Objectives

To examine racial differences in competitive employment outcomes at 1, 2, and 5 years after traumatic brain injury (TBI) and to determine whether changes in not competitive employment rates over time differ between blacks and whites with TBI after adjusting for demographic and injury characteristics.

Design

Retrospective cohort study.

Setting

Sixteen TBI Model System Centers.

Participants

Blacks (n=615) and whites (n=1407) with moderate to severe TBI.

Interventions

Not applicable.

Main Outcome Measure

Employment status dichotomized as competitively employed versus not competitively employed.

Results

After adjusting for demographic and injury characteristics, repeated-measures logistic regression indicated that (1) the odds of not being competitively employed were significantly greater for blacks than whites regardless of the follow-up year (all P<.001); (2) the odds of not being competitively employed declined significantly over time for each race (P≤.004); and (3) changes over time in the odds of not being competitively employed versus being competitively employed were not different between blacks and whites (P=.070). In addition, age, discharge FIM and Disability Rating Scale, length of stay in acute and rehabilitation, preinjury employment, sex, education, marital status, and cause of injury were significant predictors of employment status postinjury.

Conclusions

Short- and long-term employment is not favorable for people with TBI regardless of race; however, blacks fare worse in employment outcomes compared with whites. Rehabilitation professionals should work to improve return to work for all persons with TBI, with special emphasis on addressing specific needs of blacks.
