When to Assess Swallowing After Stroke
Post-stroke swallowing assessment should begin as early as possible — ideally within the first 24 hours of admission. Approximately 40–70% of acute stroke patients develop dysphagia, and undetected aspiration is a leading cause of aspiration pneumonia, the most common preventable post-stroke complication.
Assessment is urgent when any of the following are present:
- Drooling or inability to manage saliva
- Coughing or choking during or after drinking water
- Hoarse or ‘wet’ vocal quality after swallowing
- Reduced consciousness or impaired alertness
- Facial weakness or unilateral oral motor deficit
Do not offer food or drink until a bedside screen has cleared the patient for oral intake.
GUSS vs EAT-10: Two Different Roles
The GUSS (Gugging Swallowing Screen) and EAT-10 (Eating Assessment Tool) are both widely used in Hong Kong clinical settings, but they serve distinct purposes.
| Feature | GUSS | EAT-10 |
|---|---|---|
| Who completes it | Trained nurse or SLT clinician | Patient or caregiver (self-report) |
| Setting | Acute bedside | Community, outpatient, or home |
| What it tests | Indirect (saliva) then direct (semi-solid, liquid) swallow trials | Perceived swallowing difficulty across 10 domains |
| Output | Severity score 0–20; recommends diet level | Total score 0–40; ≥3 = abnormal, refer to SLT |
| Best for | Acute post-stroke inpatient screening | Monitoring, community triage, caregiver-led tracking |
| Limitations | Requires trained assessor; takes 5–15 min | Subjective; cannot replace clinical assessment |
Key principle: EAT-10 identifies patients who perceive swallowing difficulty; GUSS tests whether swallowing is clinically safe. After stroke, always prioritise GUSS or equivalent clinical screen over self-report tools alone.
3-Step Bedside Swallowing Assessment
For nursing staff and trained caregivers in Hong Kong acute settings, a systematic 3-step approach is used before the speech therapist’s formal evaluation:
Step 1 — Consciousness and Alertness Check
The patient must be alert, able to follow simple commands, and maintain an upright sitting position (≥60° recline). If not alert, remain Nil by Mouth and refer immediately.
Step 2 — Oral Motor and Saliva Screen (Indirect)
- Ask the patient to open the mouth and move the tongue side to side
- Check for lip seal, tongue range, and ability to cough voluntarily
- Observe saliva management: pooling, drooling, or absence of swallowing suggest high risk
- Failure = refer to SLT; do not proceed to water trial
Step 3 — Graduated Water Trial (Direct)
Using a teaspoon, offer 3–5 ml of cold water and observe for:
- Coughing, throat clearing, or wet/gurgling voice within 3 minutes
- Delay in swallow initiation (>2 seconds)
- Reduced laryngeal elevation
If the patient passes with 5 ml, attempt 10 ml, then 50 ml continuous sip. Failure at any stage = NBM + immediate SLT referral.
Referral Triggers to Speech-Language Pathologist
Refer immediately if any of the following apply:
- Coughing or choking during the water trial
- ‘Wet’ or gurgling vocal quality after swallowing
- History of aspiration pneumonia
- Neurological deficit affecting cranial nerves IX, X, XII
- Patient or caregiver reports food sticking, regurgitation, or prolonged mealtimes
- Unexplained weight loss (>5% in 3 months) post-stroke
In Hospital Authority settings, SLT referrals should be placed the same day for any patient who fails the initial bedside screen. Private hospital and community settings should target a maximum 48-hour referral-to-assessment window.
Supporting Stroke Recovery at Home
Once the acute swallowing assessment phase is complete and the patient is discharged, ongoing monitoring is essential. Caregivers can use the EAT-10 monthly to track whether perceived swallowing difficulty is improving, plateauing, or worsening — and flag changes to the SLT at follow-up.

Frequently Asked Questions
Q: Can a nurse perform a swallowing screen without an SLT?
A: Yes. In Hospital Authority acute stroke units, trained nurses perform the initial bedside screen (water test or TOR-BSST). This is a triage screen, not a full clinical assessment. Any patient who fails — or where the screen is inconclusive — must be assessed by an SLT.
Q: Is the EAT-10 validated for Cantonese-speaking patients?
A: A traditional Chinese version of the EAT-10 has been used in Hong Kong clinical research and community settings. Ask your SLT for the validated version; do not translate the English version independently.
Q: How often should swallowing be reassessed after stroke?
A: In acute settings, reassessment typically occurs every 1–2 weeks or sooner if there is clinical change. After discharge, reassessment frequency depends on recovery trajectory — your SLT will advise based on the individual’s progress.
