采供血过程中异常血液报废事件的分析与防控对策研究OA

Objective To analyze the characteristics and key risk factors of abnormal blood disposal throughout the 2024-2025 blood collection and supply process based on nationwide multi-site monitoring data,develop a comprehensive prevention and control strategy across the entire chain,reduce preventable blood waste,and ensure clinical blood safety.Methods According to the Guidelines for Haemovigilance(T/CSBT 001-2026),we extracted 74 cases of abnormal blood disposal events reported by the China Blood Transfusion Association's Blood Safety Monitoring System from January 1 2024,to December 31 2025,and conducted descriptive statistical analysis on the distribution of events,types of deviations,root causes,and classifications of disposal manifestations.Results A total of 664 adverse events related to blood collection and supply were reported over two years,with 74 cases involving discarded abnormal blood units,accounting for 11.1%of the total.Among these,blood component preparation(40.5%)and blood collection(37.8%)remained traditional high-risk stages.The proportion of blood waste occurring during storage,distribution,and transportation increased from 7.7%in 2024 to 34.3%in 2025.Deviations from standard operating procedures(SOP)by personnel were the primary cause,ac-counting for 74.3%of cases.Discarded blood units were categorized into four types:compromised closed blood bag systems(40 cases),mainly due to inadequate heat sealing,physical damage,or dropped bags;blood out of the cold chain(12 ca-ses),primarily resulting from blood being left at work sites;imbalanced proportion of preservation solution(10 cases),mostly caused by blood collection volumes exceeding the standard capacity of blood bags;and other causes(12 cases).Conclusion Human operational errors are the core cause of abnormal blood waste.The collection and preparation stages have long been at high-risk,and the risks in the storage and transportation stages have been increasing year by year.We should focus on standardizing personnel management,improving specialized operation norms such as heat sealing,transpor-tation,and storage,establishing a full-process intelligent cold chain monitoring and multi-node visual verification mecha-nism,and systematically reducing the occurrence rate of abnormal blood waste through a closed-loop quality intervention sys-tem,thereby improving the utilization efficiency of voluntary blood donation resources.
