New blood safety regulations raise costs and pressure blood centers to improve their efficiency. Evaluation of platelet (PLT) production and discards between centers of different size and nationality may provide a basis for more efficient PLT inventory management.
Data were gathered retrospectively for 2000 to 2002 from 17 blood centers in 10 European countries. The descriptive analyses comprised evaluation of PLT production methods and volumes. Discard rates were surveyed also for 2003 to 2004. The number of cellular blood components produced per working hour was expressed as an arbitrary labor index.
Seven hospital blood banks and 10 centers with other administrative systems participated in the study. Buffy coat (BC) and apheresis PLTs were used by all centers except two preparing all PLTs by apheresis. In 2002, 73 percent of all PLTs were produced by the BC method, and PLTs were utilized from 41 percent of whole-blood donations. One center also produced PLTs by the PLT-rich plasma method. Mean annual production volume of PLTs varied greatly, from 3,345 to 103,643 units, with an increase of 5.6 percent from 2000 to 2002. Three-year mean discard rates varied between 6.7 and 25 percent, and yearly mean discard rates remained at 13 percent in 2000 to 2002 and also in 2003 to 2004. Arbitrary labor index varied from 2.4 to 7.3 between centers.
PLT discard rates were relatively high in the European blood centers. Detailed information on specific causes for high discard rates would help improve the efficiency of PLT management, because blood centers cannot regulate demand. Use of labor resources in component preparation also remains an important target for further research.
新的血液安全法规增加了成本,并给血站提高效率带来压力。评估不同规模和国籍的血站之间的血小板(PLT)产量和废弃量,可为更有效的PLT库存管理提供依据。
回顾性收集了2000年至2002年来自10个欧洲国家17个血站的数据。描述性分析包括对PLT生产方法和产量的评估。还调查了2003年至2004年的废弃率。将每工作小时生产的细胞血液成分数量表示为任意劳动指数。
7家医院血库和10家具有其他管理系统的血站参与了研究。除了两家通过单采制备所有PLT的中心外,所有中心都使用了 Buffy 层(BC)和单采PLT。2002年,所有PLT的73%通过BC法生产,41%的全血捐献的PLT被使用。一个中心也通过富含血小板血浆法生产PLT。PLT的年平均产量差异很大,从3345单位到103643单位不等,2000年至2002年增长了5.6%。三年平均废弃率在6.7%至25%之间,2000年至2002年以及2003年至2004年的年平均废弃率均保持在13%。各中心之间的任意劳动指数从2.4到7.3不等。
欧洲血站的PLT废弃率相对较高。关于高废弃率具体原因的详细信息将有助于提高PLT管理效率,因为血站无法调节需求。成分制备中劳动力资源的利用也是进一步研究的重要目标。
