Percent Distributions of TBI-related Emergency Department Visits by Age Group and Injury Mechanism — United States, 2006–2010
The injury mechanisms (external causes of injury) associated with TBI-related ED visits vary by age group. Falls are the primary mechanisms of TBI-related ED visits in the youngest (0–4 years) and oldest (65 years and older) age groups, accounting for 72.8% and 81.8% of TBI-related ED visits, respectively. Injuries caused by being struck by/against an object (34.9%) and falls (35.1%) account for the majority of injury in youth 5–14 years of age with respect to TBI-related ED visits. For persons in age groups 15–24 years and 25–44 years, the proportions of TBI-related ED visits due to assaults, falls, and motor vehicle traffic events are nearly equal within and across both age groups.
