Predictive Value of Accumulated Oropharyngeal Secretions for Aspiration during Video Nasal Endoscopic Evaluation of the Swallow

Abstract

The purpose of this prospective study was to investigate the predictive value of oropharyngeal secretions by use of 5-point and modified 3-point secretion scales for aspiration of food or liquid and diet recommendation outcomes. One hundred consecutive patients and 4 control subjects participated. The 5-point secretion severity scale correlated highly to aspiration (Spearman's ρ = .516, p < .0001) and to diet recommendation outcomes (Spearman's ρ = .72, p < .0001). Patients who received tube feedings were more likely to demonstrate a higher secretion level than patients who received oral feedings (Pearson χ2 analysis value = 25.461, p < .0001). Patients with a tracheotomy tube tended to demonstrate higher secretion levels than patients without a tracheotomy tube (Spearman's ρ = .446, p < .0001). The relationship of the 3-point secretion severity scale level with aspiration was .488, p < .0001 (Spearman's ρ), and that with diet recommendation outcomes was .746, p < .0001 (Spearman's ρ).
