分析"新型冠状病毒肺炎(COVID-19)"疫情影响下，急诊患者就诊特点的变化，探索未来急诊医疗需求的变化趋势，为急诊资源合理调配、急诊救治研究方向确立及医务人员培训等提供依据。

采用回顾性列队研究方法，比较南通市第一人民医院2019年1月至7月疫情前组和2020年1月至7月疫情期间组急诊患者数量、病种和病情分级构成、疫情前和疫情期间两组时间内护理人力资源分配数据的变化。

急诊患者总量疫情前组103 033例，疫情期间组68 575例。内科系统疾病就诊占比显著下降，外科系统疾病就诊比例显著上升(均P<0.001)。与疫情前组相比，疫情期间组内科系统中，呼吸系统、环境伤害疾病占比显著下降(均P<0.001)；外科系统中，泌尿系统、血管系统及外伤占比显著增加(均P<0.001)。一、二级患者中，疫情期间组内科系统疾病占比明显增加，而外科系统占比明显减少(P<0.05)，严重创伤疫情期间组占比下降明显(P<0.05)。疫情前组护理总班次6 177，疫情期间组护理总班次7 499。疫情期间预检班次比占显著增加(P<0.001)；助诊班次设置显著减少(P<0.001)。

COVID-19疫情下急诊患者就诊特点能反映本地区真正的急诊需求，仍以内科系统的呼吸、心血管、神经和消化系统专科以及外科的创伤救治为主要需求；对三级综合医院今后急诊专科发展、重点培训方向、人力资源调配和急诊大数据建设具有一定参考价值。

To analyze the changes of emergency patients’ visiting characteristics under the influence of "novel coronavirus-19(COVID-19)" epidemic, to explore the changing trend of emergency medical demand in the future, and to provide the basis for rational allocation of emergency resources, establishment of emergency treatment research direction and training of medical staff.

A retrospective cohort study method was used to compare the number of emergency patients, the composition of disease types and disease grades, and the changes of nursing human resource allocation data before and during the epidemic in Nantong First People’s Hospital from January to July 2019 to January to July 2020.

The total number of emergency patients was 103 033 before the epidemic and 68 575 during the epidemic. The proportion of visits for medical diseases decreased significantly, while that for surgical diseases increased significantly (all P<0.001). Compared with the pre-epidemic group, the proportion of respiratory diseases and environmental injuries in the internal medicine system of the epidemic group decreased significantly (all P<0.001). In the surgical system, urinary system, vascular system and trauma increased significantly (all P<0.001). Among the first and second grade patients, the proportion of diseases in the internal medicine system increased significantly during the epidemic period, while that in the surgical system decreased significantly (P<0.05), while that in the severe trauma during the epidemic decreased significantly (P<0.05). The total number of nursing shifts in the group before the epidemic was 6 177, and that in the group during the epidemic was 7 499. During the period, the frequency of pre-inspection of epidemic situation increased significantly (P<0.001); The number of visiting shifts was significantly reduced (P<0.001).

The characteristics of emergency patients under COVID-19 epidemic can reflect the real emergency needs in this area, and the main needs are respiratory, cardiovascular, neurological and digestive system specialties of internal medicine and surgical trauma treatment. It has certain reference value for the future development of emergency department, key training direction, human resource allocation and emergency big data construction in tertiary general hospitals.
