Traumatic brain injuries and computed tomography use in pediatric sports participants

Abstract

BackgroundChildhood sports-related head trauma is common, frequently leading to emergency department (ED) visits. We describe the spectrum of these injuries and trends in computed tomography (CT) use in the Pediatric Emergency Care Applied Research Network. MethodsThis was a secondary analysis of a large prospective cohort of children with head trauma in 25 Pediatric Emergency Care Applied Research Network EDs between 2004 and 2006. We described and compared children 5 to 18 years old by CT rate, traumatic brain injury (TBI) on CT, and clinically important TBI (ciTBI). We used multi-variable logistic regression to compare CT rates, adjusting for clinical severity. Outcomes included frequency of CT, TBIs on CT, and ciTBIs (defined by [a] death, [b] neurosurgery, [c] intubation >24 hours, or [d] hospitalization for ≥2 nights). FindingsA total of 3289 (14%) of 23082 children had sports-related head trauma. Two percent had Glasgow Coma Scale scores less than 14. 53% received ED CTs, 4% had TBIs on CT, and 1% had ciTBIs. Equestrians had increased adjusted odds (1.8; 95% confidence interval [CI], 1.0-3.0]) of CTs; the rate of TBI on CT was 4% (95% CI, 3%-5%). Compared with team sports, snow (adjusted odds ratio, 4.1; 95% CI 1.5-11.4) and nonmotorized wheeled (adjusted odds ratio, 12.8; 95% CI, 5.5-32.4) sports had increased adjusted odds of ciTBIs. ConclusionsChildren with sports-related head trauma commonly undergo CT. Only 4% of those imaged had TBIs on CT. Clinically important TBIs occurred in 1%, with significant variation by sport. There is an opportunity for injury prevention efforts in high-risk sports and opportunities to reduce CT use in general by use of evidence-based prediction rules.What is known about this subject: Pediatric sports-related head injuries are a common and increasingly frequent ED presentation, as is the use of CT in their evaluation. Little is known about TBIs resulting from different types of sports activities in children.What this study adds to existing knowledge: This study broadens the understanding of the epidemiology of Pediatric TBIs resulting from different sports activities through a prospective assessment of frequency and severity of ciTBIs and ED CT use in a large cohort of head-injured children in a network of pediatric EDs.
