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.}, publisher = {MDPI}, keywords = {Dysphagia}, keywords = {Tracheostomy}, keywords = {Critically ill}, keywords = {Fiberoptic endoscopic evaluation of swallowing}, keywords = {Blue-dye test}, keywords = {Diagnostic accuracy}, title = {Accuracy of Modified Blue-Dye Testing in Predicting Dysphagia in Tracheotomized Critically Ill Patients}, doi = {10.3390/diagnostics13040616}, author = {Muñoz Garach, Manuel and Moreno Romero, Olga and Ramírez Puerta, Rosario and Yuste Ossorio, Eugenia and Quintana Luque, Francisca and Muñoz Torres, Manuel Eduardo and Colmenero, Manuel}, }
