Comparing screening tests for pharyngeal dysphagia in stroke patients
Abstract
Screening for oropharyngeal dysphagia (OPD) in stroke patients is necessary as OPD is a major cause for aspiration pneumonia, nutritional imbalance, and dehydration. it has a poor prognosis and a high mortality rate. This study focused on pharyngeal dysphagia, as it can lead to aspiration pneumonia, which is considered the most serious complication of OPD. Furthermore, the pharyngeal phase is an internal process that cannot be observed during bedside examinations, also the pharyngeal muscles’ function, unlike that of the oral muscles, cannot be examined to predict the efficacy of the pharyngeal phase. Therefore, identifying the highly accurate screening test for pharyngeal dysphagia will prevent misdiagnosis, improve patients’ management, and reduce costs of unnecessary instrumental procedures. This study aimed to compare the screening accuracy of the Volume Viscosity Swallow Test (V-VST), Gugging Swallowing Screen (GUSS) and 3 Ounce Water Swallow test (3 Ounce WST) in detecting pharyngeal dysphagia (PD) in stroke patients for better management and outcomes. A cross-sectional analytic study was conducted in the Phoniatrics Unit of the Otolaryngology Department and the Neurology Unit of the Neuropsychiatry Department. A total of 58 stroke patients were recruited and subjected to the Volume-Viscosity Swallow Test, Gugging Swallowing Screen, 3-ounce Water Swallow Test and Fiberoptic Endoscopic Evaluation of Swallowing. A total of 58 stroke patients participated in this study.…
