Speech-Language Pathologists' Evaluation of Structural Abnormalities on Videofluoroscopic Swallowing Studies

Area of Science:

• Swallowing Disorders
• Diagnostic Imaging
• Clinical Competency

Background:

• Accurate identification of pharyngeal structural abnormalities during videofluoroscopic swallowing studies (VFSS) is crucial for effective dysphagia management.
• Speech-language pathologists (SLPs) play a key role in screening and interpreting these abnormalities.

Purpose of the Study:

• To assess SLPs' competency in identifying and interpreting pharyngeal structural abnormalities on VFSS.
• To examine factors influencing agreement in management planning and referral decisions.
• To evaluate SLPs' ability to screen for and interpret VFSS findings.

Main Methods:

• Eighty Australian SLPs reviewed 12 VFSS clips featuring various structural abnormalities (e.g., Zenker's diverticulum, cervical osteophytes).
• Participants identified abnormalities, interpreted bolus flow and biomechanics, and proposed management strategies.
• Data were analyzed based on SLP experience and VFSS frequency.

Main Results:

• Median accuracy for detecting abnormality presence was high (90.0%), but specific identification accuracy was lower (53.9%).
• Zenker's diverticulum had the lowest identification accuracy, while cervical osteophytes were recognized more frequently.
• Increased VFSS experience and frequency correlated with better interpretation and identification performance.

Conclusions:

• SLPs demonstrate high accuracy in detecting the presence of structural abnormalities on VFSS, supporting their screening capabilities.
• Variability in specific identification, interpretation, and management planning necessitates targeted training and multidisciplinary protocols.
• Enhanced training and protocols can improve diagnostic accuracy and clinical decision-making in dysphagia management.
