IDDSI Standards Guide for Hong Kong Care Homes

IDDSI Standards in Hong Kong Care Homes: A Complete Implementation Guide

The International Dysphagia Diet Standardisation Initiative (IDDSI) framework has become the globally recognised standard for describing food textures and drink thicknesses for people with dysphagia. In Hong Kong, where more than 50% of elderly care home residents are estimated to have some degree of swallowing difficulty, implementing IDDSI is increasingly seen not as optional best practice but as a regulatory and clinical necessity.

This guide walks care home managers, dietitians, and kitchen supervisors through the full IDDSI implementation process — from initial staff training to day-to-day kitchen workflows and documentation.

Understanding the IDDSI Framework

IDDSI defines 8 levels (0–7) covering both drinks and foods on a single continuum:

- Level 0: Thin (water) - Level 1: Slightly Thick - Level 2: Mildly Thick - Level 3: Moderately Thick / Liquidised - Level 4: Extremely Thick / Puréed - Level 5: Minced & Moist - Level 6: Soft & Bite-Sized - Level 7: Regular / Easy to Chew

Each level has objective physical tests — the fork drip test, spoon tilt test, and syringe flow test — that any trained staff member can perform without specialist equipment.

Why IDDSI Matters for Hong Kong Care Homes

Hong Kong's elderly care sector operates under the Social Welfare Department's Enhanced Bought Place Scheme and related regulatory frameworks. While IDDSI is not yet mandated by statute, clinical guidelines from the Hospital Authority and the Hong Kong Institute of Speech Therapists increasingly reference IDDSI levels as the standard descriptor for diet prescriptions.

From a legal and risk management perspective, care homes that cannot demonstrate a systematic, documented approach to texture-modified food preparation face growing exposure in incident investigations involving aspiration events.

Staff Training: The Foundation of IDDSI Compliance

Successful IDDSI implementation begins with training — not just for kitchen staff, but for care workers, nurses, and management who interact with residents at mealtimes.

For kitchen staff, the training must cover: understanding the 8 IDDSI levels and what each looks and feels like; how to perform the fork drip, spoon tilt, and syringe flow tests correctly; how to document test results; and how to use SeniorDeli texture-modification products (thickeners, gellants, softeners) to reliably achieve target IDDSI levels across different food types.

For care workers and nurses, the key competencies are: reading and understanding IDDSI prescriptions from the clinical team; recognising signs of inadequate texture at meal service; observing residents during meals for signs of difficulty; and escalating concerns promptly.

For managers and supervisors: understanding documentation requirements; conducting spot audits of kitchen IDDSI tests; and maintaining staff competency records.

Kitchen Workflow: From Prescription to Plate

A robust IDDSI kitchen workflow has five stages:

1. Prescription intake: the clinical team (dietitian or speech therapist) assigns an IDDSI level to each resident. This should be recorded in the resident care plan and communicated to the kitchen in writing.

2. Preparation: kitchen staff prepare texture-modified food using validated recipes and approved products. Each meal batch should be prepared consistently, using calibrated measuring tools for thickener dosing.

3. Testing: before service, the assigned IDDSI level should be verified using the appropriate physical test. Results should be logged.

4. Service: food is plated and served at the correct IDDSI level. Labelling at service helps care workers confirm the correct meal reaches each resident.

5. Documentation and review: monthly review of test logs, near-misses, and any adverse events. Annual review of staff competencies.

Product Selection for IDDSI Compliance

Not all texture-modification products are created equal. When selecting products for IDDSI compliance, care home procurement teams should require:

- Published dosing charts per IDDSI level, per drink type (water, tea, juice, milk, soup) - Independent IDDSI test data from a recognised laboratory - Clear instructions for use in Traditional Chinese for Hong Kong kitchen staff - Stable viscosity across temperature ranges typical in care home kitchens

SeniorDeli's thickener, food gellant, and food softener products are IDDSI-tested and documented, with Traditional Chinese usage guides and staff training support available for Hong Kong care homes.

Documentation: Protecting Your Residents and Your Organisation

Good documentation is the backbone of IDDSI compliance. At minimum, care homes should maintain:

- A current IDDSI level prescription for every resident with dysphagia - Daily kitchen test logs with test method, result, and staff sign-off - Staff training records with competency assessment dates - Incident logs for any meal-related adverse events

These records should be retained for the period required by relevant Hong Kong regulations and be readily accessible for SWD inspections.

Getting Started: A Phased Approach

For care homes that are new to IDDSI, a phased approach reduces disruption:

Phase 1 (Month 1–2): Baseline audit — assess current practices, identify gaps, source IDDSI-compliant products and training materials.

Phase 2 (Month 2–3): Staff training — train kitchen supervisors first, then kitchen staff, then care workers. Use SeniorDeli's training materials.

Phase 3 (Month 3–4): Pilot implementation — implement IDDSI in one kitchen unit or wing before rolling out facility-wide.

Phase 4 (Month 4 onwards): Full rollout and ongoing monitoring — extend to all units, establish documentation routines, and schedule quarterly audits.
