Languages spoken: English

  • Dr. Metcalf is Section Chief of Transfusion Medicine, Medical Director of the Transfusion Service, Associate Professor of Pathology, and Inpatient Chief Value Officer for the Department of Pathology at the University of Utah Health and ARUP Laboratories. He completed a residency in Anatomic and Clinical Pathology and a fellowship in Transfusion Medicine at Stanford University and is board certified in these disciplines. He also has expertise in quality management and is a Certified Quality Auditor.

    Dr. Metcalf practices transfusion medicine and his specific interests include data-driven/informatics approaches to patient blood management, quality management, and innovation. He was previously Assistant Professor at the University of Washington where he helped build a new FDA-registered hospital-based transfusion service laboratory. He was recruited to the University of Utah and ARUP Laboratories in 2017. His research interests include the use of advanced data visualization to improve understanding of patient blood management (PBM) clinical practice quality, safe and effective use of artificial intelligence in healthcare, evidence-based clinical decision making, and data-driven approaches to improve our understanding of risks associated with blood transfusion. He is co-inventor of a novel advanced data visualization tool that evaluates PBM practice.

    Dr. Metcalf is Chair of the Association for the Advancement of Blood and Biotherapies (AABB) Clinical Transfusion Medicine Committee, a member of the AABB Patient Blood Management Standards Committee, and a member of the College of American Pathologists (CAP) Transfusion, Apheresis, and Cellular Therapy Committee. He is active in Transfusion Medicine education and received the department's Outstanding Teaching Award for Clinical Pathology faculty in 2020.
