Abstract：To analyze the changes in healthcare quality evaluation indicators for hospitalized tuberculosis
patients under the diagnosis⁃related group（DRG）payment system，this study conducted a retrospective analysis
using an interrupted time series regression model. The results showed that following the DRG implementation，
the total hospitalization costs，average per⁃day hospitalization costs，medication costs，number of prescribed
medication varieties，and length of hospital stay all significantly decreased. The intervention effect of DRG was
particularly notable among drug⁃resistant tuberculosis patients，with significant improvements in indicators of
healthcare resource utilization， service efficiency，and quality of care（P<0.05）. The adoption of the DRG
payment model has promoted healthcare institutions to transform their service delivery models and alleviated the
financial burden on patients.
