  • To learn the causes of death after traumatic brain injury.

Abstract:

Three studies were completed to investigate life expectancy after traumatic brain injury (TBI). Study #1 included 1678 individuals with TBI admitted to one rehabilitation facility between 1961 and 2002. Participants were 1.5 times more likely to die compared to the general population, with a life expectancy reduction of 4 years. Risk factors for death were older age, being male, less education, longer hospitalization, earlier year of injury, and being vegetative at rehabilitation discharge. Participants were at greatest risk of death due to aspiration pneumonia and seizures. Study #2 included 18998 Colorado residents with TBI discharged from acute hospitalization between 1998 and 2003. Participants were 2.5 times more likely to die compared to the general population, with a life expectancy reduction of 6 years. Risk factors for death for those under age 20 were injury severity and older age; and involved multiple domains of demographics (e.g., metropolitan residence), injury-related measures (e.g., falls versus vehicular incidents), and more comorbidities for those older than 20. Participants were at greatest risk of death due to mental/behavioral and neurologic conditions. Study #3 included 2178 individuals with TBI admitted to a TBI Model Systems Center between 1988 and 2000. Participants were twice as likely to die compared to the general population, with an average life expectancy reduction of 7 years. Risk factors for death were older age, no employment, and greater disability. Particpants were at greatist risk of death due to seizures and septicemia compared to the general population. This symposium will include results from a new analysis of 8600 individuals treated in the TBI Model Systems between 1988 and 2008. The symposium will also offer treatment and surveillance implications for TBI follow-up suggested by these life expectancy studies.
