Background and aims: The extent of malnutrition in hospitalised stroke patients and its influence on outcomes including hospital complications, length of stay and discharge destination are important issues. The aim of this study was to determine the nutritional status of patients admitted to an acute stoke unit and the association between nutritional status and health outcomes. Methods: Nutritional status was determined prospectively using the scored patient generated subjective global assessment (PG-SGA) in patients (n=73) admitted to an acute stroke unit within 48 hours of admission to an Australian private hospital. Outcome date were collected by retrospective audit. Results: On admission, 19.2% of patients were malnourished and this was associated with a significantly greater PG-SGA score (15 vs 5; p= <0.001) and lower body weight (59.8kg vs 75.8kg; p= 0.004) compared to well nourished patients. In terms of health outcomes, malnourished patients had longer length of stay (13 vs 8 days; p= <0.001), increased complications (50% vs 14%; p= 0.003), increased frequency of dysphagia (71% vs 32%; p= 0.007) and enteral feeding (93% vs 59%; p= 0.017). No association was found between nutritional status and serum albumin level or discharge destination. Conclusions: Malnutrition on admission to hospital after acute stroke is associated with poor outcomes including increased length of stay and increased prevalence of dysphagia and complications. The scored PG-SGA is a nutrition assessment tool that allows quick identification of malnourished stroke patients.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
