Impact of risk adjustment for drug-resistant types on tuberculosis patients’ outcomes under China’s innovative payment methods: a quasi-experimental study design

The DR-type risk adjustment policy under China's diagnosis-intervention packet system proved effective in optimizing resource use and enhancing efficiency, particularly for DS-TB patients, while preserving care quality for DR-TB patients. These findings demonstrate the value of tailored risk adjustment within payment frameworks for heterogeneous diseases like tuberculosis, providing crucial evidence for optimizing TB care and implementing effective payment reforms in China and similar settings.
