What is the IDDSI Framework

Three years of ongoing work by the International Dysphagia Diet Standardisation Committee came to fruition in November 2015 with the final IDDSI framework.

Our plan is for the framework to be translated into a number of languages as part of worldwide implementation.  A review of existing standards, available evidence and collaborative efforts from stakeholder groups has resulted in a framework that is culturally sensitive, measureable and applicable to individuals of all age groups in all care settings.

The framework documents have recently been re-organised and updated. In addition to adding new information, the re-organisation makes it easier to find framework information to use and share, as the documents are shorter and divided into 4 specific topic areas (The Complete IDDSI Framework; IDDSI Testing Methods; IDDSI Evidence and IDDSI FAQs). Click on the Framework below.

Complete IDDSI Framework & Descriptors

The final dysphagia diet framework consists of a continuum of 8 levels (0-7), where drinks are measured from Levels 0 – 4, while foods are measured from Levels 3 – 7. Read more about the descriptors, testing methods, and the evidence from research.  (Updated: October 2016)  We are also thrilled to announce translations are underway and can be found here.
