The 5th International Consensus Statement on Concussion in Sport introduced several new recommendations that have direct and practical implications for the clinician. One of the new characteristics of the work of the Concussion in Sport Group is the methodology used and the 18 months of work that preceded the consensus conference itself. Twelve key questions were defined using a Delphi technique, and each of these questions led to a systematic review of the available evidence regarding each topic. As part of that methodology, a 2-day conference occurred and was followed by a 1-day consensus meeting with an extended group of multidisciplinary experts to summarize the evidence and discussion at the conference and achieve a consensus on proposed recommendations from each of these reviews. The output of this conference is summarized in the 5th International Consensus Statement on Concussion in Sport.
