Summary of "IDDSI 201 Testing Methods for Healthcare Professionals"

This webinar provides detailed instruction on the International Dysphagia Diet Standardization Initiative (IDDSI) food and liquid testing methods, aimed at healthcare professionals managing patients with dysphagia. It builds on the introductory IDDSI 101 webinar and focuses on practical, objective, and standardized testing methods to classify food and drink textures safely.

Main Ideas and Concepts

IDDSI Overview:
- IDDSI offers a global standardized framework for dysphagia diets, ranging from Level 0 (thin liquids) to Level 7 (regular foods).
- The framework includes detailed descriptors and testing methods to ensure safe swallowing and reduce choking risk.
- Testing methods use simple, commonly available tools (forks, spoons, syringes) and are adaptable globally.
Objectives of the Webinar:
- Familiarize healthcare professionals with all IDDSI testing methods.
- Enable successful testing and classification of foods and liquids in clinical or care settings.
- Understand food behavior and troubleshoot items that do not meet testing criteria.
Testing Methods Covered:
1. Food Size Assessments (Choking Risk Reduction):
  - Level 6 (Soft & Bite-Sized): Food pieces should be ≤1.5 cm x 1.5 cm to reduce choking risk.
  - Use common references like adult thumbnail or fork width to measure size.
2. Particle Size Requirements (Minced & Moist Level 5):
  - Adults: Particles approx. 4 mm x 4 mm x ≤15 mm.
  - Pediatrics: Particles approx. 2 mm x 2 mm x ≤8 mm.
  - Particles should be moist and cohesive, not dry or crumbly.
3. Spoon Tilt Test (Cohesiveness and Moisture):
  - Tests if food (pureed or minced) slides easily off a spoon with minimal residue.
  - Food should be moist, cohesive, but not sticky.
  - Important for Level 4 (Pureed) and Level 5 (Minced & Moist).
4. Fork Pressure Test (Firmness):
  - Apply pressure with a fork until thumbnail blanches (white).
  - Food should squash or break apart easily and not stick to the fork.
  - Level 5 foods require less pressure (thumbnail does not blanch).
  - Levels 6 and 7 require enough pressure to blanch thumbnail.
5. Fork Spoon Separation Test (Softness for Easy Oral Processing):
  - Food should break apart easily with the side of a fork or spoon.
  - Used for Level 6 (Soft & Bite-Sized) and Level 7 (Easy to Chew).
6. Testing Transitional Foods:
  - Foods that change texture when exposed to moisture or temperature (e.g., ice chips, popsicles, teething wafers).
  - Use a modified Fork Pressure Test with added water to simulate saliva.
  - Evaluate if the food dissolves or disintegrates quickly into a safe texture.
7. Liquid Testing:
  - IDDSI Flow Test: Uses a 10 ml syringe or funnel syringe to measure liquid flow over 10 seconds.
    - Amount remaining in syringe after 10 seconds determines liquid thickness level (Levels 0-3).
    - Level 4 (Extremely Thick) cannot be tested with flow test.
  - Fork Drip Test: For Levels 3-5 foods and Levels 3-4 liquids.
    - Food/liquid should hold on fork tines without dripping through.
    - Used to assess cohesiveness and thickness.
Additional Important Points:
- IDDSI testing methods are evidence-based, portable, inexpensive, and adaptable worldwide.
- Testing ensures food/liquid textures match clinician recommendations and patient safety needs.
- Temperature and saliva can affect viscosity and texture.
- Facilities should verify appropriate tools (e.g., correct syringes) and thickeners.
- IDDSI resources include printable frameworks, audit sheets, checklists, and apps for easy use.
Resources and Further Learning:
- IDDSI website (IDDSI.org" target="_blank" rel="noopener noreferrer">www.IDDSI.org) offers updated documents, audit tools, presentations, and videos.
- IDDSI YouTube channel provides additional demonstrations.
- IDDSI app available on iOS and Android for offline access to testing methods and videos.

Detailed Bullet Point Summary of Testing Methods

Food Size Assessment (Level 6 Soft & Bite-Sized):
- Food pieces ≤1.5 cm x 1.5 cm.
- Use thumbnail or fork width as size reference.
- Reduces choking risk by allowing food to pass airway safely.
