Patient Blood Management (PBM), also called blood utilization management (BUM),[1] is a multidisciplinary, evidence-based approach to optimizing the care of patients who might need a blood transfusion.[2][3] Blood management programs aim to minimize inappropriate transfusions and decrease the need for transfusions overall, with the goal of improving patient safety, reducing costs, and maintaining the supply of donated blood.[1][4] Some strategies to accomplish this include ensuring that anemia is treated prior to a surgical operation, using surgical techniques that limit blood loss, and returning blood lost during surgery to the patient via intraoperative blood salvage
