• Rationale and Comments

    In asymptomatic (i.e., nonbleeding) pediatric patients with a platelet count > 10,000/mcL, transfusion is not clinically indicated unless signs, symptoms, or increased risk factors of bleeding are present. This practice is consistent with recommendations from the clinical guidelines of multiple associations (National Institute for Health and Care Excellence, British Society for Haematology, American Society of Clinical Oncology, and American Society of Hematology). The risk of spontaneous bleeding is low at platelet counts > 10,000/mcL. Unnecessary transfusions put patients at risk for transfusion reactions, alloimmunization, blood-borne infections, and refractoriness to future platelet transfusions. This recommendation does not apply in anticipation of an invasive procedure.
