Risk of Malnutrition Is an Independent Predictor of Mortality, Length of Hospital Stay, and Hospitalization Costs in Stroke Patients

Background Malnutrition is associated with poor outcomes after stroke. Nutrition screening tools (NSTs) are used to identify patients at risk of malnutrition, but so far no NST has been validated for use with patients who have had a stroke. This study aimed to determine the ability of the Malnutrition Universal Screening Tool (MUST) to predict poor outcomes in stroke patients, including mortality, cumulative length of hospital stay (LOS), and hospitalization costs. Methods Patients were recruited from consecutive admissions at 2 hyperacute stroke units in London and were screened for risk of malnutrition (low, medium, and high) according to MUST. Six-month outcomes were obtained for each patient through a national database. Results Of 543 recruited patients, 51% were males, the mean age was 75 years, and 87% had an ischemic stroke. Results showed a highly significant increase in mortality with increasing risk of malnutrition ( P
