Objective To understand the trend and problems of asthma treatment in different levels of hospitals in Chongqing, and to provide objective basis for more refined and standardized asthma management. Methods The outpatient and inpatient asthma diagnosis and treatment data of four hospitals of different grades in Chongqing from 2017 to 2021 were extracted by medical big data capture platform, and the trend of outpatient and prescription changes was analyzed retrospectively according to natural year. Results There were 19514 outpatients asthma visits in the four hospitals, of whom 11816 (60.6%) were female. There were 1875 hospitalizations, of which 1117 (59.6%) were female. ① Changes of asthma visit mode: From 2017 to 2019, the number of outpatient asthma visits and the proportion of asthma in the total outpatient volume increased, decreased significantly in 2021, and basically recovered to the level of 2019 in 2022. Asthma hospitalizations in tertiary hospitals showed a decreasing trend, while those in secondary hospitals increased significantly. The proportion of asthma patients who chose outpatient treatment in the four hospitals increased year by year, among which the increase was more significant in non-tertiary teaching hospitals, and the proportion of asthma acute attack in outpatient and inpatient treatment increased. ② Changes of medication pattern: The rate of inhaled corticosteroids/long-acting β2-agonists (ICS/LABA) prescription in outpatient department increased year by year, the highest was 48.6%, but the rate of short-acting β2-agonists (SABA) prescription also increased year by year, especially in secondary hospitals, the rate of SABA prescription in secondary hospitals reached 39.7%. The proportion of hospitalized asthma patients treated with inhaled corticosteroids (85.1%) was higher than that of intravenous corticosteroids (50.9%), and the proportion of intravenous theophylline prescription was as high as 91.7%, while the proportion of nebulized SABA prescription was 71.4%. Conclusions The trend of asthma diagnosis and treatment is that the number of outpatients and the use of ICS/LABA is gradually increasing, while the number of inpatients is decreasing. However, there is still a large gap in the proportion of asthma maintenance medication used in different levels of hospitals, so it is necessary to continuously promote standardized diagnosis and treatment management of asthma in hospitals at all levels, especially primary hospitals.
