Patient Hemovigilance

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 Center for Patient Safety, a component Patient Safety Organization (PSO) of AABB, will be discontinued April 30, 2019 (see letter from AABB CEO, Debra BenAvram to PSO participants). AABB encourages all facilities to continue to report to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) hemovigilance module.

Current projects related to patient hemovigilance include:

Proposed Revised TACO Definition

The revision of the ISBT/IHN definition for transfusion-associated circulatory overload (TACO) was launched in 2013 at the request of members. The revision group recognizes 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. The revision group includes representatives from AABB, and this opens possibilities for harmonization. In future, the criteria may need to be adjusted in the light of accumulating evidence.

Common Transfusion Reaction Reporting Form

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 form and FAQ were developed by AABB hemovigilance committees.
