International Dysphagia Diet Standardisation Initiative (IDDSI)
After a swallow assessment people may be advised to adjust the texture of their food or drinks to make them safer or easier to swallow. The International Dysphagia Diet Standardisation Initiative (IDDSI) is used to describe the texture of foods and thickness of drinks and has been in use in the Northern Health & Social Care Trust since October 2018.
More information can be found on the IDDSI website. There is also a helpful free IDDSI app available to download.
The IDDSI framework consists of 8 levels (0-7), where drinks are measured from Levels 0 – 4, while foods are measured from Levels 3 – 7. The IDDSI Framework provides a common terminology to describe food textures and drink thickness.
