    Cardiopulmonary resuscitation (CPR) is critical for out-of-hospital cardiac arrest patients but is prone to rapid changes and errors. Effective teamwork and leadership are essential for high-quality CPR. We aimed to introduce the Airway-Circulation-Leadership-Support (A-C-L-S) teamwork model in the emergency department (ED) to address these challenges. ⋯ The A-C-L-S teamwork model is feasible, applicable, and effective. Further research is needed to assess its influence on patient outcomes.

    Observational StudyDoor-in-Door-Out Times at Referring Hospitals and Outcomes of Hemorrhagic Stroke.Interhospital transfer is often required in the care of patients with hemorrhagic stroke. Guidelines recommend a door-in-door-out (DIDO) time of ≤120 minutes at the transferring emergency department (ED); however, it is unknown whether DIDO times are related to clinical outcomes of hemorrhagic stroke. ⋯ These findings suggest that EDs currently expedite the transfer of the sickest patients; however, prospective studies and more granular data are needed to understand the impact of early treatment and timing of transfer for patients with hemorrhagic stroke.

    To evaluate for increases in the use and costs of respiratory viral testing in pediatric emergency departments (EDs) because of the COVID-19 pandemic. ⋯ Respiratory testing and associated costs increased during the COVID-19 pandemic and were sustained despite decreasing incidence of disease. These findings highlight a need for further efforts to clarify indications for viral testing in the ED and efforts to reduce low-value testing.
