A sufficient supply of safe, high-quality blood components for transfusion is essential to the healthcare system in Germany. The requirements for the current reporting system are laid down in the German Transfusion Act. The present work elaborates on the advantages and limitations of the current reporting system and investigates the feasibility of a pilot project that collects specific data on blood supply based on weekly reports.
Selected data on blood collection and supply from 2009 to 2021 derived from the §21 German Transfusion Act database were examined. In addition, a pilot study over a period of 12 months was conducted on a voluntary basis. The number of red blood cell (RBC) concentrates was documented and stock availability was calculated weekly.
From 2009 to 2021, the annual number of RBC concentrates decreased from 4.68 to 3.43 million, the per capita distribution decreased from 58 to 41 RBC concentrates per 1,000 inhabitants. These figures did not change significantly during the COVID-19 pandemic. The data of the 1-year pilot project represented 77% of the released RBC concentrates in Germany. Percentage share of O RhD positive RBC concentrates fluctuated between 35% and 22% and for O RhD negative concentrates between 17% and 5%. The availability of O RhD positive RBC concentrate stocks varied between 2.1 and 7.6 days.
The data presented shows a decrease in annual RBC concentrate sales over an 11-year period and no further change over the past 2 years. A weekly monitoring of blood components detects acute problems in RBC provision and supply. Close monitoring seems helpful but should be combined with a nationwide supply strategy.
为输血提供充足的安全、高质量血液成分对德国医疗系统至关重要。德国输血法案规定了当前报告系统的要求。本研究阐述了当前报告系统的优点和局限性,并调查了一个基于周报收集血液供应特定数据的试点项目的可行性。
检查了2009年至2021年源自德国输血法案第21条数据库的采血和供血相关选定数据。此外,还自愿开展了为期12个月的试点研究。记录了红细胞(RBC)浓缩物的数量,并每周计算库存情况。
2009年至2021年,RBC浓缩物的年供应量从468万降至343万,人均分配量从每1000名居民58单位降至41单位。在新冠疫情期间,这些数字没有显著变化。为期1年的试点项目数据占德国已发放RBC浓缩物的77%。O RhD阳性RBC浓缩物的百分比在35%至22%之间波动,O RhD阴性浓缩物的百分比在17%至5%之间波动。O RhD阳性RBC浓缩物库存的可用天数在2.1至7.6天之间变化。
所呈现的数据显示,11年间RBC浓缩物的年销售量有所下降,且在过去2年中没有进一步变化。每周对血液成分进行监测可发现RBC供应中的急性问题。密切监测似乎有帮助,但应与全国性供应策略相结合。
