RBC transfusion, however, can be associated with adverse events including transfusion reactions, acquiring transmissible disease, and delayed recovery. Factors associated with avoidance of transfusion are not well documented.<\/jats:p><jats:p><jats:bold>STUDY DESIGN AND METHODS:<\/jats:bold> Data concerning RBC transfusions between Day\u20030 and Day\u2003+30 were analyzed for patients undergoing HSCT at a single Canadian transplant center between January 2002 and December 2007.<\/jats:p><jats:p><jats:bold>RESULTS:<\/jats:bold> Of 555 patients undergoing HSCT with complete RBC transfusion data, 59 patients (10.6%) did not require RBC transfusion in the first 30 days after HSCT. Univariate analysis showed no significant difference in age, graft source, donor type, or conditioning regimen between transfused and nontransfused patients. Factors that were significantly associated with avoidance of transfusion included male sex (p\u2003=\u20030.0013), diagnosis, specifically plasma cell dyscrasias (p\u2003&lt;\u20030.0001), early\u2010stage disease (p\u2003=\u20030.006), and higher baseline hemoglobin (Hb) at time of transplant (p\u2003&lt;\u20030.0001). In multivariate analysis, higher pretransplant Hb, male sex, and early\u2010stage disease remained significantly associated with avoidance of RBC transfusion. Pretransplant Hb correlated inversely with the number of RBC transfusions (r\u2003=\u2003\u22120.89).<\/jats:p><jats:p><jats:bold>CONCLUSION:<\/jats:bold> Increased pretransplant Hb, male sex, and early\u2010stage disease are associated with avoidance of RBC transfusion after HSCT. Interventions aimed at improving pretransplant Hb levels require further
