Abstract:
OBJECTIVE To explore the grouping efficacy of diagnosis related group （DRG） and the influential factors of hospitalization cost in diabetes cases， and to provide theoretical support for improving DRG payment system， reducing medical cost and enhancing the efficiency of medical insurance funds. METHODS The information of 4 368 diabetic patients who were hospitalized in a 3A hospital in Xi’an from January 1， 2021 to June 30， 2023 was retrospectively analyzed， and DRG grouping of them was summarized； the hospitalization costs of patients in different DRG groups were analyzed by using one way ANOVA and Bonferroni multiple comparison. Coefficient of variation （CV） was used for evaluation within the group， and the influential factors of hospitalization costs were analyzed by one-way linear regression analysis and multi-factor linear regression analysis. RESULTS & CONCLUSIONS The CV values of the four DRG groups were all lower than 0.8， indicating good grouping results and good consistency within the group； the difference of hospitalization cost among the four groups was statistically significant （P＜0.05）， and the hospitalization cost of China Healthcare Security-DRG version 1.1 FW11 group was significantly higher than those of other three groups （P＜0.05）. Length of stay， drug cost， the number of other diagnoses， test cost and payment method have significant positive effects on the hospitalization cost of diabetic patients. Whether there is pharmacist intervention has a significant negative influence on the hospitalization cost of patients. Under the DRG payment method， medical institutions can consider multidisciplinary linkage and incorporate a variety of management and service tools， including pharmacist’s intervention， to develop refined management measures， to reduce the economic burden of patients’ families and society.
