Interrupted time series analysis reveals a decrease in medical costs and shifts in cost structure for inpatient care post-DIP reform.

Total inpatient costs reduced by 3.42% for surgical and 1.25% for non-surgical groups after DIP introduction.
Drug costs significantly lowered (surgical group: β3 = −5.50; non-surgical group: β3 = −4.11), indicating a structural shift in expenses.
Analysis employed interrupted time series methods to evaluate changes in costs from 2019 to 2023.
Increases in consumable and inspection costs highlight areas for future cost management.

Chenxuan et al. (2025) studied this question.
