Abstract: Objective　COVID-19 exerts a huge impact on health services. The current study aimed to provide the data of impact of COVID-19 on the number and proportion of outpatients in the pediatric internal medicine clinic of a tertiary hospital. Methods　This cross-sectional study investigated the impact of the COVID-19 pandemic on the number and proportion of total hospital outpatients, pediatric internal department outpatients, and the top three clinics of pediatric internal department outpatients (pediatric internal general clinic, respiratory clinic, and digestive clinic) in Guangzhou Women and Children's Medical Center from January to April 2020, which were compared with those from January to April 2019. Independent sample t test and χ² test were used for statistical analysis. Results　Compared to the data during the same period in 2019, the number and the proportions of total hospital outpatients, pediatric internal department outpatients, pediatric internal general clinic, pediatric respiratory clinic, pediatric digestive clinic were significantly decreased (all P<0.05). The proportion of pediatric internal medicine department outpatients decreased from 47.92%-52.27% in 2019 to 20.74%-30.56% in 2020 (P<0.01). Conclusions　The number of total hospital outpatients, pediatric internal department outpatients, pediatric internal general clinic, pediatric internal respiratory clinic, and pediatric internal digestive clinic, and the corresponding proportions were decreased after the outbreak of COVID-19. These results might be related to promoting less gathering, keeping a certain social distance, less going out, wearing masks while going out, and frequent hand-washing, which is valuable for management decision-making and clinical measures.

摘要： 目的　新型冠状病毒肺炎（COVID-19）正在对卫生服务产生巨大影响。我们的目的是提供关于COVID-19对一家三级甲等医院儿内科门诊量及比例影响的数据。方法　本研究为横断面研究。对广州市妇女儿童医疗中心2020年1—4月COVID-19疫情对总门诊量、儿内科部门诊量、儿内科部门诊量排名前3位的儿内科普通门诊、呼吸门诊、消化门诊量和比例的影响，与2019年1—4月进行比较。统计学方法采用独立样本t检验、χ²检验。结果　与2019年同期对比，2020年2—4月总门诊量、儿内科部门诊量及儿内科普通门诊、呼吸门诊、消化门诊月门诊量和比例均显著降低（均P<0.05）；儿内科部门诊量比例由2019年的47.92%～52.27%下降为2020年的20.74%～30.56%（P<0.01）。结论　COVID-19疫情下总门诊量、儿内科部门诊量及儿内科普通门诊、呼吸门诊、消化门诊量和比例均下降，这些结果可能与提倡少聚集、保持一定的社交距离、少出门、出门戴口罩、勤洗手有关。
