Abstract：
(1) Purpose: The ongoing COVID-19 pandemic has had an impact on mental health and the utilization of hospital-based inpatient mental health care worldwide. The aim of this study was to determine the impact of this pandemic on the utilization of this service in Shanghai by comparison with hospital-based health care records during the preceding 4 years. (2) Methods: The medical records were provided by the Shanghai Municipal Health Insurance Bureau. Diagnostic coding was based on International Classification of Diseases-10th revision (ICD-10), and inpatients with codes from F00 to F99 were examined. (3) Results: Inpatients were compared according to gender, age, pandemic stage, and type of mental disease. Utilization of psychiatric inpatient care in Shanghai during each of the four stages of the pandemic (1 January 2016 to 21 January 2020; 22 January 2020 to 9 February 2020; 10 February 2020 to 1 March 2020; 2 March 2020 to 31 July 2020) was analyzed. Before the lockdown, the utilization of psychiatric inpatient care had an overall upward trend; after the lockdown, the number of inpatients dropped sharply; as of 31 July 2020, it has not been restored. The utilization of this service for most types of mental disease declined rapidly during the pandemic; for vascular dementia (VAD, F01), it was relatively steady. The observed number of inpatient patients was about 51.07% lower than the predicted number in 2020. (4) Conclusions: The COVID-19 pandemic led to the implementation of prevention and control measures that reduced the utilization of psychiatric inpatient care in Shanghai. The use of inpatient services for categories F20-F29 had the greatest decline, and VAD (F01) had the smallest change during the pandemic. This service consequence of COVID-19 is apparent; to assure access to adequate service during a pandemic, health care professionals should pay close attention to changes in the utilization of different mental health services.
摘要：
（1）目的：持续的COVID-19大流行对全球精神卫生和医院住院精神卫生保健的利用产生了影响。这项研究的目的是通过与前4年医院的医疗保健记录进行比较，确定这种大流行对上海这项服务利用的影响。(2)方法:病案由上海市医保局提供。诊断编码基于国际疾病分类第10次修订(ICD-10)，并检查了代码从F00到F99的住院患者。(3)结果:住院患者按性别进行比较,年龄,大流行阶段，和精神疾病的类型。分析了在大流行的四个阶段（2016年1月1日至2020年1月21日；2020年1月22日至2020年2月9日；2020年2月10日至2020年3月1日；2020年3月2日至2020年7月31日）中的每个阶段中上海精神科住院护理的利用情况。在封锁之前,精神科住院护理的利用率总体呈上升趋势；封锁后，住院人数急剧下降；截至2020年7月31日，尚未恢复。在大流行期间，大多数类型的精神疾病对这项服务的利用迅速下降；对于血管性痴呆(VAD，F01),它相对稳定。观察到的住院患者人数比2020年的预测人数低约51.07%。（4）结论：COVID-19大流行导致预防和控制措施的实施，降低了上海精神科住院患者的使用。F20-F29类别住院服务的使用下降幅度最大，VAD（F01）在大流行期间变化最小。COVID-19的这一服务后果是显而易见的；为了确保在大流行期间获得足够的服务，医护人员应密切关注不同精神卫生服务利用的变化。
