Dr. MacKenzie's research focuses on the impact of health services and policies on the short-and long-term consequences of traumatic injury. She has contributed to the development and evaluation of tools for measuring both the severity and outcome of injury, which have been used to evaluate the organization, financing and performance of trauma systems and rehabilitation services . Of particular interest to Dr. MacKenzie is the delineation of factors (both medical and non-medical) that explain variations in functional outcome. Her research has advanced the knowledge of the economic and social impact of injuries and our understanding of how personal and environmental factors influence recovery and return to work.

Dr. MacKenzie's ongoing research include: a national evaluation of the cost and effectiveness of trauma care; the evaluation of amputation versus limb salvage in the military; the development and evaluation of self management programs following trauma and limb loss; and efforts to facilitate the development and exchange of information among trauma and EMS providers. Most recently, Dr. MacKenzie and colleagues have partnered with the American Trauma Society to facilitate on-line social networks among trauma survivors and translate traditional self management programs to a web 2.0 environment.
