          摘   要  目的  从我国卫生体系视角出发,评估头孢地尔对比最佳可用疗法(BAT)或标准疗法(SOC)治疗确诊或疑似耐碳青霉烯
          类革兰氏阴性菌严重感染的经济性,并探讨其合理定价。方法  基于两项Ⅲ期临床试验(CREDIBLE-CR与GAME CHANGER)数
          据构建决策树模型,模拟头孢地尔在确诊耐碳青霉烯类革兰氏阴性菌感染的救治场景(场景一)与疑似上述耐药菌感染的初始经
          验性治疗场景(场景二)下的成本-效果。主要结局指标为增量成本-效果比(ICER),意愿支付阈值设定为2024年我国人均国内生
          产总值(GDP)的1~3倍。采用单因素及概率敏感性分析检验结果的稳健性,并在此基础上探索头孢地尔在我国市场的合理定价
          区间。结果  场景一的结果表明,头孢地尔组的治愈率高于BAT组(47.50% vs. 34.21%),但其ICER为415 065.03元/例治愈,超出
          3倍我国人均GDP的阈值;而场景二揭示,头孢地尔相对于SOC的ICER高达1 362 446.16元/例治愈,远超意愿支付阈值。敏感性
          分析表明,头孢地尔的治疗时间与价格是影响方案经济性的关键因素。在上述 2 个场景中,头孢地尔单价需分别降至 683.47、
          242.00元/g以下方具经济性。结论  基于当前市场价格,头孢地尔治疗确诊或疑似耐碳青霉烯类革兰氏阴性菌严重感染在我国卫
          生体系中的经济性不足,需通过价格谈判或医保分层支付策略提高其可及性。

          ABSTRACT    OBJECTIVE  To  evaluate  the  cost-effectiveness  of  cefiderocol  versus  best  available  therapy (BAT)  or  standard-of-
          care (SOC) for the treatment of confirmed or suspected carbapenem-resistant Gram-negative bacterial (CRGNB) serious infections
          from  the  perspective  of  the  Chinese  healthcare  system,  and  to  explore  its  reasonable  pricing.  METHODS  A  decision  tree  model
          was  constructed  based  on  data  from  two  phase  Ⅲ  clinical  trials (CREDIBLE-CR  and  GAME  CHANGER)  to  simulate  the  cost-
          effectiveness  of  cefiderocol  in  two  scenarios:  salvage  therapy  for  confirmed  CRGNB  infection (scenario  1)  and  empirical  therapy
          for  suspected  CRGNB  infection (scenario  2).  The  primary  outcome  measure  was  the  incremental  cost-effectiveness  ratio (ICER).
          The willingness-to-pay (WTP) was set at 1 to 3 times China’s per capita GDP in 2024. To verify the robustness of the results, one-
          way  and  probabilistic  sensitivity  analyses  were  conducted,  and  based  on  these,  a  reasonable  price  range  for  cefiderocol  in  the
          Chinese market was explored. RESULTS The results for scenario 1 showed that the clinical cure rate in the cefiderocol group was
          higher than that in the BAT group (47.50% vs. 34.21%), but its ICER was 415 065.03 yuan per cured case, exceeding three times
          China’s  GDP  per  capita.  Scenario  2  revealed  that  the  ICER  for  cefiderocol  relative  to  SOC  was  as  high  as  1  362  446.16  yuan  per
          cured  case,  far  exceeding  the  WTP.  Sensitivity  analysis  indicated  that  the  treatment  duration  and  price  of  cefiderocol  were  key
          factors  affecting  its  cost-effectiveness.  In  the  two  scenarios  described  above,  the  unit  price  of  cefiderocol  must  fall  below  683.47
          and  242.00  yuan/g,  respectively,  to  be  considered  cost-effective.  CONCLUSIONS  Based  on  the  current  market  price,  cefiderocol
          lacks  sufficient  cost-effectiveness  for  treating  confirmed  or  suspected  CRGNB  serious  infections  within  China’s  healthcare  system.
