All adults with concussion who had 2 years of follow-up health care information were included, representing 587 057 adults in total, and the team looked at premorbid health conditions like migraine, mental health and psychiatric conditions, neurological disorders, vestibular disorders, chronic pain, prior concussion, as well as demographic data and how often someone accessed their family medicine and/or walk-in clinic in the year before their injury. Using administrative health databases, the team then tracked how many saw a specialist physician like a neurologist, ENT, psychiatrist, ophthalmologist, physical medicine & rehab physician, or a neurosurgeon for concussion related treatment after in the 2 years after injury. Anyone that required 2 or more specialist visits for concussion related complaints more than 6 months after their injury were classified as having persisting post-concussion symptoms and the factors that increased the risk of requiring additional health care for concussion were determined. This calculator provides the absolute risk that an individual may have of requiring additional specialized health care for persisting post-concussion symptoms based upon the 5 factors identified.
