          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
          发概率等为模型敏感因素;概率敏感性分析结果显示,当WTP为1倍2021年我国人均GDP时,氯吡格雷方案具有经济性的概率约
          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
