Adverse events (SEAR/SPEAR)
Every year, more than 21,000 volunteer donors are asked to donate blood stem cells to a patient they do not know. To ensure the continued viability of the global system using volunteer donors, donor health and safety are of critical importance. Because almost half of the blood stem cells collected from volunteer donors for transplantation cross international borders, optimal donor safety requires global strategies.
The WMDA has set up a central global reporting system for WMDA member organisations to report Serious (Product) Events and Adverse Reactions – S(P)EARs – to the WMDA. The aim of the S(P)EAR system is to gain insight in the occurrence of serious events and adverse effects in relation to blood stem cell donation by unrelated donors and blood stem cell collection/processing from unrelated donors.
The S(P)EAR Committee reviews all reported incidents once a week. If you have a rapid alert that you would like to share with the community quickly, we recommend sending a separate e-mail to the WMDA Office.
