TBI-related Emergency Department (ED) Visits
- In 2014, there were approximately 2.5 million TBI-related ED visits in the U.S., including over 812,000 among children.
- Unintentional falls, being unintentionally struck by or against an object, and motor vehicle crashes were the most common mechanisms of injury contributing to a TBI diagnosis in the ED. These three principal mechanisms of injury accounted for 47.9%, 17.1%, and 13.2%, respectively, of all TBI-related ED visits.
- Rates of TBI-related ED visits per 100,000 population were highest among older adults aged ≥ 75 years (1,682.0), young children aged 0-4 years (1,618.6), and individuals 15-24 years (1,010.1).
Trends in Age-adjusted Rates of TBI-related Emergency Department Visits
- Age-adjusted rates of TBI-related ED visits increased 54% from 521.6 per 100,000 population in 2006 to 801.9 in 2014. An increase in age-adjusted rates occurred among nearly all of the major unintentional and intentional principal mechanism categories, including:
- a 24% increase for TBI-related ED visits as a result of motor vehicle crashes (from 85.3 to 106);
- an 80% increase for TBI-related ED visits as a result of falls (from 208.8 to 374.9);
- a 58% increase for TBI-related ED visits as a result of being struck by or against an object (from 90.8 to 143.9);
- a 60% increase for TBI-related ED visits ED visits as a result of intentional self-harm (from 0.5 to 0.8); and
- an 18% increase for TBIs as a result of assault (from 57.6 to 67.8).
