Acute cardiac care & resuscitationCohort study
Public Out-of-Hospital Cardiac Arrest in Residential Neighborhoods
- Observational cohort study
- multicentre
- Vienna and Copenhagen registries
Authors' conclusion
Two-thirds of public OHCAs occurred in residential neighborhoods with fewer resuscitative efforts before ambulance arrival and lower survival than in nonresidential areas.

- Exposure
- Public OHCA in residential neighbourhoods vs nonresidential areas
- Outcome
- Interventions before ambulance arrival (CPR, AED attached, defibrillation) and 30-day survival
