International Dysphagia Diet Standardisation Initiative

The International Dysphagia Diet Standardisation Initiative (IDDSI) is a framework to standardise terminology and offer simple testing methods to check that the preparation of the diets is correct. It promotes safety through standardised terminology. 

The NZSTA and Dietitian NZ endorsed IDDSI in 2017 and have been working with industry, policy, and healthcare providers to achieve successful adoption by the end of 2018. The Health Quality and Safety Commission of New Zealand endorsed IDDSI in 2018.

All details of the diet terminology standards, including a wide range of resources, are available on the IDDSI website, the IDDSI app and IDDSI Youtube Channel
