The incidence of sports-and recreation-related concussions (SRRCs) in the United States is unknown. More than 44 million youth participate in sports annually, thus understanding the frequency of SRRCs in children is important on a population level. Our objective was to determine the number of SRRCs occurring annually among US youth ≤18 years old.
METHODS:We identified SRRCs using 3 national databases: MarketScan, National Electronic Injury Surveillance System, and National High School Sports Related Injury Surveillance System, Reporting Injury Online. We determined the number of SRRCs seen in health care settings (outpatient, inpatient, and emergency department) and SRRCs reported to certified high school athletic trainers (ATCs). We used these data and findings in recently published literature to generate a national estimate of SRRCs.
RESULTS:We estimate that between 1.1 and 1.9 million SRRCs occur annually in US children aged ≤18 years. Most children with SRRCs, 511 590 to 1 240 972, were not seen in health care settings. Of children with SRRCs seen in health care settings, most were seen as outpatients with 377 978 visits, compared with between 115 479 and 166 929 ED visits, and between 2886 and 4936 hospitalizations.
CONCLUSIONS:This study provides the most accurate and precise estimate to date of the number of concussions among US children annually. SRRCs are a common injury in children. Providers in all health care settings need to be trained in concussion care. There is a need for better surveillance to enhance our understanding of the epidemiology of concussions in youth. Dr Bryan conducted the data gathering and analysis with Dr Rowhani-Rahbar and led the manuscript writing; Dr. Rowhani-Rahbar conducted the data gathering and analysis with Dr Bryan and contributed to the manuscript preparation and intellectual content; Dr Comstock provided data and feedback on manuscript preparation; Dr Rivara conceived of the study and supervised throughout data gathering, analysis, and manuscript preparation; and all authors approved the fi nal manuscript as submitted. WHAT'S KNOWN ON THIS SUBJECT: Sports-and recreation-related concussions (SRRCs) are a common source of morbidity in children. Many of these injuries are not treated within health care settings. It is unknown how many SRRCs occur annually in the US.

WHAT THIS STUDY ADDS:We estimate between 1.1 and 1.9 million SRRCs occur annually in US children ≤18 years old. The magnitude of this number emphasizes the need for better national injury surveillance of the incidence of SRRCs.by guest on May 10, 2018 http://pediatrics.aappublications.org/ Downloaded from
BRYAN et alConcussions, a form of traumatic brain injury (TBI), are common in children, with sports and recreation as a leading cause in this age group. 1, 2 The incidence of sports-and recreation-related concussions (SRRCs) in the United States is unknown; however, most epidemiologic studies indicate that a large number of SRRCs occur each year.
