Study Objective: 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., Methods: The study comprised 2 phases. The development phase involved reviewing CPR videos, categorizing problems, and formulating strategies using the Systems Engineering Initiative for Patient Safety model. Resuscitation tasks were organized into A-C-L-S domains using hierarchical task analysis. Equipment and environmental deficits were optimized ergonomically with a pit-crew style arrangement. Mnemonics enhanced teamwork and leadership. The evaluation phase assessed postimplementation ED resuscitation team performance, focusing on adherence, timeliness, and quality of A-C-L-S tasks., Results: The development phase produced a structured teamwork model, assigning tasks, tools, mnemonics, and positions based on A-C-L-S domains. The A-team manages the airway and optimizes end-tidal CO 2 levels; the C-team focuses on high-quality chest compressions and defibrillation. Leadership coordinates resuscitation efforts using goal-directed mnemonics (DABCD 2 E 3 ), whereas the S-team handles medications, timekeeping, and recording. The evaluation phase showed improvements in adherence and timeliness of A-C-L-S tasks, with sustained increases in chest compression fraction before mechanical CPR, from 67.2% preimplementation to 83.0% postimplementation, 89.1% after 1 year, and 86.1% after 2 years. Overall, chest compression fraction also improved from 81.7% to 88.6%, peaking at 92.2% after 1 year and maintaining 90.8% after 2 years., Conclusion: The A-C-L-S teamwork model is feasible, applicable, and effective. Further research is needed to assess its influence on patient outcomes., (Copyright © 2024 American College of Emergency Physicians. Published by Elsevier Inc. All rights reserved.)

Study Objective: The effect of out-of-hospital intubation in patients with out-of-hospital cardiac arrest remains controversial. The Taipei City paramedics are the earliest authorized to perform out-of-hospital intubation among Asian areas. This study evaluates the association between successful intubation and out-of-hospital cardiac arrest survival in Taipei., Methods: We analyzed 6 years of Utstein-based registry data from nontrauma adult patients with out-of-hospital cardiac arrest who underwent out-of-hospital airway management including intubation, laryngeal mask airway, or bag-valve-mask ventilation. The primary analysis was intubation success on patient outcomes. The primary outcome was survival to discharge and the secondary outcomes included sustained return of spontaneous circulation and favorable neurologic survival. Sensitivity analysis was performed with intubation attempts rather than intubation success. Subgroup analysis of advanced life support-serviced districts was also performed., Results: A total of 10,853 cases from 2008 to 2013 were analyzed. Among out-of-hospital cardiac arrest patients receiving airway management, successful intubation, laryngeal mask airway, and bag-valve-mask ventilation was reported in 1,541, 3,099, and 6,213 cases, respectively. Compared with bag-valve-mask device use, successful out-of-hospital intubation was associated with improved chances of sustained return of spontaneous circulation (adjusted odds ratio [aOR] 1.91; 95% confidence interval [CI] 1.66 to 2.19), survival to discharge (aOR 1.98; 95% CI 1.57 to 2.49), and favorable neurologic outcome (aOR 1.44; 95% CI 1.03 to 2.03). The results were comparable in sensitivity and subgroup analyses., Conclusion: In nontrauma adult out-of-hospital cardiac arrest in Taipei, successful out-of-hospital intubation was associated with improved odds of sustained return of spontaneous circulation, survival to discharge, and favorable neurologic outcome., (Copyright © 2017 American College of Emergency Physicians.
