International Dysphagia Diet Standardisation Initiative

Also written as: IDDSI — International Dysphagia Diet Standardisation Initiative

Global framework providing standardized terminology and definitions for texture-modified foods and thickened liquids in dysphagia management.

Full Definition

The International Dysphagia Diet Standardisation Initiative (IDDSI) is a comprehensive framework developed to standardize dysphagia diet terminology worldwide. IDDSI provides eight levels (0-7) describing liquid consistency and food texture modifications, with specific testing methods to verify appropriate consistency. This standardization improves communication between healthcare providers, reduces confusion in diet recommendations, and enhances patient safety across different healthcare settings and geographic regions. The framework includes detailed descriptors, measurement tools, and testing protocols for each level.
