Background and ObjectivesThe competent authority (CA) responsible for external inspections of Polish blood establishments (BEs) and supervision of the quality system is the Institute of Haematology and Transfusion Medicine (IHTM). Before the implementation of the European Blood Inspection System (EuBIS) classification of non‐compliance, the IHTM inspections were conducted according to national guidelines and the non‐compliance‐related recommendations were based on the inspectors' own experience and interpretation of the observed problems. Since 2009, IHTM inspections were already performed according to EuBIS guidelines. The study assessed the impact of the EuBIS classification on the IHTM recommendations. We assumed that the implementation of consistent assessment criteria contributed to the upgrading of the quality of BE inspections.Materials and MethodsBE‐inspection protocols; 30 from 2009 to 2010 and 61 from 2016 to 2019. Non‐compliance‐related recommendations were classified according to the seriousness of non‐compliances (critical, major, other significant, and observation) and also to the area of BE activity (documentation, organisation of work, qualification and validation, pathway from donor qualification to blood component‐issue, quality control of blood components, adverse events and reactions).ResultsThe recommendations mostly referred to document‐keeping and work organisation and were distributed as follows: 2009–2 critical (others unclassified), 2010–1‐13 major, 4–25 other significant and 1–7 suggestions, 2016–2019–3‐9 critical, 90–196 major, and 157–297 other significant as well as 14–22 suggestions.ConclusionPolish BEs still require: integrated document management, analysis of IHTM recommendations, implementation of corrective and preventive measures and personnel training in identifying similar non‐compliances in other procedures.
