title: Bronchial auscultation: an effective adjunct to speech and language therapy bedside assessment when detecting dysphagia and aspiration?
abstract: Detection of aspiration by bedside examination has frequently been found to be clinically inadequate when compared with videofluoroscopy (VF) as the gold standard. In Doncaster, UK, a new multidisciplinary approach to bedside assessment was devised using physiotherapists (PT) performing bronchial auscultation (BA) in combination with the speech and language therapists' (SLT) clinical examination of dysphagia. In this study 105 patients referred for VF examination of dysphagia were first tested by the BA team. Comparison was made between the results of the VF team and the results of the BA team in classifying the patients as "aspirating" or at "risk of aspirating." A high degree of agreement was found for risk of aspiration (sensitivity 87%), although specificity was low (37%). BA was highly specific (88%) when confirming the absence of aspiration, but sensitivity to the presence of aspiration was 45%. From the 105 patients tested, the BA team would have failed to modify the diet in only one subject who was aspirating and would have unnecessarily modified the diet of 17 subjects. In conclusion, in the sample population of individuals with complex dysphagia, the BA team approach reliably detected patients identified by VF as at risk of aspiration. In the group of patients identified by VF as aspirating, the BA team proved unreliable in detecting the presence of aspiration, although it did reliably identify patients who were not aspirating. BA is a potentially useful clinical tool which requires further research.
