This study aimed to estimate the cost of platelet transfusion in patients with chronic liver disease (CLD)-associated thrombocytopenia undergoing an elective procedure in the United States.
The study was conducted in two parts: development of a conceptual framework identifying direct, indirect and intangible costs of platelet transfusion, followed by the estimation of the total cost of platelet transfusion in patients with CLD-associated thrombocytopenia before an elective procedure in the United States using the conceptual framework and cost data obtained from a literature search. The cost of the entire care required to raise a patient's platelet count before the procedure was considered.
The final conceptual framework included the costs of generating the supply of platelets, the platelet transfusion itself, adverse events associated with platelet transfusion and refractoriness to platelet transfusion. When costs were accounted for in all the framework cost categories, the total direct cost of a platelet transfusion in a patient with CLD and associated thrombocytopenia was estimated to be in the range of $5258 to $13,117 (2017 US dollars) in the United States. The largest portion of costs was incurred by the transfusion event itself ($3723 to $4436) and the cost of refractoriness ($874 to $7578), which included the opportunity cost of a delayed procedure and subsequent platelet transfusions with human leukocyte antigen-matched platelets.
Although we were unable to include all cost components identified in the conceptual framework in our total cost estimate, thus likely underestimating the true total cost, and despite the data gaps and challenges limiting our estimate of the full cost of a platelet transfusion in patients with CLD-associated thrombocytopenia undergoing an elective procedure in the United States, this study outlines a comprehensive conceptual framework for estimating the cost elements of a platelet transfusion in these patients.
本研究旨在估算美国慢性肝病(CLD)相关血小板减少症患者接受择期手术时血小板输注的成本。
本研究分两部分进行:首先构建一个概念框架,确定血小板输注的直接、间接和无形成本;然后使用该概念框架以及从文献检索中获得的成本数据,估算美国CLD相关血小板减少症患者在择期手术前血小板输注的总成本。研究考虑了在手术前提高患者血小板计数所需的全部护理成本。
最终的概念框架包括血小板供应产生的成本、血小板输注本身的成本、与血小板输注相关的不良事件以及对血小板输注的难治性成本。当对所有框架成本类别进行成本核算时,美国CLD及相关血小板减少症患者血小板输注的总直接成本估计在5258美元至13117美元(2017年美元)之间。成本的最大部分由输注事件本身(3723美元至4436美元)和难治性成本(874美元至7578美元)产生,其中难治性成本包括手术延迟的机会成本以及随后使用人类白细胞抗原匹配血小板进行的血小板输注成本。
尽管我们无法在总成本估算中纳入概念框架中确定的所有成本组成部分,因此可能低估了真实的总成本,并且尽管存在数据缺口和挑战限制了我们对美国CLD相关血小板减少症患者接受择期手术时血小板输注全部成本的估算,但本研究概述了一个用于估算这些患者血小板输注成本要素的综合概念框架。
