Abstract:
Objective:With Diagnosis related groups(DRG)indicator introduced into the hospital efficiency evaluation, to analyze the adjustment effect of DRG on the efficiency value, and to compare the similarities and differences between the DEA efficiency value and the DRG efficiency indicator.Methods:The DRG pilot data in 2017 and 2018 of tertiary hospitals in Hubei province and related data from other reports were collected. Indicators including the actual number of beds, the number of employees, the actual total bed days occupied, and medical income were used as input indicators, and total admissions, number of discharges, weight of DRG and number of DRG groups were used as output indicators. 7 models were constructed using different indicator combinations. The efficiency of the hospital was calculated by the Bootstrap-DEA efficiency evaluation method. The relationship between hospital attributes and efficiency was analyzed by a generalized linear model.Results:There was an abnormal phenomenon that the higher the hospital level, the lower the efficiency in the efficiency value calculated by the traditional method. The efficiency values of county hospitals, city hospitals and provincial hospitals were 0.83, 0.74 and 0.71, respectively( P<0.01). DRG weight and group number were used as output for DEA analysis, and the efficiency values of county hospitals, city hospitals, and provincial hospitals were 0.95, 0.95 and 0.96( P=0.20)respectively. The DRG efficiency indications of county hospitals, city hospitals and provincial hospitals were 1.42, 1.11, 1.00 respectively( P<0.01). The higher the level, the lower the efficiency, while the efficiency values calculated by DEA were 0.84, 0.82, 0.86, respectively( P=0.58). Conclusions:The efficiency value calculated by the traditional method presents a systematic bias, which could be corrected effectively when DEA analysis using DRG weights is used as output indicator. The results developed new ideas of efficiency analysis for hospitals practicing DRG management.
