Predictors of quality of life at 6 months in patients with mild stroke: A prospective observational cohort study

Objectives: This study aimed to analyze the factors affecting the long-term quality of life of patients with mild stroke and evaluate the differences according to age and sex. Materials and methods: The Korean Stroke Cohort for functioning and rehabilitation data was used, and patients with mild stroke with a National Institute of Health Stroke Scale score of < 5 were included. Quality of life after 6 months was analyzed using EuroQol-5 dimensions. Demographic and clinical characteristics were evaluated, and factors affecting the quality of life at 6 months were analyzed. Results: Age, current drinking, marital status, length of stay, and modified Rankin Scale, Fugl–Meyer assessment, Functional Independence Measure, and Geriatric Depression Scale scores affected the quality of life at 6 months in patients with mild stroke. Fugl–Meyer assessment score was a predictor for those aged < 65 years, while the functional ambulatory category was a predictor for those aged ≥ 65 years. Predictors of quality of life, excluding alcohol consumption, were comparable between male and female. Conclusions: Among patients aged <65 years, individuals who consumed alcohol, and those who showed better motor function and fewer comorbidities had a higher quality of life. Among patients aged ≥65 years, quality of life was higher in males, younger age, married individuals, those with diabetes, and those with a better walking ability. Among male, individuals who consumed alcohol had a higher quality of life. Rehabilitation treatment should prioritize improving modifiable factors to enhance the quality of life in patients with mild stroke.
