Research on Hospitalization Costs of Patients Undergoing Coronary Stent Implantation Based on Structural Variation Degree and Grey Relational Analysis
Objective To investigate the composition of hospitalization costs for patients undergoing coronary stent implantation surgery and the influencing factors,providing a reference for controlling medical expenses,reforming payment and strengthening the management of medical consumables.Methods The data on hospitalization costs for 16810 patients undergoing coronary stent implantation surgery from 2019 to the first half of 2023 in W hospital was selected.Structural variation degree analysis and grey relational analysis methods were used to analyze the proportion changes of various expenses for patients and their correlation with hospitalization costs.Statistical methods were also used to analyze the changes in the consumption of major consumables before and after centralized procurement.Results From 2019 to the first half of 2023,the structural variation contribution rate of consumables expenses to the hospitalization costs of patients undergoing coronary stent implantation surgery was the highest,which was 49.20%.Consumables expenses had the highest correlation with hospitalization costs for patients,at 0.922.In the first half of 2023 compared to 2019,examination fees increased by 81.99%.After centralized procurement,the per capita use of coronary stent increased to 2.13.The monthly average number of patients undergoing coronary stent implantation surgery increased by 66.53%.Conclusion The hospitalization cost of patients undergoing coronary stent implantation surgery decreased significantly after the cancellation of consumables addition and the implementation of centralized procurement policy.Centralized procurement is the internal driving force behind the surge in medical visits.It is suggested that hospitals further control the hospitalization cost of patients by optimizing the prices of medical services,strengthening the management of medical consumables,establishing standardized clinical pathways,and promoting centralized quantity-based procurement policie.
