TBI-related Hospitalizations

Key Findings
  • In 2014, there were approximately 288,000 TBI-related hospitalizations in the U.S., including over 23,000 among children.
  • Unintentional falls and motor vehicle crashes were the most common mechanisms of injury contributing to a TBI diagnosis in which the patient was hospitalized. These two principal mechanisms of injury accounted for 52.3% and 20.4%, respectively, of all TBI-related hospitalizations.
  • Rates of TBI-related hospitalizations per 100,000 population were highest among older adults aged ≥75 years (470.6), those aged 65-74 years (145.5), and individuals 55-64 years (89.5).

Trends in age-adjusted rates of TBI-related Hospitalizations

  • From 2006 to 2014, age-adjusted rates of TBI-related hospitalizations decreased by nearly 8% (from 92.2 per 100,000 population to 84.9).
  • This decrease coincides with a 34% decrease in the age-adjusted rate of TBI-related hospitalizations attributable to motor vehicle crashes (27.6 in 2006 to 18.1 in 2014).
  • Despite the overall decrease in TBI-related hospitalization rates, there were increases in the age-adjusted rates of TBI-related hospitalizations attributable to falls (33.9 in 2006 to 42.9 in 2014) and intentional self-harm (0.4 in 2006 to 0.6 in 2014).
