2017年8月,英国科学家在《J Thromb Haemost》发表了对于首次无明显诱因的静脉血栓栓塞事件(VTE)后,重新开始抗凝治疗策略的经济学评估。

背景:目前对于首次无明显诱因的VTE后,推荐抗凝治疗至少3个月,但之后的疗程未明确。进一步的抗凝治疗降低了潜在的致命性VTE复发的风险,但代价是较高的出血风险,也可能是致命的。

目的:进行经济学评价,旨在估算延长抗凝治疗时间与无延长相比,在基于远期无明显诱因VTE风险的患者中的长期成本效果。

方法:建立一个采用每月循环,终身时间范围,模拟患者水平的Markov模型,数据来自于英国国民健康服务(NHS)/个人化社会服务(PSS),采用医保支付视角。

结果:基于病例模型的结果显示,如果每生命治疗调整年(QALY)决策制定者意愿支付阈值为£20000,预计1年VTE风险为17.5%及以上的患者进行延长抗凝治疗可能具有成本效果。然而,概率敏感性分析显示,该模型对整体参数不确定性高度敏感,基于成本效果考虑选择最佳决策时应注意。单变量敏感性分析表明,抗凝治疗无效和死亡风险这样的变量在驱动模型结果方面很有影响力。

结论:本研究介绍了首个考虑无明显诱因的VTE患者延长抗凝治疗时的决策规则使用的经济模型。未来需要更好的数据来预测该部分患者在治疗期间的长期出血风险。
