Biographical Sketch

Dr. Shawn Marshall is a physician specializing in Physical Medicine and Rehabilitation (Physiatrist). He is the Medical Director for Acquired Brain Injury Rehabilitation at the Ottawa Hospital Rehabilitation Centre where he manages both in-patients and out-patient clinics. Dr. Marshall has a Master's degree in Clinical Epidemiology and is an Associate Professor at the University of Ottawa in the Department of Medicine.

Driving and disability, specifically older driver research, is one of the main areas of clinical research interest for Dr. Marshall. His driving research interests have focused on conditional licensing as well as assessing medical fitness to drive. Dr. Marshall was a founding principle co-investigator's for the "Canadian Driving Research Initiative for Vehicular Safety in the Elderly" (Candrive) which was funded from 2002-2007 by CIHR as a New Emerging Team. The Candrive research team worked to develop a national network of researchers and partners focusing on older driver research with the aim of improving safety and fair assessment for older drivers. The Candrive research program has since progressed to "The CIHR Team in Driving in Older Persons (Candrive II) Research Program" (2008-2013) where Dr. Marshall is a principle co-investigator. This ground-breaking multi-million dollar project has been funded by CIHR as a Team Grant. It is a national longitudinal study involving 7 sites and over 1000 older drivers that will generate knowledge for use by transportation policy makers, clinicians and the general public to improve the safety and quality-of-life of older drivers in Canada and abroad. The Candrive team has been awarded a continuation grant by the Canadian Institute of Health Research to continue the Candrive study into 2016. The Candrive research agenda will: 1) Increase understanding of the natural history of driving in those over 70 years; 2) Measure the impact of medical and functional conditions on crash rates; 3) Lead to the development of clinical tools that identify older persons who are and are not at risk of future crashes and those who need to undergo further in-depth testing of driving ability; 4) Develop and begin to evaluate the effectiveness of driver retraining and education programs; 5) Clarify the role of on-road and driving simulator testing in the process of older driver assessment; 6) Lessen the difficulties associated with the transition to non-driving; and 7) Assist seniors to identify and use automobile technological innovations to their advantage.

Dr. Marshall's other main focus of research relates to his clinical interest in Acquired Brain Injury Rehabilitation. He has been proactive in the promotion and development of ABI clinical guidelines for several years, working on reviews for the Evidence Based Reviews in Acquired Brain Injury Team ( where he is a co-investigator for the project. This has lead to the development of Practice Guidelines for rehabilitation of moderate and severe acquired brain injury through the Acquired Brain Injury Knowledge Uptake Strategy Group (ABIKUS). Dr. Marshall has led the development of Clinical Guidelines for the Care of Persisting Symptoms after Mild Traumatic Brain Injury which involved national and international experts in mild TBI.

Dr. Marshall has also been part of a multidisciplinary team that has developed and implemented online referral tools and a referral tracking system for both the ABI and TBI rehabilitation populations. The Rehabilitation Transition Tracking System (RITTS) tool has been adopted by the Ottawa Hospital, Bruyère Continuing Care and Queensway Carleton Hospitals and will be implemented in other regional facilities by the end of 2010.
