        摘   要   目的 对恩格列净治疗射血分数降低的心力衰竭(HFrEF)进行药物经济学评价,为临床合理用药和医疗卫生决策提供循
        证依据。方法 运用马尔可夫模型对恩格列净治疗HFrEF的方案进行成本-效果分析,评价标准治疗方案联合恩格列净(恩格列净
        组)与单用标准治疗方案(标准治疗组)的成本和效果。临床参数来自EMPEROR-Reduced研究,成本和健康效用值数据来自已发
        表的文献。模型的循环周期为1个月,模拟时间为20年。采用单因素敏感性分析和概率敏感性分析对成本-效果分析的结果进行
        验证。结果 恩格列净组较标准治疗组每增加1个质量调整生命年要多花费37 995.94元,低于1倍2020年中国人均国内生产总值
        (GDP),即72 447元。单因素敏感性分析结果显示,两组患者的稳定状态住院率是对增量成本-效果比影响最大的因素。概率敏
        感性分析结果显示,当支付意愿阈值(WTP)取1倍2020年中国人均GDP(72 447元)时,恩格列净组有58.8%的概率具有成本-效
        果优势;当WTP取3倍2020年中国人均GDP(217 341元)时,恩格列净组有63.8%的概率具有成本-效果优势。结论 采用标准治
        疗方案联合恩格列净治疗HFrEF较单纯采用标准治疗方案更具有成本-效果优势,但经济性概率不高。

        ABSTRACT    OBJECTIVE To conduct the pharmacoeconomic evaluation of empagliflozin in the treatment of heart failure with
        reduced ejection fraction (HFrEF),and to provide evidence-based reference for rational drug use and medical and healthy
        decision-making. METHODS A Markov model was used to perform a cost-effectiveness analysis of the regimen of empagliflozin in
        the treatment of HFrEF,and to evaluate the cost and effectiveness of standard treatment plan plus empagliflozin(empagliflozin
        group)vs. standard treatment plan(standard treatment group). Clinical parameters were obtained from the EMPEROR-Reduced
        study;cost and utility data came from the published literatures. The cycle of the model was 1 month and the simulation time was
        20 years. Single-factor sensitivity analysis and probability sensitivity analysis were performed to validate the results of
        cost-effectiveness analysis. RESULTS Compared with the standard treatment group,each additional quality-adjusted life year in the
        empagliflozin group cost 37 995.94 yuan more,which was less than China’s 1 time GDP per capita in 2020(72 447 yuan). The
        results of single factor sensitivity analysis showed that steady-state hospitalization rate of 2 groups was the most important factor
        affecting the incremental cost-effectiveness ratio. The results of probability sensitivity analysis showed that when the
        willingness-to-pay threshold(WTP)was 1 time GDP per capita in 2020(72 447 yuan),the probability of empagliflozin group
        with cost-effectiveness advantage was 58.8%;when the WTP was 3 times GDP per capita in 2020(217 341 yuan),the probability
        of empagliflozin group with cost-effectiveness advantage was 63.8% . CONCLUSIONS Compared with standard treatment plan
        alone,standard treatment plan plus empagliflozin is more cost-effective in the treatment of HFrEF. However,the economic
        probability is not high.
