Abstract
OBJECTIVE: The Hyodo scoring system during the endoscopic procedure has been proposed as a new tool for evaluating oral intake feasibility. However, the effectiveness of the information obtained from this procedure in predicting aspiration is not fully elucidated. The aim of this study was to assess the significance of clinical factors, including Hyodo scores, for predicting the risk of aspiration.
METHODS: Five hundred and twenty-eight endoscopic swallowing examinations were performed. Clinical factors, including age, sex, disease type, history of aspiration pneumonia, cognitive function, presence of tracheostomy, presence of vocal cord paralysis, consciousness level on the Japan Coma Scale, ECOG Performance Status, serum albumin level and Hyodo score, were obtained for each examination. The relationship between each of these factors and the presence of aspiration during endoscopic procedure was evaluated.
RESULTS: Three hundred and thirty-two patients (62.9%) were scored less than 5, 153 (29.0%) were scored between 5 and 8, and 43 (8.1%) were scored above 8. The number of patients with aspiration was 133 (25.2%). ROC analysis revealed that a cut-off point of 6 for Hyodo score was effective for predicting aspiration, with a sensitivity of 0.65 and a specificity of 0.86. History of aspiration pneumonia (OR 1.87, P<0.001), vocal cord paralysis (OR 2.23, P<0.001), PS≥3 (OR 2.47, P<0.001) and Hyodo score>6 (OR 9.08, P<0.001) were found to be independent predictive factors for aspiration.
CONCLUSION: The Hyodo scoring method was easy for otolaryngologists to perform and the scores were useful for predicting aspiration with moderate sensitivity and high specificity. Hyodo score>6, history of aspiration pneumonia, vocal cord paralysis, and PS≥3 were independent predictive factors for aspiration and that a Hyodo score above 6 was the statistically strongest predictor for aspiration.
