This study aimed to evaluate the impact of the diagnosis-Intervention Package (DIP) payment method on medical quality and inpatient burden for Urban Employee Basic Medical Insurance (UEBMI) and Urban and Rural Residents Basic Medical Insurance (URRBMI) enrollees in Southwest China. A multiple-group interrupted time series analysis was conducted on 180,071 inpatient reimbursement records from 2019 -2021.Results showed that after DIP implementation, the average length of stay decreased for both UEBMI and URRBMI inpatients, while the number of admissions, average hospitalization costs, and actual compensation ratios increased. There were significant differences in the impact of DIP on different age groups. These findings provide insights into the effectiveness of the DIP payment reform and offer implications for healthcare policy -making.
