NDD vs IDDS: Dysphagia Diet Standardization ecourse

Course overview

Speech-Language Pathologists and Occupational Therapists play a vital role in recommending appropriate diets and liquids after bedside evaluations, MBSs, or FEES assessments. However, clear and consistent communication with nursing and dietary teams is essential for patient safety and successful outcomes. In 2002, the National Dysphagia Diet (NDD) was developed to standardize terminology and identify diet level challenges. While widely used, variability in definitions and terminology across care settings and cultures became a significant barrier to safety. To address these inconsistencies, the International Dysphagia Diet Standardization Initiative (IDDSI) was launched in 2013. IDDSI provides a globally standardized framework for describing texture-modified foods and thickened liquids. As of 2021, it is the only professionally recognized and supported framework across disciplines-including SLPs, OTs, physicians, nurses, and dietary staff. Yet, many facilities continue to rely on outdated NDD guidelines or use inconsistent internal criteria, creating risk for miscommunication and potential litigation. This course emphasizes: The differences between NDD and IDDSI. Why standardization matters. The importance of testing foods and liquids to confirm the correct consistency. How to align your facility's practices with current professional standards to improve safety and outcomes for individuals with dysphagia.
