Rolling Out IDDSI in a Care Home: A Step-by-Step Implementation Guide

Implementing the IDDSI framework in a care home is one of the highest-impact safety improvements a care organisation can make. It standardises communication about food and liquid consistency, reduces aspiration risk, and provides a documentable quality framework for regulatory compliance. However, care homes face specific implementation challenges compared to hospitals: higher staff turnover, fewer clinical resources on site, more complex dietary needs (multiple residents with different levels), and often limited kitchen equipment.

This guide provides a realistic, step-by-step rollout plan tailored to care home settings.

Step 1: Baseline Assessment (Weeks 1–2)

Before implementing IDDSI, understand the current state:

Resident assessment

• How many current residents have dysphagia (formally assessed or suspected)?
• What level of dietary modification are they currently receiving, and with what terminology (e.g., old UK descriptors: “fork-mashed,” “soft,” “puréed”)?
• How many residents are on thickened liquids, and with what thickener products?
• How many residents have no current dysphagia documentation despite risk factors (age >75, stroke history, dementia, Parkinson’s)?

Action: Request a SLP review of all unassessed residents with risk factors.

Current practice gap

• Does the kitchen have a thickener testing protocol? If so, what method?
• Are IDDSI syringe tests being performed? What syringe type?
• What documentation exists for batch preparation?
• Are there batch record sheets? Are they completed?

Action: Document the gap between current practice and IDDSI standard. This becomes your baseline for audit purposes.

Step 2: Build the Governance Structure (Week 3)

Appoint an IDDSI Lead

One person must own the implementation. In most care homes, this will be the:

• Unit Manager (if sufficiently clinically engaged), or
• Registered Nurse with an interest in nutrition and dysphagia, or
• Visiting SLP or Dietitian (if the home has regular clinical input).

The IDDSI Lead does not need to do all the work but must track progress, chase completions, and escalate barriers.

Identify your clinical support structure

Care homes typically access SLP and dietitian support through:

• Visiting NHS community SLP (UK) or HA-contracted SLP (Hong Kong).
• Private SLP engagement.
• Specialist dysphagia nurses.

Establish contact with the relevant clinicians before the rollout begins — you will need their input for resident assessments and staff training sign-off.

Step 3: Procure Equipment and Materials (Week 3–4)

Minimum equipment required:

• 10 mL Luer slip-tip syringes — stock of 20–50 (reusable with cleaning, or single-use).
• Stainless steel forks — 3–5 designated QC forks (not used for service).
• Timers — 3–5 kitchen timers or stopwatches.
• Thickener products — review and standardise to one or two products (reduces training burden; choose xanthan gum-based for temperature stability).
• IDDSI level labels — pre-printed or hand-stamped for tray identification.
• Batch record sheets — designed and printed.
• Resident-level reference cards — laminated cards showing each resident’s IDDSI food and liquid level, placed in the kitchen and at the dining table.

Step 4: Staff Training (Weeks 4–8)

Training content (all kitchen and care staff)

1. What is IDDSI? The 8-level framework in plain language.
2. Which levels apply to your care home’s residents.
3. How to perform the syringe flow test (demonstration + practise).
4. How to perform the fork pressure test (demonstration + practise).
5. How to complete a batch record sheet.
6. How to identify and respond to a batch that fails the test.
7. Tray labelling system — how to read and verify.
8. What to do if a resident shows signs of aspiration (coughing, wet voice) during the meal.

Training format

• Group session (1 hour) for all kitchen and care staff simultaneously — covers the framework and demonstrates tests.
• Practical sign-off — each staff member demonstrates the flow test and fork test to the IDDSI Lead or SLP before working unsupervised.
• Competency register — record name, date, sign-off by trainer.

Agency and bank staff

Agency workers present the highest training risk. Until a practical solution (e.g., mandatory pre-shift IDDSI induction card, online module completion) is in place, agency staff should not work unsupervised in the dysphagia kitchen section — they should be paired with a fully trained permanent staff member.

Step 5: Kitchen Protocol Implementation (Weeks 5–8)

Update the menu

Classify every menu item at its natural texture level. Identify which items need modification to serve at Level 4 or Level 5, and update recipes with specific preparation instructions (e.g., “Add 30 mL double cream; blend until no lumps; pass through sieve if needed; verify with fork test”).

Introduce batch record sheets

Batch record sheets should be completed for every thickened liquid batch — no exception. Initially, expect compliance to be imperfect; the IDDSI Lead should check sheets daily for the first 2 weeks and provide immediate feedback.

Visual aids

Post the IDDSI level chart (with test interpretation table) on the kitchen wall. Post laminated step-by-step syringe test instructions at the thickener preparation station.

Step 6: Resident-Level Transition (Weeks 6–10)

Translate existing dietary codes to IDDSI

Map the current dietary codes (e.g., “purée,” “soft minced,” “syrup thick”) to the nearest IDDSI equivalent. For each resident, confirm the appropriate level with the SLP — do not assume a mapping without clinical review.

Update care plans

Every resident with dysphagia requires an updated care plan that states:

• IDDSI food level.
• IDDSI liquid level (and thickener product and dose specification).
• Any compensatory techniques.
• Supervision requirements during meals.
• Date of last SLP assessment.

Update kitchen production cards

Individual resident production cards in the kitchen must match the care plan IDDSI levels. These must be updated whenever a clinical level change is made.

Step 7: Audit and Continuous Improvement (Ongoing from Week 10)

Monthly internal audit

• Batch record completion rate (target: 100%).
• Staff competency register — all staff certified, including any new starters.
• Sample kitchen test verification (IDDSI Lead or SLP tests a random batch and compares to batch record).
• Resident care plan currency — all care plans reviewed within the last 6 months.

Incident review

Report any consistency incidents (wrong level delivered, aspiration event, resident refusal of prescribed level) through the incident management system and review at the monthly governance meeting.

Annual external review

Invite the community SLP or dietitian to conduct an annual IDDSI compliance review — test preparations, interview staff, review records. This provides independent verification for the Care Quality Commission (UK) or equivalent regulatory body in Hong Kong.

The IDDSI.org framework provides free downloadable resources for care homes including training slides, batch record templates, and competency assessment tools.
