It’s time to give concussion an operational definition: A 3-step process to diagnose (or rule out) concussion within 48 hours of injury: World Rugby Guideline

Abstract

World Rugby has introduced an operational definition of concussion into Rugby to better identify and manage concussion and to support injury surveillance studies. This definition acknowledges the variability in clinical concussion presentation by incorporating a three-point in time diagnostic process with the recommended times aligning with the times that team doctor’s normal responsibilities involve team contact. The current content of each assessment is based on SCAT 3 and will continue to be modified as the evidence around concussion diagnosis evolves. This operational definition of concussion also includes the recommendation that any abnormal assessment be considered as being due to concussion. This default can be overruled if the team doctor decides that the abnormal assessment is not related to a concussion. Finally with World Rugby’s operational definition, a concussion following a head injury cannot be excluded until an assessment is completed at 36-48 hours post injury.
