Research Synopsis

Dr. Wijeysundera’s research program focuses on developing methods to reduce risks of medical complications following major noncardiac surgery and evaluating the impact of variation in perioperative processes-of-care on surgical outcomes. His research has resulted in more than 100 peer-reviewed publications while implementing a range of methodologies such as prospective cohort studies, randomized controlled trials, and health services research. Dr. Wijeysundera holds a Canadian Institutes of Health Research (CIHR) New Investigator Award, while his research program has been supported by the CIHR, Heart and Stroke Foundation of Canada, Ontario Ministry of Research and Innovation and Ontario Academic Health Sciences Centres Innovation Fund. In addition to his research activities, Dr. Wijeysundera is a member of the American College of Cardiology and American Heart Association Task Force on Practice Guidelines, and is co-chair of the Choosing Wisely Canada initiative of the Canadian Anesthesiologists Society.
