Objectives: The objective of this study was to characterize emergency department (ED) visits for pediatric sport-related concussion (SRC) in pre-high school- versus high school-aged athletes.
Methods: A stratified probability sample of US hospitals that provide emergency services in the National Electronic Injury Surveillance System (1997-2007) and All Injury Program (2001-2005) was used. Concussion-related ED visits were analyzed for 8- to 13- and 14- to 19-year-old patients.
