          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。

          Pharmacoeconomic evaluation of dapagliflozin and empagliflozin in the treatment of type 2 diabetic kidney
          disease

          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.
