RESUMO
Objective:To analyze the changes of hospitalization rates in different regions, medical institutions and populations in China from 2009 to 2019, so as to provide reference for the country to make relevant decisions.Methods:The data of China′s health statistical yearbook from 2009 to 2019 were obtained, and the changes of hospitalization rate and the number of hospitalizations per 100 outpatient and emergency admissions in different regions and medical institutions, and hospitalization rate of different populations and different diseases were analyzed. Descriptive analysis and frequency analysis were used.Results:The hospitalization rate in China continued to rise, from 9.95% in 2009 to 19.03% in 2019. Among them, the hospitalization rate in the eastern, central and western regions increased from 9.7%, 9.9% and 10.8% to 17.0%, 19.3% and 21.5% respectively, with an average annual growth rate of 5.8%, 6.9% and 7.1% respectively. The number of inpatients in public hospitals increased by 1.2 times and that in private hospitals increased by 4.5 times. The number of inpatients in tertiary, secondary and primary hospitals and primary medical institutions increased by 292.9%, 80.8%, 166.4% and 4.5% respectively.From 2009 to 2018, the number of hospitalizations per 100 outpatient and emergency admissions in the hospital increased from 4.5 to 5.7, and decreased to 5.6 in 2019. The increase of hospitalization rate of urban residents was less than that of rural residents. The hospitalization rate of residents aged 0-4 and ≥55 years increased the fastest. In recent years, the discharge diseases were mainly common diseases, chronic diseases and frequently occurring diseases, including pneumonia, acute upper respiratory tract infection, diabetes, and hypertension.Conclusions:During the ten years of medical reform, the hospitalization rate in China has continued to rise, and the overall trend is reasonable. There are significant differences in the changes of hospitalization rates between urban and rural areas, regions and populations in China.
