Objective
To investigate the contribution of the Cogstate Brief Battery (CBB TM) in the explanation of variation of functional outcomes.
Design
Secondary analysis of the practice-based evidence data set.
Setting
Inpatient rehabilitation setting.
Participants
Patients (≥ 18 years of age) with traumatic brain injury who were consecutively admitted to the Toronto Rehabilitation Institute between 2008 and 2011 (n = 65).
Interventions
Not applicable Main outcome measure: Cognitive and motor components of the Functional Independence Measure.
Results
The addition of the CBB TM components resulted in a significantly better model for predicting outcomes than a basic model using demographics and clinical factors. Among all CBB TM components, speed and variation in the identification task and accuracy in the one card learning task were significantly associated with cognitive functional outcomes after controlling for demographic and clinical factors. Rehabilitation length of stay was the only significant clinical factor that was correlated with both cognitive and motor outcomes.
Conclusions
Findings of this study suggest the importance of considering visual attention and visual memory in predication of cognitive outcome and provide valuable information for researchers to consider the specific cognitive abilities in functional outcome model in future studies in addition to more traditional factors.
