Abstract:
OBJECTIVE: To validate the Motor Impairment Scale (MIS) of the Korean long-term care insurance (LTCI) system by comparing with the service time offered for aiding activities of daily living (ADL) and the ADL score. METHODS: A total of 407 elderly subjects without dementia who had used LTCI services were included in this study. Spearman correlations and multivariate linear regression models were employed to determine the relationship of the upper and lower limb MIS (U-MIS and L-MIS, respectively) to the service time and ADL. Stratified analyses for the facility group (n=121) and the domiciliary group (n=286) were performed. RESULTS: There were significant differences in characteristics between facility group and domiciliary group. The MIS was significantly correlated with service time in facility group (Spearman p=0.41 for U-MIS, Spearman p=0.40 for L-MIS). After adjusting for age, sex, and cognition score, U-MIS was an independent predictor for service time in facility group (p=0.04). In domiciliary group, no significant correlation was found between the MIS and service time. The MIS correlated with all of the ADL items and total ADL score in both groups. After adjusting for other factors including age, sex, and cognitive score, U-MIS and L-MIS were independent variables for explaining the total ADL score in both groups. CONCLUSION: The validity of the MIS as an evaluation tool in the physically-disabled elderly is higher in facility group than in domiciliary group. As an easy, objective, and simple method, MIS can be a useful tool in the LTCI system of Korea.
