Abstract：Objective To establish an index system with DRG performance management to comprehensively evaluate the medical service performance of tertiary maternity hospitals in Zhejiang Province in 2019, and to analyze the existing problems of DRG performance management in a maternity hospital. Methods An index evaluation system with DRG performance management was established by combining AHP and entropy weight method. A grey correlation model was used to comprehensively evaluate DRG performances of 15 tertiary maternity and child hospitals in the province. Results The maternity hospital in Hangzhou ranked high comprehensively in the province, the score of the CMI value was high, and the level and ability of diagnosis and treatment of medical services were high. However, the hospitalization cost, the average medicine cost, and the material consumption were higher than those in other hospitals, and the hospital readmission rate was higher than the average level of the entire province, which affected the promotion of its comprehensive evaluation in the whole province. Conclusion The establishment of the index evaluation system by using the combination weight can fully reflect the importance of the index and the subjective will of the decision-maker, and has certain scientificity and applicability. It is suggested to adjust hospitalization cost results, establish medical cost monitoring, reduce drug operating expenses, and conduct real-time monitoring of readmission rate, eliminate the decomposition of hospitalization times, and reduce readmission rate on the premise of ensuring efficacy.
