To investigate the discriminant ability of the eating assessment tool-10 (EAT-10) to detect postswallow residue and aspiration for different consistencies.

Seventy-two consecutive patients with mixed etiology of dysphagia (42 males and 30 females, mean ± sd age of 60.42 ± 15.82) were included. After completing the EAT-10, Fiberoptic Endoscopic Evaluation of Swallowing (FEES) was performed to assess the efficiency and safety of swallowing for the following consistencies: thin liquid, nectar thick, yogurt, and solid. While swallowing efficiency was evaluated using the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS), the Penetration–Aspiration Scale (PAS) was used to evaluate swallowing safety.

The EAT-10 questionnaire significantly identified the patients with residue from those without residue for the following consistencies and anatomic locations: thin liquid residue in the …
