This analysis focused on three objectives: 1) to measure packed red blood cell (pRBC) use across different critical care settings; 2) to characterize transfused and nontransfused critically ill patients; and (3) to identify potential predictors of transfusion use. ⋯ Multiple factors increased the likelihood of pRBC use in ICU patients. In addition, pRBC transfusion was associated with increased length of stay. Clinicians should evaluate the risk-benefit ratio and consider interventions to limit any unnecessary pRBC use in the critically ill.
