[Patient blood management (part 1) - patient-specific concept to reduce and avoid anemia, blood loss and transfusion]. / Patient Blood Management (Teil 1) - Individuelles Behandlungskonzept zur Reduktion und Vermeidung von Anämie, Blutverlust und -Transfusionen.

Patient blood management (PBM) is a patient-specific multidisciplinary, multimodal, evidence-based concept to appropriately conserve and manage a patient's own blood as a vital resource. PBM is based on 3 pillars: the first is the optimization of the patient's endogenous red cell mass, the second is the minimization of bleeding and blood loss and the third involves harnessing and optimizing the patient-specific physiological tolerance of anemia, including adopting more restrictive transfusion thresholds. PBM primarily identifies patients at risk of transfusion and provides a management plan aimed at reducing or eliminating the need for allogeneic transfusion, thus reducing the inherent risks, inventory pressures and the escalating costs associated with transfusion. PBM is applicable to surgical and medical patients. The application of PBM systematically reduces the impact of 3 major contributors to negative outcome: anemia, blood loss and transfusion.
