Perspectives of Speech-Language Pathologists About Customary Practices, Knowledge of Thickening Process, and Quality Control of Thickened Liquids

Abstract

Purpose: This survey examines the practice patterns of speech-language pathologists (SLPs) when recommending thickened liquids as part of dysphagia management. It also surveys SLPs' knowledge and learning methods about thickening agents and factors contributing to quality control in service delivery such as staff instruction and familiarity with measurement tools to verify level of texture consistency. Method: The electronic survey was posted to the community groups for SLP Health Care and Special Interest Group 13 Swallowing and Swallowing Disorders (Dysphagia) of the American Speech-Language-Hearing Association given that their members included professionals with interest and experience in dysphagia management. Results: A total of 246 SLPs, primarily with an adult emphasis in dysphagia management, provided survey responses. Respondents generally viewed the use of thickened liquids as a short-term intervention and self-reported that nectar-like (mildly thick) represented their most recommended level of texture modification. Although SLPs' perceived knowledge about thickening agents varied greatly, the majority selected response options that implied a level of understanding for effective interactions with basic care staff or nutrition professionals. Findings highlight a continued reliance on instant thickening products even though staff instruction about preparation remains inconsistent. Conclusions: Quality control concerns persist, including SLPs' limited familiarity and use of measurement tools for characterizing beverage consistency. Outcomes support standardized practices, including professional education activities for SLPs to learn about thickening products, the thickening process, and to educate/instruct in the preparation of thickened liquids for enhancing the nutritional care of individuals who consume them.
