Prospective multicenter study of 9,482 total hip and knee arthroplasty patients across 330 U.S. surgeons, examining what predicts allogenic transfusion, how efficiently predonated autologous blood is used, and what complications are associated with different transfusion types.
When planning blood management for total joint arthroplasty, check the baseline hemoglobin before any donation: patients at or below 130 g/L are at highest risk for allogenic transfusion and paradoxically most vulnerable to iatrogenic anemia from predonation itself — these patients warrant preoperative optimization (iron, erythropoietin) rather than reflexive predonation.
Universal autologous predonation for all comers is inefficient; primary unilateral knee patients waste over half their donated units, while revision hip patients face a 21% chance of needing allogenic blood anyway.
