Overview

Interrupted time series analysis reveals limited effects of DRG payment reform on healthcare expenditure for lung cancer inpatients, indicating structural cost shifts in diagnostic and pharmaceutical areas.

Key Points

  • DRG payment reform showed limited immediate effects on total hospitalization costs for lung cancer inpatients.
  • Significant increases in diagnostic expenses (+¥1,953.74) and drug costs (+¥4,963.67) were identified post-reform.
  • Utilizing interrupted time series analysis, the study evaluated data from 1,076 lung cancer inpatients between 2019 and 2023.
  • Findings point to potential distortions in clinical practices due to rising expenses in drugs and diagnostics, affecting treatment efficiency.
