Abstract
ObjectivesStandardized criteria guaranteeing harmonized interpretation among morphologists in the provision of morphology results represent an important tool to be adopted for risk management and patient safety. Aim of this work is to assess agreement among morphologists in the microscopic evaluation of the peripheral blood smear. Methods17 morphologists participating in the external quality assessment (EQA) program individually evaluated the blood smear and recorded the results using a personal username and password. Agreement among operators was evaluated. ResultsThe overall agreement rate in microscopic differential was 95% in 2016 and 97% in 2017 (acceptance limit 90%), with 6/120 and 4/120 incongruent results, respectively. The agreement for the diagnostic hypothesis was satisfactory with a full agreement being reached in 5 out of 16 cases. ConclusionsThe creation of a tool to assess the agreement of readers providing morphological evaluations is a valuable step forward in ensuring patient safety and quality laboratory medicine.
