Association of positive screening for dysphagia with nutritional status and long-term mortality in hospitalized elderly patients

Objectives: To assess the prevalence of oropharyngeal dysphagia (OD) using the Eating Assessment Tool (EAT-10) and its association with malnutrition and long-term mortality. Material and methods: A retrospective cohort study of patients admitted to the general internal medicine ward. In the first 48 hours after hospital admission, OD was assessed using the EAT-10, and presence of malnutrition with the Mini Nutritional Assessment-Short Form (MNA-SF). Association of OD to malnutrition and long-term mortality was analyzed. Results: Ninety patients with a mean age of 83 (SD: 11.8) years were enrolled. Of these, 56.7% were at risk of OD according to EAT-10. This group of patients had greater prevalence rates of malnutrition (88.2% vs. 48.7%; P= .001) and mortality (70% vs 35.9%; P= .001). During follow-up for 872.71 (SD: 642.89) days, risk of DO according to EAT-10 was an independent predictor of mortality factor in a multivariate analysis (HR: 2.8; 95% CI: 1.49-5.28; P= .001). Conclusions: The EAT-10 is a useful tool for screening OD. Adequate screening for OD is important because of its associated risks of malnutrition and long-term mortality. (C) 2018 SEEN y SED.
