Characterizing Oral and Swallowing Function in Older Adults Presenting to the Emergency Department

What this Trial Is About

Researchers are studying oral and swallowing functions in older adults who visit the emergency department to better understand how these functions relate to other health conditions. The study focuses on oropharyngeal dysphagia, a condition involving changes in swallowing that can lead to pneumonia, a leading cause of death in adults over 65. The goal is to explore oral hypofunction, swallowing difficulties, and the bacteria present in the mouth and upper airway using advanced laboratory methods. Participants undergo various non-invasive diagnostic tests during their emergency visit, including a bedside water swallow test to assess swallowing safety, an oral health examination, tongue pressure measurements, chewing function assessment, and respiratory tests using a spirometer. Saliva samples are also collected to analyze saliva composition and microbiome, although saliva collection for microbiota analysis will not be done for participants enrolled after October 22, 2025. During the emergency department visit, which takes approximately 2 to 10 minutes per test, participants complete the assessments and provide saliva samples. The research team evaluates swallowing function, oral health status, saliva characteristics, and respiratory function. These measures help determine the prevalence of swallowing difficulties and oral health problems. The study monitors participant safety and collects data only during the visit, with no long-term follow-up mentioned.
