Abstract:

Study computed the life expectancy of individuals with traumatic brain injury (TBI) based on validated prognostic models, compared mortality and life expectancy of people with TBI with those of the general population, and investigated trends toward improved survival over the last 2 decades. Life expectancy data were obtained from 2 cohorts of long-term survivors of TBI: (1) the Traumatic Brain Injury Model Systems (TBIMS) cohort comprised 7,365 persons who were admitted to a TBIMS facility with moderate-to-severe TBI and assessed at 1 year after injury, and (2) the California Department of Developmental Services (CDDS) cohort comprised 5,116 persons who sustained a TBI and received long-term services from the CDDS. Analysis indicated that the estimates of age-, sex-, and disability-specific life expectancy of people with TBI derived from the CDDS and TBIMS were similar. The estimates of age- and sex-specific life expectancy were lower than those of the general population. Mortality rates of people with TBI were higher than those of the general population. Mortality rates did not improve and the standardized mortality ratio increased over the study period from 1988 to 2010. The findings suggest that life expectancy of individuals with TBI is lower than that of the general population and depends on age, sex, and severity of disability. When compared, the survival outcomes in the TBIMS and CDDS cohorts are remarkably similar. Because there have been no marked trends in the last 20 years, the life expectancies presented in this article may remain valid in the future.
