Abstract

Introduction

The discard rate of blood services as a crucial quality metric for monitoring and enhancing blood safety within blood bank operations. This study investigated the prevalence and underlying causes of discarded blood and its associated components at a blood center in China.

Materials and Methods

This retrospective analysis examined data pertaining to discarded blood and its components from 2019 to 2022. Information was retrieved from the blood center's electronic blood information management system.

Results

A total of 71,346 units of whole blood and blood components (representing a discard rate of 2.34%) were discarded. The discard rates exhibited variation across different blood components: whole blood (0.15%), red blood cells (2.24%), fresh frozen plasma (4.20%), frozen plasma (5.05%), cryoprecipitate antihemophilic factor (0.91%), platelets (0.33%), and washed red blood cells (0.03%). Statistical analysis revealed a significant association (P < 0.05) between the reasons for discarding blood and the actual discard events.

Conclusion

This study presents a comparative analysis of discard rates and their corresponding justifications within a single blood center in China. The findings contribute to the advancement of quality control measures for blood and its components within blood service operations.

2019-2022年中国单采血站血液及其成分弃血率及原因分析

导言血液废弃率是监测和提高血库运行中血液安全的重要质量指标。本研究调查了中国某血站废弃血液及其相关成分的发生率和根本原因。材料与方法本回顾性分析调查了 2019 年至 2022 年废弃血液及其成分的相关数据。结果共废弃了 71346 单位全血和血液成分（废弃率为 2.34%）。不同血液成分的废弃率存在差异：全血（0.15%）、红细胞（2.24%）、新鲜冰冻血浆（4.20%）、冰冻血浆（5.05%）、低温沉淀抗血友病因子（0.91%）、血小板（0.33%）和洗涤红细胞（0.03%）。统计分析显示，弃血原因与实际弃血事件之间存在明显关联（P < 0.05）。研究结果有助于推进血液服务业务中血液及其成分的质量控制措施。
