Abstract:Objective：To analyze the effect of DGR payment model on hospitalization costs of patients with colorectal cancer undergoing surgery in traditional Chinese medicine hospitals，and provide useful reference basis for further improving DRG reform plan. Methods：The hospital discharge data of colorectal cancer surgery cases in acertain grade A tertiary combined Chinese and Western medicine hospital in a certain city before and after DGR payment reform were collected. The differences in age，gender，hospitalization days，average cost per case，and other data between the two groups were statistically compared. Results：Compared with before the DRG payment reform，the average total cost per case of colorectal cancer surgery cases decreased from 54，017.67 yuan to 47，077.32 yuan，a decrease of 12.85% after the reform. The cost of Western medicine decreased significantly，and the costs for diagnostic and other categories also decreased to some extent. The structure of hospitalization costs of colorectal cancer surgery cases changed after the reform，with the proportion of Western medicine and other categories decreasing，while the proportion of material costs increased significantly，and the proportions of Chinese medicine treatment，surgical treatment，nursing，and Chinese medicine costs increased to some extent. The differences were statistically significant. Conclusion：The DRG payment mode has played a role in reducing the partial project cost expenditure of colorectal cancer cases in traditional Chinese medicine hospitals，thereby reducing the total hospitalization costs，and has certain representativeness.
