Abstract:Objective：To explore the structure and influencing factors of DRG cost inheart failure cases. Methods：The DRG payment data of 564 cases with heart failure in the department of cardiology of a certain tertiarygrade A hospital in Kunming in 2020 were retrospectively selected to analyze the structure，influencing factors and correlation of hospitalization costs. Results：Most of the patients with heart failure were elderly men，and the average hospital stay was 11.47 days. Patients aged 45-60 years had the highest mean total hospitalization cost，average on ￥19，624.05 and median on ￥10，042.06.The related factors of higher hospitalization cost were length of stay and consumables cost，consumables cost accounts for a large proportion（38.84%）. 89.72% of the patients’ hospitalization expenses are less than ￥30，000. High value consumables were used in 42 cases which average on ￥99，108.46 and median on ￥123，292.00. Conclusion：Under the DRG payment method，the influencing factors of heart failure hospitalization cost include age，gender，length of stay，consumables cost and drug cost，and consumables account for a relatively high proportion of the treatment cost of this disease.
