摘要

Objectives: The objective was to compare the survival outcomes of emergency medical services (EMS)-witnessed to bystander-witnessed, and unwitnessed out-of-hospital cardiac arrests (OHCA) in Singapore. Secondary aims are to describe the 5-year trend in survival rates of EMS-witnessed arrests. Methods: This was a retrospective analysis of the Singapore?s OHCA registry data from 2011 to 2015. Excluded from the analysis were patients younger than 18 years old, arrests of traumatic etiology, resuscitation not attempted, and cases not conveyed by EMS. The primary outcome was survival to hospital discharge or 30 days post-arrest. Secondary outcomes were return of spontaneous circulation (ROSC) and survival to hospital admission. Results: 8,394 cases were analyzed, with 650 (7.7%) EMS-witnessed arrests, 4480 (53.4%) bystander-witnessed arrests, and 3264 (38.9%) unwitnessed arrests. Among EMS-witnessed arrests, the majority were presumed to be of cardiac etiology (62.8%) and the most common presenting rhythm was pulseless electrical activity (PEA; 57.2%). Survival to discharge or 30(th) day post-arrest was higher in EMS-witnessed arrests compared to bystander-witnessed and unwitnessed arrests (11.2% vs. 5.3% and 1.3%, p?
