PenetrationAspiration Scale (PAS) was used to substantiate the severity of aspiration if present.ResultsThe test demonstrated both high sensitivity (91%; 95% confidence interval = 70.8-98.9) anddiagnostic accuracy (96%; 95% confidence interval = 87.0-99.5) for detecting aspiration inindividuals with tracheostomy.Conclusion and SignificanceThe Manipal Bedside Swallowing Screening Test is an easy to administer tool that hassufficient sensitivity to detect aspiration in individuals with tracheostomy.Keywords:Tracheostomy, Dysphagia, Aspiration, Protocol, Screening, Videofloroscopy
