摘 要 目的 评价抗血小板药物氯吡格雷、阿司匹林单药方案用于缺血性脑卒中二级预防的经济性,为临床用药和相关决策提
供经济学证据和参考。方法 基于CAPRIE试验构建Markov模型,通过查阅相关文献确定风险事件发生概率、健康效用值以及风
险事件管理成本等。模型循环周期为6个月,模拟时限为10年,年贴现率为5%。以总成本、质量调整生命年(QALY)和增量-成本
效果比(ICER)作为主要计算结果,应用TreeAge Pro软件对上述2种方案进行成本-效用分析,并采用单因素敏感性分析、概率敏
感性分析和情境分析来验证基础分析结果的稳健性。结果 氯吡格雷方案与CAPRIE试验中325 mg/d剂量阿司匹林方案相比用
于脑卒中二级预防在模拟10、20、30年时的ICER值分别为4 284.06、4 201.20、3 986.78元/QALY,均小于以1倍2021年我国人均国
内生产总值(GDP)作为的意愿支付(WTP)阈值。而氯吡格雷方案与我国临床常用剂量(100 mg/d)的阿司匹林方案相比用于脑卒
中二级预防在模拟 10、20、30 年时的 ICER 值分别为 58 238.27、42 164.72、36 164.77 元/QALY,也均小于 WTP 阈值。当对比 325
mg/d剂量的阿司匹林方案时,单因素敏感性分析结果显示,氯吡格雷周期成本、阿司匹林周期成本、2组治疗方案的脑卒中首次复

为66.5%。情境分析结果显示,无论是10、20、30年3种模拟时限,还是选用不同剂量(50、100、150、200、250 mg/d)阿司匹林方案,
均不会使基础分析结果翻转。结论 相较于阿司匹林单药方案,氯吡格雷单药方案用于缺血性脑卒中二级预防更具有经济性。

ABSTRACT OBJECTIVE To evaluate the cost-effectiveness of clopidogrel versus aspirin monotherapy regimens for secondary
prevention of ischemic stroke and to provide economic evidence and reference for clinical medication and decision-making.
METHODS Based on the CAPRIE trial, a Markov model was constructed; the probabilities of risk events, health utility values,
and costs of risk event management were obtained from relevant literature. The cycle length was 6 months, and the time horizon
was 10 years. A discount rate of 5% per year was applied. The primary outcomes were total costs, quality-adjusted life-years
(QALYs), and incremental cost-effectiveness ratio (ICER). Cost-utility analysis was performed for above 2 regimens by using
TreeAge Pro software. The one-way sensitivity analysis, probabilistic sensitivity analysis and scenario analysis were conducted to
validate the robustness of the analyses. RESULTS Compared
