Abstract：Objective To analyze the grouping effect of DRG, the hospitalization costs composition and structural changes in patients with ischemic stroke, so as to provide basis for the implementation of DRG payment reform and precise fee control.Methods The intra-group variation of DRG was evaluated by coefficient of variation (CV）, and the inter-group comparison was evaluated by rank sum test; the structural change of hospitalization expenses between DRG groups was analyzed by the structural change degree.Results The CV of each DRG group was less than 1; the difference of hospitalization expenses among the three groups was statistically significant (P<0.001), while the difference of hospitalization days among the three groups was not statistically significant (P=0.857); the proportion of drug costs in each group was the highest, reaching over 40%, followed by the diagnostic fee, which reached over 30%. The structure of BR21 compared with BR25 had the largest variation (10.86%), the treatment cost structure of BR21 compared with other groups had the largest contribution rate, and the drug cost structure of BR25 compared with other groups had the largest contribution rate.Conclusion The grouping effect of ischemic stroke is reasonable, but the cost structure still needs to be optimized. We should raise the charging standard for medical service projects, standardize the clinical pathway, and establish a performance evaluation scheme and a reasonable and effective cost control mechanism that are compatible with DRG payment.
