The impact of COVID-19 on blood safety and availability in the Islamic Republic of Iran

Background: The COVID-19 pandemic has affected blood inventory and donation worldwide. The Islamic Republic of Iran was among the first countries to report the COVID-19 pandemic and it faced a significant blood shortage during the first weeks of the pandemic. Aims: We aimed to evaluate the impact of COVID-19 pandemic on the number, type, and safety of blood donations, comparing the periods before and during the pandemic.Methods: This retrospective study evaluated data from all volunteers who attended the blood transfusion centres in the Islamic Republic of Iran from March to December 2020 (during the COVID-19 pandemic) and during the same period in 2019, i.e. pre-pandemic. Data on the number of blood collections, confirmed transfusion transmissible infection marker test results, and donor demographic information were collected from the Iranian Blood Transfusion Organization integrated donor database.Results: Total blood donations decreased by 8.38%. The number of first-time, lapsed, and female blood donors increased by 4.41%, 0.17%, and 0.90% respectively. Regular blood donation decreased by 4.58%. The distribution of the 3 main blood products, red cell concentrate, frozen fresh plasma and platelets, decreased by 7.86%. All changes were statistically significant. The prevalence rates of hepatitis C virus and hepatitis B surface antigen increased significantly during the pandemic.Conclusion: COVID-19 had a negative effect on blood safety and availability in the Islamic Republic of Iran. To improve blood supply and enhance regular blood donation, the Iranian Blood Transfusion Organization needs to reassure blood donors of the safety and hygiene measures being observed at blood collection sites.
