Disparities Regarding Inadequate Automated External Defibrillator Training and Potential Barriers to Successful Cardiac Resuscitation in Public School Systems

Abstract

Installation of automated external defibrillators (AEDs) in public schools has been shown to improve outcomes for children with sudden cardiac arrest (SCA). However, the adequacy of faculty AED training and potential barriers to successful cardiac resuscitation remain unknown. A questionnaire was mailed to all public schools in the state of Illinois (n = 3796). The survey focused on the demographic variables of each school as well as the confidence of the responder regarding effectiveness of AED training. 2,192 surveys were included in this study (58% response rate). Independent variables for perceived inadequate AED training were schools that were predominantly black (odds ratio [OR] 3.93; 3.01 to 5.13) or Hispanic (OR 2.75; 2.11 to 3.58), elementary schools (OR 2.05; 1.69 to 2.50), schools with <250 students (OR 1.69; 1.19 to 2.40) and <25 faculty (OR 1.54; 1.10 to 2.15). Eighty-eight percent of responders cited at least one barrier to successful AED utilization. Location in a town setting (OR 9.34; 4.73 to 18.44) or rural setting (OR 3.18; 2.47 to 4.10) as well as upper socioeconomic status (OR 3.85; 2.04 to 7.29) were found to be predictors of schools with no barriers to AED utilization.
