In the EMPEROR-Reduced trial (Empagliflozin Outcome Trial in Patients with Chronic Heart Failure and a Reduced Ejection Fraction), empagliflozin plus standard of care reduced the composite of cardiovascular death or hospitalization for heart failure versus standard of care in adults with heart failure with reduced ejection fraction. This analysis investigated the cost-effectiveness of the 2 regimens from the perspective of US payors.
A Markov cohort model was developed based on Kansas City Cardiomyopathy Questionnaire Clinical Summary Score quartiles and death. Transition probabilities between health states, risk of cardiovascular/all-cause death, hospitalization for heart failure and adverse events, treatment discontinuation, and health utilities were estimated from trial data. Medicare and commercial payment rates were combined for treatment acquisition, acute event management, and disease management. An annual discount rate of 3% was used. Empagliflozin plus standard of care yielded 18% fewer hospitalizations for heart failure and 6% fewer deaths versus standard of care over a lifetime, providing cost-offsets while adding 0.19 life years and 0.19 quality-adjusted life years at an incremental cost of $16 815/patient. The incremental cost-effectiveness ratio was $87 725/quality-adjusted life years gained. Results were consistent across payors, subpopulations, and in deterministic sensitivity analyses. In probabilistic sensitivity analyses, empagliflozin plus standard of care was cost-effective in 3%, 62%, and 80% of iterations at thresholds of $50 000, $100 000, and $150 000/quality-adjusted life years.
Empagliflozin plus standard of care may prevent hospitalizations for heart failure, extend life, and increase quality-adjusted life years for patients with heart failure with reduced ejection fraction at an acceptable cost for US payors.
在EMPEROR-Reduced试验(恩格列净治疗射血分数降低的慢性心力衰竭患者的结局试验)中,与标准治疗相比,恩格列净联合标准治疗降低了射血分数降低的心力衰竭成人患者心血管死亡或因心力衰竭住院的复合终点事件。本分析从美国医保支付方的角度研究了这两种治疗方案的成本效益。
基于堪萨斯城心肌病问卷临床总结评分四分位数和死亡情况建立了马尔可夫队列模型。根据试验数据估算健康状态之间的转移概率、心血管/全因死亡风险、因心力衰竭住院和不良事件、治疗中断情况以及健康效用值。将医疗保险和商业支付费率合并用于计算治疗费用、急性事件管理费用和疾病管理费用。采用3%的年贴现率。与标准治疗相比,恩格列净联合标准治疗在患者一生中因心力衰竭住院的次数减少了18%,死亡人数减少了6%,在增加0.19个生命年和0.19个质量调整生命年的同时实现了成本抵消,增量成本为每位患者16,815美元。增量成本效益比为每获得一个质量调整生命年87,725美元。不同医保支付方、亚组人群以及确定性敏感性分析的结果均一致。在概率敏感性分析中,在每质量调整生命年50,000美元、100,000美元和150,000美元的阈值下,恩格列净联合标准治疗在3%、62%和80%的迭代中具有成本效益。
对于射血分数降低的心力衰竭患者,恩格列净联合标准治疗可能以美国医保支付方可接受的成本预防心力衰竭住院、延长生命并增加质量调整生命年。
