Objective: To evaluate the policy text of DRG payment reform in China, identify the core content and policy deviation, and provide theoretical support and decision-making basis for the optimization of DRG payment reform policy. Methods: Based on text mining and statistical analysis, the PMC index model is constructed to quantitatively evaluate the six representative DRG payment reform policies in China from 2019 to 2022. Results: Among these six policies, three are excellent and three are good. Conclusion: It is necessary to comprehensively consider the requirements of different policy areas, carry out various reforms related to the payment reform according to local conditions, different policy receptors and the actual situation in various regions. Policy-making departments should pay attention to policy incentives in policy formulation, fully mobilize the initiative of policy receptors to participate in DRG payment reform, and improve the efficiency of DRG payment reform.
