Prediction of functional outcome and discharge destination in patients with traumatic brain injury after post-acute rehabilitation

Abstract

As the survival rate of traumatic brain injury increases, the burden of care for patients with traumatic brain injury is emerging as a socioeconomic issue and the discharge destination is one of the important outcome measures in the post-acute rehabilitation unit. To investigate the predictors of functional outcome and discharge destination in patients with traumatic brain injury after post-acute rehabilitation. A retrospective review was performed on 86 patients who were admitted to the rehabilitation unit between January 2010 and June 2017. Multiple regression analysis was used as a statistical method to identify the factors affecting Modified Barthel Index and discharge destination. The number of days from traumatic brain injury onset to rehabilitation unit admission (odds ratio = 0.959, P = 0.049), brain surgery for traumatic brain injury management (odds ratio = 0.160, P = 0.021), initial Glasgow Coma Scale score (odds ratio = 1.269, P = 0.022) and Mini-Mental State Examination score at admission (odds ratio = 1.245, P < 0.001) were the predictive factors for higher Modified Barthel Index after rehabilitation. Underlying vascular risk factors (odds ratio = 0.138, P = 0.015), Modified Barthel Index score after rehabilitation (odds ratio = 1.085, P < 0.001) and deductible-free insurance (odds ratio = 0.211, P = 0.032) were the predictive factors of home discharge. The functional outcome of patients with traumatic brain injury after rehabilitation was related to the severity of initial injury, cognitive function at admission and rehabilitation timing. The discharge destination after rehabilitation was related to functional outcome, insurance issues and underlying vascular risk factors.
