Examining how time from sport-related concussion to initial assessment predicts return-to-play clearance.

Objective: (i) To analyze data of adolescents who have sustained a sport-related concussion (SRC) through the use of Complete Concussion Management Inc. (CCMI) concussion database system; and (ii) to determine an optimal time to assess and manage an athlete with an SRC by prospectively analyzing data from CCMI concussion database system.

Method: A cohort of patients, ages 8-18 years, who sustained an SRC, assessed 30 days or less from injury and were treated at partnered CCMI clinics across Canada were prospectively followed.
