| Objective To analyze the effect of DRG on the inpatient cost control of patients with gallbladder stones combined with chronic cholecystitis surgery based on propensity matching. Methods Data on inpatient costs of 1,010 patients with gallbladder stones combined with chronic cholecystitis surgery in a tertiary general hospital in Anhui province from January 2021 to December 2022 were collected and divided into DRG group(n=570) and non-DRG group(n=440) according to different payment methods. Descriptive statistical analysis, propensity score method, and rank sum test were used to test the hospitalization cost of DRG and non-DRG groups after balancing the confounding factors between cases. Results A total of 1,010 cases were included,and 852 cases were successfully matched by propensity score matching.Among them,there were statistically significant differences in age and hospitalization days between the DRG and non-DRG groups of patients with gallbladder stones combined with chronic cholecystitis before matching(P<0.05).Patients', hospitalization costs accounted for a higher proportion of consumables and medication costs. Statistical tests after propensity matching showed that total hospitalization costs(Z=7.519,P<0.001),out-of-pocket amounts(Z=13.903,P<0.001),health insurance reimbursement(Z=11.561,P<0.001),comprehensive medical services(Z=2.188,P=0.029),surgical costs(Z=2.256,P=0.024),medication(Z=3.202,P=0.001),consumables(Z=2.229,P=0.026),and diagnostics(Z=8.263,P<0.001) all had statistically significant differences. Conclusions DRG has a cost-control effect on out-of-pocket expenses,comprehensive medical service fees, surgical fees,drug fees,consumable fees and diagnostic fees for patients with gallbladder stones combined with chronic cholecystitis,and the overall cost-controlling effect of hospitalization is better, but there is still room for optimization in terms of cost structure. |
