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.
