Abstract
INTRODUCTION: As coronavirus disease-2019 (COVID-19) spread worldwide and social restrictions were intensified, difficulties in blood supply were expected to result in a shortage of blood donors, logistic issues and a change in blood consumption. Consequences could be detrimental to the meeting of the blood supply demand, especially in a decentralized blood bank in the State of São Paulo responsible for providing blood to more than 100 hospitals, mostly of the public health system. Aiming to minimize negative effects and focusing on maintenance of the blood supply, a different approach was discussed and adopted. MATERIALS AND METHODS: Briefly, strategies were related to monitoring and promoting measures to achieve a positive RBC unit balance. Thus, the number of donors, transfusions, RBC unit inventory, RBC unit loss and RBC units within up to 5 days from the expiration date were evaluated. RESULTS: Several strategies were adopted to ensure sufficient availability of RBC units: blood donation was improved with social media and extra blood collections, a restrictive transfusion protocol was implemented, a new logistic process to use RBC units closer to the expiration date was established and non-isogroup transfusions were avoided. CONCLUSION: Altogether, described strategies were crucial to optimize blood storage during the pandemic. Investing in monitoring and logistics contributed to a positive RBC unit balance and conserving these strategies could be useful.
