INTRODUCTION: There are substantial differences in long-term survival of patients resuscitated from out-of-hospital cardiac arrest, and the level of care during hospitalization may be a contributing factor. The purpose of this study was to determine if a difference in long-term prognosis between hospitals could be detected in patients surviving cardiac arrest in Copenhagen. MATERIAL AND METHODS: The mobile emergency care unit attempted resuscitation in 1,098 patients with out-of-hospital cardiac arrest in the period 2002 to 2006, among whom return of spontaneous circulation occurred in 336 (30%) of the patients admitted to hospital. Survival was determined using the Central Population Registry through Statistics Denmark. RESULTS: Patients admitted to a tertiary facility were younger, more frequently male, they had more commonly ventricular fibrillation/pulseless ventricular tachycardia (VF/pVT) as their initial rhythm, and they had more frequently received bystander cardiopulmonary resuscitation. Survival at 4.6 years was 41% in patients admitted to the tertiary hospital and 10% in patients admitted to other hospitals, p
