Abstract

BACKGROUND: Transfusion-associated circulatory overload (TACO) is a growing concern in clinical practice. STUDY DESIGN AND METHODS: A case control study was performed at the Nîmes University Hospital, France. TACO cases occurring after RBC transfusion reported from January 1, 2014, to May 31, 2017, were included as cases. Four controls by case were randomly selected among the other RBC recipients on the same day. RESULTS: During the study period, 60 TACO diagnoses were reported for 37,029 transfused RBCs to a total of 8787 patients; 240 controls were included. The average rate of TACO was one case every 616 RBCs transfused. One in 146 transfused patients experienced TACO. TACO was associated with a higher 28-day mortality (22% vs. 11%; p = 0.003), and a longer hospital stay compared with controls (23.5 ± 19.6 days vs. 15.9 ± 20.1 days; p
