Accuracy of Modified Blue-Dye Testing in Predicting Dysphagia in Tracheotomized Critically Ill Patients Muñoz Garach, Manuel Moreno Romero, Olga Ramírez Puerta, Rosario Yuste Ossorio, Eugenia Quintana Luque, Francisca Muñoz Torres, Manuel Eduardo Colmenero, Manuel Dysphagia Tracheostomy Critically ill Fiberoptic endoscopic evaluation of swallowing Blue-dye test Diagnostic accuracy (1) Background: Diagnosis of dysphagia in critically ill patients with a tracheostomy is important to avoid aspiration pneumonia. The objective of this study was to analyze the validity of the modified blue-dye test (MBDT) on the diagnosis of dysphagia in these patients; (2) Methods: Comparative diagnostic test accuracy study. Tracheostomized patients admitted to the Intensive Care Unit (ICU) were studied with two tests for dysphagia diagnosis: MBDT and fiberoptic endoscopic evaluation of swallowing (FEES) as the reference standard. Comparing the results of both methods, all diagnostic measures were calculated, including the area under the receiver-operating-characteristic curve (AUC); (3) Results: 41 patients, 30 males and 11 females, mean age 61 +/- 13.9 years. The prevalence of dysphagia was 70.7% (29 patients) using FEES as the reference test. Using MBDT, 24 patients were diagnosed with dysphagia (80.7%). The sensitivity and specificity of the MBDT were 0.79 (CI95%: 0.60-0.92) and 0.91 (CI95%: 0.61-0.99), respectively. Positive and negative predictive values were 0.95 (CI95%: 0.77-0.99) and 0.64 (CI95%: 0.46-0.79). AUC was 0.85 (CI95%: 0.72-0.98); (4) Conclusions: MBDT should be considered for the diagnosis of dysphagia in critically ill tracheostomized patients. Caution should be taken when using it as a screening test, but its use could avoid the need for an invasive procedure. 2023-03-27T10:39:16Z 2023-03-27T10:39:16Z 2023-02-07 info:eu-repo/semantics/article Muñoz-Garach,M...
