BACKGROUND
Over 100,000 patients are diagnosed every year as out-of-hospital cardiac arrest (OHCA) cases in Japan and their number has continued to rise for the last decade, presenting a challenge for preventive public health research as well as emergency medical care. The purpose of this study was to identify whether there are any temporal patterns in daily OHCA presentations in Japan.
METHODS
Records of OHCA patients (n=701,651) transported by ambulance over the course of six years (1st January 2005 to 10th March 2011) in Japan were obtained from the All-Japan Utstein registry data of cardiopulmonary arrest patients. Time periods within which the incidence of OHCA significantly increased were identified by a temporal cluster detection test using scan statistics. The risk ratios of OHCA for the detected periods were calculated and adjusted according to a Poisson regression model accounting for effects of other factors.
RESULTS
The risk of OHCA significantly rises 1.3-1.6 times around New Year's Day in Japan.
CONCLUSIONS
Our analysis revealed the increased daily incidence of OHCA around every New Year's Day in Japan.
背景
在日本，每年有超过10万名患者被诊断为院外心脏骤停（OHCA）病例，且在过去十年中其数量持续上升，这给预防性公共卫生研究以及紧急医疗护理带来了挑战。本研究的目的是确定日本每日OHCA病例数是否存在任何时间模式。
方法
从全日本心肺骤停患者Utstein登记数据中获取了2005年1月1日至2011年3月10日六年间由救护车运送的OHCA患者（n = 701,651）的记录。使用扫描统计的时间聚类检测试验确定OHCA发病率显著增加的时间段。根据考虑其他因素影响的泊松回归模型计算并调整检测时间段内OHCA的风险比。
结果
在日本，元旦前后OHCA的风险显著上升1.3至1.6倍。
结论
我们的分析揭示了日本每年元旦前后OHCA每日发病率的增加。
