Prevalence of signs of dysphagia and associated risk factors in geriatric patients admitted to an acute medical unit

BACKGROUND AND AIMS: Dysphagia is a prevalent disorder among the older persons. Despite this, signs of dysphagia often go unnoticed in hospital settings. This cross-sectional study aimed at investigating the prevalence of signs of dysphagia among patients aged 65 or older in a Danish acute care setting.

METHODS: We studied 334 patients aged 65 years or older admitted to the acute medical unit (AMU) at Aalborg University Hospital, Denmark. Signs of dysphagia were assessed using bedside screening tools including the Eating Assessment Tool (EAT-10), a 30 mL Water Swallowing Test (WST) and the Gugging Swallowing Screen tool (GUSS). Other risk factors were assessed using the Eastern Cooperative Oncology Group Performance Status (ECOG-PS), the Nutritional Risk Screening 2002 (NRS), and the Charlson's Comorbidity Index (CCI).

RESULTS: Signs of dysphagia were identified in 144 of 334 (43.1%) patients. Geriatric patients with signs of dysphagia were significantly older (79.5 years [74; 85] vs. 77 years [72; 84], p = 0.025) and had higher CCI scores (3 points [2; 4] vs. 2 points [1; 4], p = 0.001) than those with normal swallowing capacity. Furthermore, a multivariate logistic regression model found signs of dysphagia to be independently associated with nutritional risk (OR = 2.169, 95% CI 1.313-3.582, p = 0.002), cerebrovascular disease (OR = 2.209, 95% CI 1.235-3.953, p = 0.008), chronic pulmonary disease (OR = 2.276, 95% CI 1.338-3.871, p = 0.002) and rheumatic disease (OR = 2.268, 95% CI 1.099-4.683, p = 0.027). Age was not independently associated with signs of dysphagia among the geriatric patients.

CONCLUSION: Signs of dysphagia were common among patients aged 65 or older in the acute care setting. Signs of dysphagia were associated with nutritional risk, higher CCI scores and specific comorbidities. These findings could indicate a need for systematic screening for dysphagia in acute geriatric patients, yet further investigation is needed to assess clinical outcomes associated with dysphagia within this population.
