Reliability of Untrained and Experienced Raters on FEES: Rating Overall Residue is a Simple Task

AbstractThe purpose of this study was to investigate the reliability of residue ratings on Fiberoptic Endoscopic Evaluation of Swallowing (FEES). We also examined rating differences based on experience to determine if years of experience influenced residue ratings. A group of 44 raters watched 81 FEES videos representing a wide range of residue severities for thin liquid, applesauce, and cracker boluses. Raters were untrained on the rating scales and simply rated their overall impression of residue amount on a visual analog scale (VAS) and a five-point ordinal scale in a randomized fashion across two sessions. Intra-class correlation coefficients, kappa coefficients, and ANOVAs were used to analyze agreement and differences in ratings. Residue ratings on both the VAS and ordinal scales had...
