Cost-utility Analysis of 3 Antiemetic Regimens to Prevent Nausea and Vomiting Caused by Multi-day Cisplatin- containing Chemotherapy Based on the Real World / 中国药房

ABSTRACT

OBJECTIVE：To provide reference for clinical decision-making related to chemotherapy-induced nausea and vomiting（CINV）. METHODS ：The medical records of patients diagnosed as malignant tumor receiving multi-day cisplatin-containing chemotherapy in our hospital were collected by hospital information system from Jan.-Dec. 2012. The medical records were divided into tropisetron group ，ramosetron group and palonosetron group according to different schemes of 5-hydroxytryptamine-3 receptor antagonist. The covariates of 3 groups were balanced by propensity score matching method ；cost-utility analysis was conducted for the 3 matched antiemetic schemes ；one-way sensitivity analysis and sampling uncertainty analysis were also conducted. RESULTS ： The results of cost-utility analysis showed that treatment cost of one observation period of tropisetron group was 237.71 yuan and utility were 0.054 68 QALYs；that of ramosetron group was 242.37 yuan and utility were 0.055 26 QALYs，and that of palonosetron group was 319.24 yuan and utility were 0.055 76 QALYs. Compared with tropisetron group ，the ICER of palonosetron group was 75 155.69 yuan/QALY；Compared with ramosetron group ，the ICER of palonosetron group was 152 062.07 yuan/QALY. Both of them were lower than 3 times of China ’s 2020 per capita GDP （217 341 yuan/QALY）. The results of sensitivity analysis and sampling uncertainty analysis demonstrated that the results of basic analysis were robust. CONCLUSIONS ：Under the current drug price，the antiemetic regimen based on palonosetron is more economical for the prevention of CINV caused by multi-day chemotherapy containing cisplatin.
