EAT-10 vs Yale Swallow Protocol: Choosing the Right Dysphagia Screen

Two tools appear frequently in dysphagia screening conversations: the Eating Assessment Tool-10 (EAT-10) and the Yale Swallow Protocol (YSP). Both are widely cited in clinical literature. Both are described as “dysphagia screens.” But they measure different things, serve different clinical purposes, and are appropriate at different points in the care pathway.

Choosing the wrong tool for the clinical situation — or misinterpreting either tool’s results — can lead to unnecessary speech therapy referrals, missed aspiration diagnoses, or false reassurance.

This page compares both tools across eight dimensions: what they measure, who administers them, their diagnostic accuracy, their limitations, and the clinical scenarios where each excels.

For an overview of all major dysphagia assessment tools, see Dysphagia Screening Tools Compared: EAT-10, GUSS, MASA, MNA-SF.

What Each Tool Actually Measures

EAT-10 (Eating Assessment Tool-10)

EAT-10 is a patient-reported symptom questionnaire. It asks the patient (or their proxy caregiver) to rate 10 statements about swallowing on a scale of 0 (no problem) to 4 (severe problem), with a maximum score of 40.

The 10 items cover:

  1. Swallowing problems that cause weight loss
  2. Swallowing that interferes with eating outside the home
  3. Swallowing liquids being effortful
  4. Swallowing solids being effortful
  5. Swallowing pills being effortful
  6. Swallowing that is painful
  7. Swallowing as a sensory pleasure dimension
  8. Food sticking in the throat during swallowing
  9. Coughing during eating
  10. Swallowing as stressful

A score of 3 or higher is the established clinical cut-off indicating the need for further evaluation.

Critical point: EAT-10 measures the patient’s perception of swallowing difficulty. It does not measure the safety of swallowing. A patient with severe silent aspiration — who aspirates material into the airway without any protective cough response — may score 0 on EAT-10 because they have no symptoms. A patient with oropharyngeal discomfort from acid reflux may score 6 and have entirely safe swallowing.

Yale Swallow Protocol (YSP)

The Yale Swallow Protocol is a bedside clinical examination that combines three components:

  1. Cognitive screen: The patient must be alert and able to follow instructions. The Protocol includes a simple screen for adequate cognitive function — typically assessing that the patient can follow a 2-step command. Patients who cannot follow instructions are stopped at this stage; the protocol cannot safely proceed.

  2. Oral mechanism examination (OME): The clinician visually and tactilely examines the patient’s oral cavity, lips, tongue, and jaw. Specific findings that pause or halt the protocol include: active oral bleeding, significant facial weakness, absent tongue protrusion, or inability to sustain mouth opening.

  3. 90 ml water challenge: The patient is asked to drink approximately 90 ml (approximately 3 fluid ounces) of thin water without stopping, from a cup. The clinician observes for coughing, choking, voice change (wet/gurgling voice quality), or inability to complete the challenge. Any of these findings constitutes a positive screen — indicating the patient may be aspirating and requires formal SLP assessment before oral intake proceeds.

A patient who passes all three components of the Yale Swallow Protocol — alerts, intact oral mechanism, and successfully drinks 90 ml of water without signs of aspiration — is considered to have a low risk of aspirating thin liquids.

Diagnostic Accuracy: What the Evidence Shows

EAT-10 Diagnostic Performance

Published validation data for EAT-10 in various populations (post-stroke, head and neck cancer, Parkinson’s disease, and community-dwelling elderly) shows:12

These figures mean that EAT-10 misses a meaningful proportion of patients with dysphagia (false negatives) and flags some patients who do not have clinically significant swallowing difficulty (false positives). The sensitivity for detecting silent aspiration specifically is substantially lower — patients who aspirate without coughing, by definition, may report no symptoms on EAT-10.

EAT-10 is best understood as a case-finding tool — it identifies patients who report swallowing problems and should be seen by an SLP. It is not a tool that rules out aspiration.

Yale Swallow Protocol Diagnostic Performance

The Yale Swallow Protocol was specifically developed and validated for the detection of aspiration of thin liquids confirmed by videofluoroscopic swallow study (VFSS).34

The low specificity means the protocol generates a substantial number of positive screens in patients who, if assessed by VFSS, would not be confirmed aspirators. Clinically, this is the acceptable trade-off for a safety screen: over-referral is preferable to missed aspiration.

The 90 ml continuous water challenge is intentionally more demanding than protocols using smaller sip amounts. Research has demonstrated that smaller test volumes (3 ml or 5 ml sips) have lower sensitivity for detecting aspiration than a continuous full-volume drink challenge — because compensatory behaviours that a patient can sustain briefly may fail when sustained swallowing is required.3

When to Use EAT-10

Primary clinical uses:

1. Community and outpatient screening. EAT-10 is appropriate for identifying which patients in a community setting — elderly day care centres, outpatient clinics, post-discharge follow-up — would benefit from SLP referral. Its low administration burden and no-risk nature (no water challenge) make it suitable for large-group screening by trained non-clinicians.

2. Serial monitoring of symptom trajectory. Because EAT-10 captures subjective experience, it is useful for tracking whether a patient’s perceived swallowing difficulty is improving, stable, or worsening over time. A patient who scores 8 at hospital discharge and 3 at 3-month follow-up shows a meaningful symptomatic trajectory — even if objective swallowing physiology has not been reassessed.

3. Research and audit. EAT-10 is the most widely validated patient-reported outcome measure in dysphagia research. Using it as an outcome measure allows comparison across studies.

4. When instrumental assessment is not available. In resource-limited settings without access to VFSS or FEES, EAT-10 combined with clinical interview can help prioritise which patients most need onward referral.

Limitations of EAT-10 that must be communicated to users:

When to Use the Yale Swallow Protocol

Primary clinical uses:

1. Acute hospital ward clearance for oral feeding. The Yale Swallow Protocol was designed for the acute care setting — specifically to give nurses a validated, structured method for determining whether a newly admitted patient (post-stroke, post-surgical, newly diagnosed neurological condition) can safely begin oral intake before a formal SLP assessment is available.

2. Post-extubation screening. Patients extubated after intubation of more than 48 hours are at elevated aspiration risk due to muscle deconditioning, laryngeal injury, and residual sedation effects. The Yale Swallow Protocol provides a structured screen before resuming oral diet.

3. Rapid triage when SLP resources are constrained. In high-volume acute wards where same-day SLP assessment is not possible for all patients, a trained nurse using the Yale Swallow Protocol can identify which patients require urgent SLP review versus which can safely begin a modified oral diet while awaiting assessment.

4. When sensitivity is the clinical priority. Any situation where missing an aspiration event would be clinically serious — a patient with multiple pneumonia admissions, a patient in whom aspiration would trigger a significant care decision — justifies using a high-sensitivity screen like the Yale Swallow Protocol over a symptom questionnaire.

Limitations of the Yale Swallow Protocol:

Combining the Two Tools: The Case for Sequential Screening

Rather than treating EAT-10 and the Yale Swallow Protocol as competing alternatives, many clinical settings use them sequentially:

Step 1 — Community or pre-admission: EAT-10 administered as a routine questionnaire at the GP clinic, elderly day centre, or during community nurse visit. Score ≥3 triggers a referral to SLP outpatient or flags for enhanced monitoring on hospital admission.

Step 2 — Acute admission or high-risk ward: Yale Swallow Protocol administered by trained ward nurse at admission or following a clinical event (stroke, aspiration episode, prolonged nil-by-mouth). Determines whether oral feeding can safely commence before the SLP review.

Step 3 — SLP formal assessment: Clinical swallowing examination (CSE) and, where indicated, instrumental assessment (VFSS or FEES). This remains the gold standard and neither EAT-10 nor the Yale Swallow Protocol replaces it. Both tools are screens — a positive result triggers referral, and the SLP assessment determines the clinical dysphagia management plan.

This sequential model reflects practice in Hong Kong Hospital Authority stroke pathway guidance and is consistent with international clinical advisory recommendations.5

The GUSS as a Third Option

For completeness, it is worth noting that the Gugging Swallowing Screen (GUSS) occupies an intermediate position between EAT-10 and the Yale Swallow Protocol. Administered by trained clinicians, GUSS progresses through indirect swallowing assessment (saliva swallow) before advancing through semi-solid, liquid, and solid texture challenges. It assigns a severity score and directly recommends an appropriate diet texture.

GUSS may be preferred over the Yale Swallow Protocol where:

Summary Recommendation

Use EAT-10 when:

Use the Yale Swallow Protocol when:

Neither tool replaces formal SLP assessment — both are entry points to the clinical pathway, not endpoints.

The information on this page is for educational reference and does not constitute medical advice. Dysphagia screening and assessment should be carried out by trained healthcare professionals. Clinical decisions about oral feeding, dietary texture, and SLP referral should follow institutional guidelines and individual patient assessment.
