2019年12月至今，新型冠状病毒肺炎（coronavirus disease 2019，COVID-19）疫情已经发展至全球。通过一系列防控措施，我国疫情已经得到基本控制；但其他国家和地区发病人数、死亡人数仍在快速上升。应对如此重大的疫情，医院的应急管理体系受到了严峻考验，尤其是医院的急诊科承担了发热患者筛查诊断及普通患者的急诊急救。上海交通大学医学院附属瑞金医院经过2个月左右的实践探索，在应急管理制度完善、平战结合机制建立、医疗资源重组、物资调配保障、信息系统优化等方面总结了一些经验，实现医务人员“零感染”，COVID-19患者“零漏诊”和“零交叉感染”的目标。

Since December 2019, the coronavirus disease 2019 (COVID-19) has become one of the most significant infectious diseases in the world. The epidemic in China has been basically controlled through a series of prevention and control measures. But the number of confirmed cases and deaths in other countries and regions is still rapidly rising. In response to this major epidemic, the hospitals emergency management system is facing a great challenge, especially the department of emergency, which takes the responsibilities of the screening and diagnosis of fever patients as well as the emergency treatment of ordinary patients. Through two months of practice and exploration, our hospital has summarized some experiences in improving the emergency management system, establishing a peace and war integration mechanism, reorganizing medical resources, guaranteeing the deployment of supplies and optimizing information system, and has achieved the "zero infection" of medical staff, "zero misdiagnosis" and "zero cross-infection" of patients with COVID-19.
