Abstract:
Objective To analyze the effects of national centralized volume-based procurement(CVBP)on hospitaliza-tion expenses of patients undergoing artificial joint replacement under the Diagnosis-Related Group(DRG)payment model in a public hospital,and to provide evidence for advancing reforms in high-value medical consumables and healthcare payment sys-tems.Methods Data from patients undergoing artificial joint replacement in a tertiary public hospital in 2022 were collected.Statistical analysis was used to assess the surplus and deficit of DRG year-end settlements for these cases.By comparing cost com-positions across different medical insurance types,differences in total inpatient medical expenses,out-of-pocket payments,per-sonal medical insurance account expenditures,and pooled fund reimbursements were evaluated before and after CVBP implemen-tation.Results Following CVBP implementation,the sample hospital demonstrated significant improvements in reducing medical costs,alleviating patient financial burdens,and optimizing medical insurance fund utilization.Under the DRG payment model,operational performance remained stable.Post-CVBP,total hospitalization expenses,patient out-of-pocket payments,and pooled fund reimbursements all decreased significantly(P＜0.001).Conclusion The practice of centralized procurement of artificial joints can be extended to other high-value medical consumables,continuously promoting the reform of the medical and health sys-tem,and ultimately achieving mutually beneficial and sustainable development among healthcare providers,insurers,and patients.
