Primary Objective:
To compare results on the Montreal Cognitive Assessment (MoCA) to those on the Mini-Mental State Examination (MMSE) in patients with traumatic brain injury (TBI) and to predict the outcome at discharge from the acute care setting.
Research Design:
A retrospective study.
Methods And Procedures:
The MoCA and the MMSE were administered to 214 patients with TBI during their acute care hospitalization in a Level I trauma centre. Outcome was measured with the Disability Rating Scale (DRS).
Main Outcomes And Results:
A linear regression determined that the MoCA, the MMSE, TBI severity, education level and presence of diffuse injuries predicted 57% of the total variability of the DRS scores. The model without the MMSE had a R2 of 53.7% and the model without the MoCA had a R2 of 55.0%. The models without the MMSE or the MoCA had a R2 of 24.9%.
Conclusions:
These results indicated that the MoCA and the MMSE function as similar predictors of the DRS at discharge.
