Association between the Cognitive-Related Behavioral Assessment Severity Stage and Activities of Daily Living Required for Discharge to Home in Patients with Stroke: A Cross-Sectional Study

This study aimed to characterize cognitive function examined using Cognitive-related Behavioral Assessment (CBA) in activities of daily living (ADLs). According to CBA severity at discharge, 791 patients were assigned to five groups (most severe, severe, moderate, mild, and normal). The total scores for Functional Independence Measure (FIM) motor items were compared for each group. Multiple logistic regression analysis was performed to clarify the association between CBA severity and independence in ADL items. Independence in each ADL according to CBA severity was 0–4.8%, 26.8–45.0%, 84.3–91.0%, and 97.2–100% for all ADLs in the most severe to severe, moderate, mild, and normal groups, respectively. Significant differences were found in the FIM motor score according to CBA severity between the groups (p < 0.01). A mild or normal CBA was associated with a higher odds ratio (OR) for dressing the upper body (OR = 21.90; 95% confidence interval (CI), 13.50–35.70), bladder management (OR = 11.60; 95% CI, 7.21–18.60), transfers to the bed/chair/wheelchair (OR = 18.30; 95% CI, 11.40–29.40), transfers to the toilet (OR = 18.30; 95% CI, 11.40–29.30), and walking (OR = 6.60; 95% CI, 10.60–26.10). A CBA severity greater than mild (23 points) was associated with independence in ADLs that are important for discharge to home.
