Abstract:
Objective To assess the impact of the"one hospital with multiple districts"model on the quality of care and operational efficiency of inpatient surgical services in a tertiary care general hospital.Methods With 2019(before reform)and 2023(after implementation)serving as the observation nodes,the branch hospital district was designated as the intervention group and the main hospital district was allocated tothe control group.An empirical analysis was conducted with the method of Difference-in-Differences(Dl D),and the model robustness was verified by parallel trend test and placebo test.Fourteen core indicators were selected from four dimensions:medical capability,safety management,service efficiency and cost control,to assess the effect.Results After the reform,the medical capabilityindicators and service efficiency indicators were significantly optimized(P＜0.1);the mortality rate,the infection rate in class l incisionand 7-day readmission rate in the safety management indicators were significantly reduced(P＜0.1),but the rate of complications of inpatients undergoing elective surgery was significantly increased(P=0.007);the average hospitalization expenses,the average drug expenses and the average consumable expenses in the cost control indicators were significantly reduced(P＜0.10),and the increase in the average surgery cost was not statistically significant(P=0.765).Conclusion The"one hospital with multiple districts"model has achieved economies of scale through the integration and allocation of resources,improving medical capacity and operational efficiency without negative impact on cost control.
