Abstract 236: Gender Disparities in Bystander CPR and Defibrillation Persist in Black and Hispanic Neighborhoods in the US
Bystander CPR (B-CPR) and defibrillation for sudden cardiac arrest (SCA) vary by gender with females being less likely to receive these interventions. Despite known differences by race and ethnicity, it is unknown whether gender disparities in B-CPR and defibrillation persist by neighborhood race and ethnicity.
We examined the likelihood of receiving B-CPR and defibrillation by gender stratified by public location and neighborhood racial/ethnic composition. We hypothesized that in public locations within Black neighborhoods, females will have a lower likelihood of receiving B-CPR compared to males.
We conducted a retrospective cohort study using data from the US Cardiac Arrest Registry to Enhance Survival (CARES) registry. Neighborhoods were classified by census tract based on percent of Black or Hispanic residents using the threshold in the definition of “White flight” where Whites leave a neighborhood when it exceeds >30% of a minority population. We independently modeled the likelihood of receipt of B-CPR and defibrillation by gender stratified by public location and neighborhood racial/ethnic composition controlling for confounding variables.
From 2013-2018, CARES collected 350,722 US arrests; after excluding pediatric arrests, those witnessed by EMS, or those that occurred in a healthcare facility, 214,464 were included. Mean age was 64±16 and 65% were male; 39% received B-CPR, 9% received bystander defibrillation prior to 9-1-1 responders arrival, and 18% occurred in the public. In Black neighborhoods, females who had SCA in public locations were 22% less likely to receive B-CPR (OR: 0.78 (0.64-0.95), p=0.01) and 42% less likely to receive defibrillation (OR: 0.58 (0.45-0.74), p<0.01) compared to males. In Hispanic neighborhoods, females who had SCA in public locations were also less likely to receive B-CPR (OR: 0.72 (0.59-0.87), p<0.01) and less likely to receive defibrillation (OR: 0.62 (0.48-0.80), p<0.01) compared to males.
Females with public SCA have a decreased likelihood of receiving B-CPR and defibrillation, and these findings persist in Black and Hispanic neighborhoods. This has implications for strategies to reduce disparities around bystander response to SCA.
