          及转归,研究时限为1年。计算两种治疗方案的总成本和质量调整生命年(QALYs),并计算增量成本-效果比;对治疗8周之后到
          研究时限1年之间的疗效参数进行不同假设,基于中国卫生体系和全社会视角进行情境分析,并进行敏感性分析。结果  基础分
          析结果显示,与蔗糖铁相比,羧基麦芽糖铁方案的增量效果为0.007 QALYs,费用可节省1 038元,健康产出更高而总成本更低,属
          于绝对优势方案;情境分析和单因素敏感性分析结果与基础分析一致。概率敏感性分析结果显示,分别以1、2、3倍2022年中国人

          ABSTRACT    OBJECTIVE  To  evaluate  the  cost-effectiveness  of  Ferric  carboxymaltose  injection  in  the  treatment  of  iron
          deficiency  anemia  in  adult  Chinese  patients.  METHODS  From  the  perspective  of  China’s  health  system,  the  partitioned  survival
          model  was  constructed  to  simulate  the  treatment  process  and  outcome  of  patients  with  iron  deficiency  anemia  using  ferric
          carboxymaltose  and  iron  sucrose  based  on  the  ferric  carboxymaltose  phase  Ⅲ  clinical  trial  in  China (NCT03591406).  The  study
          period  was  1  year.  Total  costs  and  quality-adjusted  life  years (QALYs)  were  calculated  for  both  treatment  regimens,  and
          incremental  cost-effectiveness  ratios  were  calculated.  Scenario  analysis  was  performed  with  different  assumptions  for  efficacy
          parameters between 9th week and the end of 1 year, and from the perspective of China’s health system and the entire society. The
          sensitivity analysis was also performed. RESULTS In the basic analysis, compared with iron sucrose, incremental effectiveness of
          ferric  carboxymaltose  therapy  was  0.007  QALYs,  with  an  additional  savings  of  1  038  yuan  per  patient.  Ferric  carboxymaltose
          therapy was  more effective and less  costly,  presenting an absolute advantage. The results of  the scenario analysis and single-factor
          sensitivity  analysis  were  consistent  with  the  basic  analysis.  Probability  sensitivity  analysis  showed  that  when  the  willingness-to-pay
          threshold  was  1,  2,  3  times  gross  domestic  product  per  capita  in  2022,  the  probability  of  ferric  carboxymaltose  with  a  cost-
          effectiveness  advantage  was  88.2%,94.5%  and  97.6%,respectively.  CONCLUSIONS  For  Chinese  adults  with  iron  deficiency
          anemia, ferric carboxymaltose is a cost-effective treatment for iron deficiency anemia, compared with iron sucrose.
