Our Research:
At Dysphagia Outreach Project, we believe equitable care begins with evidence and that research should directly benefit the people it’s meant to serve. That’s why our research efforts are focused on real-world challenges faced by individuals with dysphagia, especially those in underserved and low-income communities.
We partner with universities, clinicians, and community members to conduct award-winning studies that not only advance the science of swallowing but also push for ethical, inclusive, and accessible care.
Why It Matters:
Our research isn’t just about publications—it’s about impact. We ask:
✔️ Who’s being left out of care?
✔️ What barriers do patients and providers face?
✔️ How can we do better?
Through data, advocacy, and lived experience, we aim to transform the dysphagia care system—one question at a time.

Maximizing dysphagia care resources: Evaluating SimplyThick EasyMix™ post expiration date to increase equitable access.
Pre-publication study.

This study presents a proof-of-concept study exploring the safety and efficacy of using SimplyThick EasyMix™ beyond its "best by" date to improve health equity in dysphagia care. Using standardized IDDSI syringe testing, six expired batches were evaluated for changes in thickness over time. Results showed a consistent reduction in thickness post-expiration, with moderately thick liquids maintaining viscosity better than mildly thick ones. Additional variables such as temperature and weight were monitored for accuracy. While findings suggest a decrease in consistency over time, further research is needed to determine safety and develop guidelines for redistribution through food banks and nonprofit organizations, including Dysphagia Outreach Project, where maximizing resources without compromising safety is critical.
Through thick or thin: A convergent mixed methods investigation of the use of speech-language pathologist-driven informed consent for texture modified diets in adult dysphagia management.
Doctoral dissertation in progress.
Primary Author: Hillary Cooper, M.A., CCC-SLP, Doctoral Student
Committee Chair: Dr. Corina R. Kaul, Ph.D.
Collaborating Institution: Baylor University
The purpose of this doctoral dissertation is to explore the barriers speech-language pathologists face when obtaining informed consent for texture-modified diets in patients with dysphagia. The research identifies key challenges through a convergent mixed methods approach and provides insights into improving patient-centered care in dietary management.
