Study on the Influencing Factors of Patient Hospitalization Costs Under DRG Reform——Taking EB19 Lung Major Surgery as an Example
Objective:The paper explores the changes in the cost structure and influencing factors of inpatients in the EB19 lung major surgery group after the reform of DRG payment methods,to provide a reference for the reasonable management of diagnostic and treatment costs.Methods:Retrospective analysis was used to analyze the medical record information of EB19 patients in the thoracic surgery department of a large tertiary hospital.Descriptive statistics,univariate analysis,and multiple linear regression models were used to analyze the influencing factors of patient hospitalization costs.Results:A total of 3734 patients were included in this study.The results of univariate analysis showed that gender,insurance type,age,length of stay,number of other diagnoses,number of other surgeries/procedures,and the use of robot-assisted operations all had an impact on hospitalization costs,with statistical differences among different groups(P＜0.001).Spearman correlation analysis showed that the top three factors affecting hospitalization costs were consumables,surgery,and medication costs,with consumables having the most significant impact on hospitalization costs(P＜0.001).Conclusion:In order to avoid the abuse of high-value consumables,it is necessary to continuously strengthen fund supervision,refine disease management,and achieve high-quality and sustainable development of departments and hospitals guided by valued diagnosis and treatment.
