Abstract:Objective：To use DRG key indicators to parity medical service performance and provide reference for hospital fine management. Methods：The DRG medical data of 16 pilot hospitals （including our hospital）from 2020 to 2022 were extracted from the medical insurance DRG data management platform，and the medical capacity and service efficiency were evaluated and analyzed from the aspects of the number of DRG groups，the number of DRG groups，the CMI value，the time consumption index and the cost consumption index. Results：The CMI value and the number of DRG groups of our hospital in 2022 were higher than the average number of 16 pilot hospitals，which was also higher than that in 2020 and 2021. The cost consumption index was lower than the average of 16 pilot hospitals，while the time consumption index was greater than 1.0，which was higher than the average of 16 pilot hospitals. Conclusion：In 2022，the CMI value of DRG in our hospital needs to be further improved compared with that of grade A tertiary general hospitals，and it is also necessary to strengthen the control of time consumption index and shorten the average length of hospitalization.DRG related key indicators can objectively reflect the advantages and disadvantages of hospital medical service ability，and can provide reference for continuous improvement of medical service.
