STOP-Bang questionnaire in patients hospitalized with acute symptomatic pulmonary embolism

The STOP-Bang questionnaire is a validated screening tool for obstructive sleep apnea (OSA). We conducted this study to validate it among patients hospitalized with acute symptomatic pulmonary embolism (PE). This prospective cohort study enrolled consecutive stable patients with acute PE who underwent an overnight sleep study within 7 days after diagnosis. Our outcomes were: (1) the STOP-Bang questionnaire's utility for risk stratification, (2) the discrimination of the STOP-Bang questionnaire categories, (3) the false negative rate of STOP-Bang questionnaire prediction, and (4) the clinical utility of the STOP-Bang questionnaire to exclude OSA. We also calculated the test performance characteristics to predict OSA. During the study period, 268 patients completed a sleep study. OSA was found in 47% of patients. OSA incidence in low-, moderate-, and high-risk STOP-Bang groups was 22.4%, 48.2%, and 61.5%, respectively (p
