Learning Objectives

  • After participating in this educational activity, participants should be able to:
  • Explain platelet refractoriness and etiologies.
  • Describe clinical and laboratory features of platelet refractoriness.
  • Describe transfusion support for platelet refractoriness.

Program Description: Platelet transfusion refractoriness is an increasing issue in heavily transfused patients such as patients with hematologic malignancies. The blood bank and HLA laboratory play an important role in assessing clinical refractoriness and helping clinicians determine whether there is an immune or non-immune etiology (or both). Dr. Peña will describe his institution’s approach to the platelet refractory patient.
