BACKGROUND AND OBJECTIVES: Blood donor deferral is an essential tool for blood safety. The ongoing COVID-19 pandemic has adversely affected blood transfusion services all over the world. But its impact on donor deferral rate and the pattern is unclear in light of the new donor deferral policy due to the COVID-19 pandemic.
MATERIALS AND METHODS: This retrospective study was divided into pre-COVID and COVID (15 March 2019-14 March 2021). All the deferred donors were divided into six different categories: (1) medical causes, (2) surgical causes, (3) drugs and vaccination, (4) risk of transfusion-transmitted diseases, (5) miscellaneous causes and (6) flu-like symptoms. In addition, COVID-related deferrals were also incorporated. All these above categories along with the donor demography were analysed by SPSS software version 25.
RESULTS: The donor deferral rate was 17.03% and 12.74% during the pre-COVID and COVID periods, respectively. During the pre-COVID period, Category 3 deferrals and during COVID period, Category 6 deferrals were significantly higher. A reversal in pattern with increased blood pressure (40.2% vs. 24.04%) over-riding low haemoglobin (34.77% vs. 55.5%) was noted in the Category 1 deferral during the COVID period. Category 1 deferral was more in middle-aged adults as compared to young and old adults (p < 0.05). Among middle-aged adults, deferral due to flu-like symptoms was also significantly more during the COVID period (p < 0.05).
CONCLUSION: COVID-19 significantly affected the donor pool and changed the pattern of donor deferral. Understanding donor deferral patterns may help in identifying targeted donor populations and planning donor recruitment strategies in future pandemic crises.
