Objective To conduct a statistical analysis of electronic medical records of all inpatients from 2015 to 2021 in a large comprehensive tertiary hospital in the Guangdong-Hong Kong-Macao Greater Bay Area.The impact of the COVID-19 pandemic was discussed,and reference data for the rational allocation of local medical resources were provided.Methods A to-tal of 345,855 inpatient cases from 2015 to 2021 were extracted from the hospital's medical record system.Descriptive statistics,interval estimation,chi-square tests,and linear correlation analyses were conducted based on the International Classification of Diseases and Related Health Problems(ICD)and the International Classification of Procedures in Medicine(ICPM).Results The overall scale of inpatient cases remained stable,with the majority of patients coming from the local area.There were fewer male patients than female patients,and in 2020,due to the impact of the COVID-19 pandemic,the number of inpatients de-creased by 23.03％compared to 2019.The main disease categories included digestive system diseases,circulatory system disea-ses,respiratory system diseases,tumors,genitourinary system diseases,and pregnancy,childbirth,and the puerperium.Respir-atory system diseases and pregnancy,childbirth,and the puerperium showed significant changes,with the former experiencing a 49.36％decrease in 2020 compared to 2019,and the latter declining annually after reaching a peak in 2017,with the total num-ber of cases in 2021 being less than half of the peak in 2017.The mean length of hospital stay decreased from 8.22 days in 2015 to 7.23 days in 2021,which was lower than the averages in Guangdong Province and nationwide.The mean length of hospital stay for malignant tumor patients was significantly higher than other categories,reaching 15.7 days from 2015 to 2021.The main sur-gical categories were digestive system surgeries and obstetric procedures,with obstetric procedures showing a linear correlation with pregnancy,childbirth,and the puerperium.Conclusion Active analysis of electronic medical record data should be con-ducted to adjust the resource allocation of various disciplines in a timely manner,thereby better meeting the medical needs of the population.The COVID-19 pandemic not only had a certain impact on normal medical order in 2020 but also affected people's li-festyles,thereby changing the composition of disease spectra,especially respiratory system diseases.Long-term effects remain to be further observed.
