A New Simple Screening Tool-4QT: Can It Identify Those with Swallowing Problems? A Pilot Study

Area of Science:

• Gerontology
• Clinical Medicine
• Speech and Language Pathology

Background:

• Aging populations experience increased prevalence of dysphagia.
• Dysphagia screening is standard in stroke care but not routinely in frail older adults.
• The 4QT swallow screen was developed to address this gap.

Purpose of the Study:

• To evaluate the effectiveness of the 4QT swallow screen in identifying dysphagia in frail older adults.
• To compare the performance of the 4QT with the EAT-10 and a standardized dysphagia assessment.

Main Methods:

• A Quality Improvement project involving 48 frail older adults on an acute frailty ward.
• Screening using the 4QT and EAT-10, followed by assessment by a speech and language therapist (SLT).

Main Results:

• The 4QT demonstrated comparable effectiveness to the EAT-10 (Kappa = 0.73).
• The 4QT showed 100% sensitivity and 80.4% specificity.
• High negative predictive value (100%) but lower positive predictive value (50%).

Conclusions:

• The 4QT is a sensitive tool for screening swallowing problems in frail older adults.
• Its high sensitivity and specificity suggest potential utility, but further evaluation is required.
• The tool's simplicity allows for potential use by all healthcare staff.
