OBJECTIVES: To compute the life expectancy of persons with traumatic brain injury
(TBI) based on validated prognostic models from 2 cohorts, to compare mortality
and life expectancy of persons with TBI with those of the U.S. general
population, and to investigate trends toward improved survival over the last 2
decades. DESIGN: Survival analysis. SETTING: Postdischarge from rehabilitation
units and long-term follow-up at regional centers. PARTICIPANTS: Two cohorts of
long-term survivors of TBI (N=12,481): the Traumatic Brain Injury Model Systems
(TBIMS) cohort comprised 7365 persons who were admitted to a TBIMS facility with
moderate to severe TBI and were assessed at >/=1 years postinjury, and the
California Department of Developmental Services (CDDS) cohort comprised 5116
persons who sustained a TBI and received long-term services from the CDDS.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Life expectancy. RESULTS:
The estimates of age-, sex-, and disability-specific life expectancy of persons
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 U.S. general
population. Mortality rates of persons with TBI were higher than those of the
U.S. general population. Mortality rates did not improve and the standardized
mortality ratio increased over the study period from 1988 to 2010. CONCLUSIONS:
Life expectancy of persons 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.
