Abstract

Objective: Sudden cardiac arrest (SCA) in the young is a rare event but the effects can be devastating. We sought to identify variables that would lead to an improvement in time to defibrillation (TDFB), a previously noted factor significantly influencing survival from cardiac arrest. Design: During the 2013–2014 academic year, the Clark county school district performed quarterly drills to practice the coordinated automated external defibrillator (AED) response. Variables including school, AED carrier, and drill characteristics were measured to determine influence on TDFB. Schools were grouped by TDFB at a cutoff of three minutes. Characteristics were sought for schools with TDFB below three minutes. A mixed regression model taking into account repeated measures was created to determine which variables influenced TDFB. Results: Time to overhead announcement, distance of AED from drill site, and time to setup AED were the variables influencing TDFB with statistical significance (P <.01). Conclusions: This study supports the notion of early recognition, announcement, and close proximity to an AED during a SCA to ensure an early TDFB. These results are consistent with basic life support and the chain of survival tenets of the American Heart Association. © 2016 Wiley Periodicals, Inc.
