Large volume delayed sampling (LVDS) and pathogen reduction technology (PRT) are strategies for platelet processing to minimize transfusion of contaminated platelet components (PCs). This study holistically compares the economic and clinical impact of LVDS and PRT in the United States.
A decision model was constructed to simulate collection, processing, and use of PCs and to compare processing strategies: PRT with 5-day shelf life, LVDS with 7-day shelf life (LVDS7), and LVDS with 5-day shelf life extended to 7 days with secondary testing (LVDS5/2). Target population was adults requiring two or more transfusions. Collection, processing, storage, and distribution data were obtained from the National Blood Collection and Utilization Survey and published literature. Patient outcomes associated with transfusions were obtained from AABB guidelines, meta-analyses, and other published clinical studies. Costs were obtained from reimbursement schedules and other published sources.
Given 10,000 donated units, 9512, 9511, and 9651 units of PRT, LVDS5/2, and LVDS7 PCs were available for transfusion, respectively. With these units, 1502, 2172, and 2329 transfusions can be performed with similar levels of adverse events. Assuming 30 transfusions a day, a hospital would require 69,325, 47,940, and 45,383 units of PRT, LVDS5/2, and LVDS7 platelets to perform these transfusions. The mean costs to perform transfusions were significantly higher with PRT units.
Compared with PRT, LVDS strategies were associated with lower costs and higher PC availability while patients experienced similar levels of adverse events. Increased utilization of LVDS has the potential to improve efficiency, expand patient access to platelets, and reduce health care costs.
大容量延迟采样(LVDS)和病原体减少技术(PRT)是血小板处理的策略,旨在最大程度地减少污染血小板成分(PCs)的输血。本研究综合比较了美国 LVDS 和 PRT 的经济和临床影响。
构建了一个决策模型来模拟 PC 的采集、处理和使用,并比较了处理策略:PRT 具有 5 天的货架寿命,LVDS 具有 7 天的货架寿命(LVDS7),以及 LVDS 具有 5 天的货架寿命,通过二次检测延长至 7 天(LVDS5/2)。目标人群为需要两次或两次以上输血的成年人。采集、处理、储存和分配数据来自国家血液采集和利用调查以及已发表的文献。输血相关的患者结局数据来自 AABB 指南、荟萃分析和其他已发表的临床研究。成本来自报销计划和其他已发表的来源。
假设 10000 个单位的捐献,PRT、LVDS5/2 和 LVDS7 的 PC 分别有 9512、9511 和 9651 个单位可供输血。使用这些单位,可以进行 1502、2172 和 2329 次输血,且不良事件水平相似。假设每天进行 30 次输血,医院需要 69325、47940 和 45383 个单位的 PRT、LVDS5/2 和 LVDS7 血小板来进行这些输血。进行输血的平均成本与 PRT 单位显著更高。
与 PRT 相比,LVDS 策略与较低的成本和更高的 PC 可用性相关,而患者经历相似水平的不良事件。增加 LVDS 的利用率有可能提高效率、扩大患者对血小板的获取,并降低医疗保健成本。
