基于决策树模型的一次性胃肠镜的经济学评价OA

Objective To systemically evaluate the economics of using EndoFresh disposable gastrointestinal endoscope compared to conventional gastrointestinal endoscopes for diagnosis and treatment of gastrointestinal diseases,and provide evidence-based recommendations to government and clinical decision-making.Methods A decision tree model was established for cost-effectiveness analysis between the EndoFresh disposable gastrointestinal endoscope and conventional reusable endoscope,with effectiveness parameters and cost parameters sourced from literature and expert consultation.The uncertainty of model parameters was analyzed by single-factor sensitivity analysis,and the simulated time span was 30 days.Results The incremental cost-effectiveness ratio(ICER)for EndoFresh single-use gastrointestinal endoscopy treatment compared to conventional reusable endoscopy treatment in the general patient population was 304255.8.The risk of secondary infection in patients undergoing conventional endoscopy had the greatest impact on the robustness of the results.In susceptible patients,the ICER for EndoFresh single-use gastrointestinal endoscopy treatment compared to conventional reusable endoscopy treatment was 216613.7,with the risk of secondary infection in patients undergoing conventional endoscopy having the greatest impact on the robustness of the results.Conclusion Taking 3 times China's GDP per capita in 2021 as the threshold,EndoFresh one-time gastroenteroscopy is more cost-effective than conventional gastroenteroscopy in susceptible patient groups.
