Associate Professor of Emergency Medicine
Emergency Medicine

Overview


Rebecca Theophanous, MD, MHSc, FAEMUS is an Emergency Ultrasound Faculty at Duke University Hospital and the Durham VA Healthcare System. 

She is actively involved with clinical ultrasound education, teaching residents and students on shift, performing weekly ultrasound image review, presenting monthly advanced ultrasound talks, and teaching at monthly resident simulation sessions.

Her first-author publications investigate the diagnostic utility and accuracy of 3D ultrasound for assessing ocular complaints, and she developed a point-of-care ultrasound implementation intervention for VA clinicians (funded by an SAEMF/AEUS grant in 2022-2023). Furthermore, she completed a Master of Health Sciences degree through Duke’s Clinical Research Training Program and served as site PI for the Reason3 POCUS in cardiac arrest trial. Her recent SAEM ARMED MedEd studies involve implementation and testing of POCUS simulation-training methods (nerve block training funded by SAEMF), resident and faculty development, and POCUS competency testing.

Dr. Theophanous leads as an AAEM-EUS councilor and SCUF Education fellowship curriculum subcommittee lead. She has presented both didactic and research-based talks at national conferences and has experience writing POCUS guidelines and policy on her hospital’s POCUS taskforce. Finally, she is a reviewer for multiple medical journals, including for the Journal of Ultrasound in Medicine.
