Fatal ABO-incompatible (ABOi) transfusion is one of the most common causes of transfusion-related death, but its reporting has been limited in Korea. We comprehensively reviewed ABOi transfusion events in Korea by analyzing cases reported in literature, Korean hemovigilance system (KOHEVIS) annual reports, and written judgments. Written judgments were assessed using a written judgment management system or a comprehensive legal information system. We found nine cases of ABOi transfusion events in written judgments (from 1953 to 2019), 16 in the KOHEVIS (from 2008 to 2018), and nine in published reports (from 1978 to 2019). One case was found in all three sources. Overall, we found 32 cases of ABOi transfusion events. Four cases died and 23 survived, while the outcomes for five were unavailable. ABOi transfusion errors occurred at the administration (50%, 16/32), sample (13%, 4/32), and testing (9%, 3/32) stages. The causes of errors were unavailable for nine cases (28%, 9/32). We report the status of ABOi transfusions in Korea and expect our results to contribute to the prevention of adverse reactions due to ABOi transfusion.
