There is limited data on the cost-effectiveness of continuous-flow left ventricular assist devices (LVAD) in the United States particularly for the bridge-to-transplant indication. Our objective is to study the cost-effectiveness of a small intrapericardial centrifugal LVAD compared with medical management (MM) and subsequent heart transplantation using the respective clinical trial data. We developed a Markov economic framework. Clinical inputs for the LVAD arm were based on prospective trials employing the HeartWare centrifugal-flow ventricular assist device system. To better assess survival in the MM arm, and in the absence of contemporary trials randomizing patients to LVAD and MM, estimates from the Seattle Heart Failure Model were used. Costs inputs were calculated based on Medicare claim analyses and when appropriate prior published literature. Time horizon was lifetime. Costs and benefits were appropriately discounted at 3% per year. The deterministic cost-effectiveness analyses resulted in $69,768 per Quality Adjusted Life Year and $56,538 per Life Year for the bridge-to-transplant indication and $102,587 per Quality Adjusted Life Year and $87,327 per Life Year for destination therapy. These outcomes signify a substantial improvement compared with prior studies and re-open the discussion around the cost-effectiveness of LVADs.
关于美国持续性左心室辅助装置(LVAD)的成本效益数据有限,特别是在桥接移植适应证方面。我们的目的是使用各自的临床试验数据,研究一种小型心包内离心式 LVAD 与药物治疗(MM)和随后的心脏移植相比的成本效益。我们开发了一个马尔可夫经济框架。LVAD 臂的临床输入基于采用 HeartWare 离心流心室辅助装置系统的前瞻性试验。为了更好地评估 MM 臂的存活率,并且在没有将患者随机分配到 LVAD 和 MM 的当代试验的情况下,使用了西雅图心力衰竭模型的估计值。成本输入是根据医疗保险索赔分析和适当的先前发表的文献计算的。时间范围是终身。成本和效益按每年 3%进行适当贴现。确定性成本效益分析结果表明,桥接移植适应证的每质量调整生命年成本效益为 69768 美元,每生命年成本效益为 56538 美元,而对于终末期治疗的每质量调整生命年成本效益为 102587 美元,每生命年成本效益为 87327 美元。这些结果与先前的研究相比有了显著改善,重新开启了关于 LVAD 成本效益的讨论。
