Abstract 333: Sudden Death Expertise Center: A Sudden Cardiac Arrest (SCA) Registry

Introduction - Knowledge of the epidemiology of the SCA is scarce, requiring collaboration of Emergency Medical Services and Intensive Care Units. Thus we developed a Sudden Death Expertise Center which first step was to develop a exhaustive register. Methods - We considered cases from a large ongoing population-based register, conducted in Paris and suburbs (population of 6.6 millions). Using multiple-source and central adjudication, we prospectively enrolled all out-of-hospital cardiac arrests since May 2011. Sources are fire departments (BLS), Mobile intensive care ambulance (ALS) and hospital services (Emergency, Intensive Care, Cardiology). Completeness is ascertained through informatic queries in some hospitals. Results - Over the first 8 months, we reported 2,214 out-of-hospital cardiac arrests, including 1449 with resuscitation attempted and 1193 with presumed cardiac cause (Figure 1). Among them, mean age was 64.5 years, and they occurred at home in 826 case (72.2%). Initial shockable rhythm was reported in 186 cases (16.2%), and 375 patients (31%) were admitted to hospital. Coronary angiography was performed in 198 patients (53%) and therapeutic hypothermia was applied in 192 patients (51%). Survival at discharge was 3,1% considering all OHCA, and 5,7% for SCA when the resuscitation was attempted. Completeness of the registry was 93%. Conclusion - This registry allow a better understanding of epidemiology of SCA. The next step is the establishment of a multidisciplinary approach to improve survival, through prevention (education programs), treatments (AED programs), and familial screening.
