Measure	Time frame
- Status at hospital admission (return of spontaneous circulation [ROSC] vs. ongoing cardiopulmonary resuscitation) - Survival at 24 hours, 72 hours, 7 days, 30 days, and survival to hospital discharge - Neurological outcome at discharge, assessed using the Cerebral Performance Category (CPC) score and, where available, the modified Rankin Scale (mRS) - Associations of these outcomes with OHCA location and socioeconomic factors - EMS response times, treatment intervals, and prehospital interventions in relation to location and socioeconomic factors	—
