Dr. Frances Chung is a Professor of the Department of Anesthesiology and Pain Medicine at the University of Toronto, University Health Network and the ResMed Chair of Anesthesia, Sleep and Perioperative Medicine at University Health Network. She is the Co-Founder and Past President of the Society of Anesthesia and Sleep Medicine. Her research interests are in several areas: sleep apnea, pain, patient safety, monitoring, perioperative medicine, and ambulatory anesthesia. The multi-disciplinary research team that she leads at Toronto Western Hospital is recognized nationally and internationally for contributing to several key areas of research in obstructive sleep apnea, sleep and pain.

Her works led to development of the Post anesthesia Discharge Score (PADS) for the safe discharge of patients from ambulatory surgical unit to home. This score has been adopted worldwide. She developed the STOP-Bang questionnaire www.stopbang.ca), which is a worldwide screening tool for patients with undiagnosed obstructive sleep apnea. In the Web of Science, she has 327 peer-reviewed publications and had been cited 19088 times with an h-index of 73. She has lectured at many national and international meetings, including over 480 invited lectures. Her research work has been recognized through multiple awards including the Royal College of Physicians and Surgeons of Canada’s McLaughlin-Gallie Visiting Professorship; the Research Recognition Award from the Canadian Anesthesiologist’s Society; Research Award from the Department of Anesthesia, University of Toronto; Fellow Teaching Award, University Health Network, the Distinguished Services Award from the Society For Ambulatory Anesthesia, and Life-time Achievement Award by the Society of Anesthesia and Sleep Medicine. Given her expertise, she has been instrumental in developing 14 Guidelines in obstructive sleep apnea, morbid obesity, postoperative nausea and vomiting, post-anesthesia care and ambulatory anesthesia for the American Society of Anesthesiologists, Society for Ambulatory Anesthesia and Society of Anesthesia and Sleep Medicine.

Research/Teaching

Research Synopsis

My most significant contribution has been in generating evidence to prevent postoperative events in patients with obstructive sleep apnea (OSA). My work systematically addressed the early screening for OSA, diagnostic methods and perioperative management. For knowledge translation, I was the Founding Chair of Society of Anesthesia and Sleep Medicine (http://sasmhq.org/) (2010/11), President Elect 2011-13 and President 2013-15. I have established myself as an expert in the area, (h-index:73) and I hold the ResMed Inaugural Research Chair of Anesthesiology, Sleep Medicine at University of Toronto. My major contributions are:

1. Development of the STOP-Bang questionnaire (www.stopbang.ca); a validated and user-friendly tool to screen for OSA in different populations.

Chung F et al. High STOP-Bang score indicates a high probability of OSA. Br J Anaesth. 2012; 108: 768–775. This publication on STOP-Bang score was chosen as one of the top 25 key papers of major importance and contribution to the field of anesthesia in the history of anesthesia by British Journal of Anaesthesia.

I chaired the International 28 member Task Force of Society of Anesthesia and Sleep Medicine to develop 2016 “Guidelines on Preoperative Screening and Assessment of Patients with OSA”. 1st Author, Anesth Analg 2016;123:452-73.

2. Co-Chair and senior author: International POSA trial group on “Postoperative Vascular Events in Unrecognized OSA (POSA)”. We completed the POSA study to determine the associations between OSA, and major postoperative CV events in 1,218 moderate-to-high cardiac risk patients undergoing major noncardiac surgery. We determine that undiagnosed surgical patients have higher risk of postoperative cardiovascular complications.
