Abstract:
Objective To analyze the impact of the basic medical insurance outpatient mutual aid policy on the utilization of medical services.Methods Data indicators related to the utilization of medical services from a tertiary hospital in Wuhan,Hubei Province,from January 2022 to December 2023 were collected.Interrupted time series analysis was used to examine the changing trends of outpatient visits,hospitalizations,and average cost per outpatient visit before and after the implementation of the outpatient mutual aid policy.The Granger causality test and vector autoregressive model were also used to analyze the association between outpatient and inpatient services.Results The outpatient mutual aid policy significantly increased the number of outpatient visits,hospitalizations,and day surgeries in the sample medical institutions(P＜0.05),but had limited impact on the average cost per outpatient visit and hospitalization.Conclusion Outpatient mutual aid can effectively promote the utilization of outpatient services,but attention needs to be paid to potential moral hazard issues and strengthen the supervision of medical insurance funds.
