Overview

Prospective study evaluates cough reflex tests for detecting silent penetration in older adults, highlighting its clinical utility.

Key Points

This study aims to assess the effectiveness of different cough reflex test modalities for identifying silent penetration and aspiration in older adults.
Prospective study involving 37 patients over 75 years hospitalized for acute conditions.
Used fiberoptic endoscopic evaluation of swallowing to compare results of cough reflex tests with citric acid at varying concentrations.
Cough responses were measured, specifically noting instances of C2 (2 or more coughs) and C5 (5 or more coughs).
Cough reflex test using citric acid at 0.1 mol/L distinguished patients with silent penetration from healthy individuals (p = 0.009; Se: 81.25%; Sp: 71.43%).
Absence of C5 identified patients with silent penetration versus those with detected aspiration (p = 0.026; Se: 81.25%; Sp: 71.43%).
The test is non-invasive and does not require specialized expertise to perform.
