Abstract Aim Cardiac arrest centers have been associated with improved outcome for patients after cardiac arrest. Aim of this study was to investigate the effect on outcome depending on admission to high-, medium- or low volume centers. Methods Analysis from a prospective, multicenter registry for out of hospital cardiac arrest patients treated by the emergency medical service of Vienna, Austria. The frequency of cardiac arrest patients admitted per center/year (low <50; medium 50–100; high >100) was correlated to favorable outcome (30-day survival with cerebral performance category of 1 or 2). Results Out of 2238 patients (years 2013–2015) with emergency medical service resuscitation, 861 (32% female, age 64 (51;73) years) were admitted to 7 different centers. Favorable outcome was achieved in 267 patients (31%). Survivors were younger (58 vs. 66 years; p < 0.001), showed shockable initial heart rhythm more frequently (72 vs. 35%; p < 0.001), had shorter CPR durations (22 vs. 29 min; p < 0.001) and were more likely to be treated in a high frequency center (OR 1.6; CI: 1.2–2.1; p = 0.001). In multivariate analysis, age below 65 years (OR 15; CI: 3.3–271.4; p = 0.001), shockable initial heart rhythm (OR 10.1; CI: 2.4–42.6; p = 0.002), immediate bystander or emergency medical service CPR (OR 11.2; CI: 1.4–93.3; p = 0.025) and admission to a center with a frequency of >100 OHCA patients/year (OR 5.2; CI: 1.2–21.7; p = 0.025) was associated with favorable outcome. Conclusions High frequency of post-cardiac arrest treatment in a specialized center seems to be an independent predictor for favorable outcome in an unselected population of patients after out of hospital cardiac arrest.
