Hospitalization expenses and influencing factors for medical insurance patients undergoing knee replacement in a grade-A tertiary hospital in Shandong Province
Objective To explore factors influencing the hospitalization expenses of medical insurance patients undergo-ing knee replacement and to analyze the changes in hospitalization expenses before and after centralized volume-based procurement of artificial joints,so as to provide reference for relevant research and healthcare decision-making.Methods A generalized linear model was constructed to analyze the factors influencing hospitalization expenses of 3,631 patients undergoing knee replacement in the First Affiliated Hospital of Shandong First Medical University during Jan.2021 and Oct.2022.Balanced data set obtained by propensity score matching were used to analyze the changes in cost structure before and after centralized procurement.Results The types of medical insurances,surgical sites,surgical types,types of diseases,centralized procurement,length of hospitalization and patients'ages were factors influencing hospitalization expenses.After centralized procurement,the average hospitalization expenses decreased from 48,928.24 CNY to 26,365.42 CNY,the average material costs decreased from 33,762.06 CNY to 10,939.82 CNY,and the pro-portion of material costs decreased from 69.00%to 41.49%.Conclusion The material costs account for the largest pro-portion in the hospitalization expenses of knee replacement,and centralized procurement is the most influential factor af-fecting hospitalization expenses.The material costs and hospitalization expenses are significantly reduced by centralized volume-based procurement of artificial joints,which reduces the economic burden of patients.
