[Dysphagia severity scale]

Area of Science:

• Speech and Hearing Sciences
• Clinical Medicine
• Medical Imaging

Context:

• Dysphagia evaluations lack standardization, hindering consistent patient monitoring and treatment assessment.
• Videofluorographic swallowing studies (VFSS) are crucial for assessing swallowing function.
• Developing a reliable scale is essential for objective dysphagia severity rating.

Purpose:

• To develop and validate a global Dysphagia Severity Scale (DSS) for standardized dysphagia assessment.
• To correlate the proposed DSS with subjective clinical severity ratings.
• To establish a broadly applicable tool for monitoring dysphagia progression and treatment outcomes.

Summary:

• A Dysphagia Severity Scale (DSS) was developed using videofluorographic swallowing studies and clinical ratings.
• The scale incorporates laryngeal penetration/aspiration (P/A) and pharyngeal retention (PR) severity.
• The final DSS score, derived from the higher P/A or PR score, showed strong correlation (r=0.71) with clinical severity.

Impact:

• The proposed DSS offers a standardized, broadly applicable method for assessing dysphagia severity.
• This scale can improve consistency in dysphagia evaluations and treatment monitoring.
• The DSS has the potential to enhance research on dysphagia consequences and recovery trajectories.
