Objective. The study aimed to determine the impact of the COVID-19 pandemic on local blood supply management in the Davao Region, Philippines from 2019 to 2021 through the analysis of trends in blood supply in Davao Region, Philippines.

Methodology. Secondary data from two blood centers in the Davao Region for the years 2019 to 2021 were used to determine the trends on blood donation supply. To evaluate trends, the overall number of blood donors and the quantities of various types of blood components in whole blood, packed red blood cells (PRBCs), fresh frozen plasma (FFPs) and platelet concentrate have been compared between pre-pandemic, pandemic periods and as restrictions eased.

Results. A substantial decrease of 51.6% in the number of blood donors was seen during 2021 in comparison with 2019. The trend in collection by blood components also showed a significant trend from 2019 to 2021, whole blood (200.8%), packed RBCs (37.1%), fresh frozen plasma (113.6%). While the platelet concentrate supply declined by 34.9% from 2019 to 2020, an increase of 10.7% was noted onwards to 2021.

Conclusion. The results demonstrate that during the COVID-19 pandemic, there was a major reduction in donation and supply of blood. The challenges faced by blood banks in ensuring a stable and sufficient blood supply are highlighted by the decrease in the number of donors and by the different trends in the supply of blood components. The targeted efforts to promote blood donation and enhance the resilience of the blood supply during and after the pandemic is important.
