The profile of Japanese Association for Acute Medicine - out-of-hospital cardiac arrest registry in 2014-2015.

Abstract

AimTo describe the registry design of the Japanese Association for Acute Medicine – out‐of‐hospital cardiac arrest (JAAM‐OHCA) Registry as well as its profile on hospital information, patient and emergency medical service characteristics, and in‐hospital procedures and outcomes among patients with OHCA who were transported to the participating institutions.MethodsThe special committee aiming to improve the survival after OHCA by providing evidence‐based therapeutic strategies and emergency medical systems from the JAAM has launched a multicenter, prospective registry that enrolled OHCA patients who were transported to critical care medical centers or hospitals with an emergency care department. The primary outcome was a favorable neurological status 1 month after OHCA.ResultsBetween June 2014 and December 2015, a total of 12,024 eligible patients with OHCA were registered in 73 participating institutions. The mean age of the patients was 69.2 years, and 61.0% of them were male. The first documented shockable rhythm on arrival of emergency medical services was 9.0%. After hospital arrival, 9.4% underwent defibrillation, 68.9% tracheal intubation, 3.7% extracorporeal cardiopulmonary resuscitation, 3.0% intra‐aortic balloon pumping, 6.4% coronary angiography, 3.0% percutaneous coronary intervention, 6.4% targeted temperature management, and 81.1% adrenaline administration. The proportion of cerebral performance category 1 or 2 at 1 month after OHCA was 3.9% among adult patients and 5.5% among pediatric patients.ConclusionsThe special committee of the JAAM launched the JAAM‐OHCA Registry in June 2014 and continuously gathers data on OHCA patients. This registry can provide valuable information to establish appropriate therapeutic strategies for OHCA patients in the near future.
