目的 分析抽检血液成分关键指标结果并采用趋势分析方法进行评估。方法 收集整理2015—2017年每月1次的8种血液成分质量控制的检测数据,选择关键指标并制作折线图,联合行动限和警戒限进行趋势分析。结果 未能100%达到GB 18469—2012《全血及成分血质量要求》的项目包括悬浮红细胞容量及Hct、单采血小板及浓缩血小板血小板含量、新鲜冰冻血浆及冷沉淀VIII因子含量。新鲜冰冻血浆及冷沉淀的VIII因子含量项目分别出现10次和5次偏离数据;单采血小板及浓缩血小板的血小板含量项目分别出现3次和4次偏离数据。结论 根据血液成分的关键指标结果进行趋势分析发现问题,主动寻找原因并及时采取相应措施,是确保血液质量的一种有效手段。

Objective To analyze and evaluate the results of key indexes of the blood component by trend analysis. Methods Collected and arranged the data of eight kinds of blood component quality control,which was did once month in 2015-2017.Selected the key indexes and made the line charts.Allied with the action limits and warning limits for trend analysis. Results The key indexes could not 100% meet the “Quality requirements for whole blood and component blood”,including capacity and Hct of suspended red blood cell,platelet content of apheresis platelets and platelets concentrate,factor VIII content of fresh frozen plasma and cryoprecipitate.The factor VIII of fresh frozen plasma and cryoprecipitate showed ten and five deviation data, respectively, the platelet content of apheresis platelet and platelets concentrate showed three and four deviations, respectively. Conclusion It's an effective way to ensure blood quality by trend analysis based on the results of key indexes of blood components, and actively find the cause and take corresponding measures in time.
