INTRODUCTION: Out-of-hospital @entity1167 is a global health care problem. Like other cities in the world, Hong Kong faces the impact of such events. This study is the first territory-wide investigation of the epidemiology and outcomes of out-of-hospital @entity1167 in Hong Kong. It is hoped that the findings can improve survival of @entity1 with @entity1167 . METHODS: This study was a retrospective analysis of the prospectively collected data on out-of-hospital @entity1167 managed by the emergency medical service from 1 August 2012 to 31 July 2013. The characteristics of @entity1 and cardiac arrests, @entity341 , and survival rates were reported with descriptive statistics. Predictors of 30-day survival were evaluated with logistic regression. RESULTS: A total of 5154 cases of out-of-hospital @entity1167 were analysed. The median age of @entity1 was 80 years. Most arrests occurred at the @entity1 's home. @entity2224 or @entity1165 was identified in 8.7% of @entity1 . The median time taken for the emergency services to reach the @entity1 was 9 minutes. The median time to first defibrillation was 12 minutes. Of note, 2.3% of @entity1 were alive at 30 days or survived to hospital discharge; 1.5% had a good neurological outcome. Location of arrest, initial electrocardiogram rhythm, and time to first defibrillation were independent predictors of survival at 30 days. CONCLUSION: The survival rate of out-of-hospital @entity1167 @entity1 in Hong Kong is low. Territory-wide public access defibrillation programme and cardiopulmonary resuscitation training may help improve survival.
