Abstract 266: Texas Out of Hospital Cardiac Arrest Gender Disparities From Statewide Out-of-Hospital Cardiac Arrest Data Registry - The Texas Cares Project

Abstract

Introduction: Female out-of-hospital cardiac arrest (OHCA) victims experience differences in care and worse rates of survival compared to male victims. Gender differences in time spent by prehospital care teams on scene with patients has not been studied. Hypothesis: There are gender disparities in scene time and outcomes. Increased scene time is associated with worse outcomes for Males and Females. Methods: We performed a retrospective, cohort study of the Texas Cardiac Arrest Registry to Enhance Survival (CARES) from 2014-201. We included adult OHCAs not witnessed by prehospital personnel that included scene time data and did not result in return of spontaneous circulation in the field that were transferred to emergency departments for ongoing resuscitation. We described OHCA demographics. We evaluated the association between gender and scene time. Using multivariable logistic regression, we evaluated the association of scene time with favorable neurologic outcome, (cerebral performance category (CPC) of 1 or 2). Results: We include 11,782 encounters with OHCA not witnessed by prehospital personnel, of these 7,185 were male and 4,597 female. Female OHCAs were older than male (mean 63.7 vs 61.3, p < 0.01). Female patients had slightly longer scene times than males (mean 29.2 vs 27.9). Female patients were less likely to have favorable neurologic outcomes (12.5% women vs 17.3% men, p < 0.01 by chi2). Adjusting for age, gender, race, initial rhythm and bystander CPR in the multivariable model, increased scene time remained associated with a lower odds of favorable neurologic outcome (OR 0.96, 95%CI 0.95-0.96). Conclusions: OHCAs with longer duration scene time were associated with a lower likelihood of favorable neurologic outcome. Female patients were likely to have longer scene time duration and worse rate of favorable neurologic outcome.
