OBJECTIVE: The goal of this study was to identify factors that would predict
short-term neuropsychological outcome in patients with traumatic brain injury
(TBI) hospitalized in an acute rehabilitation setting.
METHODS: Data was collected in the context of an acute early rehabilitation
setting of a trauma centre. A brief neuropsychological assessment was carried out
for 348 patients within a month following their trauma.
RESULTS: Length of post-traumatic amnesia (PTA) was the best predictor of
behavioural, memory and executive function variables within a month post TBI. The
odds of being agitated, labile, irritable and disinhibited at one month post
trauma were almost six times higher for those with PTA that lasted more than 7
days compared to those with a PTA of less than 24 hours. Also, the odds of having
a higher mental manipulation score (less significant executive function
impairment) were almost two times lower for those with frontal lesions, and three
to six times lower for those with PTA of more than 24 hours. In addition, TBI
severity, education and age were considered good predictors of some aspects of
neuropsychological outcome.
CONCLUSION: This model may help clinicians and administrators recognize the
probable post-traumatic deficits as quickly as possible and to plan interventions
as well as post-acute discharge orientation accordingly and early on.
