Schools are an important location for improving OHCA outcome. But there are few data on out of hospital cardiac arrest (OHCA) in schools. This study aimed to show incidence and outcome of OHCA in schools, specifying location and activities.
We used the Korean nationwide OHCA registry from 2008 to 2014. OHCA victims were categorized regarding level of school. The average annual incidence of OHCA was calculated based on per 1000 schools. The epidemiological characteristics are analysed and location and activity at the time of arrest is further described. The outcome of OHCA victims were analysed.
511 OHCA occurred in school while 374 cases were cardiac origin, 125 cases were non-cardiac, and 12 cases were missing in information. Annual incidence was 5.72 per 1000 school while highest incidence was shown in university (11.02 per 1000 school). The majority of victims were male (84.1%), aged 19-64 (62.2%, median 44.75), either students (35.0%) or visitors (35.2%). Most victims had none shockable rhythms, did not received EMS defibrillation and were not witnessed arrests, while most received bystander CPR. A large proportion of arrests occurred at an outdoor campus (29.7%) or sports facility (28.8%), and the most frequent activity was exercise (30.7%). 100 patients (19.6%) survived to discharge, and 66 patients (12.9%) were discharged with good neurological outcome.
Incidence of OHCA in school is low. Most of victims were adult visitors. About one third of OHCA occurred during sports activity or at the sports facility.
学校是改善院外心脏骤停（OHCA）结局的重要场所。但关于学校院外心脏骤停的数据较少。本研究旨在展示学校OHCA的发生率和结局，明确其发生地点和活动情况。
我们使用了2008年至2014年韩国全国OHCA登记数据。OHCA受害者按学校级别分类。基于每1000所学校计算OHCA的年均发生率。分析流行病学特征，并进一步描述心脏骤停时的地点和活动情况。分析OHCA受害者的结局。
学校发生了511例OHCA，其中374例为心源型，125例为非心源型，12例信息缺失。每1000所学校的年发生率为5.72，其中大学发生率最高（每1000所学校为11.02）。大多数受害者为男性（84.1%），年龄在19 - 64岁之间（62.2%，中位数44.75），包括学生（35.0%）或访客（35.2%）。大多数受害者无可电击心律，未接受急诊医疗服务（EMS）除颤，且非目击心脏骤停，而大多数接受了旁观者心肺复苏（CPR）。很大一部分心脏骤停发生在校园户外（29.7%）或体育设施（28.8%），最常见的活动是锻炼（30.7%）。100例患者（19.6%）存活至出院，66例患者（12.9%）出院时神经功能良好。
学校OHCA的发生率较低。大多数受害者是成年访客。约三分之一的OHCA发生在体育活动期间或体育设施处。
