Mild traumatic brain injury (TBI) can no longer be thought of as a ‘low cost’ or ‘short- term’ problem. Associated costs account for a disproportionate cost burden at the macro level, with projected lifetime costs for 2020 more than $89 million. Recent evidence now consistently reveals that nearly half of people who experience a mild TBI report long-term difficulties one year later. This study will assess the cost effectiveness of interdisciplinary approaches to concussion services for mild TBI aimed at reducing post-concussion symptoms and improving work productivity and quality of life 1-year post injury. The outcomes from this research will inform long-term needs and appropriateness of healthcare services after mild TBI, resource allocation and potentially decrease the longer-term healthcare costs.
