Poster 44 The Utility of the Modified Mini-Mental State Examination in Inpatient Rehabilitation for Traumatic Brain Injury

Abstract

The Modified Mini-Mental State Examination (3MS) could provide useful information about cognitive status in traumatic brain injury (TBI), yet has not been validated in this population. We studied the association of the 3MS with inpatient rehabilitation functional status compared to the Mini-Mental State Examination (MMSE), and the ability of the 3MS to assist with predicting length of stay (LOS). Patients receiving inpatient rehabilitation for TBI were consecutively approached to participate. Participants were administered the 3MS, MMSE, and Functional Independence Measure (FIM) at admission and discharge. Inpatient rehabilitation facility. Male and female patients receiving inpatient rehabilitation services for TBI. Not applicable. 3MS, MMSE, FIM, LOS. The admission 3MS had stronger correlations with admission FIM total, cognitive, and motor scores (r = .72, .76, .56, respectively; all p < .005) than the MMSE. The discharge 3MS had stronger correlations with discharge FIM total, cognitive, and motor scores (r = .86, .73, .68, respectively; all p < .001) than the MMSE. Prediction of LOS was significantly improved with admission 3MS included as a predictor with admission FIM (R^2 change from .53 to .64). Construct validity of the 3MS in a TBI sample was illustrated through significant correlations with the FIM. The 3MS can provide clinicians with more specific information about patterns of cognitive deficits than the cognitive FIM items, which could inform treatment. The improved accuracy in predicting LOS by combining admission 3MS scores with admission FIM scores can be useful for resource planning.
