Abstract
Dysphagia is a symptom that appears with high prevalence in persons diagnosed with dementia, intellectual disability, or severe mental illness. Risk of aspiration pneumonia or even death is very high in these populations. However, screening for dysphagia risk in these patients is complicated by the fact that most of them suffer from cognitive impairments and behavioral manifestations that hinder the assessment process using the existing screening tests. The aim of this study was to validate the Oropharyngeal Dysphagia Screening Test for Patients and Professionals, in patients with cognitive impairment (dementia/intellectual disability) or with severe mental illness (schizophrenia and other psychotic disorders, bipolar disorder, or major depressive disorder). For this purpose, 148 institutionalized patients were evaluated by professionals responsible for their food intake. The Oropharyngeal Dysphagia Screening Test for Patients and Professionals was used to assess its validity in screening for oropharyngeal dysphagia in patients with cognitive impairments and in patients with severe mental illness. Also, the Eating Assessment Tool-10 and the Swallowing Disturbance Questionnaire were used for convergent reliability procedures. Four comparison groups were established: patients with cognitive impairment with and without oropharyngeal dysphagia, and patients with severe mental illness with and without oropharyngeal dysphagia. Results from the Oropharyngeal Dysphagia Screening Test for Patients and Professionals adequately distinguished between groups with and without dysphagia, in addition to presenting adequate levels of convergent validity and reliability. These results were obtained from other-reports (professionals responsible for patients' food intake), using a simple, quickly applied test that does not require the use of food in patients with an altered cognitive state or with severe mental illness. With this study we expand the validity of the Oropharyngeal Dysphagia Screening Test for Patients and Professionals in populations with severe cognitive deficits and mental illness in which there is a great deficiency of oropharyngeal dysphagia screening instruments.
