Introduction: The COVID -19 pandemic has significantly impacted the healthcare system globally, including blood transfusion services. This has disrupted the traditional pattern of blood donation criteria, leading to changes in blood donor criteria, donor screening and donation procedures. The main aim of this study is to compare the Blood Donor Deferral patterns during Pre and Post COVID. Methods: This cross-sectional study was done at a tertiary care centre for a period of 2 year from Jan 2019 to Dec 2019 (Pre COVID) and Jan 2022 to Dec 2022(Post COVID). The Data for Donor deferral was compared for Pre-COVID and Post COVID period. Standard Operating procedures (SOP) based on national guidelines were used for donor selection and deferral. In addition, COVID-related deferrals were also incorporated. The donor deferral period for COVID vaccination was taken as 14 days as per the ICMR guidelines. Results:17807 and 18106 were registered during Pre and Post COVID time, 16489 and 16671 donors were accepted for donation. Deferral rate was 7.40% and 8.60% respectively in Pre-COVID and Post- COVID. Conclusion: The changes in donor eligibility criteria and deferral patterns that occurred as a result of the COVID-19 pandemic and the subsequent rollout of COVID-19 vaccines have important implications for the safety of the blood supply.
