Blood component transfusion is a frequently prescribed intervention in healthcare that depends on the availability of a limited and expensive resource. The transfusion of blood products may be life-saving, but it is not without risk. Society guidelines and clinical trials guide transfusion decisions regarding transfusion thresholds, as well as the appropriateness of prophylactic v. therapeutic transfusion strategies. This review provides a practical and evidence-informed approach to the transfusion of red blood cells and platelets in commonly encountered clinical settings.
