摘 要 目的 从我国卫生体系角度出发,对达格列净与恩格列净治疗2型糖尿病肾病的经济性进行评价。方法 基于两项多中
心临床试验DECLARE-TIMI 58和EMPA-REG OUTCOME的研究数据,根据尿白蛋白与肌酐比值(UACR)划分2型糖尿病肾病患
者的疾病状态,构建Markov模型,设循环周期为1年,模拟至99%的患者死亡,模型产出为总成本与质量调整生命年(QALY)。通
过比较两种方案的增量成本-效果比(ICER)与意愿支付阈值(WTP,3倍我国2023年人均国内生产总值,即268 074元/QALY)判断
方案经济性,并采用单因素敏感性分析和概率敏感性分析检验结果的稳健性。结果 与达格列净相比,恩格列净方案的ICER为
44 334.82元/QALY,小于WTP,表明恩格列净方案具有经济性。单因素敏感性分析结果显示,两组非致命性心肌梗死发生率和微
量白蛋白尿状态的效用值对结果影响最大,但不会使基础分析结果发生颠覆性变化。概率敏感性分析显示基础分析结果具有稳
健性。结论 在以3倍我国2023年人均国内生产总值作为WTP时,与达格列净相比,恩格列净治疗2型糖尿病肾病更具有经济性。

ABSTRACT OBJECTIVE To evaluate the cost-effectiveness of dapagliflozin and empagliflozin in the treatment of type 2
diabetic kidney disease from the perspective of healthcare system in China. METHODS Based on the data from the two multicenter
clinical trials, DECLARE-TIMI 58 and EMPA-REG OUTCOME, a Markov model was constructed according to the urinary
albumin-to-creatinine ratio (UACR) of the patients with type 2 diabetic kidney disease with a cycle of 1 year, simulating until 99%
of patients died. The model outputs were total costs and quality-adjusted life year (QALY). The cost-effectiveness of the two
treatment regimens was assessed by comparing their incremental cost-effectiveness ratio (ICER) and the willingness-to-pay
threshold (WTP,set at three times China’s 2023 per capita gross domestic product, i. e., 268 074 yuan/QALY). Additionally,
oneway sensitivity analysis and probabilistic sensitivity analysis were performed to test the robustness of the base analysis results.
RESULTS Compared with dapagliflozin, the ICER for empagliflozin regimen was 44 334.82 yuan/QALY, which was below the
WTP , indicating its cost-effectiveness. The results of the oneway sensitivity analysis indicated that the incidence of non-fatal
myocardial infarction in both groups and the utility values associated with the microalbuminuria state had the most significant
impact on the outcomes, but did not change the base-case conclusion. The probabilistic sensitivity analysis indicated that the results
of the base-case analysis were robust. CONCLUSIONS With a WTP of three times China’s per capita gross domestic product in
2023, empagliflozin is more cost-effective than dapagliflozin in treating type 2 diabetic kidney disease.
