An Empirical Study of Payment by DRG for Rehabilitation Cases Based on the PSM-DID Model
Objective Explore the impact of payment by DRG on rehabilitation cases,evaluate the effect of DRG policy reform for rehabilitation cases and make relevant recommendations.Methods Rehabilitation cases admitted to designated medical institutions in Sichuan Province in 2020-2021 were extracted,and regression analyses were per-formed after Propensity Score Matching using the Difference in Differences method to evaluate the impact of DRG payment on the inpatient costs and the hospitalization days of rehabilitation cases,then analyze the net effect of the policy.Results After the implementation of DRG payment,the total hospitalization cost,drug cost,treatment cost,and examination cost of rehabilitation cases decreased to different degrees,and only the bed cost increased,in which the total hospitalization cost decreased by 21.8％(P＜0.05),and the cost structure of the cases changed to a certain extent compared with that before the implementation of DRG payment.In addition,the number of hospi-talization days for rehabilitation cases has not been effectively reduced under the DRG policy,but rather increased by 13.4％(P＜0.05).Conclusion DRG payment can effectively reduce the financial burden of rehabilitation cases,but it does not optimize the operational efficiency of hospitals.Whether payment by DRG is applicable to rehabilita-tion cases is open to further discussion,the health insurance department and hospitals should be in close contact to actively explore new modes of health insurance payment for rehabilitation cases.
