Abstract
ObjectivesThe risk of aspiration pneumonia has been reported to increase with age, especially in elderly residents of nursing homes. However, the characteristics of those with swallowing impairments at elderly care facilities have not yet been evaluated using reliable instrumental examinations. The aims of the current study were to investigate the frequency of swallowing impairment and determine the characteristics of the elderly with swallowing disorders residing at care facilities. MethodsTo reveal the characteristics of the elderly with swallowing disorders, questionnaires for dysphagia screening and flexible endoscopic evaluation of swallowing (FEES) were used. Regarding the dysphagia screening, two types of questionnaires were sent to 451 elderly persons aged 65 years and older who were living in facilities for the elderly in Japan. FEES was performed to assess swallowing impairment at each facility for those who were found to be positive for dysphagia by the questionnaires. The frequency of swallowing impairment and the characteristics of elderly subjects with swallowing disorders were investigated. ResultsAmong 413 subjects who completed both questionnaires, 229 were screened positive for dysphagia, 160 of whom underwent FEES. Swallowing impairment was observed in 93 subjects. The subjects with swallowing impairment had a significantly high prevalence of fever, sputum, and/or history of aspiration pneumonia. Their oral intake ability and activities of daily living were significantly low. ConclusionWe demonstrated the frequency of swallowing disorders and the characteristics of elderly subjects with swallowing disorders living in care facilities using FEES. Our results suggest the importance of screening all elderly care facility residents for dysphagia.
