Abstract Pathway



George Mastoras (MD, FRCPC) is an Attending Physician in the Department of Emergency Medicine at University Health Network (UHN) and Assistant Professor of Emergency Medicine in the Department of Medicine, University of Toronto. With particular expertise in resuscitation medicine and simulation-based health professions education, Dr. Mastoras has a keen interest in optimizing Emergency Department care for critically ill patients. His academic work brings together the realms of simulation, emerging technologies, team training and quality improvement to achieve this goal. In addition to an active clinical and academic practice, Dr. Mastoras co-chairs the UHN Acute Resuscitation Committee, co-leads the ECPR working group, and is the Research/QI Lead for the EM Simulation program. He is an enthusiastic clinical teacher, mentor to numerous medical trainees, and has published and lectured nationally on a range of topics in patient safety, simulation, and resuscitation.
