Karen Burns


Scientist, Li Ka Shing Knowledge Institute


Dr. Karen Burns practices critical care medicine at St. Michael’s Hospital in Toronto. She is an Associate Professor of Medicine at the University of Toronto, a Clinician Scientist at the Li Ka Shing Knowledge Institute, and an Associate Member of the School of Graduate Studies with the Institute of Health Policy Management and Evaluation (University of Toronto) and the Department of Clinical Epidemiology (McMaster University).

Dr. Burns’ research program focuses on evaluating strategies to liberate critically ill patients from mechanical ventilation and characterizing practice variation in weaning critically ill adults from ventilators. Her research program includes large scale observational studies, national and international weaning surveys, meta-analyses, and randomized trials comparing different weaning strategies. She also has developed a research program to characterize the unique aspects of the consent processes in critical care. Additional research interests include acute kidney injury in the intensive care unit, using noninvasive positive pressure ventilation as a weaning strategy, and methodology issues related to study design, implementation, and reporting.

Dr. Burns has been the recipient of several personnel awards including a Canadian Institutes of Health Research Clinician Scientist Award, a Ministry of Research and Innovation Award and a University of Toronto Merritt Committee Award.

Dr. Burns is an Executive Member of the Canadian Critical Care Trials Group and is the Scientific Chair of the Canadian Critical Care Society.
