Time indices are key elements in prehospital medical emergencies. The number of calls to Emergency Medical Services (EMS) and the number of missions they have undertaken have been impacted by the COVID-19 epidemic. ⋯ Even though the structure of Iran's emergency system is based on the American-Anglo model, and rapid patient transfers to medical facilities are prioritized, the COVID-19 epidemic resulted in increased calls and missions and affected time indices. Therefore, it is suggested that the method and type of service provision be modified during similar crises.

Adolescent substance use is a growing public health concern, particularly given rising mortality rates from drug overdose deaths. The emergency department (ED) provides a unique opportunity to screen adolescents for substance use and provide brief interventions and linkage to care. ⋯ ED-based adolescent substance use screening and interventions are necessary, feasible, and acceptable, but understudied. Future studies, focusing on optimizing ED interventions and linkage to care, are important next steps in determining the best care for adolescents with substance use who present to the ED.

Randomized Controlled Trial Comparative Study
A Cluster-Randomized Control Study Comparing a New Cue "Two Compressions per Second" with "100-120 Compressions per Minute" in Training of Bystander Cardiopulmonary Resuscitation.
Chest compression at a rate of 100-120 compressions per minute (cpm) during cardiopulmonary resuscitation (CPR) is associated with the highest survival rates. Performing compressions at a faster rate may exhaust the rescuers. ⋯ The new cue of 'two compressions per second' resulted in participants having a lower compression rate, although it still exceeded 120 cpm.

Patients with congenital long QT syndrome (LQTS) are prone to ventricular dysrhythmia but may be initially asymptomatic with a normal QTc interval on resting electrocardiogram (ECG). Albuterol is listed as a medication that poses a "special risk" to patients with congenital LQTS, but its effects have been rarely described. We present a case of previously unknown, asymptomatic congenital LQTS unmasked by albuterol in an adolescent with asthma. ⋯ A 12-year-old girl with a history of asthma presented to the emergency department (ED) with shortness of breath, wheezing, and tachycardia for 24 h, consistent with acute asthma exacerbation. She received two doses of her home albuterol inhaler 2 h prior to presentation. Initial ECG demonstrated a QTc of 619 ms. Her remaining history, clinical examination, and laboratory workup, including electrolytes, were unremarkable. She was observed with cardiac monitoring before being discharged from the ED in stable condition for next-day outpatient pediatric cardiology follow-up. Resting office ECGs revealed QTcs from 440-470 ms. Exercise stress test revealed QTc prolongation of 520 ms and 500 ms at minute-2 and minute-4 of recovery, respectively. Genetic testing revealed heterozygous pathogenic variants in KCNQ1, consistent with type 1 LQTS. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Albuterol may be a cause of marked QTc prolongation in ED patients with underlying congenital LQTS, which can be a diagnostic clue in previously unidentified patients. Extreme QTc prolongation also serves as an indication in the ED for Cardiology consultation, laboratory evaluation for electrolyte imbalances, and observation with cardiac monitoring.

As end-stage renal disease becomes more prevalent in the United States, the number of Americans with arteriovenous (AV) fistulas continues to increase. One of the most feared complications of AV fistulas is life-threatening hemorrhage, as patients can exsanguinate within minutes. ⋯ To our knowledge, this is the first published task trainer model to simulate a bleeding AV fistula for EM residents. The model was well received by our trainees, is relatively inexpensive, and made from easily sourced materials. We believe this model can be used for trainees of all disciplines to prepare them for this potentially catastrophic patient presentation.
