In an upcoming AABB/Transfusion Twitter chat, Richard M. Kaufman, MD, and Jeannie Callum, MD, FRCPC, will lead a discussion on "Patient Identification: A Cornerstone of Transfusion Safety." The Twitter chat, which will focus on strategies to prevent errors leading to ABO mistransfusion, is scheduled for Tuesday, March 26, at 1:00 pm ET. Kaufman recently co-authored a study on pretransfusion sample labeling. The study found that using electronic patient identification at the time of sample collection was associated with five-fold fewer wrong-blood-in-tube errors compared with traditional manual patient identification. Callum's current research focuses on the implementation of positive patient identification (mobile handheld computers) for transfusion to reduce the risk of acute hemolytic transfusion reactions.
