Patient blood transfusion management: discharge hemoglobin level as a surrogate marker for red blood cell utilization appropriateness

BACKGROUND: Blood transfusion management strategies minimize transfusion‐associated risks, enhance outcomes, and reduce costs. We explored an association of discharge hemoglobin (Hb) with pretransfusion Hb, transfusion indications, and red blood cell (RBC) transfusions. We stipulate that patients with discharge Hb concentrations greater than 10.0 g/dL, or even 9.0 g/dL, received excessive RBC transfusions.
