Swallowing difficulties commonly co-occur with malnutrition in the elderly. However, there is no consensus on which assessment tools to use, and thus reported prevalence varies. The aim of this study was to survey the prevalence of dysphagia and risk of malnutrition in elderly people in nursing homes, evaluate the possible associations between swallowing function and malnutrition and survey whether there were associations between self-perceived function and the results of a screening of dysphagia. A total of 35 residents (aged 67-100 years old) without serious cognitive impairment in the general wards of two nursing homes in Gothenburg were investigated. Swallowing ability was assessed with the Gugging Swallowing Screen (GUSS) test, self-rated swallowing ability with the 4QT and the Swedish Eating Assessment Tool-10 (S-EAT-10) and risk of malnutrition with the Minimal Eating Observation and Nutrition Form-Version 2 (MEONF-II). Eleven participants (31.4%) exhibited dysphagia according to the GUSS and 10 participants (29.4%) showed moderate or high risk of malnutrition. In total 16 (46%) participants reported abnormal swallowing on 4QT and 14 (40%) participants reported abnormal swallowing on S-EAT-10. However, less than half of these had dysphagia according to the GUSS. No association was found between swallowing ability measured by the GUSS and risk of malnutrition, although a tendency towards a weak association was noted, or self-rated swallowing ability measured by the 4QT and S-EAT-10. The study found that approximately one-third of the tested participants presented with signs of dysphagia as measured with the screening instrument GUSS, even though only a few were known to have any difficulties prior to testing. This highlights that dysphagia is probably more prevalent than patients themselves and caregivers are aware of, thus, screening is of importance, to enable safer nutritional intake.
