Transfusion-associated circulatory overload is a leading cause of transfusion-related adverse events. The frequency and risks for transfusion-associated circulatory overload in ambulatory haematology patients are not known. ⋯ Transfusion-associated circulatory overload occurs infrequently haematology patients receiving ambulatory blood transfusions. To our knowledge, this is the first study to report on occurrence and risk factors for circulatory overload in ambulatory transfusions. This study provides vital baseline data for future prospective studies on this important aspect of haemovigilance.
