RESUMO
Objective:To analyze the effect of the implementation of diagnosis-intervention packet (DIP) on the doctors′ diagnosis and treatment behavior of chronic diseases, so as to provide reference for further improving medical insurance payment related policies.Methods:The first page information of chronic disease patients admitted to hospitals with diabetes, hypertension and coronary atherosclerotic heart disease as the main conditions in 103 hospitals at all levels and township health centers in a city from 2016 to 2020 was collected, and the patients were divided into non-DIP group and DIP group according to the implementation time of DIP. After 1∶1 propensity score matching to balance the general conditions of the 2 groups, the diagnosis and treatment behaviors were analyzed from two dimensions: diagnostic behavior and treatment behavior. The grade A rate of medical record writing, admission and discharge diagnosis coincidence rate, and the average length of stay were used to evaluate the diagnostic behavior; the proportion of drugs and the degree of change in the cost structure were used as the evaluation indicators of treatment behavior.Results:After matching, 41 050 patients were included in both the non-DIP group and the DIP group.From the perspective of diagnostic behavior, the grade A rate of medical record writing in the non-DIP group and the DIP group was 99.40% and 99.83%, the coincidence rate of admission and discharge diagnosis was 58.42% and 61.79%, the average hospital stay was 8.03 days and 7.04 days respectively, and the difference between the groups was significant ( P<0.05). From the view of treatment behavior, the proportion of drugs decreased from 33.00% in the non-DIP group to 27.59% in the DIP group, with a significant difference ( P<0.05); the drug cost represented by Western medicine changed negatively, while the diagnostic cost showed a positive change. Conclusions:DIP has played a certain role in regulating doctors′ diagnosis and treatment behavior for chronic diseases. Among them, doctors have significantly improved their diagnostic behavior for chronic diseases, and the proportion of drugs in treatment behavior has been well controlled.
RESUMO
Objective To analyze the impact of the comprehensive reform of public hospitals in Tianjin on the cost structure of inpatients at a tertiary general hospital.Methods Homepage data of the medical records from January 2015 to June 2018 were selected from a tertiary general hospital in Tianjin.The Beijing version of diagnosis related groupings(BJ-DRGs) was used to compare the expense structure of these inpatients before and after such a reform.Wilcoxon signed rank sum test,Z test and Pearson correlation analysis were performed for each index.Results Since the reform,the number of hospital discharges and that of DRGs had remained basically stable,while the case mixed index(CMI) weight increased slightly(from 1.0065 to 1.0386);the total hospitalization expenses,medical expenses,nursing expenses,management expenses and consumables expenses had increased.On the other hand,the expenses of medication and medical technology decreased,and the differences of these expenses were statistically significant (P ＜0.05).The time consumption index (0.87) and drug consumption index (0.80) were always lower than average,but the cost consumption index (1.38) remains above average with a slight rise.Conclusions The reform of public hospitals in Tianjin has encouraged such hospitals to improve their service procedures by adjusting such measures as pricing of medical services,and promoted their proactive management of hospitals.Hence the initial goal of "controlling costs,adjusting structure,and reducing costs" has been met.However,cost rise control still deserves major attention.
