Abstract:

Study investigates the feasibility of using nonrandomized study designs to examine the effectiveness of rehabilitation for traumatic brain injury (TBI). Outcome was assessed using the Glasgow Outcome Scale (GOS), the Sickness Impact Profile (SIP), the Burden Inventory, and Perceived Quality of Life (PQOL). The results indicated that discharge to inpatient rehabilitation from acute care compared with discharge home was associated with worse outcome on the GOS, SIP, and Burden Inventory and with better outcome on the PQOL. Longer inpatient rehabilitation length of stay was associated with worse outcome on all measures.
