Abstract

Bone marrow macroscopic examination remains one of the most difficult and subjective laboratory assessments in hematology. Only a few external quality assurance programs in the field are present worldwide. We have developed an external quality assurance program EQAhem that allows assessment of the whole process of bone marrow examination. The program participants assess blood and bone marrow smears from the patient, identify selected cells from photographs provided to them, and interpret the microscopic results. In this article, the results of the EQAhem program in Poland from 6 years are summarized. During this time, 62 labs were assessed in total, and positive results were achieved by 89.25 % labs, taking into account all tests. Correct responses with respect to the percentage of cell count were provided by ca. 77.5 % labs. Slightly worse results were obtained when megakaryocyte count and cell identification from photographs were tested. The worst results were obtained in case of dysplasia assessment and clinical interpretation of microscopic examination (54.1 and 58.6 % correct responses, respectively). EQAhem delivers precise information about the quality of bone marrow examinations performed in Poland and has a substantial educational value. We believe that after 6 years, EQAhem has significantly improved the quality of bone marrow microscopic examinations performed in Poland.
