Abstract:
Objective:To explore the sensitivity and specificity of the simplified cough provoking test in predicting aspiration among patients with dysphagia.Methods:A total of 115 aspirating patients were evaluated using the simplified cough provoking test. Based on the overt and silent aspiration observed through video fluorography, the sensitivity and specificity of the test for predicting each type were quantified.Results:The subjects presented 44 cases of overt aspiration and 71 of silent aspiration. The simplified cough provoking test found that 36 had a normal cough reflex, 22 had a weakened reflex and 57 had none. When the cough′s strength indicated a normal cough reflex, the sensitivity of the simplified cough provoking test predicting silent aspiration was 70.4% and its specificity was 84.1%. The Youden coefficient was 0.545. When the cough reflex was adjudged as abnormal, the test′s sensitivity was 85.9% in predicting silent aspiration and its specificity was 59.1% with a Youden coefficient of 0.45.Conclusion:The simplified cough provoking test has good sensitivity and specificity in identifying silent aspiration. It can effectively screen populations at risk of dysphagia.
