These patients are of importance, as they are large consumers of blood products and likely have different characteristics and outcomes than nontransfused patients and patients transfused with only one blood component type. Our study aimed to determine the prevalence of multicomponent transfusion at a large multisite academic center, as well as the patient characteristics and outcomes associated with multicomponent transfusion.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>A retrospective cohort study of transfused adult inpatients at the Ottawa Hospital between 2007 and 2017 was performed. Eligible transfusions were red blood cells (RBCs), platelets, plasma, cryoprecipitate, and\/or fibrinogen concentrate. Descriptive analyses were done to determine multicomponent transfusion prevalence. Patient characteristics and outcomes associated with multicomponent transfusion were assessed using multivariable regressions.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Of 55,719 adult transfused inpatient admissions, 25% received a multicomponent transfusion. Multicomponent transfusion prevalence was highest in hematology (51%), cardiac surgery (45%), and critical care (40%) patients. Multivariable regression analysis showed that compared to RBC\u2010only transfusion, multicomponent transfusion was associated with increased odds of in\u2010hospital mortality (odds ratio, 3.48; 95% confidence interval [CI], 3.26\u20133.73), greater odds of institutional discharge as opposed to discharge home (odds ratio, 1.22; 95% CI, 1.15\u20131.30), and a 1.58 time increase in duration of hospitalization (95% CI, 1.54\u20131.62).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Multicomponent transfusion recipients make up a large proportion of transfused patients and have poorer outcomes.
