Dysphagia Suite
Dysphagia calculators
Five cited calculators for dysphagia screening and severity rating. Use the EAT-10 for patient-reported symptom screening, the FOIS or DOSS for functional severity rating, the Penetration-Aspiration Scale for instrumental assessment findings, and the Yale Swallow Protocol for a bedside screen that determines whether oral intake is appropriate to trial.
- EAT-10Self-report 10-item symptom screen for dysphagia. Total ≥ 3 flags elevated risk (Belafsky 2008).
- Functional Oral Intake Scale (FOIS)Ordinal 1-7 clinician rating of current oral intake — from nothing by mouth to unrestricted diet (Crary 2005).
- Dysphagia Outcome and Severity Scale (DOSS)Ordinal 1-7 severity rating combining diet level, independence, and nutrition route (O'Neil 1999).
- Penetration-Aspiration Scale (PAS)Ordinal 1-8 scoring of airway invasion observed on videofluoroscopy or FEES (Rosenbek 1996).
- Yale Swallow ProtocolThree-step bedside screen (cognitive, oral mech, 3-oz water swallow). All pass → PO trial; any fail → SLP referral (Suiter & Leder 2008).
How these tools fit together
The EAT-10 is the fastest symptom screen and is appropriate across outpatient, inpatient, and community settings. The Yale Swallow Protocol is the bedside decision tool when you need to decide whether to initiate oral intake. The FOIS and DOSS are clinician ratings of functional status that are useful for documenting change over an episode of care. The Penetration-Aspiration Scale is reserved for instrumental assessment (videofluoroscopy or FEES) and describes what was seen when material approached or entered the airway.
