在紧急医疗服务（EMS）提供者到达现场之前使用自动体外除颤器（aed）可以增加院外心脏骤停（OHCA）后的存活率。放置在公共场所的除颤器可能在需要时无法随时使用。我们描述了一种AED监测协议，该协议通过时间和空间跟踪这些设备，以改善公众健康和生存，并促进研究。在公共场所安装有自动除颤器，供非专业人士在急救人员到达现场之前治疗OHCA患者。OHCA病例包括由有组织的EMS人员评估并治疗OHCA的患者。每年登记10000个aed将使使用准备情况的估计精度达到0.4%。每年入组2500例患者，到出院的生存率估计精度为1.9%。招聘于2014年3月21日开始，目前正在进行中。aed是通过多种方法发现的。然后，每个AED都贴上一个标签，该标签是一个唯一的二维矩阵代码；使用智能手机记录二维矩阵代码，并跟踪AED的位置和状态；这些元素通过互联网自动实时传递到一个安全机密的数据库。当二维矩阵代码被重新扫描用于任何非临床或临床使用AED时，用户被要求回答一组关于设备状态的有限问题。任何临床使用AED的主要结局是存活到出院。对结果进行了描述性总结。这些活动是根据食品和药物管理局授予的公共卫生监督权力进行的。定期向参与地点和赞助者提供结果，以改善公共卫生和护理质量。
Lay use of automated external defibrillators (AEDs) before the arrival of emergency medical services (EMS) providers on scene increases survival after out-of-hospital cardiac arrest (OHCA). AEDs have been placed in public locations may be not ready for use when needed. We describe a protocol for AED surveillance that tracks these devices through time and space to improve public health, and survival as well as facilitate research. Included AEDs are installed in public locations for use by laypersons to treat patients with OHCA before the arrival of EMS providers on scene. Included cases of OHCA are patients evaluated by organised EMS personnel and treated for OHCA. Enrolment of 10 000 AEDs annually will yield precision of 0.4% in the estimate of readiness for use. Enrolment of 2500 patients annually will yield precision of 1.9% in the estimate of survival to hospital discharge. Recruitment began on 21 Mar 2014 and is ongoing. AEDs are found by using multiple methods. Each AED is then tagged with a label which is a unique two-dimensional (2D) matrix code; the 2D matrix code is recorded and the location and status of the AED tracked using a smartphone; these elements are automatically passed via the internet to a secure and confidential database in real time. Whenever the 2D matrix code is rescanned for any non-clinical or clinical use of an AED, the user is queried to answer a finite set of questions about the device status. The primary outcome of any clinical use of an AED is survival to hospital discharge. Results are summarised descriptively. These activities are conducted under a grant of authority for public health surveillance from the Food and Drug Administration. Results are provided periodically to participating sites and sponsors to improve public health and quality of care.
