        摘  要   目的:评价格卡瑞韦/哌仑他韦(G/P)对比艾尔巴韦/格拉瑞韦(EBR/GZR)治疗基因1b(GT1b)型无肝硬化慢性丙肝初治
        患者的经济性,为医药卫生决策提供证据支持。方法:在假设G/P和EBR/GZR两种药物治疗方案均采取医保谈判前的中标价格
       (情境1)和假设EBR/GZR价格下降85%、G/P价格下降80%(情境2)的两种价格情境下构建Markov模型,模拟10 000名GT1b型
        无肝硬化慢性丙肝初治患者队列在不同治疗方案下的终生累计成本和健康产出,计算增量成本-效果比(ICER)。使用单因素敏感
        性分析和概率敏感性分析对结果进行验证,并在保持情境2其他参数不变的情况下,分析G/P方案具有成本-效果优势的最高价格
       (降价比例)。结果:在设定的两种情境下,G/P方案相比于EBR/GZR方案成本更高(情境1:68 800元vs. 62 338元;情境2:13 760
        元vs. 11 490元),健康效用值更高(情境1:14.97 QALY vs. 14.90 QALY;情境2:14.97 QALY vs. 14.90 QALY),ICER值小于意愿支
        付阈值(情境1:92 314元/QALY;情境2:32 428元/QALY);单因素敏感性分析中大部分参数改变不影响基础分析结果,概率敏感
        性分析证实了基础分析的结果。G/P 方案价格至少降低62%才具有成本-效果优势。结论:在设定的价格情境下,G/P 方案治疗
        GT1b型无肝硬化慢性丙肝初治患者较EBR/GZR方案更具有成本-效果优势。

        ABSTRACT    OBJECTIVE:To evaluate the economics of glecaprevir/pibrentasvir(G/P)versus elbasvir/grazoprevir(EBR/GZR)
        in chronic hepatitis C genotype 1b(GT1b)treatment-naive patients without cirrhosis,and to provide evidence support for medical
        and health decision-making. METHODS:Under assuming the bid price of G/P and EBR/GZR therapy schemes before medical
        insurance negotiation was adopted(scenario 1)and assuming that the price of EBR/GZR was reduced by 85% and the price of G/P
        was reduced by 80%(scenario 2),Markov model was developed to simulate the lifetime cost and health outcomes progress of
        10 000 untreated chronic hepatitis C GT1b treatment-naive patients without cirrhosis and calculate incremental cost-effectiveness
        ratio(ICER). Single factor sensitivity analysis and probability sensitivity analysis were conducted to verify the results. The highest
        price (price reduction ratio) of G/P scheme was analyzed with cost-effectiveness advantage,when other parametes kept stable
        under scenario 2. RESULTS:Under 2 kinds of scenarios,compared with EBR/GZR scheme,G/P scheme had higher cost(scenario
        1:68 800 yuan vs. 62 338 yuan;scenario 2:13 760 yuan vs. 11 490 yuan)and healty utility(scenario 1:14.97 QALY vs. 14.90
        QALY;scenario 2:14.97 QALY vs. 14.90 QALY),and ICER value of G/P was lower than willingness-to-pay threshold(scenario
        1:92 314 yuan/QALY;scenario 2:32 428 yuan/QALY). The change of most parameters in single factor sensitivity analysis didn’t
        influence the results of base-case analysis,and the findings from the base-case analysis were confirmed by probability sensitivity
        analyses. The price of G/P scheme needed to be reduced by at least 62% to realize cost-effective advantage. CONCLUSIONS:
        Under the set price scenario,G/P scheme has cost-effectiveness advantages than EBR/GZR scheme in chronic hepatitis C GT1b
        treatment-naive patients without cirrhosis.
