A scoping review of the evidence for the use of screening tools in people with intellectual disabilities with dysphagia

Background: Dysphagia can have serious health implications including choking and respiratory infection leading to poorer quality of life. People with intellectual disabilities are at higher risk of dysphagia related health complications and early death. Robust dysphagia screening tools are vital for this population. Method: A scoping review and appraisal of the evidence for dysphagia and feeding screening tools for use with people with intellectual disabilities was undertaken. Results: Seven studies (using six screening tools) met the review inclusion criteria. Mostly studies were limited by no defined dysphagia criteria, no verification of tools with a gold reference standard (e.g., videofluoroscopic examination) and lack of participant diversity (small samples, narrow age range, severity of intellectual disability or limited settings). Conclusions: There is urgent need for development and rigorous appraisal of existing dysphagia screening tools to meet the needs of a wider range of people with intellectual disabilities (particularly mild-to-moderate severity) and in wider settings
