Study on the Inpatient Cost Structure of DRG Overrun Cases in a Certain Grade A Tertiary Specialized Hospital
Objective:This study aims to analyze the composition and variation patterns of DRG overrun cases in a certain grade A tertiary specialty hospital in Tianjin City,to provide a basis for optimizing hospital cost structure,improving management efficiency,and controlling costs.Methods:The subjects of the study were the top 15 DRG groups with the highest average overrun amounts in 2023.The structural variation method was used to analyze the factors affecting costs,and grey relational analysis was employed to eval-uate the correlation between each cost component and the total hospitalization costs.Results:Out of 7 840 cases,2 822 DRG overrun cases were selected(accounting for 35.99%),primarily concentrated in the RG13,ES31,HR11,EX23,and EX21 groups.The main costs included medication,imaging tests,laboratory tests,and treatment fees,with varying structural differences and impacts on hospi-talization costs between overrun and normal cases.Grey relational analysis revealed that imaging and laboratory fees had the strongest correlation with total costs in 11 DRG groups,medication fees had the strongest correlation in 3 groups,and bed fees had the strongest correlation in 1 group.Conclusion:By adjusting the costs of imaging tests,laboratory tests,medications,and treatments,hospital costs can be effectively controlled,patient hospitalization expenses can be reduced,and the utilization of medical insurance funds can be op-timized,achieving a win-win situation for hospitals,patients,and medical insurance funds.
