2022年河北省血站质控实验室室间质量评价——HeBEQA项目回顾性分析

External quality assessment of laboratories in blood stations of Hebei Province in 2022:a retrospective analysis of HeBEQA project

目的 基于河北省省内各血站形成可比口径的愿望,对省内12家血站开展质控实验室室间质量评价项目,以探讨检测的准确性与可比性,提高检测能力和质量管理水平。方法 参照国家卫生健康委临床检验中心的实验室室间质评活动检测规则,结合质评品样本的说明书操作规范,参评实验室按实验室日常的检测流程进行检测。设置的质量指标项目有血细胞计数(WBC、RBC、Hb、HCT、MCV、MCH、MCHC、PLT 8项)、生化项目(总蛋白含量1项)、凝血项目(纤维蛋白原含量、Ⅷ因子含量2项)。结果 各单位在实验室人员操作、仪器设备维护保养、试剂批间差影响等方面仍存在问题,尤其在生化项目和凝血项目上体现明显。生化项目合格率最低,仅为72.75%。血细胞计数的合格率最高,达98.75%。结论 随着本年度项目的逐步推进,各单位质控实验室的日常血液抽检的质量监测水平得到了提高。但仍需及时发现和总结不足,向高标准实验室看齐,在省内血液质量控制方面达成一致。

Objective To conduct the laboratory quality assessment between 12 blood stations in Hebei province,analyze the results and explore the accuracy and comparability of testing,so as to improve the level of testing ability and quality management.Methods With reference to the external quality assessment rules of National Center for Clinical Laboratories and combined with the instructions of quality assessment samples,daily testing process of the laboratories were assessed.The quality indicators include blood cell count(WBC,RBC,Hb,HCT,MCV,MCH,MCHC and PLT),biochemical items(TP)and coagulation parameters(FIB and FⅧ).Results There are still problems in laboratories in terms of personnel operation,instrument maintenance and the impact of different reagent batches,especially in biochemical items and coagulation parameters.The pass rate of biochemical items was the lowest,only 72.75%,and that of blood cell count was the highest,reaching 98.75%.Conclusion With the progress of the project,the quality monitoring level of daily blood sampling tests in the quality control laboratory of each blood station has been improved.However,it is still necessary for each laboratory to improve the testing ability and quality management to a higher level in Hebei.
