BackgroundDespite the increasing rate of survival from hypoxic-ischemic brain injury (HIBI), there is a paucity of evidence on the long-term functional outcomes after inpatient rehabilitation among these nontrauma patients compared to patients with traumatic brain injury (TBI).ObjectivesTo compare functional and psychosocial outcomes of patients with HIBI to those of case-matched patients with TBI 4-11 years after brain insult.DesignRetrospective, matched case-controlled study.MethodsData at the time of rehabilitation admission and discharge were collected as part of a larger acquired brain injury (ABI) database at Toronto Rehabilitation Institute (TRI) between 1999 and 2009. This study consisted of 11 patients with HIBI and 11 patients with TBI that attended the neuro-rehabilitation day program at TRI during a similar time frame and were matched on age, admission Functional Independence Measure (FIM) scores, and acute care length of stay (ALOS). At 4-11 years following brain insult, patients were reassessed using the FIM, Disability Rating Scale (DRS), Personal Health Questionnaire Depression Scale (PHQ-9), and the Mayo-Portland Adaptability Inventory 4 (MPAI-4).ResultsAt follow-up, patients with HIBI had significantly lower FIM motor and cognitive scores than patients with TBI (75.3 ± 20.6 versus 88.1 ± 4.78, P < .05, and 25.5 ± 5.80 versus 32.7 ± 2.54, P <.05, respectively) despite having a similar time frame postinsult (ie, 4-11 years). In addition, there were significant differences in motor and total FIM change from admission to follow-up between HIBI and TBI patients (P < .05). Patients with HIBI also had significantly lower scores on the DRS, PHQ-9, and total MPAI-4 at follow-up (P < .05).ConclusionsThe study results suggest that patients with HIBI achieve less long-term functional improvements compared to patients with TBI. Further research is warranted to compare the components of inpatient rehabilitation while adjusting for demographics and clinical characteristics between these 2 groups of patients.Level Of EvidenceIII.Copyright © 2017 American Academy of Physical Medicine and Rehabilitation.
