Live Program Date: Wednesday, July 10, 2019 - On-Demand Available
Master Program Number: 19EL-450 (see program format numbers below under Registration)
Educational Track: Technical/Clinical
Topic: Transfusion Medicine
Intended Audience: Donor Recruitment Staff, Hospitals, Hospital Blood Banks, Laboratory Staff, Managers/Supervisors, Medical Directors, Nurses, Physicians, Resident/Fellow, Students (MD, MT, SBB), Technologists, Transfusion Safety Officers
Teaching Level: Intermediate to Advanced
Director/Moderator: Kerry L. O’Brien, MD, Medical Director Blood Bank, Beth Israel Deaconess Medical Center, Boston, MA
Speaker: J. Ryan Peña, MD, PhD, MS, D(ABHI), Medical Director HLA Laboratory, Beth Israel Deaconess Medical Center and Assistant Professor Pathology at Harvard Medical School, Boston, MA
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.
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.
