目的 构建高龄老人“一键呼”救治平台，并评价其应用效果。方法 该平台包括医护端和用户端两个端口。研究团队为高龄老人建立健康档案并录入医护端数据库。用户通过拨打“120”或使用微信小程序呼叫，医护端自动获取健康档案。从医护端调取2023年1月1日—12月31日高龄老人使用该平台的院前调度时间、院前响应时间、患者满意度及医护人员满意度，与2022年1月1日—11月30日院前急救数据对比，以评价该平台应用效果。结果 截至2023年12月31日，已为1.1万例高龄老人建立健康档案，其中7 700例高龄老人使用了该平台。院前调度时间为（28.25±6.27） s，较传统院前调度时间（58.43±11.27） s显著缩短，差异有统计学意义（t=200.532，P<0.001）；院前响应时间为（9.26±1.93） min，较传统院前响应时间（10.98±2.41） min缩短，差异有统计学意义（t=47.785，P<0.001）。此外，7 577例（98.40%）患者对该平台表示满意，且未发生投诉及不良事件；114例（98.28%）医护人员对该平台表现出高度认可。结论 高龄老人“一键呼”救治平台能够缩短院前调度时间和响应时间，并提高患者及医护人员满意度。

Objective To construct the “one-click call” treatment platform for people in advanced age and evaluate its application effect. Methods The platform includes two ports，the medical terminal and the user terminal. The research team established health records for the oldest old and entered them into the doctor-nurse database. Medical terminal can automatically obtain health records when users dialed 120 or used wechat mini program. The pre-hospital scheduling time，pre-hospital response time，patient satisfaction and medical staff satisfaction using the platform from January 1 to December 31，2023 were collected from the medical terminal，and compared with the pre-hospital emergency data from January 1 to November 30，2022，to evaluate the application effect of the platform. Results By December 31，2023，health records of 11 000 people in advanced age had been established，and 7 700 of them had used the platform. The pre-hospital scheduling time was（28.25±6.27） s，which was significantly shorter than the traditional pre-hospital scheduling time（58.43±11.27） s，and the difference was statistically significant（t=200.532，P<0.001）. The pre-hospital response time was（9.26±1.93） min，which was shorter than the traditional pre-hospital response time（10.98±2.41） min，and the difference was statistically significant（t=47.785，P<0.001）. In addition，7 577 patients（98.40%） were satisfied with the platform，and no complaints or adverse events occurred. A total of 114 medical staff（98.28%） showed a high degree of satisfaction with the platform. Conclusion The "one-click call" treatment platform for the people in advanced age can shorten the pre-hospital scheduling time and response time，and improve the satisfaction of patients and medical staff，which has certain reference and promotion value.
