- Abstract
Purpose: Dysphagia is a common symptom experienced by patients with motor neuron disease (MND). The Yale Swallow Protocol (YSP) is a validated screening instrument for identifying patients at risk for aspiration. The purpose of this exploratory cross-sectional, multicenter study was to investigate how the YSP results in identifying aspiration risk in patients with MND in comparison with aspiration observed during a videofluoroscopic swallow study (VFSS). Method: Participants referred for VFSS as part of clinical management were recruited from four specialized MND clinics. All participants were administered the YSP immediately prior to the VFSS by a speech-language pathologist, with results recorded as pass or fail. Aspiration on VFSS was determined using the Penetration–Aspiration Scale (scores 6–8). A 2 × 2 contingency table was constructed to compare results of YSP with those on VFSS. Results: Thirty-one patients with MND (13 males, 18 females; Mage = 64 ± 12 years) referred for VFSS participated in this study. Of the 22 patients who failed the YSP, interrupted drinking was the most frequent reason (65%). Compared to the VFSS, the YSP yielded a sensitivity of 80%, a specificity of 33%, positive predictive value of 36%, and negative predictive value of 78%. Conclusions: The YSP is a simple tool and easy to utilize and has a high sensitivity in identifying aspiration risk in amyotrophic lateral sclerosis. A future investigation with a larger sample size is needed to better investigate the utility of YSP as a screening tool for this population.
