Epidemiology of traumatic brain injury.

Traumatic brain injury (TBI) is a leading cause of death, and in a recent analysis it was found that nearly one-third of all injury-related deaths in the US have at least one diagnosis of TBI (CDC-Quickstats, 2010). This chapter presents the burden of TBI as regards age group, gender, costs, race, emergency department (ED) visits, hospitalizations, and deaths. Injury trends over a 15 year period are examined. Rehabilitation estimates and disability estimates are also available. Through good epidemiology we can better understand the causes of TBI and design more effective intervention programs to reduce injury. Important sources of evidence for this chapter include mostly studies from the US because of their leading work in the epidemiology of this important injury.
