Intro: Making Sense of the Nonsense

Seemingly unreasonable ED requests usually reflect a mismatch between patient goals and emergency department scope, not simple irrationality. The clinically useful move is to separate the truly unsafe ask from the underlying concern, then answer the concern without defaulting to a reflexive no. Handling Unreasonable ED Requests Scope versus underlying need: Most unreasonable requests are really requests for reassurance, speed, or risk reduction, so the first job is to identify the why before deciding whether the test itself belongs in the ED. Two patient categories: A small minority are truly irrational, but far more patients are asking the wrong question for a reasonable reason, like fear triggered by a family member's prior catastrophic diagnosis. Six demand mechanisms: A realist review found six recurring drivers for these visits, including risk minimization, need for speed, low treatment-seeking burden, compliance, consumer satisfaction, and frustration. Non-gatekeeper communication: Avoid framing yourself as the gatekeeper of tests; a better script is to explain that one option is possible but an alternative fits the ED setting better. We get into the wording in the episode. Flow-conscious accommodation: If the request is low risk but operationally slow, a vertical area or hallway workflow may preserve department flow while setting expectations that the visit could take all day. Reassurance as treatment: The parent of a mildly ill child or the patient wanting a head CT on the anniversary of a relative's glioblastoma often needs an expert exam and explicit reassurance more than imaging.

How High is Too High? Asymptomatic Severe Hypertension

Asymptomatic severe hypertension is usually not a hypertensive emergency; the key ED question is whether there is end-organ injury. In patients with markedly elevated blood pressure but no symptoms, routine ECGs and broad testing rarely help, and discharge planning often matters more than acute blood pressure reduction. Asymptomatic Severe Hypertension Approach Symptom-first triage: The central decision is symptomatic versus asymptomatic hypertension, because severe blood pressure elevation alone is not an emergency unless it is causing acute end-organ injury. Severe blood pressure definition: Marked elevation generally means SBP above 180 mmHg or DBP above roughly 115 to 120 mmHg, but the number matters less than whether symptoms or subtle exam findings suggest harm. Hypertensive emergency screen: True emergencies are the classic end-organ syndromes such as ACS, aortic dissection, SAH or ICH, acute pulmonary edema, encephalopathy, and stroke. We walk through the bedside distinction in the episode. Slow disease framing: Hypertension causes injury over weeks to months to years, not minutes to hours, which is why aggressive ED lowering in an otherwise well patient can create more risk than benefit. Rest and repeat effect: A calm dark room and repeat measurement after 20 minutes will lower systolic pressure by more than 20 mmHg in over one-third of patients, a useful reminder to confirm the number before reacting. Testing, Treatment, and Discharge Minimal routine testing: Routine ED testing is usually unnecessary in asymptomatic severe hypertension, including an ECG, because abnormal screening rarely changes immediate management in a patient without end-organ symptoms. Selective metabolic panel use: If readily available, a basic metabolic panel can be helpful for baseline creatinine, electrolytes, and potassium when those results will influence which outpatient antihypertensive you start. Straightforward first-line agent: Amlodipine 5 mg daily is the simplest ED start for many patients because it is well tolerated, lab-light, and lowers systolic pressure by about 15 mmHg. Renal disease medication choice: Patients with renal insufficiency are a notable exception, where an ACE inhibitor or ARB is generally preferred over a calcium channel blocker for initial outpatient therapy. Short-acting drug avoidance: Avoid nifedipine, nitroglycerin, clonidine, and hydralazine for asymptomatic severe hypertension because rebound hypertension and overshoot hypotension can cause downstream complications. We get into the practical why in the chapter. Discharge follow-up instructions: Home blood pressure logs, calm twice-daily checks, primary care follow-up within a week, and return precautions for chest pain, severe headache, vision change, or edema matter more than chasing the ED number.

Lit Matters 1: Identifying Medical Error By Asking: WYHDSD?

Medical error review in emergency medicine often blurs true error, adverse outcome, and reasonable judgment under pressure. A single peer-review question — would you have done something differently — may be a practical ED quality-assurance screen with very high sensitivity and an exceptional negative predictive value. WYHDSD as an Error Screen Single-question screen: Asking a peer reviewer whether they would have done something differently identified nearly all adjudicated ED errors, with 97.4% sensitivity and a 99.8% negative predictive value. Practical QA signal: A “no” answer was rarely associated with missed error, making WYHDSD most useful as a rule-out screen when a case enters quality review in the first place. High-risk case selection: The cohort came from classic QA triggers such as 72-hour return with admission, early ICU upgrade, death within 24 hours, or clinician-initiated referral. We get into why that matters in the episode. Error versus outcome: The study usefully separates error from adverse events, underscoring that a bad outcome alone is not synonymous with a mistake in emergency care decision-making. Adjudication caveat: Reviewer judgments were not blinded from the usual historical review context, so WYHDSD looks compelling as an adjunct now but not yet a clean replacement for existing QA methods.

A GI Doc's Take on the 2021 UGIB Guidelines

Upper GI bleeding management has shifted toward tighter risk stratification, more selective transfusion, and less reflexive overnight endoscopy. A Glasgow Blatchford Score of 0-1 identifies very-low-risk patients for discharge, while unstable hemorrhage, suspected varices, and anticoagulation reversal still demand a more nuanced bedside approach. UGIB Risk Stratification and Disposition Glasgow Blatchford low risk: A Glasgow Blatchford Score of 0-1 is the key discharge cutoff in the 2021 ACG guidance, identifying very-low-risk UGIB patients who can usually avoid admission with prompt GI follow-up. Clinical override for liver disease: A reassuring score should not overrule bedside concern for occult cirrhosis or varices; a history of alcohol use, stigmata of liver disease, or exam findings may justify a more conservative plan. Restrictive transfusion threshold: For most UGIB patients, transfusion starts at hemoglobin 7 g/dL, with 8 g/dL favored in cardiovascular disease; exsanguinating or hypotensive patients are the important exception. Early instability exception: The guideline’s low-risk and restrictive-transfusion recommendations do not apply cleanly to shock physiology, where hemodynamics matter more than the first lab value. We get into those bedside exceptions in the episode. Pre-Endoscopy Medical Therapy Proton pump inhibitor upfront: Pre-endoscopic PPI therapy is reasonable despite guideline uncertainty, because it appears to reduce high-risk stigmata and the need for endoscopic hemostatic therapy at index scope. Erythromycin before scope: Erythromycin 250 mg IV given 20-90 minutes before endoscopy improves gastric visualization by clearing clot burden and is associated with fewer repeat procedures and shorter stays. Octreotide for variceal concern: Octreotide is not broadly endorsed for all-comer UGIB in this guideline, but suspected variceal bleeding remains the classic indication because it lowers splanchnic blood flow. Antibiotics in cirrhosis: Any UGIB patient with suspected varices or underlying liver disease should get antibiotics, with ceftriaxone the usual first choice because it lowers mortality, infections, and likely rebleeding. Endoscopy Timing and Escalation Twenty-four hour endoscopy window: For stable admitted patients, endoscopy within 24 hours is now the headline target; the older push for under-12-hour scoping did not improve mortality or rebleeding in trials. Resuscitation before urgent scope: The reason timing relaxed is practical physiology: under-resuscitated patients do worse, and a daytime endoscopy unit often offers safer resources than a rushed overnight procedure. Shock changes the timeline: Persistent hypotensive shock is the major exception to the 24-hour window and should trigger emergent GI involvement rather than passive adherence to the routine clock. Embolization after failed hemostasis: Transcatheter arterial embolization is the next-line move for bleeding ulcers after failed endoscopic therapy, and it can enter earlier when endoscopy is not feasible. We walk through that escalation point in the chapter.

Lit Matters 2: Can Anchoring Bias Mislead in CHF and PE Diagnosis?

Anchoring bias can narrow emergency department workups before the clinician ever sees the patient. In dyspnea with known CHF, triage framing that names heart failure was associated with less pulmonary embolism testing and more BNP ordering, a useful prompt to consciously reopen the differential. Anchoring Bias in Dyspnea and CHF Triage framing effect: A chief complaint that explicitly mentioned CHF shifted downstream decision-making in shortness-of-breath visits, suggesting the triage summary can act as an early anchor before bedside assessment begins. Pulmonary embolism workup: Among CHF patients with dyspnea, PE testing was ordered less often when CHF appeared in the pre-physician record, despite PE remaining an important competing diagnosis. BNP ordering pattern: BNP was obtained more frequently when CHF was named up front, a concrete sign that the initial frame pushed clinicians toward a heart-failure-first pathway. Missed versus delayed PE: ED PE diagnoses were lower in the CHF-mentioned group, while 30-day PE diagnoses were nearly unchanged, raising the possibility of delayed recognition more than true absence of disease. We get into that distinction in the episode. Study scale and limits: This was a VA cross-sectional review of 108,019 visits across 104 hospitals, but unmeasured bedside findings like edema or hemoptysis still limit any claim that triage wording alone caused bias. Bedside cognitive reset: The practical move is not to distrust triage but to deliberately rebuild the differential in dyspnea, especially when an obvious label like CHF arrives before your own exam.

High Risk, Low Prevalence: Adult Epiglottitis

Adult epiglottitis is uncommon but dangerous, and a normal throat exam does not make it safe to dismiss. The classic ED trap is severe sore throat with dysphagia, voice change, or drooling despite an unimpressive oropharynx, with diagnosis hinging on airway-aware visualization and imaging. Adult Epiglottitis Recognition and Management Normal throat exam trap: About 90% of adults with epiglottitis have a normal posterior oropharyngeal exam, so pain out of proportion, drooling, and voice change matter more than a reassuring look. High risk bounce-back features: Worsening sore throat over 12 to 24 hours, toxic appearance, tripod positioning, or subjective dyspnea should raise concern for impending airway compromise rather than routine pharyngitis. Direct visualization diagnosis: Definitive diagnosis comes from seeing the epiglottis with a dental mirror, flexible endoscope, or carefully performed laryngoscopy. We get into the bedside exam tricks in the episode. Imaging with airway caution: CT with contrast is the gold-standard test, while lateral neck films can show a thumbprint sign but miss too many cases to rule disease out; road-test supine tolerance before the scanner. Antibiotic coverage priorities: Empiric therapy should cover Streptococcus, Staphylococcus, and MRSA with agents such as ceftriaxone or ampicillin-sulbactam plus vancomycin, while routine metronidazole is unnecessary. Preferred airway approach: Roughly 13% of patients need intubation, and a flexible intubation endoscope is the preferred ED technique; supraglottic devices are avoided because they can worsen obstruction.

One Physician's Battle with Addiction

Substance use disorder in physicians is common, underrecognized, and especially relevant in emergency medicine. Addiction is a brain disease marked by prefrontal cortical atrophy, dopamine D2 downregulation, and mesolimbic reward-pathway remodeling, with confidential recovery pathways that allow many clinicians to return safely to practice. Physician Substance Use Disorder Prevalence and specialty risk: Physician substance use disorder is not rare; roughly 10-15% of physicians are affected over a career, with emergency medicine, anesthesiology, and psychiatry carrying some of the highest risk. Addiction as brain disease: Addiction reflects neurobiologic injury rather than moral failure, with prefrontal cortex atrophy, dopamine D2 receptor downregulation, and mesolimbic reward-pathway reorganization driving compulsive use. Common substances misused: Alcohol is the leading substance, followed by opioids and other prescribed sedating or mood-altering medications, a pattern that often blurs stress relief with self-treatment in clinicians. Drivers of ongoing use: Fear of licensure action, job loss, lawsuits, and shame keeps many physicians hidden long after impairment begins. Dr Rifenbark's lived experience makes that progression worth hearing in the episode. Suicide risk signal: Substance use disorder in physicians travels with a markedly higher suicide burden, including about 40% higher occurrence in male physicians and 130% higher occurrence in female physicians. Recovery Pathways for Clinicians Physician Health Programs: Physician Health Programs operate in 47 states and provide confidential evaluation, referral, treatment coordination, and monitoring tailored to healthcare professionals returning to practice. Five-year recovery outcomes: PHPs have strong longitudinal results, with 78% of participants remaining substance-free at five years and 71% retaining both licensure and employment. Professional-specific treatment options: Caduceus groups and treatment centers for healthcare professionals address recovery in the context of clinical identity, workplace access, and return-to-duty expectations. Core recovery team: A durable treatment plan usually includes a board-certified addiction medicine specialist, a therapist, and peer recovery support, with practice-specific nuances we get into in the chapter. Medication treatment considerations: Buprenorphine with or without naltrexone remains part of evidence-based addiction care, but physician return-to-work rules vary by state and can complicate practice decisions.

Lit Matters 3: Who's Smarter: Young Doctors, Or Old Doctors?

Emergency physician age was associated with short-term mortality in a large Medicare ED cohort, but the finding is observational and not a verdict on any individual clinician. The signal was small, persisted after adjustment, and raises harder questions about experience, risk tolerance, and what outcomes actually matter. Physician Age and ED Mortality Large Medicare cohort signal: In roughly 2.6 million ED visits among patients aged 65 to 89, younger emergency physicians were associated with lower 7-day mortality than older colleagues. Headline effect size: Each 10-year increase in physician age tracked with a 0.04 percentage-point rise in 7-day mortality, a small absolute effect that still matters at population scale. Adjusted association persists: The mortality difference remained after adjustment for measured confounders, which strengthens the association without proving causation. We get into that distinction in the episode. Severity-dependent pattern: The age signal was more apparent in higher-acuity visits and absent in low-illness-severity encounters, suggesting the difference emerges most under greater diagnostic and management pressure. Admission-rate paradox: Older physicians had lower admission rates, but that pattern did not explain the mortality finding, pointing instead toward differences in risk tolerance or decision style. Limits of interpretation: This study only examined Medicare patients and used 7-day mortality as the primary outcome, leaving patient preferences, costs, and younger populations outside the frame. What the Finding Might Mean Age versus cohort effect: One explanation is age-related change in working memory, stamina, or cognitive speed; another is cohort effect, where training era shapes current practice more than age itself. Board certification clue: If older training pathways were the main driver, you might expect board-status differences to track mortality more strongly, but that signal was not there. Volume and setting check: The association did not materially change across physician volume or academic versus nonacademic settings, which argues against a simple exposure or environment explanation. Mortality is not everything: A lower death rate is important, but it does not capture patient experience, goal-concordant care, or costs, especially in older adults with limited life expectancy. Practice introspection prompt: The useful takeaway is not that younger doctors are better; it is that every emergency physician should examine how habits, evidence drift, and risk tolerance shape bedside decisions.
