Evaluation of the performance of screening tools for dysphagia in older adults: A diagnostic meta-analysis.

This systematic review evaluated the diagnostic accuracy of multiple screening tools for dysphagia in older adults. The analysis covered 30 studies involving 13 tools and 2,697 participants. The results showed that the volume viscosity swallow test performed best in sensitivity, specificity, and area under the curve, making it a recommended screening tool. Other tools have low sensitivity, unstable results or insufficient research and need to be further validated. Overall, this study provides an important reference for the screening of dysphagia in older adults.
