摘要快速反应系统(RRS)在欧美、澳洲等发达国家医疗机构的普遍开展和应用，使院内患者临床不良事件(心搏骤停、意外死亡等)得到减少和改善，同时降低了医院患者ICU入住率及死亡率，从而缩短了患者的住院时间、减少了医疗费用。然而，RRS在我国仍处在探索阶段。因此，本文就RRS的模式及应用发展情况进行相关阐述。

abstractsBecause of the widespread development and application of rapid response system (RRS) in medical institutions in developed countries, such as Europe, America and Australia, the clinical adverse events (cardiac arrest, accidental death, etc.) in hospital patients have been reduced and improved. Meanwhile, the hospitalization rate and mortality rate of intensive care unit in hospital patients have been reduced, thus shortening the hospitalization time and reducing the medical expenses. Nevertheless, RRS is still in the exploration stage in our country. Therefore, the article reviews the RRS model and application development.
