The aim of this study was to evaluate transfusion-related adverse reactions (TRARs). In this study, all adverse reactions (ARs) related to blood/blood product transfusions conducted between 01.01.2022 and 31.03.2023 at the Health Sciences University Türkiye, Adana City Training and Research Hospital were evaluated. In total, 97,926 records of blood and blood component transfusions were evaluated during the study period. The distribution of blood components used was as follows: 57,066 (58.2%) red blood cell concentrates, 27,345 (28%) fresh frozen plasma, 12,282 (12.5%) pooled platelet concentrates, 564 (0.6%) apheresis platelet concentrates, and 669 (0.7%) cryoprecipitates. In total, 40 AR reports were associated with transfusions. The probability levels of the relationship degrees of reactions for these 40 cases were as follows: 2 cases; not likely (5%); 32 cases; likely (80%); 2 cases; highly likely (5%); and 4 cases, unassessable (10%). All unwanted reactions were acute, and there were no delayed reactions. No transfusion reaction (TR) leading to death occurred. Of the patients who developed reactions, 60% (n=24) were female, and 40% (n=16) were male. The ages of patients with unwanted reactions ranged from 2 to 86 years, with a median age of 33. Among the cases with unwanted reactions, 8 were children (20%) and 32 were adults (80%). In our study, the frequency of allergic TR was 8.1 per 100,000 children and 32.6 per 100,000 adults. A statistically significant difference in the distribution of blood component types among cases based on the types of unwanted reaction was observed (p=0.003).
In this retrospective evaluation of 15 months of data from a single center, 97,926 blood component transfusions were performed, and the prevalence of TRAR was 40.8 per 100,000 blood components.
