Multidisciplinary Assessment and Individualized Nutritional Management of Dysphagia in Older Outpatients.

introductionThe evidence on the efficacy of nutrition therapy to prevent complications of dysphagia is based on observational studies that used different tools for nutritional and dysphagia assessment, and different scales for the definition of diet textures, rendering their results incomparable and the knowledge on dysphagia management inconclusive.

methodsThis retrospective observational study was performed in 267 older outpatients who were assessed for dysphagia and nutritional status by a multidisciplinary team at the Clinical Nutrition Unit of IRCCS INRCA geriatric research hospital (Ancona, Italy) from 2018 to 2021. GUSS test and ASHA-NOMS measurement systems were used for dysphagia assessment, GLIM criteria for the assessment of nutritional status, and the IDDSI framework to describe the texture-modified diets. Descriptive statistics were used to summarize the characteristics of the subjects evaluated. Sociodemographic, functional and clinical parameters were compared between patients with and without BMI improvement overtime by an unpaired Student's

resultsDysphagia was diagnosed in more than 96.0% of subjects; 22.1% (n = 59) of dysphagic subjects were also malnourished. Dysphagia was treated exclusively by nutrition therapy, prevalently by individualized texture-modified diets (77.4%). For the classification of diet texture, the IDDSI framework was used. The follow-up visit was attended by 63.7% (n = 102) of subjects. Aspiration pneumonia was registered only in one patient (less than 1%), and BMI improved in 13 of 19 malnourished subjects (68.4%). The improvement of nutritional status was primarily reached in subjects whose energy intake was increased and texture of solids modified, in younger subjects, and in those taking less drugs and not reporting any weight loss before the first assessment.

conclusionsThe nutritional management of dysphagia must guarantee both an adequate consistency and energy-protein intake. Evaluations and outcomes should be described with universal scales, in order to allow for comparison between studies and contribute to the collection of a critical mass of evidence on the efficacy of texture-modified diets in the management of dysphagia and its complications.
