  1. 1. Swallowing dysfunction among older people in short-term care : prevalence, effect of intervention, and risk of mortality

    Författare :Patricia Hägglund; Eva Levring Jäghagen; Per Wester; Mary Hägg; Karin Brunnegård; Per Östberg; Umeå universitet; []
    Nyckelord :swallowing disorder; dysphagia; elderly care; intermediate care; undernutrition; oral health; treatment; rehabilitation; quality of life; mortality risk; survival;

    Sammanfattning : Objectives: Swallowing dysfunction (dysphagia) is a common, but often neglected condition among geriatric patients that can cause severe complications such as malnutrition, aspiration pneumonia and death. The aims of this thesis were to (i) describe the study design and method of the multidisciplinary and multicenter project SOFIA (Swallowing function, Oral health, and Food Intake in old Age), (ii) study the prevalence of and the relationship between swallowing dysfunction and risk of undernutrition among older individuals in short-term care, (iii) study the effect of oral neuromuscular training on swallowing dysfunction among older individuals, and (iv) to investigate the association between poor oral health, swallowing dysfunction and mortality.
