ABSTRACTBackgroundThe availability of a standardised protocol that is exclusively focussed on assessing theswallowing concerns among tracheostomised individuals is limited.ObjectiveTo validate the Manipal Bedside Swallowing Screening Test (MBSST) for assessingaspiration in individuals with tracheostomy using Video Fluoroscopic Swallow Study(VFSS).MethodA total of 53 tracheostomized participants took part in the study where they were screened foraspiration at bedside as well as VFSS across three different consistencies. 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
