Getting to know IDDSI
Lately, there has been a lot of buzz over diets, diet levels and a concern about regulating them more effectively. I can honestly say that I have been in more than my fair share of skilled nursing facilities and hospitals over the years and one thing that I have found is that there is a need to have a more standardized dietary program. Some facilities have 4 diets, others 3 and even others have so many additions and substitutions that it is enough to make your head swim.
IDDSI- the International Dysphagia Diet Standardization Initiative (IDDSI) will officially launch May 1, 2019 in the United States after years of development and endorsement by The Academy of Nutrition and Dietetics (AND) and the American Speech-Language-Hearing Association.
According to the IDDSI websitethe premise is to: “Achieve global diet terminology, creating commonterminology and common understanding across international borders, across thelifespan, across all professions, and across all stakeholders to help the careof people with difficulty swallowing (dysphagia).”
The idea is to eliminate confusion between diets that are listed as ground vs chopped and puree vs blender-ized. We have written (at what may feel like length) that Dysphagia is a significant issue that we try to address in skilled nursing. Dysphagia can lead to aspiration pneumonia which may lead to death and or costly hospitalization.
The IDDSI dysphagia diet framework consists of eight levels (0-7) and includes both foods and liquids on a single continuum. Seen below, it takes has an interesting visual model with two triangles one inverted to the other. The levels are identified by numbers, text labels, and color codes with drinks being measured from Levels 0-4, while foods are measured from Levels 3-7.
The IDDSI Model
The IDDSI model expand and separate out the liquids to offer more choices to increase freedom to patients when appropriate. Instead of Thin, Nectar, Honey and Pudding, the nectar is separated into two categories with slightly thick liquids including items such as drinkable supplements. Additionally, levels 3 and 4 include food and drink criteria with level 3 including moderately thick liquids and liquidized foods, and level 4 including extremely thick liquids and pureed foods. If I may editorialize, this is a good thing as we have often run into “soupy” or thin puree that have been problematic in the past.
By Level 5 we are firmly into the area of foods and we see a minced consistency (4mm), which are “swallow-ready” so this diet requires minimal chewing. Level 6 contains bite sizes that are 1.5cm or 15mm, so that if we see premature spillage of the bolus the person is less likely to choke. However, patients can still be at risk depending on how they take their foods.
