OBJECTIVE: The transfusion of older packed red blood cells (PRBC) may be harmful in critically ill patients. We sought to determine the association between PRBC age and mortality among trauma patients requiring massive PRBC transfusion. Competing interests: JRH receives patent royalties from the United States Army and the University of Maryland for improved red blood cell storage solutions. The rest of the authors declare that they have no competing interests.

CC was rare compared to LC. CC was associated with poor outcomes and impairment of both clotting factor and platelet-mediated coagulation components.

TNT complements population screening by more directly targeting high-risk individuals and by expanding the population receiving testing. Information from existing healthcare services could be used to seed TNT programs, or TNT could be implemented within healthcare settings. Research evaluating multi-component, multi-venue HIV detection is necessary to maximize complementary approaches while minimizing redundancy.
