Objective: To evaluate predictors of non-return to work (nRTW) among social,
demographic, clinical, and psychiatric variables after severe traumatic brain
injury (TBI) in a cohort of Brazilian patients. Methods: Prospective study.
Forty-three community-dwelling individuals treated at a Level I trauma center at
the time of TBI were evaluated 18 months after trauma. Measures included
DSM-IV-TR criteria for personality changes after TBI and Structured Clinical
Interview for DSM-IV Axis I Disorders (SCID-I) to assess psychiatric diagnosis.
Hospitalization variables included Glasgow Coma Scale scores, pupil examination
findings, associated limb trauma, Marshall computed tomography classification,
and blood glucose levels. Results: After multiple logistic regression analysis,
only the diagnosis of personality changes was found to be independently
associated with nRTW, with an adjusted odds ratio of 10.92 (p = 0.02, 95%
confidence interval 1.41-84.28). Conclusions: In this study, personality changes
were an independent predictor of nRTW after severe TBI. Ways to predict risk
factors associated with personality changes after severe brain injury could aid
in identification of early and effective interventions that might ease the burden
associated with this condition.
