BACKGROUND: Febrile nonhemolytic transfusion reactions (FNHTRs) are the most common adverse reaction reported under the Haemovigilance Programme of India, and the use of leukodepleted blood products is recommended. The severity of the reaction may affect the morbidity associated with the reaction. This study aims to calculate the incidence of various transfusion reactions in our blood center and to evaluate the impact of buffy coat reduction on the severity of febrile reaction and other hospital resource-consuming activities. MATERIALS AND METHODS: It was an observational retrospective study in which all reported FNHTRs were evaluated during the period July 1, 2018–July 31, 2019. Patient demographic details, component transfused, and clinical presentation were analyzed to identify factors affecting the severity of FNHTRs. RESULTS: The incidence of transfusion reaction in our study period was 0.11%. Out of total 76 reactions reported, 34 (44.7%) were febrile reactions. Other reactions included allergic reactions (36.8%), pulmonary reactions (9.2%), transfusion-associated hypotension (3.9%), and others (2.7%). The incidence of FNHTR in buffy coat-depleted packed red blood cells (PRBCs) and PRBCs is 0.03% and 0.05%, respectively. FNHTRs are seen more in females with prior history of transfusion (87.5%) as compared to males (66.67%) (P = 0.046). We also found that FNHTRs are less severe with buffy coat-depleted PRBC transfusion than PRBC transfusion as mean ± standard deviation temperature rise was less in buffy coat-depleted PRBC (1.3 ± 0.8) than PRBC (1.74 ± 1.129). The febrile response to buffy coat-depleted PRBC transfusion occurred at higher volume (145 ml) transfusion than PRBC transfusion (87.2 ml), and it was statistically significant (P = 0.047). CONCLUSION AND SUMMARY: Leukoreduction remains the main modality to prevent FNHTR, but in developing countries like India, the use of buffy coat-depleted PRBC over PRBC can reduce the incidence and severity of FNHTR.
