Scribe use throughout health care is becoming more common. There is limited peer-reviewed literature supporting this emerging role in health care despite rapid uptake of the role. ⋯ Scribes had a positive impact on RVUs in adult but not pediatric patients. Among adults, scribes led to higher RVUs in ESI 2 and 3 but not 4 and 5 patients, perhaps suggesting a limitation to improve revenue capture on lower-acuity patients.

Each application cycle, emergency medicine (EM) residency programs attempt to predict which applicants will be most successful in residency and rank them accordingly on their program's Rank Order List (ROL). ⋯ USMLE Step 1 score rank and adjusted ROL position did not predict resident performance at time of graduation. However, adjusted ROL position was predictive of future residency success in the subgroup of residents who had completed a sub-internship at their respective programs. These findings should guide the future selection of EM residents.

The electronic medical record is a relatively new technology that allows quick review of patients' previous medical records, including previous electrocardiograms (ECGs). Previous studies have evaluated ECG patterns predictive of pulmonary embolism (PE) at the time of PE diagnosis, though none have examined ECG changes in these patients when compared with their previous ECGs. ⋯ The most common ECG changes when compared with previous ECG in the setting of PE are T wave inversion and flattening, most commonly in the inferior leads, and occurring in approximately one-third of cases. Approximately one-quarter of patients will have a new sinus tachycardia, and approximately one-quarter will have no change in their ECG.

Takayasu arteritis, also known as "pulseless disease," causes proximal occlusion of the lumen of large arteries of the neck and arm, leading to impalpable pulses and "pseudohypotension." This may misdirect the management plan for a patient in the emergency setting if the presence of vascular occlusion is not previously known. ⋯ We describe a young woman who presented to the emergency department (ED) with fever. On evaluation, she had shock, which was not responsive to a fluid bolus. Bedside Rapid Diagnostic Test was positive for Plasmodium vivax, and a diagnosis of severe vivax malaria was made. She was started on intravenous artesunate and vasopressors in view of her persistent hypotension in the face of a normal central venous pressure. A thorough examination at that time revealed palpable lower limb pulses with feeble upper limb pulses. Vasopressors were tapered while monitoring lower limb blood pressure. Computed tomographic angiogram confirmed the diagnosis of Takayasu arteritis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Hypotension and shock are regularly encountered in the ED. Occlusive arterial disease involving upper limbs can mimic refractory shock, leading to potentially harmful and unnecessary interventions. Emergency physicians should be aware of this possibility. A simple routine of quickly checking all peripheral pulses would help them avoid this pitfall.

Case Reports
An Unusual Case of Alternating Ventricular Morphology on the 12-Lead Electrocardiogram.
One of the principal tasks of an emergency physician is identifying potentially life-threatening conditions in the undifferentiated patient; cardiac dysrhythmia is an example of such a condition. A systematic approach to a patient with atypical dysrhythmia enables proper identification of such-life threatening conditions. ⋯ We describe a 31-year-old man presenting to the emergency department with an undifferentiated dysrhythmia after naloxone reversal of an opiate overdose. A systematic approach to the electrocardiogram led to the rare diagnosis of Wolff-Parkinson-White (WPW) alternans. We review the differential diagnosis of this dysrhythmia and the initial evaluation of a patient with the WPW pattern present on their electrocardiogram. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be prepared to use a systematic approach to an undifferentiated dysrhythmia to identify potentially life-threatening conditions.
