Establishment and operation of external quality assessment system for blood cell morphology
摘要
Abstract
Objective To establish an external quality assessment(EQA)system for blood cell morpholo-gy,and to evaluate the cell morphology recognition capability of laboratory personnel in primary hospitals.Methods The typical and representative pictures of cells or substances in peripheral blood smears were select-ed by the graphic imaging system to establish the blood cell morphology atlas database,the EQA system of blood cell morphology was constructed by combining with EQA management network platform,and the twice EQA works of blood cell morphology,a total of 20 quality evaluation pictures,were carried out in more than 160 basic hospitals of Center for Clinical Laboratory of Xinjiang Production and Construction Corps during 2023.Results The constructed atlas library covered 78 types of blood cells with a total of 1 520 images,inclu-ding the red blood cell system,granulocyte system,lymphocytes and plasma cells,monocyte system,megakaryocytes and platelets,etc.The EQA work of blood cell morphology in 2023 conducted the data repor-ting,quality evaluation results release,summary analysis,etc.There were 27 laboratories(16.67％)achieving the full marks in the twice EQA works.The number of laboratories that passed the first and second EQA was 123(75.46％)and 138(85.18％)respectively,and the difference between the two qualified rates was statisti-cally significant(P＜0.05).Conclusion The more perfect EQA system for blood cell morphology has been constructed by this study and was better applied in the evaluation of cell morphology recognition capability of the inspectors in the basic hospitals.Meanwhile,it also reflects the urgent need to improve the blood cell mor-phology recognition ability of laboratory personnel in primary hospitals.关键词
