Iron deficiency is a common but treatable comorbidity in chronic heart failure (CHF) that is associated with impaired health-related quality-of-life (HRQoL). This study evaluates the cost-effectiveness of the intravenous iron preparation ferric carboxymaltose (FCM) for the treatment of iron deficiency in CHF from a Swedish healthcare perspective.
A cost-effectiveness analysis with a time horizon of 24 weeks was performed to compare FCM treatment with placebo. Data on health outcomes and medical resource use were mainly taken from the FAIR-HF trial and combined with Swedish cost data. An incremental cost-effectiveness ratio (ICER) was calculated as well as the change in per-patient costs for primary care and hospital care.
In the FCM group compared with placebo, quality-adjusted life years (QALYs) are higher (difference = 0.037 QALYs), but so are per-patient costs [(difference = SEK 2789 (€303)]. Primary care and hospital care equally share the additional costs, but within hospitals there is a major shift of costs from inpatient care to outpatient care. The ICER is SEK 75,389 (€8194) per QALY. The robustness of the result is supported by sensitivity analyses.
Treatment of iron deficiency in CHF with FCM compared with placebo is estimated to be cost-effective. The ICER in the base case scenario is twice as high as previously thought, but noticeably below SEK 500,000 (€54,300) per QALY, an informal average reference value used by the Swedish Dental and Pharmaceutical Benefits Agency. Increased HRQoL and fewer hospitalizations are the key drivers of this result.
缺铁是慢性心力衰竭(CHF)中一种常见但可治疗的合并症,与健康相关生活质量(HRQoL)受损有关。本研究从瑞典医疗保健的角度评估静脉注射铁制剂羧基麦芽糖铁(FCM)治疗CHF中铁缺乏症的成本效益。
进行了一项为期24周的成本效益分析,以比较FCM治疗与安慰剂治疗。健康结局和医疗资源使用数据主要取自FAIR-HF试验,并与瑞典成本数据相结合。计算了增量成本效益比(ICER)以及初级保健和医院护理中每位患者成本的变化。
与安慰剂组相比,FCM组的质量调整生命年(QALY)更高(差异 = 0.037 QALY),但每位患者的成本也更高[(差异 = 2789瑞典克朗(303欧元)]。初级保健和医院护理平均分担额外成本,但在医院内部成本有从住院护理向门诊护理的重大转移。ICER为每QALY75,389瑞典克朗(8194欧元)。敏感性分析支持了结果的稳健性。
与安慰剂相比用FCM治疗CHF中的缺铁症估计具有成本效益。基础病例情景中的ICER比之前认为的高出两倍,但明显低于瑞典牙科和药品福利局使用的非正式平均参考值每QALY500,000瑞典克朗(54,300欧元)。HRQoL的提高和住院次数的减少是这一结果背后的关键驱动因素
