Abstract

Objective: Dysphagia is a common condition in medical settings, and thickened liquids are frequently recommended to reduce aspiration risk despite known limitations related to adherence, hydration, and quality of life. This study aimed to examine the criteria medical-based speech-language pathologists (SLPs) use when determining whether thickened liquids are necessary for patients with dysphagia. Method: This study followed a non experimental, descriptive survey design. Clinician decision-making was analyzed through case study responses, multiple choice questions and Likert-scale ratings. Results: Participant responses suggested that instrumental swallowing assessments, including modified barium swallow studies (MBSS) and fiberoptic endoscopic evaluation of swallowing (FEES), were the primary factor guiding recommendations, often outweighing clinician ideology, workplace policies, and prior experience. While patient-specific factors generally had minimal influence, SLPs did consider patient autonomy and quality of life when making recommendations. Conclusion: These findings suggest that although multiple factors contribute to decision-making, they are not weighted equally, with objective instrumental data playing a dominant role.
