EMS agencies impact bystander interventions during out-of-hospital cardiac arrest

Abstract

"Bystander CPR rates and AED use in out-of-hospital cardiac arrest (OHCA) vary widely across EMS service areas in Missouri. EMS agencies report the number and outcome of OHCAs in their service area annually, in addition to other data points; this data is compiled into the Cardiac Arrest Registry to Enhance Survival (CARES) database. Both CPR and AED use by the public in OHCA are associated with increased survival to discharge."--Background.
