A Clinical Guide for SLTs in Hong Kong Care Homes

Hong Kong’s approximately 800 residential care homes for the elderly (RCHEs) have an estimated dysphagia prevalence of 30–50% among residents. Speech-language therapists (SLTs) play a central role in systematic IDDSI implementation — extending beyond individual clinical assessment to institutional standard-setting, staff training and quality assurance.

This guide is intended for SLTs providing consultancy or outreach services to care homes, covering the practical considerations of each implementation phase.

Note: This guide provides reference information for Hong Kong’s current regulatory environment and does not constitute legal advice. SLTs should adapt implementation strategies to the specific circumstances of each home.

Institutional Assessment: Pre-Implementation Groundwork

Situational Analysis of the Care Home

Before designing an implementation plan, the SLT should assess the following:

Clinical dimension

• Completeness of existing dysphagia screening records for residents
• Mapping of current dietary terminology to IDDSI levels
• Existing speech therapy service model (outreach, shared, residential) and coverage rate
• Kitchen food preparation capabilities (equipment, cook skill level)

Documentation dimension

• Current format and storage of individual dietary records
• Consistency of care worker mealtime observation recording
• Incident reporting procedures and alignment with SWD requirements

Staffing dimension

• Basic dysphagia awareness among chefs, care workers, nurses and management
• Management commitment to IDDSI implementation
• Available training time and personnel

Building Institutional Commitment

IDDSI implementation requires institutional commitment — clinical advocacy alone rarely sustains change. When presenting implementation recommendations, SLTs should frame the case from multiple angles:

• Compliance risk: SWD documentation requirements are increasingly specific; complete records reduce the home’s legal exposure in adverse event investigations
• Quality endorsement: The HKCSS Care Food Endorsement Scheme is increasingly linked to government procurement scoring and sector benchmarking
• Clinical outcomes: IDDSI implementation is associated with reduced aspiration rates and lower hospital transfer demands at the institutional level

Staff Training: A Tiered Design

Training Tiers by Role

SLTs should design a tiered training programme aligned with the specific responsibilities of each staff group:

Chefs and kitchen staff (skill-focused training)

• Definitions of all 8 IDDSI levels and physical testing procedures:
  • Fork pressure test (Levels 4–6): apply approximately 140g of pressure
  • Syringe flow test (Levels 0–4): 10ml IDDSI-standard syringe, 10-second timing
• Food preparation techniques for each level:
  • Level 4 (Puréed): blend fully and sieve — no particles whatsoever
  • Level 5 (Minced & Moist): maximum particle size 4mm; adequate moisture throughout
  • Level 6 (Soft & Bite-Sized): maximum piece size 15mm; cuttable with fork side
• Differences between xanthan gum and starch-based thickeners; correct dosing by digital scale (never by eye)
• High-risk food identification: mixed-texture foods (watermelon, noodle soups), sticky/chewy foods (glutinous rice), small round foods (whole grapes, lychee)

Care workers (observation and implementation focused)

• Visual recognition of each IDDSI level
• Accessing and interpreting individual dietary records
• Mealtime observation recording (cough frequency, intake estimate, duration)
• Warning signs requiring immediate nurse notification
• Supporting implementation of compensatory strategies (chin tuck position, mouthful size control)

Nurses and supervisors (decision and coordination focused)

• Reading IDDSI diet prescriptions and understanding clinical implications
• Decision pathways and documentation requirements for diet level changes
• Clinical warning signs of aspiration pneumonia
• Emergency choking management and post-incident documentation

Management (institutional level)

• IDDSI framework in Hong Kong’s care home compliance context
• Documentation management requirements and SWD inspection preparation
• Speech therapy service procurement and coordination mechanisms

Standardising Kitchen Procedures

Developing Written Kitchen Standard Operating Procedures

In the consultancy role, the SLT should assist the care home kitchen in developing written SOPs covering:

Pre-service verification

1. Review the day’s list of all residents requiring texture-modified meals and their respective IDDSI levels
2. Confirm adequate stock of food ingredients and thickeners
3. Verify that the blender, sieve and testing equipment have been cleaned

Preparation and testing

1. Prepare each IDDSI level in separate batches — never combine levels
2. After preparing each batch, perform the fork pressure test (Levels 4–6) or visual assessment (Level 3)
3. Prepare thickened drinks by weighing thickener per individual records; allow 1–2 minutes for consistency to stabilise
4. Record all test results in the kitchen preparation log

Pre-service check

1. Label each portion with the resident’s name and IDDSI level (IDDSI standard colour labels recommended)
2. Cross-check labels against the day’s resident list before service

Quality Monitoring Mechanisms

SLTs should recommend that care homes adopt the following quality monitoring structures:

• Monthly kitchen audit: the SLT (or a trained nurse) conducts a monthly IDDSI preparation quality review, including live fork pressure test and syringe flow test demonstrations
• New staff onboarding: an IDDSI foundational module is included in all chef and care worker induction training
• Thickener batch verification: the syringe flow test is repeated whenever a new thickener batch is opened — even within the same brand

SWD Documentation Requirements

Standardised Format for Individual Dietary Records

Written diet prescriptions issued by the SLT should include the following elements to ensure care home documentation meets SWD inspection standards:

Required fields

• Resident name, HKID (last four digits) and bed number
• Assessment date and recommended next review date
• Food IDDSI level (L3–L7) and drink IDDSI level (L0–L4) — documented separately
• Thickener type, brand and grams per 150ml / 200ml of liquid
• Prohibited food list — specific named foods, not generic categories
• Posture requirements (head position, seating requirements)
• Special notes (medication effects on swallowing, eating rate management)
• SLT name, HKSLTA registration number and contact information
• Care home receipt date and nurse acknowledgement signature

Care Worker Mealtime Observation Records

A structured mealtime observation form should include:

Incident Records and Reporting

The following constitute events requiring immediate documentation and reporting per institutional protocols:

Immediate recording (same meal)

• Choking episode requiring nurse intervention
• A resident consuming food above their prescribed IDDSI level (record food type and quantity)
• A choking event requiring first aid (back blows, abdominal thrusts)

Incident report within 24 hours

• Time, location and personnel involved
• Resident’s prescribed IDDSI level and the food actually consumed
• Immediate response measures taken and resident’s response
• Follow-up monitoring plan and SLT notification

SWD notification

• Choking events requiring first aid fall under the category of reportable serious incidents under the Code of Practice for Residential Care Homes (For the Elderly). Care homes should report to SWD within the stipulated timeframe (typically 24 hours).

Pilot Programme Design

Pilot Framework

A structured pilot programme reduces the risk of whole-home implementation failure and provides staff with a staged learning experience.

Pilot resident selection criteria

• 10 residents with existing SLT assessments
• Spanning at least 3 different IDDSI levels (recommended: L4, L5 and L6)
• Avoid residents with unstable conditions or anticipated rapid swallowing function changes
• Prefer residents whose family members are cooperative and informed

Pilot timeline

Pilot success metrics

The SLT should help the care home pre-define outcome metrics:

• Kitchen fork pressure test pass rate (target: 100% of batches pass)
• Change in choking incident rate during the pilot period
• Completeness of care worker mealtime observation records (target: ≥90%)
• Staff IDDSI level recognition accuracy (pre- and post-training comparison)

Frequently Asked Questions (SLT Perspective)

Q: Kitchen chefs say they have no time to perform fork pressure tests. How should this be addressed?

Testing takes approximately 1–2 minutes per batch. The primary obstacle is habit change, not time. Display IDDSI testing cards prominently in the kitchen preparation area, and have chefs perform the test hands-on during training — this makes the speed self-evident. Emphasise that the test record functions primarily as institutional protection in adverse event investigations, not as an assessment of the chef’s professional skill; communicating this directly to the kitchen supervisor is important.

Q: High care worker turnover makes training continuity difficult. What approach works?

Integrate an IDDSI foundational module into all new staff induction programmes (approximately 30–45 minutes). Produce simplified IDDSI visual reference cards for the nursing station. SLTs can assist homes in recording short-form training videos (Cantonese and Putonghua versions) that homes use for new staff induction independently, reducing dependence on the SLT’s physical presence.

Q: A family member requests that a resident be given food above the prescribed IDDSI level. How should the care home manage this?

The SLT should provide a written explanation to the family outlining the aspiration risk and potential consequences (aspiration pneumonia) of the requested food. If the family persists after receiving full information, the care home should have a standard informed refusal form signed by both the family member and a care home representative (nurse-in-charge or home supervisor), and filed in the resident’s individual care record. The care home retains the duty to monitor and document mealtime safety continuously.

Q: A resident admitted from a public hospital has no accompanying IDDSI diet prescription. What should the care home do?

This is a common system-continuity gap. The care home should have a standard protocol: the nurse-in-charge contacts the discharging hospital’s speech therapy department within 48 hours of admission to request the written prescription. Pending receipt of the formal prescription, the most conservative appropriate texture level (puréed or minced) should be used, and no unconfirmed foods offered.
