Relationship Between Mild Cognitive Impairment and Activities of Daily Living in Older Patients in Convalescent Rehabilitation Wards

Abstract

Aims

Rehabilitation is commonly used in older patients with mild cognitive impairment (MCI). This study aimed to determine whether MCI affects the effectiveness of rehabilitation in older patients.

Methods

This was a retrospective cohort study of patients who received rehabilitation in convalescent rehabilitation wards (CRW) in Japan between January 2021 and December 2022.

Results

141 patients who met inclusion criteria were included in this study. The patients were divided into MCI and non-MCI groups based on the Mini Mental State Examination score. At admission, MCI patients were significantly older, and had longer hospital stays, malnutrition, lower grip strength, and lower motor independence measures (FIMS) scores. After propensity score matching to adjust for differences in baseline characteristics, motor FIMS scores at discharge remained lower in the MCI group.

Conclusions

The presence of MCI is associated with ADL at discharge in older adults admitted to a CRW for rehabilitation.
