新加坡myResponder是由新加坡民防部队（SCDF）开发的一款新型智能手机应用程序，它可以通知志愿第一响应者疑似院外心脏骤停（OHCA）病例和附近自动体外除颤器（AED）的位置，以便他们协助复苏。我们的目的是研究这个应用程序的性能、遇到的挑战和未来的方向。方法：我们分析了myResponder应用程序自2015年4月至2019年7月推出以来的数据。审查了安装数量、已注册的社区第一响应者、疑似OHCA病例、应用程序发送的通知、接受激活并到达现场的响应者的百分比。在随后的试点项目中，还分析了携带AED的出租车驾驶应答者亚组（响应半径在1.5公里以内）。结果：截至2019年7月，myResponder应用程序中注册了46,689名响应者。总共创建了19,189例疑似OHCA病例，中位数为每月358例（IQR 330-430），其中10,073名响应者接受myResponder的激活，4,955名响应者到达现场。针对这些病例共发送了135,599份通知，中位数为每例7.1份通知（IQR 4.3-8.7）。2019年，接受通知并到达现场的响应者比例分别为45.8%和24.1%。43%（1110/2581）的应答者在EMS工作人员之前到达。结论：myResponder移动应用程序是一种可行的智能技术解决方案，可以提高社区对OHCA的反应，并增加旁观者心肺复苏和AED的使用。未来的方向包括增加活跃响应者的数量，提高响应率，应用程序性能，以及更好的数据捕获以提高质量。
Objective The Singapore myResponder is a novel smartphone application developed by the Singapore Civil Defence Force (SCDF) that notifies volunteer first responders of a suspected out-of-hospital cardiac arrest (OHCA) case and locations of Automated External Defibrillators (AED) in the vicinity so that they can assist with resuscitation. We aimed to examine the performance of this application, challenges encountered, and future directions.Methods:We analyzed data from the myResponder app since its launch from April 2015 to July 2019. The number of installations, registered community first responders, suspected OHCA cases, notifications sent by the app, percentage of responders who accepted activation and arrived at scene were reviewed. A subgroup of taxi driving responders (within a 1.5-kilometer response radius) carrying an AED under a subsequent pilot program was also analyzed.Results:By July 2019, 46,689 responders were registered in the myResponder app. There were a total of 19,189 cases created for suspected OHCA, with a median of 358 cases per month (IQR 330-430), in which 10,073 responders accepted activation from myResponder and 4,955 arrived on-scene. A total of 135,599 notifications were sent for these cases, with a median of 7.1 notifications per case (IQR 4.3-8.7). In 2019, the percentages of responders who accepted notification and arrived on scene were 45.8% and 24.1%, respectively. 43% (1110/2581) of responders arrived before EMS crew.Conclusion:The myResponder mobile application is a feasible smart technology solution to improve community response to OHCA, and to increase bystander CPR and AED use. Future directions include increasing the number of active responders, improving response rates, app performance, and better data capture for quality improvement.
