OBJECTIVE: To identify sex-specific predictors of inpatient rehabilitation
outcomes among patients with a traumatic brain injury (TBI) from a
DESIGN: Retrospective cohort study.
SETTING: Inpatient rehabilitation.
PARTICIPANTS: Patients in inpatient rehabilitation for a TBI within 1 year of
acute care discharge between 2008/2009 and 2011/2012 (N=1730, 70% men, 30%
MAIN OUTCOME MEASURES: Inpatient rehabilitation length of stay, total FIM score,
and motor and cognitive FIM ratings at discharge.
RESULTS: Sex, as a covariate in multivariable linear regression models, was not a
significant predictor of rehabilitation outcomes. Although many of the predictors
examined were similar across men and women, sex-specific multivariable models
identified some predictors of rehabilitation outcome that are specific for men
and women; mechanism of injury (P<.0001) was a significant predictor of
functional outcome only among women, whereas comorbidities (P<.0001) was a
significant predictor for men only.
CONCLUSIONS: Predictors of outcomes after inpatient rehabilitation differed by
sex, providing evidence for a sex-specific approach in planning and resource
allocation for inpatient rehabilitation services for patients with TBI.
