Prediction of self-reported dyspnea in patients without delirium using the Respiratory Distress Observation Scale.
AUCs for the Respiratory Distress Observation Scale as a predictor of self-reported dyspnea in patients without delirium. For the prediction of self-reported dyspnea, the RDOS AUC was 0.81 (95% CI 0.67–0.97). The optimal cutoff was 1 in this study, with sensitivity = 0.89 and specificity = 0.61. For the original cutoff score of 3, the sensitivity was 0.56 and specificity was 0.95. AUC, Areas under the receiver operating characteristic curves; 95% CI, 95% confidence interval.
