OBJECT: Disparities in access to inpatient rehabilitation services after traumatic brain injury (TBI) have been identified, but less well described is the likelihood of discharge to a higher level of rehabilitation for Hispanic or black patients compared with non-Hispanic white patients. The authors investigate racial disparities in discharge destination (inpatient rehabilitation vs skilled nursing facility vs home health vs home) following TBI by using a nationwide database and methods to address racial differences in prehospital characteristics.
METHODS: Analysis of discharge destination for adults with moderate to severe TBI was performed using National Trauma Data Bank data for the years 2007-2010. The authors performed propensity score weighting followed by ordered logistic regression in their analytical sample and in a subgroup analysis of older adults with Medicare. Likelihood of discharge to a higher level of rehabilitation based on race/ethnicity accounting for prehospital and in-hospital variables was determined.
RESULTS: The authors identified 299,205 TBI incidents: 232,392 non-Hispanic white, 29,611 Hispanic, and 37,202 black. Propensity weighting resulted in covariate balance among racial groups. Hispanic (adjusted OR 0.71, 95% CI 0.68-0.75) and black (adjusted OR 0.94, 95% CI 0.91-0.97) populations were less likely to be discharged to a higher level of rehabilitation than were non-Hispanic whites. The subgroup analysis indicated that Hispanic (adjusted OR 0.79, 95% CI 0.71-0.86) and black (OR 0.87, 95% CI 0.81-0.94) populations were still less likely to receive a higher level of rehabilitation, despite uniform insurance coverage (Medicare).
CONCLUSIONS: Adult Hispanic and black patients with TBI are significantly less likely to receive intensive rehabilitation than their non-Hispanic white counterparts; notably, this difference persists in the Medicare population (age ≥ 65 years), indicating that uniform insurance coverage alone does not account for the disparity. Given that insurance coverage and a wide range of prehospital characteristics do not eliminate racial disparities in discharge destination, it is crucial that additional unmeasured patient, physician, and institutional factors be explored to eliminate them.
