Data in the Aus-ROC Epistry includes information on the out-of-hospital cardiac arrest event, demographics, arrest features, response times, treatment and outcome (see below). Variables were identified by consensus among representatives from the participating ambulance services. Data is collected according the the ILCOR OHCA Utstein Template definitions. The primary outcome measure is survival to hospital discharge/survival to 30-days, with survival to hospital and rreturn of spontaneous circulation (ROSC) key secondary outcomes.
