’ll have it in next month’s annals. In all seriousness, I’m not doing away with flu swabs just yet. In another retrospective study, Monto et al found that the best multivariate predictors were cough and fever with a positive predictive value of 79%. Nachi: Yet another study in children found that the predominant symptoms were fever in 95%, cough in 77%, and rhinitis in 78%. This study also suggested that the range of fever was higher in children and that GI symptoms like vomiting and diarrhea were more common in children than adults. Jeff: Aside from symptomatology, there are quite a few diagnostic tests to consider including viral culture, immunofluoresence, rt-pcr, and rapid antigen testing. The reliability of testing varies greatly depending on the type of test, quality of the sample, and the lab. During a true epidemic, formal testing might not be indicated as the decision to treat is based on treatment criteria like age, comorbidities, and severity of illness. Nachi: We’ll get to treatment in a few minutes, but diving a bit deeper into testing - there are 3 major categories of tests. The first detects influenza A only. The second detects either A or B, but cannot distinguish between them; and the third detects both influenza A and B and is subtype specific. The majority of rapid testing kits will distinguish between influenza A and B, but not all can distinguish between them. Fluorescent antibody testing by DFA is relatively rapid and yields results within 2 to 4 hours. Jeff: Viral culture and RT-PCR remain the gold standard, but both require more time and money, as well as a specialized lab. As a result, rapid testing modalities are recommended. Multiple studies have shown significant benefit to the usefulness of positive results on rapid testing. It’s safe to say that at a minimum, rapid testing helps decrease delays in treatment and management. Nachi: Looking a bit further into the testing characteristics, don’t forget that the positive predictive value of testing is affected by the prevalence of influenza. In periods of low influenza activity (as in the summer), a rapid test will have low PPV and high NPV. The test is more likely to yield false positive results -- up to 50% according to one study when prevalence is below 5%. Jeff: And conversely, in periods of high influenza activity, a rapid test will have higher PPV and lower NPV, and it is more likely to produce a false negative result. Nachi: In one prospective study of patients who presented with influenza-like illness during peak season, rapid testing was found to be no better than clinical judgement. During these times, it’s probably better to reserve testing for extremely ill patients in whom diagnostic closure is particularly important. And since the quality of the specimen remains important, empiric treatment of critically ill patients should still be considered. Jeff: Which is a perfect segway into our next topic - treatment, which is certainly the most interesting section of this article. To start off -- for mild to moderate disease and no underlying high risk conditions, supportive therapy is usually sufficient. Nachi: Antiviral therapy is reserved for those with a predicted severe disease course or with high risk conditions like long-standing pulmonary disease, pregnancy, immunocompromise, or even just being elderly. Jeff: Note to self, avoid being elderly. Nachi: Good luck with that. Anyway, early treatment with antivirals has been shown to reduce influenza-related complications in both children and adults. Jeff: Once you’ve decided to treat the patient, there are two primary classes of antivirals -- adamantane derivatives and neuraminidase inhibitors. Oh and then there is a new single dose oral antiviral that was just approved by the FDA… baloxavir marboxil (or xofluza), which is in a class of its own -- a polymerase endonuclease inhibitor. Nachi: The oldest class, the adamantane derivatives, includes amantadine and rimantadine. Then the newer class of neuraminidase inhibitors includes oseltamavir (which is taken by mouth), zanamavir (which is inhaled), and peramivir (which is administered by IV). Jeff: Oseltamavir is currently approved for patients of all ages. A 2015 meta analysis showed that the intention-to-treat infected population had a shorter time to alleviation of all symptoms from 123 hours to 98 hours. That’s over a day less of symptoms, not bad! There were also fewer lower respiratory tract complications requiring antibiotics and fewer admissions for any cause. Really, not bad! Nachi: Zanamavir is approved for patients 7 and older -- or for children 5 or older for disease prevention. Zanamavir has been associated with possible bronchospasm and is contraindicated in patients with reactive airway disease. Jeff: Peramivir, the newest drug in this class, is given as a single IV dose for patients with uncomplicated influenza who have been sick for 2 days or less. Peramavir is approved for patients 2 or older. This is a particularly great choice for a vomiting patient. Nachi: And as you mentioned before, just last month, the FDA approved baloxavir, a single dose antiviral. It’s effective for influenza type A or B. Note that safety and efficacy have not been established for patients less than 12 years old, weighing less than 40 kg, or pregnant or lactating patients. Jeff: Unfortunately, there has been some pretty notable antiviral resistance in the recent past, moreso with the adamantane class, but recently also with the neuraminidase inhibitors. In 2007-2008, an oseltamivir-resistant H1N1 strain emerged globally. Luckily, cross-resistance between baloxavir and the adamantanes or neuraminidase inhibitors isn’t expected, as they target different viral proteins, so this may be an answer this year, and in the future. Nachi: Let’s talk chemoprophylaxis for influenza.. Chemoprophylaxis with oseltamavir or zanamavir can be considered for patients who are at high risk for complications and were exposed to influenza in the first 2 weeks following vaccination, patients who are at high risk for complications and cannot receive the vaccination, and those who are immunocompromised. Jeff: Chemoprophylaxis is also recommended for pregnant women. For postexposure prophylaxis for pregnant women, the current recommendation is to administer oseltamivir. Nachi: We should also discuss the efficacy of treatment with antivirals. This has been a hotly debated topic, especially with regards to cost versus benefit… In a meta-analysis, using time to alleviation of symptoms as the primary endpoint, oseltamavir resulted in an efficacy of 73% (with a wide 95% CI from 33% to 89%). And this was with dose of 150mg/day in a symptomatic influenza patient. Jeff: Similarly zanamavir given at 10mg/day was 62% effective, but again with a wide 95% CI from 15% to 83%. And, of note, other studies have looked into peramivir, but have found no significant benefits other than the route of delivery. Nachi: In another 2014 study by Muthuri et al., neuraminidase inhibitors were associated with a reduction in mortality -- adjusted OR = 0.81 (with a 95% CI 0.70 to 0.93). Also when comparing late treatment with early treatment (that is, within 2 days of symptom onset), there was a reduction in mortality risk with adjusted OR 0.48 (95%CI 0.41-0.56). These associations with reduction in mortality risk were less pronounced and less significant in children. Jeff: Mortality benefit, not bad! They further found an increase in mortality hazard ratio with each day’s delay in initiation of treatment up to 5 days, when compared to treatment initiated within 2 days. Nachi: But back to the children for a second -- another review of neuraminidase inhibitors in children < 12 years old found duration of clinical symptoms was reduced by 36 hours among previously healthy children taking oseltamivir and 30 hours by children taking zanamivir. Jeff: I think that’s worth summarizing - According to this month’s author’s review of the best current evidence, use of neuraminidase inhibitors is recommended, especially if started within 2 days, for elderly patients and those with comorbidities. Nachi: Seems like there is decent data to support that conclusion. But let’s not forget that these medications all have side effects. Jeff: These drugs actually tend to be well tolerated.The most frequently noted side effect of oseltamavir is nausea and vomiting, while zanamavir is associated with diarrhea. Nachi: Amazing. Let’s talk disposition for your influenza patient. Jeff: Disposition will depend on many clinical factors, like age, respiratory status, oxygen saturation, comorbid conditions, and reliability of follow up care. Admission might be needed not only to manage the viral infection, but also expected complications. Nachi: If you’re discharging a patient, be sure to engage in shared decision making regarding risks and benefits of available treatments. Ensure outpatient follow up and discuss return to er precautions. Jeff: Also, the CDC recommends that these patients stay home for at least 24 hours after their fever has broken. Nachi: With that -- Let’s summarize the key points and clinical pearls from this month’s issue J: Even though influenza vaccine effectiveness is typically only 50%, this still translates to a decrease in influenza-related morbidity and mortality. 2. The CDC defines influenza-like illness as a temperature > 100 F with either cough or sore throat, in the absence of a known cause other than influenza. 3. When influenza is suspected in the prehospital setting, patients and providers should wear face masks to avoid spreading the virus. 4. In the emergency department, standard isolation and droplet precautions should be maintained for suspected or confirmed infections. 5. The most common symptoms of influenza in adults are cough, fatigue, nasal congestion, and fever. Sneezing is a negative predictor in adults. 6. In children, the most common presenting symptoms are fever, cough, and rhinitis. Vomiting and diarrhea is also more common in children than adults. 7. Rapid testing and identification results in decreased delays in treatment and management decisions. 8. During peak flu season, clinical judgement may be as good as rapid testing, making rapid testing less necessary. J: Rapid testing may be more beneficial in times of lower disease prevalence. 10. Empiric treatment of critically ill patients should be considered even if rapid testing is negative. J: For mild to moderate disease and no underlying high-risk conditions, supportive therapy is usually sufficient. 12.For more ill patients or those at substantial risk for complications, consider antiviral treatment. 13.Oseltamivir is approved for patients of all ages, and reduces the length of symptoms by one day. 14.When treating influenza, peramivir is an ideal agent for the vomiting patient. 15.Baloxavir is a new single-dose antiviral agent approved by the FDA in October 2018. It works in a novel way and is effective for treatment of influenza A and B. 16.Chemoprophylaxis with oseltamivir or zanamivir should be considered in patients who are immunocompromised or patients who are at elevated risk for complications and cannot receive the vaccination. 17.Consider oseltamivir as post exposure prophylaxis in pregnant women. 18.Neuraminidase inhibitors are associated with decreased duration of symptoms and complications, especially if started within 2 days of symptom onset.

When it comes to buying internet businesses, is it better to buy big or buy small? Today we are chatting with Jeff Hunt of Own Optimize. Jeff has one of the largest web business portfolios we have come across here at Quiet Light. Through close to 60 transactions, he has owned a total of nearly 500 websites. These days Jeff spends his time working on his websites and educating others on how to buy internet businesses. After a career with IBM in the services business, a move overseas led Jeff to the internet where he started a real estate website. Despite a tech background, he didn't really know anything about websites when he started out. Soon he learned that buying them was much easier than making them and started to build his portfolio. Today we talk to him all about what to focus on once a website catches your interest. Episode Highlights: Start off on the right foot at the very beginning of the process. When buying a site, what you're really looking to buy is a quality website that you can grow and automate. Jeff's range of investment is typically sites valued at $50,000 and under. Of course Jeff experienced failure, 8 out of 10 of his sites didn't make it. He admits to being guilty of chasing too many things at once. Success for Jeff has come from a combination of buying and building. Making a smaller purchase is not always for financial reasons, it can be for a new buyer to explore whether or not they even like the business. When a buyer starts small they get an opportunity to learn the transaction process. Smaller websites can carry more risk. They may not have had enough time to grow. With large sites, you still have some leverage even if you come across hard times. Owning larger sites that garner larger revenue allow buyers to afford to hire a team. Before a purchase, study the heath of the business; the historical data, the ratios, and the percentages of cost that make up the total cost. The seller should have found the key to attracting new buyers and that knowledge can be passed onto the buyer. The buyer needs to really understand the business model and hone the process that the seller has achieved. Transcription: Mark: Joe, How are you? Joe: I'm good Mark, how you doing today? Mark: Good, good! I got to talk to another member from Rhodium Weekend, which is one of those events that we talk about a lot on this podcast, to talk to Jeff Hunt. Joe: I know. Jeff Hunt's a good guy. I think he's bought four hundred (400) businesses in his lifetime. Mark: Websites, a lot of these– yeah it's about forty (40) or fifty (50) transactions that he's done, so mostly some 50,000 dollar transactions. Joe: Pause, I said four hundred (400). Am I completely wrong? Mark: No, you're not completely wrong at all. So forty (40), fifty (50) transactions but whole of about 400 to 500 websites at all. Joe: Okay, got it! Mark: Yeah, can you imagine trying to manage that many sites? Joe: Absolutely not! –trouble doing my job here at Quiet Light that is an immense amount! Mark: Yeah, I know everyone recognizes you as a slacker. Joe: (laughs) Mark: So anyways, he's bought a lot of businesses, he's bought a lot of sites and he has a lot of experience on that. Now he's teaching people, he's got the website investor– the book that he wrote. And he talks about developing systems to buy sites, successfully. And he talks a lot about some of the mistakes he made along the way. What we talk about some due diligence, but also about this ongoing question: Is it better to buy small or buy big? Now what was better for you, what's– could've helped you avoid risk more and how's that changed from the years. He's got a lot of insights into due diligence that were fascinating and honestly, the interviews I've done, I kind of wish we would flip this one around because towards the interview, absolutely, really going to miss some good topics. Joe: It's interesting that the subject of should I buy a million dollar business for– or ten– how many thousand dollar businesses always comes up. And all we can do is thought from own experience and on what other people like Jeff have done. And I think, I've had Kevin Peterson on the upsell buying portfolio SAS business as he said– I think we've quoted him that it– it takes the same amount of work to run a million dollar business as it does a hundred thousand dollar business in some cases actually takes less because it's more established. And Jeff bought forty to– 5400 smaller sites, right? Mark: That's right. And we talked about that. I do think that running-a-large of business is often less work And I wrote an article on this, years ago, We have not been blogging for almost a year now because we've been focusing on the podcast but I did right an article on this rad. I went into the data actually to take a look at: What are the average number of hours that people are working on smaller sites versus larger sites. And what is the average number of staff and how does that correlate with revenues. Really some fascinating data in there, so excited. I got to transcend you deep dive there. So all in to that much show notes, anyone wants to do some further reading. But larger sites, they're often less work. And in some ways, that's risky because there's– you have more cash flow and we talked about that. If you have a business that's– that has twenty (20) thousand dollars of revenue and you lose a key client or you lose a key-traffic source when things get cut in half, you don't have but ten (10) thousand. Joe: Absolutely! That's why, just to say it so people hear it that the– the multiple's evaluation on these jump when your discretionary earnings is up that million dollar mark, you're going to jump significantly in terms of the over-all value not– obviously because of numbers but because the multiple actually jumps too, from a– let's say from a three (3) to four (4) for an instance. Mark: Yeah and I was talking to a potential client the other day who has a business who– it's multi-million dollars of revenue but the earnings are starting to have troubles and he said, “Would anyone buy this?”. And I explained to him that if a business has millions of dollars in revenue, even if it's struggling from an earning stand point, yeah, that's going to really negatively affect the business but this is probably still is soluble. But if you have a business that makes five (5) or ten (10) thousand dollars a year in gross revenues and isn't making any money probably not going to be sold. An orgs couldn't be very difficult to sell for anything of value, so can newly certain size? It's just more flexibility on the part of a buyer. Joe: Yeah! But Jeff has a different model in system and he's buying lots of smaller one's so he's doing something very, very right. Different than your blog couple of years ago, talked about so be real interesting series got to say. Mark: Yep, let's get to it. Alright, hey Jeff! Thanks for joining me. Jeff: Hey, it's great to be here, Mark. Mark: I know we know each other from a mutual group that were both part of. And people who have listened to the podcast before will be familiar with this group, at least you've heard of it before, and that's Rhodium Weekend. You and I have attended it from the past some years, right? Jeff: Yeah, love–met a lot of fantastic people–Rhodium is a good– as you know, it's a group of people either buying, or have already bought in to operate online businesses so it's kind of really unique crowd and be part of it. Mark: Yeah, if anybody wants an introduction 0:05:43.3 let me know, I'd be more than happy and of course, Chuck will surely be able to provide that as well. Chuck Mullins who works at Quiet Light Brokerage, introduced me to Rhodium. And really– Chris had actually stopped me, but really Chuck encouraged me to go. And it's been a good investment of our time and place. It's good group and I met you there few years ago. We talked at the conference and we've seen each other at conferences since then. I think the last time we met in person was Afilias somewhat last summer. Jeff: Yeah! That's right! And I met Chuck there I think the first time at Rhodium and I formed a number of partnerships there so it's a great group of people, it's your (0:06:22.0) way around the business that were in. Mark: Alright! So, let's start getting into little bit in the– as our listeners know, we usually love our guests introduce themselves. So if you want just give, just kind of quick background on who you are and what you do, that'll be really helpful. Jeff: Okay. Well, you know, I maybe one of your older guest– I don't know but if the white here kind of gets it away a little bit, I'm in my fifty's and I'm still on the website business so… Mark: Oh, my! Jeff: Kind of funny like the bunch together that we hangout or they're a little bit younger than I am but I give them a run through their money. I actually started out in the corporate world. Probably like a lot of people buy websites and I had a crew with IBM and I was in middle managements. I had a pretty lardge organization, people who were in to service this business. So, big companies with give us their I.T. departments to run so I had development organization, infrastructure guys, and a lot. And how to buy a budget of about twenty five (25) million dollars, at that time. It's kind of funny that even though I was kind of that technical business, I didn't know anything about the internet at all. And so my first introduction to the internet was actually I started a real estate business. So I moved overseas, left IBM, moved overseas, I started this real estate business and I realized it needed a website. And so, I kind of just dove in and I learned out to do all the websites, staff and crew website for this business. And then after that , I– you know, my eyes kind of got opened to the side of the all. Starting website really hard and so I started looking at as ways to buy them. And I started buying websites and over the last ten years I actually– I've done probably fifty (50) or sixty (60) transactions and about something like three hundred (300) websites, actually probably closed to the five now but while it does ring, big groups like networks of websites that did some more functions than those kind of things. So– Then along the way, I kind of wanted to leverage some of my assets. One of my assets was just– I have been doing this for a while and you know, having my fingers and all kinds of online businesses and different business models across all the sites. And so I wrote a book called The Website Ambassador and then I've done courses on website investing and some networking like at Rhodium and other places and stuff. I really enjoyed this– I just love– I really love almost everything about online businesses. And just the lifestyle part of it but really like the analytical part of it, the marketing component and operations component. Component is just– is just low fun. So that's my story. Mark: So– I'm sorry, you said three hundred (300) and four hundred (400) websites in total? Maybe more? Jeff: Yeah! Like one of my purchases is something like two hundred and fifty (250) websites that were– I can't even read the domain names. They were German and French. And there were these affiliate websites selling Amazon FiliA products and to Amazon Germany and Amazon France. And I ran with those for couple of years some of them died off and then I sold them. Mark: Oh, okay. How in the world do you begin to even manage that many sites? Jeff: Yeah, well–you know, that's one of the many mistakes that I've made I think in the course of my website career is buying too many and chasing too many ideas that looks really interesting like– it's probably happen to you. Maybe it hasn't happen to you though like I see these things and I think “Woah! That's a very unique business modeling and that's really cool. I like to learn more about it and pick it up. Like uncharmed by those particular sites, actually those who're kind of template sites and so there was a lot of automation. There were programs that could make the same update to, ten's, twenty. Sometimes more sites at a time. So that's how we managed them. Mark: Okay, That makes a little bit more sense. Now when you say that you've been buying all these websites, we don't have to talk specific dollar amounts but who are we talking about larger sites, smaller sites, what's the range that you really been investing in. Jeff: Well I've bought in– again maybe this is something I would do differently for starting over again but most of my sites for sub- fifty thousand dollars only handful of that amount, just a lot of them as like mentioned. And I've done kind of a combination of buying and then building and typically for me the cycle's ban or buy something that I don't really know that much about like I started out with Google news approved sites and merely day so I bought a dozen different news site over time but then after a while after a year or two into that, I really understood that news business borrowed so it was very easy for me to actually create my own news websites and then go from there and I've done some more things. For example Mozilla site– so one of the reasons that we buy is because were learning something, were picking up. Were kind of learning from something that's already working. And then later on if you want to add to it by building from scratch, that's kind of a logical sequence for me. Mark: Yeah, alright, let's dive in to that topic a little bit because we get that–this question a lot from potential buyers, especially first time buyers. People that might become mean and in. They know that they want to get in to the website business or some sort of online business, they're coming from the corporate business world like you did and they might have good enough money to do a larger deal but their wonder, is that the right thing to do? And I think you might have touched a viewpoints here which might be interesting. let's talk about, specifically, let's just start with the benefits, binds small to start. You've done a lot of bind small sites and smaller sites. What were some of the big benefits that you've gotten from that and then maybe later on we can move in to some of the drawbacks from that. Jeff: Okay, yeah! That sounds great! And one of the first things that I say when I get that question by big or small is: Whatever you buy, it needs to be a good quality so it needs to be something that's very stable no matter how big or small it is. So, kind of get to your specific question, what are the benefits of buying small, first the obvious one is that you're risking less capital and for many people, that's important, especially when they don't have that experience that leads to the confidence to something bigger. So that's kind of important. And many people are running to ask me that question and it doesn't even matter what their capacity is. Some of them have a capacity in capital to buy very very large websites, multi-million dollar websites. They still don't want to do it. They want to spend five (5) thousand or twenty five (25) thousand or something like that and the reason is because it gives them the, yeah. One of the things that they think about necessarily is they don't even know what it's like to be a website owner. So it isn't just the risk of the money but they're not even sure that they'll enjoy the– be and stay which is being the owner and upper of your website. So that's one thing that binds small can do. Kind of give them a taste, what it's like. And then secondly it gives them an exercise of the transaction process. That's as you know, the transaction process is quite different from very small sites than from a large one but at least they're going through the steps of– during the evaluation, looking, evaluating, waiting, executing a transaction, setting up the accounts, perhaps hiring the team, and all of those kinds of stuff. And then some basic things that if you've never been on the website business, you've never done before like giving hosting setup and domain ownership and some of those basic things. So that's kind of the value. And the other thing is that, whereas the dynamics and management of large versus small can be quite different some of the basics in terms of the actual business models behind the sites are actually quite similar. So the content website monetized by advertising is very similar too. Whether it's big or small. Just the mechanism and process you put around that are different. So if you're unfamiliar with the business model, you can pick up some familiarity from buying a smaller site. Mark: So, you said that I think it's a key point here, and that is bind for education. And bind small for education is something that you've done quite a bit, in where you bought, you've learned in this industry a net shore, a style of online business. And I've been able to use that as an education, they will build your own as well. I talked to buyers a lot about their first purchase and an advice to buy smaller if they want to get that education set, understanding that, can you talk about that a little bit more how you've used buying small to be able to learn more about the nature, about the business style? Jeff: Yeah, that's excellent accredit in general sense education and one of the ways that we educate our self is through relationships and at working and so really, the important part when you buy a site is the relationship that you have with the seller and those have been valuable to me. I meet so many really , really instructional, educational relationships, from sellers who– and that starts with setting at the relationship– setting off at the right flow with the relationship at the very very beginning on the process. But many of the sites I bought I got really good coaching, I have relationships to this day with people that I bought sites from eight (8) years ago who were entrepreneurs, they figured something out. Most– as you know, most business is fail. Very high percentage of business is fail, off line or online. And even at higher percentage of online business is fail, been off. And I think it's just because more people try at the online business but when you have any site that's been around for a while and it's kind of built up a following and so on, is one that hasn't fail or at least not yet. And so the entrepreneurs who're able to do that and figure that out, a lot of times, they know things that you want to know from them so the key thing is actually learning what has been built, what the process is, that they use to attract customers and we'll probably talk more about that later. I hope we could. Mark: Yeah, I'll get you to talk about whatever you think will be worth talking about. I do want to talk a little bit about the differences though on bind big versus small. You mentioned in there one of the benefits to bind small is you're obviously risking what's capital. And I would completely agree with that. I mean, it's pretty obvious, if you're buying a million dollar site to buy in a ten (10) thousand dollar site, there's significantly less at stake. When I tell buyers to buy small, initially, often times I'd tell them that and say, you know, be prepared for a little bit higher risk profile. And in my experience in– feel free to disagree with this , that's in my experience buying small often comes with a little higher level of risk. I know you said you have to buy quality. What's been your experience as far as the quality businesses that you bought in this small range? Jeff: I totally agree with you and the reason that buying small carries more risk is because most smaller websites don't have the same age. They don't have the same momentum they haven't necessarily withstood the test of time. And what that really means is, in the internet business they change really fast so new competitors enter the space, there's changes in technology, changes in software, and most importantly there's changes unlike the big players like Facebook, Google and the like. And they're making policy changes and all those things, so when you buy a smaller site, in most cases, they may be successful, cause they're flying under a radar of sorts and they haven't been around long enough to see the change from desktop to mobile or from easily making Facebook ad purchases to a more competitive environment, faced to capture all those things, so as a result, the lower in sites is almost always more risky. Now obviously, you can mitigate the risk the longer you look but sometimes it takes a really long time to find the site that's– that has true stability. That's still kind of that low end so, yeah, that's right. So my experience with that, that answers a specific question is that I've failed a lot of times. Probably, my early sites that I bought, I bet you eight (8) out of ten (10) just didn't make it. Either they didn't pay for themselves and some of them might've made almost no money, most of them made some money but not nearly what I wanted and then they kind of take her off. It's hard. Mark: I found as well what larger sites having that extra cushion more discretionary earnings and more revenue, gives you a lot more ability to, not to make a mistake and absorb it. With the small site, if it's only generating twenty (20), thirty (30) thousand dollar per year, if it loses a major source of traffic, all of a sudden that twenty (20), thirty (30) thousand will go down to five (5). And now, all of a sudden you're questioning why I'm even doing this anymore. Where, you were as a few–you have a business's doing five hundred (500) thousand dollars a year and discretionary earnings and it gets hit hard. You're still probably making six (6) figures and have some leverage that are to be able to– may buy yourself out of this situation or fund what needs to be fixed Maybe place that better or so, there's a little bit of subordinate there. Workload as well, I mean– I've found in your website, in some sense, I found that with larger sites, sometimes that workload can actually be less because you can afford the higher people, where as with other site that's kind of on the edge. And I ran into this with my first company actually that I owned, I got it to a hundred twenty(220) thousand dollars in revenue and really I needed to hire people but I needed all the money. I was getting so– I couldn't really afford six months of that financial hit. What's been your experience with that? With dealing with casuals and maybe the freedoms that casuals would– of a large business would bring you? Jeff: My experience is exactly what you said where– and in fact I have websites right now where I'm forced to do things that I really shouldn't be doing, I should be spending my time thinking about the strategy, looking in for competition, time plotting on a road map, and in managing people on. And some sites is just aren't making enough money for me to hire someone to do that on month you have. So that's absolutely right, that when you get that, and you know– as I mentioned I– that there were intersections and that I've done everything where I sweep the floor myself, so I kind of gone the whole gimmick and certainly when you have a team then it really freeze you up to use your mind in a different way and that's a lot of fun if that's kind of where your skills are, what you want to do. So definitely not to big advantage of buying big. Mark: Alright, so you have done– how you told me at the beginning, I didn't worry about, how many transactions again, estimated? Jeff: Only sixty (60). Mark: Alright, that's a ton! I mean quite label with more or less than a thousand for ten years, that's with lots and lots of buyers and sellers. Sixty (60) percent is a lot. I'm going to put you on the spot and if you don't have an answer for this please just ignore it. I'm curious, what's one of the craziest thing that you can share that you've ran across in your process of buying sites? Jeff: Well. you know, I've ran across more than I– there's some crazy one's I've ran cross that I haven't bought. But there's several of them, one of them that I talk about in my book is– I found this site that– I had a hard time finding out what product is sold but it was insanely profitable like nine (9) percent profit margins but it was an E-commerce site. So it was a hard physical good and when I looked into it carefully, what they were selling was a urine. Laboratory processed urine for people who're trying to pass drug tests. And so they said, after I finally understood exactly what their product was, I understood why it was hard for me to understand, because they didn't want to like, advertise it too much that they had to do it enough to be on the safe side. Mark: There you go. One of the first clients I took on was selling poppy flowers and they were selling them for couple rearrangements, I may be naive. I had no idea that they were used for opium as well. And I had one person tell me, one buyer was like, “So are you okay with selling drugs?” I'm like, “What? What are you talking about?” Ends up, they were not, but there is people buying the poppies. At least my theory at probably buying the poppies thinking that they were buying drugs. They're probably just get stomach ache. Jeff: Alright, well, you know, that's interesting you bring that up because it's an example of one of the subtle eficlosures and we ran into this issues a lot in this business crossly, even for sites that you would think don't really have controversy around them. We ran into this kind of things. So it's one thing that buyers should be aware of. Mark: Let's (0:23:21.2) to that because you've got your course to write your book as well. Your course is at website investor.com? Is that right? Jeff: Yeah, ownoptimize.com is a good place right now. Mark: ownoptimize.com, Okay. Jeff: Yeah! Mark: We'll link to that in the troll notes so just go over to our website and look in the troll notes for the course, the online course. Let's talk about some of the lessons that you teach in this course. Obviously, we'll keep the best secrets for the courses. So– but, what are some of the things that you try and teach buyers who are taking your course? Jeff: Well, one of this– I don't want to over simplify and this may just sound too simple but one of the biggest mistakes I think that new buyers make is they don't just look at the graphs. And it's amazing what this simple graphs can tell you, the direction of the traffic, and the direction of the financial, those two simple things are really, really important. And a lot of times when you look at a graph, let's say twelve (12) month graph and it's– you can kin od tell visually that it's down or gently downwards sloping, but in truth it may actually be like twelve (12) or twenty (20) percent downward sloping and if you just extrapolate that into the future– I mean, business is going to be worth nothing in just a few years and so I think people tend to have an optimistic view when they look at numbers and sometimes they realize that their businesses that are losing money overtime and they feel like the moment that they buy this site, it's going to stop losing money, it's going to start– it's going to be flat or go up from there and there's no real reason to think that. So that's kind of really simple but that's a way that you can dismiss a lot of sites unless you have really specific knowledge about why it's going down and a very specific idea about how you can turn it around. Now we can talk about that way or two because a lot of people– that's hard to really know for sure. So then you need is just to stay away from those kinds of sites so we need to look–. So overall, key thing is you look at the graphs, if it's a stable business, you're looking for a stable business because the most important thing is– I kind of teach a risk-based methodology but for valuation and also for valuation-selection websites so for me, real core thing is you're looking for the engine for customer acquisition and you can– all kinds of sites she can evaluate, usually the successful ones. The owner, the creator, has found a way to systematically attract new clients and if it's a content site and the client is website visitor or if it's a services site, a client, whatever it is. And that process–whatever the process is, it might be toasting the Facebook every day, it might be buying Google ad words, ads, it might be just content creation regimen, it might be a product launch, philosophy on Amazon like these kinds of steps, I'd choose these kinds of products, I'd brand them in this way, I'd quadrant them in this way. And the process may be –it may not be like mind blowing in terms of what it actually is, but it might just be very consistent and perhaps complex and blast. and whatever that process is, it's that– is that engine it drives the site, that's really what you're buying because if you can get your mind around it and understand what it is that they're doing that attracts these customers consistently and then you can start envisioning how you would do that yourself and perhaps, how you would scale it, how you would tweak it to enhance it, then that's kind of the whole agree, So you want a process like that but you feel like doesn't have a hauls or gas in it, like you can see why it's working and how it's working and you get your head around that then you know the business model and then if it's historically if it's a cheap pretty solid results, consistent results, there's always going to be pivoting and changing strategies and so on but you get a model like that, that's kind of what you really want to buy, to probably grow what you're trying to buy as a buyer so that's kind of a key thing and then there's all kinds of methodology around you, valuation. We look like — there's like several dozen things you can evaluate that there's content and ownership and reasons people are selling and the financials and branding, legal aspects–all, all those kinds of things that you want to look at but the core thing is that how do they get their customers and what's the risk profile on this side. Mark: So how do you– how do you, work for– so that's really, really good advice, understanding the customer journey from beginning– from top of funnel, just awareness of the site that you're looking at down to the actual acquisition of the client. Right? How do you handle that insane environment like Amazon or were dealing with all the market places or even with– I guess with E-commerce, you do have a customer journey but have you worked much with Amazon to see how you would evaluate that? Jeff: Well, no, I don't have a lot of very specific experience with Amazon but I can tell you that– Amazon FBA is actually a very sophisticated business because there are so many elements of it and you have to do each of them quite well, actually. That's one of those cases were it's not just a simple three (3) or four (4) silver bullets and you win. It's like the people who do Amazon FBA well, do a lot of things well. They do product selection very well. Niche selection first, product selection well, then they understand the launch process like putting the right brand on their product and giving those initial reviews. And they understand the inventory process. They don't have cash problems with having generating a man and then having nothing to sell to people. Then they have to understand the operational aspects too like how do they wants making sales, how they actually get the product out and in a good way and then servicing the customers later on and answering their questions from there, just get a review and so it's really kind– it's a complex process so the– what I just said earlier about what's the engine behind it, well in that case, the engine is, are there good SOP's, is there a good team, is there like –what's kind of the new ones that has a loud– like some people, super good at branding and they're super good at that product launch process in Amazon and so that's kind of what's giving them the edge over the competition and other people were good with analytics and numbers and ratios and shipping cost, cost of good sold to whatever they're spending on customer service and all that kind of stuff. Which that's all fine but it's kind of that it's up front-end that's probably more important in Amazons like how they're interacting with the customer. Mark: Well this is why it's so important for pre-sellers to document their processes because a lot of this stuff is done almost from a skills like that is developed over years. Having those processes, documented, the stuff that you're doing on day-to-day basis helps buyers like you, Jeff or any of the buyers out there understand what's going on and try to sum it– that is as well. I want to go back about what you said about graphs because that really caught my attention. I–I'm with you on that. I love graphs. I think visualizing data, specifically the financial data is something people don't do enough. And I might geek out a little bit here, and save my finger craft that I used when I'm evaluating business myself, is year over year analysis that I like to look at both the revenue and to those gross profit. Definitely take a look at that if you're able to, if it's done on cruel basis. My discretionary earnings, it was a year-over-year because it soothes out some of the seasonality that you're naturally going to have in pretty much every business (0:31:12.3) has, even a little bit of seasonality. Is there a better–like a favorite approach or favorite sort of graph that you would recommend or any other piece of geo that you would look at to say, “Hey! Here's kind of a peak into the future or maybe what the drafts of help of these businesses” Jeff: First of all, I love year-over-year analysis too when you have a business that has enough historical data out there to be able to do that, and that's really, really helpful. But in terms of adding to that, for me, one of the important things is ratios and if you have a numbers degree, whether it's finance or accounting, whatever they teach you about that. But actually it's simpler than– you don't have to learn what you do in school. What it is, is your looking for things like the percentages of the cost that make up the total cost of the product or the service and a lot of times you can find problems where, for a few months, shipping was a lot of money or cost of product or cost advertising is a lot of money and then there's–and then some of those cost drop-off where the ratio changes, the percentage change radically. And for me, those are kind of– a lot of people are afraid of financial analysis in funnels but actually, we understand that what you're looking for is kind of that stability in the business and then a little– the flags or things that changes in the ratios, changes– the peaks and valleys in the chart. And is there good explanation for those peaks and valleys. Peaks and valleys are just fine. The only concern is what are the reasons behind those peaks and valleys and sometimes, for example, sellers, so they really have– they may not have any idea why they're getting more customers or any idea why they lost customers. And the big problem with that is that when you buy the site and something happens, you're not going to be able to get those customer back if you don't know the reasons for those things. So some of the tools and things that I look at. And also just say, they kind of end in the evaluation stage and stay on in due-diligence stage. One of most important tools for new buyers is to compare different sources of information, just in the content, for example, a lot of times, you'll have analytics reports then you have your ad network reports and sometimes you have bank statements, you have taxes, you have– you actually, a lot of times have a lot of different sources for very similar information and it's important to kind of compare those sources together to see if something's missing, something's kind of wack. And it kind of really helping, so in E-commerce is same thing, where a lot of times you'll have traffic and saying why I'm getting this many sales, repay-dues and then you have shopping cart software on your website, you have merchant processors who have similar data and then whatever is in half-thing in your back account and all of those things that's lying out. So , there's actually some, pretty simple tools, once your kind of aware them to take the mystique off of what're people are a little bit concerned about when they first enter business. Mark: Wow! there's– I kind of always restarted with this, rather than buy a big verse and buy a small sort of conversation that is a lot of details you get in to hear, but we are up against clock a little bit here. I think this idea of understanding the customer journey, understanding how they become customers, and the process they're involved there both can help any buyer understand how healthy a business is and how new was or how specialized they're going to have to be in their–works with that business but also potentially uncover some opportunities if there's leakage, for example in that customer journey wherein you're losing a lot of people at a certain step maybe they are taking advantage of cart abandonment technologies or maybe they don't have a good e-mail automation. Well these are opportunities that might be available for buyers. And then also this idea of looking at ratios; really, really solid advice. Jeff: Yeah, the ratios– what I will do again when I'm evaluating business is I'll look at cost of good sold– gross profits were the first things I will look at. Is that ratio staying healthy because you don't want a business where that's getting squeezed up at time or at least you need to understand that. But also you compare advertising to total revenue are you having to spend more just to keep the same revenue? Or has that owner adjusted another area so maybe they're spending more but cutting back on staff–But to make the bottom line look healthy but ,maybe lying underneath there's a few issues that you have to be aware of. Mark: I would love to sit and talk for a couple of hours because I think we could talk for a couple of hours. So, maybe what we'll do is we'll have you on again in the future and we can continue the conversation. In the meantime where can people learn more about you? Jeff: I've a website called “HeckYeah.org” and then “OwnOptimize.com” is where I'm selling my courses right now. So those are the two places. And yes Mark, I would love to– this is one of my favorite topics really is this idea. First time buyers, second, third time buyers; what are the questions that they have, which they look for and as you said, lots of things we could talk about. We're just barely scratching the surface so I'd love to come back and talk some more about it. Mark: Cool! Hey Jeff, thanks for coming on. Really appreciate you coming on and well, stay in touch. Jeff: Yeah, sounds good, great. Thanks a lot for having me. Links and Resources: Jeff's Website Jeff's Course The Website Investor

Welcome to Blind Abilities, I'm Jeff Thompson, and I am at the Sagebrush convention in Las Vegas and I ran into a fairly new vendor here amongst the senior vendors. I'm talking to Ivan Delgado. How are you dong? Ivan: Alright man, how about yourself? Jeff: Good, good, just enjoying the convention and all of the busy lights and stuff, and noises I should say out there. Ivan: Nice city huh? Jeff: Yeah, and you're from Vegas? Ivan: Yeah man, welcome to Las Vegas, if anybody is listening, come and enjoy Vegas, we love your guy's money. [laughter] Jeff: I noticed that! [laughter] So what got you interested the business enterprise program? Ivan: So about 3 or 4 years ago man, finishing up, not finishing, taking a break from college for certain reasons, whether it was lack of assistive technology or books not being ready for me, I decided to take a break and my lady actually told me about this program. She had a few friends that have done it in California and other states, and she told me, you like to boss me around so you might as well boss people around and try to make money. Yep, a couple years later man, I have been fortunate enough to finally get my own site and I started, originally I started the program. I got my BEP license about 2 years ago. My first site opened February 1st of last year, we just had our one year anniversary, before that we had vending machines at the location I am in. We just, it took a while for the location, the actual location to open up. Jeff: Is there training involved when you first join? Ivan: Yeah, when I first joined, now it's a lot different man, but when I first joined it was pretty intense, what I think is intense man. It was, I want to say 9 months man, and don't quote me on that. Classes started in March and the first three months were strictly just books and learning bi-laws, and how to do PNL's, and marketing, it was pretty awesome man, for someone like me that, you know never had a business, don't have an idea, i was just used to working 9 to 5s. It was very helpful. We did a couple of course through Hadley, Hadley School for the Blind online. We did that and then we did a couple of ServSafe tests here, customer service exams that we had to get. I am fortunate and I could brag about it man, because again, I am blessed man, and I think I am one of the only vendors here in Nevada that does his own profit and loss statement. You have vendors that are paying 200 to 300 dollars to, for people to input simple numbers and again, thanks to those classes, thanks to those three months of actually putting in work man, and understanding PNL's, and little Bi-laws, and stuff like that is definitely helpful man. Jeff: You are your own accountant. Ivan: Yes sir, thank God man! Jeff: You gotta keep the profits up right? Ivan: Right right, that is one way of doing it man, saving money man, all you gotta know is how to work. We know how to work man, it doesn't matter if you are disabled or not man, it's ambition, as humans we hunger for that ambition man. We have it, it is just a matter of if we want it or not man, and a lot of the times we don't want it man, and that sucks, but we are our own worst enemies and our own best friends man, and only we can get what we want man. Jeff: So what suggestions would you have for someone who is interested in getting into the business enterprise program? Ivan: A lot of patience. A lot of patience, hard work. Here in Nevada the process is a little longer due to the lack of operators we have, you know we kind of have to prove ourselves and that is fair I think. But a lot of patience and , just because you're disabled doesn't mean that stuff is going to be handed to us, especially here in the business world man, we have just as much of a responsibility as anybody else. Just keep your head up and be strong. That's it, just stay positive and stuff could be worse and if we are here and you are listening to this podcast, obviously we have gotten this far and the sky is the limit after here. Jeff: So what does Sagebrush bring to you? Ivan: A lot of a lot of information. A lot of people like Mr. Jeff, sorry if, I am bad at names, I think that's your name [laughter] Jeff, but yeah, this man, that working, as a blind community we have to become close man and I'm, the best example man, I don't go out a lot and I don't network but it hasn't changed man, I don't believe in NFB's, and NCB's, and ACB's, I wish there was only one. I don't see for this separation between organizations when really we're all just one, and that's blind. We're all blind so I would love for us to stick together and become one. I think if we become one a lot of people would be aware of both our disabilities, of our business and the Randolph Sheppard Act, again if we advocate be strong, stay positive and network, go out to these kinds of meetings, kind of conferences, I think this could very well be accomplished. There is a lot of older gentleman and ladies that are in the program and it's time for younger generations to step up and I think this is the time. Jeff: There is a lot of wealth of information, they have been in it, they have seen it change, and that is the bigger thing that things have changed and now here you are paving your way, you know, you're two years in, pretty soon you'll probably be leading the show here. Ivan: Absolutely, and those are the plans man, and absolutely, we always have to be grateful to the people that have, that started this man you know, and we've gotten a long ways man, I mean from selling newspapers at Post Offices to you know, having places at Hoover Dam's or at airports, you know that's a huge accomplishment, and that couldn't have been done without the people that you know, are moving on or retiring now. And that is a huge gratitude to you guys, we thank you. Jeff: Well, Ivan Delgado thank you very much for taking your time away from the karaoke. You gonna sing out there? Ivan: No we already did man, I need two more shots, I think these last two shots were on you. [laughter] Jeff: Do you have an email? Ivan: Yeah man, that's ivan.delvilla@gmail.com. Jeff: Alright, well thank you very much for taking the time and just speaking on Blind Abilities. Ivan: Yes sir, have a good day! [Music] Jeff: So if you are interested in the business enterprise program, becoming your own business owner, entrepreneur, check it out with your division of vocational rehab, your State Services for the Blind and see what they can do for you.
