Phased study on the impact of diagnosis-intervention packet payment on hospitalization expenses / 中华医院管理杂志

ABSTRACT

Objective:To explore the change trend of average hospitalization expense and cost structure of inpatients after the implementation of diagnosis-intervention packet (DIP) payment reform in Zhuhai.Methods:The data of hospitalization expense and the proportion of each classification cost (i.e. the value of a classification cost per thousand yuan of medical cost) in Zhuhai before and after the reform were analyzed by interrupted time series method, and the changes of per capita hospitalization cost and cost structure were studied.Results:The average hospitalization expense showed a linear change trend before and after the reform, and the immediate level and the slope of regression line did not change significantly after the reform, which was basically consistent with the trend before the reform. After the implementation of DIP, the proportion of various categories of expenses changed. Among them, the proportion of comprehensive medical services, treatment, traditional Chinese medicine, western medicine, blood and blood products, and other categories changed significantly, P values were less than 0.05. There was no obvious change in the proportion of expenses of diagnosis, rehabilitation and traditional Chinese medicine, but there was a change in the immediate level. The change in the level of diagnosis was -13.649 ( P< 0.001), the change in the level of rehabilitation was -1.053 ( P< 0.001), and the change in the level of traditional Chinese medicine was 2.781 ( P< 0.001). The immediate level and trend change of the proportion of consumables after the reform was not obvious. Conclusions:After the implementation of DIP payment in Zhuhai, the average expense of inpatients has not changed significantly, but the expense structure has changed significantly.
