| Abstract | Background: Oropharyngeal dysphagia is highly prevalent among hospitalized geriatric patients. The screening instruments used to date have been evaluated primarily in stroke patients. This diagnostic study aimed to validate a new screening instrument for oropharyngeal dysphagia, the 'Dysphagia Screening Tool for Geriatric Patients' (DSTG), as compared to one of the gold standards, flexible endoscopic evaluation of swallowing (FEES). Materials and methods: Geriatric inpatients admitted to five geriatric hospitals in Germany were consecutively evaluated using both DSTG and FEES in random order and by different evaluators blinded to the results of the other evaluation. In the FEES examination, a score of more than 3 on Rosenbek's Penetration Aspiration Scale was considered evidence of clinically relevant oropharyngeal dysphagia. Sensitivity, specificity and further measures of test performance were calculated for DSTG. Results: The 53 volunteers recruited were on average 85 years of age, 56.6% were women. Twenty patients (37.7%) were diagnosed with dysphagia using FEES. Of these, 12 were screened as positive on DSTG. Of the 33 FEES negative patients, 4 tested positive on DSTG. The following test parameters were calculated for DSTG: sensitivity: 0.60, 95% confidence interval [0.39 0.78], specificity 0.88 [0.73 0.95], positive predictive value 0.75 [0.51 0.90], negative predictive value 0.78 [0.63 0.89], positive likelihood ratio 4.95 [1.85 13.27], negative likelihood ratio 0.46 [0.26 0.79]. In a receiver-operator characteristic (ROC) curve analysis, the area under the curve (AUC) was 0.77 [0.62 0.91]. No adverse events occurred. Conclusion: The DSTG appears to be a valid instrument for screening of oropharyngeal dysphagia in geriatric inpatients. |
