Evaluation of crossmatch-to-transfusion ratio, frequency and types of acute reactions in the blood bank

Introduction: This study aimed to determine crossmatch-to-transfusion (C/T) ratio and the frequency of acute reactions to transfusion in the blood bank of Shahid Beheshti Hosptial, Hamedan.Material and Methods: This cross-sectional descriptive study was performed on all transfusions in Shahid Beheshti Hospital, Hamedan, from March ۲۰, ۲۰۲۲ to March ۲۱, ۲۰۲۳. The data source was the previously filled transfusion forms. C/T ratio was calculated by dividing the number of crossmatched units to the number of transfused units. Also, the incidence of fever, chills, pruritus and redness of the skin, skin rash, back pain, hypotension, dyspnea, chest pain, hematuria, and cold sweat during or after transfusion were evaluated. Gender, blood group, and Rh of the blood recepients were also noted.Results:Out of ۳,۶۳۰ blood requests, ۵۹.۱% were from males and ۹۱.۳% Rh-positive. Blood groups were ۳۳.۹% A, ۲۱.۹% B, ۶.۹% AB, and ۳۷.۷% O. A total of ۶,۹۰۶ units were crossmatched, with ۶,۶۱۱ transfused and ۲۹۵ unused—mainly from urology, emergency, and other wards. The overall C/T ratio was ۱.۰۴, with the highest in Shahrivar (۱.۲۱) and lowest in Khordad (۱). Common transfusion reactions included chills (۰.۳%), fever, and dyspnea (۰.۱۹%), with no cases of back pain, chest pain, or cold sweat.Conclusion: It can be conferred that the status of blood usage was good compared to the global standards and there were minimal acute reactions to transfusion. These results could influence transfusion practices or patient safety measures in the hospitals or similar settings.
