Males had an increased likelihood of receiving Bystander Cardiopulmonary Resuscitation (BCPR) compared with females in public. BCPR improved survival to discharge, with greater survival among males compared with females. Analyzed data from adult, nontraumatic OHCA events within the Resuscitation Outcomes Consortium registry (2011–2015). Using logistic regression, we modeled the likelihood of receiving BCPR by gender, including patient-level variables, stratified by location. A cohort of 19 331 OHCAs was assessed. Mean age was 64±17 years, and 63% (12 225/19 331) were male.
