Nutritional Management in Adult Patients With Dysphagia: Position Paper From Japanese Working Group on Integrated Nutrition for Dysphagic People.

This position paper prepared by the Japanese Working Group on Integrated Nutrition for Dysphagic People (JWIND) aims to summarize the need for nutritional management in adult patients with dysphagia, the issues that nutrition professionals should address, and the promising approaches as well as to propose a vision for the future of nutritional care for adult patients with dysphagia. JWIND is a joint certification system recognized by the Japan Dietetic Association and the Japanese Society of Dysphagia Rehabilitation; its members are mostly experts known as "Certified Specialist of Registered Dietitian for Dysphagia Rehabilitation." Malnutrition and dysphagia are associated with each other. Therefore, malnutrition detection and intervention are essential for patients with dysphagia. However, evidence on the usefulness nutritional assessment and intervention to ensure appropriate nutritional care remains insufficient. Here, we present current knowledge of the relationship between primary diseases causing dysphagia and malnutrition, the indicators used for nutritional assessment, and nutritional interventions such as texture-modified diet (TMD) quality improvement, oral nutritional supplementation, and comprehensive intervention. We also discuss the current status and issues in nutritional care for adult patients with dysphagia. Furthermore, we have proposed measures that nutrition professionals should consider based on 3 perspectives: nutritional assessment, TMD, and nutritional intervention. Individualized and specialized nutritional management by registered dietitians (RDs) through appropriate assessment of the nutritional status of adult patients with dysphagia is needed. To maintain and improve swallowing function and nutritional status, RDs should intervene from the state of risk or early dysphagia onset, providing individualized care per their expertise as part of a multidisciplinary team. However, systematic clinical practice and research regarding the association of nutrition with dysphagia are currently insufficient. Therefore, further clinical practice and evidence building, including the verification of the efficacy on nutritional support through intervention research, are needed.
