Abstract
BACKGROUND: Although the impact of malnutrition in patients with acute stroke has been reported, its significance after rehabilitation is not well understood. The geriatric nutritional risk index (GNRI) is a simple and well-established nutritional screening tool that predicts poor prognosis in elderly patients and in those with a high risk of cardiovascular events. We investigated the associations between GNRI and all-cause mortality, cardiovascular events, and infectious diseases in patients with stroke after rehabilitation. METHODS: This study included 138 patients aged 80 years or below who were discharged between 2010 and 2013 in a single center, and followed up for more than 1 year. Malnutrition was defined as a GNRI of 96 or lower. RESULTS: The mean age was 63.9 ± 11.0 years, the mean GNRI at discharge was 98.8 ± 6.5, and the mean total functional independence measure (FIM) score at discharge was 91.8 ± 25.8. Among the patients, 37 (27%) had malnutrition. During the follow-up period, all-cause mortality, cardiovascular events, and infectious diseases were recorded in 11 (8%), 21 (15%), and 20 (15%) patients, respectively. Kaplan-Meier curves showed a significantly higher incidence of each outcome in patients with a GNRI of 96 or lower. In the Cox proportional analysis, GNRI was an independent determinant of all-cause mortality (hazard ratio [HR], .71; 95% confidence interval [CI], .61-.83), cardiovascular events (HR, .87; 95% CI, .80-.95), and infectious diseases (HR, .80; 95% CI, .74-.87) after adjusting for age, gender, and total FIM score. CONCLUSIONS: Malnutrition has a negative impact on prognosis in patients with stroke even after rehabilitation.
