The purpose of this study was to evaluate the psychometric quality and feasibility of measurements for screening dysphagia in older adults to identify the 'right tool' for nurses to use in nursing homes.

A systematic review was done. Electronic databases were searched for studies related to dysphagia screening measurements. A checklist was used to evaluate the psychometric quality and applicability. Tools were evaluated for feasible incorporation into routine care by nurses.

29 tools from 31 studies were identified. Dysphagia screening tools with an acceptable validity and reliability had sensitivity between 68% and 100% and specificity between 52% and 100%. The Gugging Swallowing Screen (GUSS) and the Standardized Swallowing Assessment (SSA) were the tools with high psychometric quality, especially with high sensitivity, that nurses could perform feasibly to identify the risk and to grade the severity of dysphagia and aspiration of nursing home residents.

Results show that GUSS and SSA are reliable and sensitive tools for screening dysphagia which nurses can use in nursing homes. Further research is needed to examine feasibility of screening with identified tools, and also, to establish effective and standardized protocols for these tools so they can be effectively incorporated into routine care.

The purpose of this study was to determine the significant factors for risk estimate of aspiration and to evaluate the efficiency of the dysphagia assessment tool.

A consecutive series of 210 stroke patients with aspiration symptoms such as cough and dysphagia who had soft or regular diet without tube feeding were examined. The dysphagia assessment tool for aspiration was compared with videofluoroscopy using Classification and Regression Tree (CART) analysis.

In CART analysis, of 34 factors, the significant factors for estimating risk of aspiration were cough during swallowing, oral stasis, facial symmetry, salivary drooling, and cough after swallowing. The risk estimate error of the revised dysphagia assessment tool was 25.2%, equal to that of videofluoroscopy.

The results indicate that the dysphagia assessment tool developed and examined in this study was potentially useful in the clinical field and the primary risk estimating factor was cough during swallowing. Oral stasis, facial symmetry, salivary drooling, cough after swallowing were other significant factors, and based on these results, the dysphagia assessment tool for aspiration was revised and complemented.
