Transfusion
-
The red blood cell (RBC) transfusion trigger is a major driver of transfusion practice and affects health care costs and in some instances patient outcomes. Reducing the transfusion threshold will decrease RBC utilization and hospital costs. ⋯ A Hb level of 7 g/dL is the transfusion threshold which is being adopted by many hospitals. Institutional culture change to a Hb level of 7 g/dL can be implemented with the right champion when endorsed by upper echelon medical leadership and hospital administration.

The evidence supporting plasma transfusion as a means to restore hemostatic control and prevent or treat bleeding is weak, leading to uncertainties as to which proteins affect the therapeutic quality of plasma. Some regulators focus on coagulation Factor (F)VIII activity, but whether this measure reflects overall transfusable plasma efficacy is questionable. We developed a mouse model of coagulopathy in which bleeding outcomes were responsive to plasma transfusion and addressed the relative contributions of FVIII and fibrinogen (Fg) to plasma quality. ⋯ The content of Fg, but not FVIII, determined the efficacy of plasma transfusion in coagulopathic mice.
