Abstract 299: Out-of-Hospital Cardiac Arrest: A 25 Years Registry
2018
Introduction: For many years, organizations like American Heart Association (AHA) published guidelines for the management of Out-of-Hospital Cardiac Arrest (OHCA). Our Emergency Medical Service (EMS), in a catchment of 500,000 inhabitants, has registered all OHCA since 1993. The aim of this study was to describe evolution of the on scene return of spontaneous circulation (ROSC) after OHCA from cardio-vascular cause (CV) over the past years. Methods: Data were collected from an EMS registry since 1993. The study included adult patients with OHCA from CV. Collected data were evolution (death or ROSC), gender, age group (older than 15) and periods (1993-1999, 2000-2004, 2005-2009, 2010-2014, 2015-2017). The primary outcome was rate of on scene ROSC. Comparisons were performed with Chi-2 test and logistic regression. Results: The registry included 8761 adults with OHCA, 7165 (82.2%) of which had a CV. Mean age was 71.6 years old (SD 16.9), 58.7% were male. ROSC rate was 15.2%. ROSC increased from 10.3% before...
