Background Citizen responder programs are implemented worldwide to dispatch volunteer citizens to participate in out-of-hospital cardiac arrest resuscitation. However, the risk of injuries in relation to activation is largely unknown. We aimed to assess the risk of physical injury for dispatched citizen responders. Methods and Results Since September 2017, citizen responders have been activated through a smartphone application when located close to a suspected cardiac arrest in the Capital Region of Denmark. A survey was sent to all activated citizen responders, including a specific question about risk of acquiring an injury during activation. We included all surveys from September 1, 2017, to May 15, 2020. From May 15, 2019, to May 15, 2020, we followed up on all survey nonresponders by phone call, e-mail, or text messages to examine if nonresponders were at higher risk of severe or fatal injuries. In 1665 suspected out-of-hospital cardiac arrests, 9574 citizen responders were dispatched and 76.6% (7334) answered the question regarding physical injury. No injury was reported by 99.3% (7281) of the responders. Being at risk of physical injury was reported by 0.3% (24), whereas 0.4% (26) reported an injury (25 minor injuries and 1 severe injury [ankle fracture]). When following up on nonresponders (2472), we reached 99.1% (2449). No one reported acquired injuries, and only 1 reported being at risk of injury. Conclusions We found low risk of physical injury reported by volunteer citizen responders dispatched to out-of-hospital cardiac arrest. Risk of injury should be considered and monitored as a safety measure in citizen responder programs.
背景 公民响应者计划在全球范围内实施，以派遣志愿者参与院外心脏骤停复苏。然而，与激活相关的受伤风险在很大程度上尚不清楚。我们旨在评估派遣公民响应者受伤的风险。
方法和结果 自 2017 年 9 月以来，公民响应者通过智能手机应用程序在丹麦首都地区附近发现疑似心脏骤停时被激活。向所有激活的公民响应者发送了一份调查，其中包括一个关于在激活期间受伤风险的具体问题。我们包括了 2017 年 9 月 1 日至 2020 年 5 月 15 日的所有调查。从 2019 年 5 月 15 日至 2020 年 5 月 15 日，我们通过电话、电子邮件或短信对所有调查未回复者进行了随访，以检查未回复者是否有更高的严重或致命伤害风险。在 1665 例疑似院外心脏骤停中，派遣了 9574 名公民响应者，其中 76.6%（7334 人）回答了关于身体伤害的问题。99.3%（7281 人）的响应者未报告受伤。有 0.3%（24 人）报告有身体受伤的风险，0.4%（26 人）报告受伤（25 例轻伤和 1 例严重伤[踝关节骨折]）。在对未回复者（2472 人）进行随访时，我们联系到了 99.1%（2449 人）。没有人报告受伤，只有 1 人报告有受伤风险。
结论 我们发现，被派往院外心脏骤停的志愿公民响应者报告的身体伤害风险较低。在公民响应者计划中，应考虑并监测受伤风险作为一项安全措施。
