AABB continues to work with facilities around the world to participate in national hemovigilance efforts. Through its expert committees, AABB collaborates with government agencies and international organizations to establish and promote standard definitions related to transfusion reactions. Additionally, AABB committees develop education and supports research to further the goals of hemovigilance.
The AABB Common Transfusion Reaction Reporting Form is intended for use by hospitals and blood centers for communicating information about transfusion reactions to the blood supplier, particularly when there are multiple suppliers to the hospital transfusion service. The form is intended to streamline the process for hospitals and provide complete information for blood suppliers when investigating transfusion reactions. The AABB Donor Hemovigilance Working Group and Hemovigilance Committee recently reviewed and updated the form, after the end of a successful first year use.
The revised transfusion associated circulatory overload (TACO) definition (2018) developed and validated by the International Society of Blood Transfusion (ISBT) working party on Haemovigilance in collaboration with the International Haemovigilance Network (IHN) and AABB, is now available online and results of the formal validation have been published (The Lancet Haematology, 2019). The revised definition is applicable to cases that occur up to 12 hours after transfusion. Combinations of signs and symptoms which can add up to meet the surveillance diagnostic criteria will help qualify cases where there may be no chest x-ray and/or record of elevated BNP concentrations as TACO. Notes on signs and symptoms and didactic table listing of key features has been added to assist in making diagnosis. The revision group emphasizes that the chief priority is to adopt standard reporting criteria, which will enable professionals to raise awareness of TACO and lead to improved reporting, research and reduction of transfusion complications.
