Abstract

Objectives: To evaluate the diagnostic value of the Epworth Sleepiness Scale (ESS), STOP-BANG questionnaire, and Sleep Apnea Clinical Score (SACS) in identifying obstructive sleep apnea (OSA) among patients with chronic obstructive pulmonary disease (COPD). Methods: A prospective, cross-sectional descriptive study was conducted on 50 patients diagnosed with COPD Group E, outside of acute exacerbation. Diagnosis of OSA was based on polysomnography and the diagnostic performance of OSA was evaluated using ESS, STOP-BANG, and SACS scores. Results: The prevalence of OSA among the COPD patients was 54%, with moderate OSA accounting for 48.2% of cases. The areas under the ROC curve (AUC) for the ESS, STOP-BANG, and SACS scores were 0.843, 0.908, and 0.809, respectively. The optimal cut-off values for OSA diagnosis in this population were ESS ≥ 5, STOP-BANG ≥ 4, and SACS ≥ 8. Conclusion: The ESS, STOP-BANG, and SACS scores are effective screening tools for OSA in patients with COPD, with STOP-BANG demonstrating the highest diagnostic value.
