Cognitive orientation in rehabilitation and neuropsychological outcome after traumatic brain injury

This study evaluated the ability of the Orientation Log (O-Log) to predict cognitive outcome at rehabilitation discharge, as well as future neuropsychological outcome. The hypothesis was that patients who demonstrated better orientation upon admission would achieve superior functional cognitive outcome at discharge and on subsequent neuropsychological assessment. Sixty individuals receiving inpatient rehabilitation following a new-onset TBI participated. Orientation data was collected using the O-Log during morning bedside rounds. Outcome data was collected at 6 and 12 months post-injury. Significant correlations were found between the O-log and measures of memory, executive functioning, basic verbal skills, and estimated intellectual ability. When compared to the other predictor variables, step-wise multiple regression analyses revealed that the minimum O-Log score was the primary significant predictor of performance on six neuropsychological and functional outcome measures. Results of this study suggest that evaluating orientation with the O-Log during acute rehabilitation may reflect level of injury severity and aid in predicting cognitive outcome.
