Dr. Le Sage is an emergency physician and clinical researcher at the Centre Hospitalier Universitaire de Québec. She is also an associate professor and EM Research Director at the Département de médecine familiale et médecine d’urgence at the Laval University School of Medicine. Her research work focusses on emergency and trauma medicine.

Her main interest is concussions (mild Traumatic Brain Injuries) and the prognosis factors that could predict long-term persistent symptoms after such trauma. Her research program – PoCS Research Program – aims to develop clinical decision rules for clinicians who treat these patients, including the possibility of using biomarkers. The latest Canadian multicentre project in its program aims to validate one of its rules for the early detection of persistent symptoms.

Her research also intends to guide emergency physicians regarding the transfer of major trauma patients within the trauma system. Hence her province-wide Delphi survey to develop a consensus on this issue. The validation of these transfer indicators is ongoing.

Dr. Le Sage has been practicing as an emergency physician for more than 30 years and holds a Ph.D. in epidemiology. Her dual expertise allows her to perform serious work on these issues, and to properly disseminate the resulting information to clinicians.

In addition, she has been a member of the Program Committee of Emergency Medicine for over 15 years, and continues to be involved in the development of research in the Département de médecine familiale et médecine d’urgence at the Laval University School of Medicine, particularly for the development of a research program in emergency medicine. She has also been a member of the Clinician Scientist Program of the Royal College of Physicians and Surgeons of Canada at Laval University.
