Acute cardiac care & resuscitation
Cardiac Arrest Survival at Emergency Medical Service Agencies in Catchment Areas With Primarily Black and Hispanic Populations
Authors' conclusion
Risk-standardized survival rates for OHCA were 1.9% lower at EMS agencies working in Black and Hispanic catchment areas than in White catchment areas. This difference was not explained by EMS response times, rates of EMS termination of resuscitation, or first responder rates of initiating cardiopulmonary resuscitation or applying an automated external defibrillator.
Study context
- Population
- Adults with nontraumatic Out-of-hospital Cardiac Arrest (OHCA), Cardiac Arrest Registry to Enhance Survival, 2015–2019
- Participants

- Black and Hispanic catchment areasn = 82
- Outcome
- Agency-level risk-standardized survival rate (RSSR) to hospital admission
