Development of the Brief Bedside Dysphagia Screening Test – Revised: a Cross-Sectional Czech Study

Abstract

Aim: The purpose of this study was to develop a revised version of the Brief Bedside Dysphagia Screening Test for determining penetration/aspiration risk in patients prone to dysphagia. The priority was to achieve high sensitivity and negative predictive value. Methods: The study screeners conducted bedside assessment of the swallowing function in 157 patients with a neurological (mainly stroke) or an ear, nose, and throat diagnosis (mainly head and neck cancer). The results were compared with a gold standard, flexible endoscopic examination of swallowing. Results: For the neurological subgroup (N = 106), eight statistically significant bedside assessment items were combined into the Brief Bedside Dysphagia Screening Test-Revised (BBDST-R). Cut-off score 1 produced the highest sensitivity (95.5%; 95% confidence interval CI [CI]: 84.9–98.7%) and negative predictive value (88.9%; 95% CI 67.2–96.9%). Conclusion: The BBDST-R is suitable for dysphagia screening in departments caring for patients with neurological conditions.
