Racial and ethnic differences in outcomes after out-of-hospital cardiac arrest: Hispanics and Blacks may fare worse than non-Hispanic Whites

This study evaluates differences in out-of-hospital cardiac arrest (OHCA) characteristics, interventions, and outcomes by race/ethnicity. This is a retrospective analysis from a regionalized cardiac system. Outcomes for all adult patients treated for OHCA with return of spontaneous circulation (ROSC) were identified from 2011–2014. Stratifying by race/ethnicity with White as the reference group, patient characteristics, treatment, and outcomes were evaluated. The adjusted odds ratios (OR) for survival with good neurologic outcome (cerebral performance category 1 or 2) were calculated. There were 5178 patients with OHCA; 290 patients excluded for unknown race, leaving 4888 patients: 50% White, 14% Black, 12% Asian, 23% Hispanic. In univariate analysis, compared with Whites, Blacks had fewer witnessed arrests (83% vs 86%, p = 0.03) and less bystander CPR (37% vs 44%, p = 0.005), were less likely to undergo coronary angiography (14% vs 22%, p
