Background and Objectives Obstructive sleep apnea (OSA) is associated with varioushealth risks, including hypertension, cerebrovascular disease, myocardial infarction, diabetes,cognitive impairment, and all-cause mortality. While overnight polysomnography (PSG) isthe gold standard for diagnosing OSA, it is costly and time-consuming. The STOP-Bang ques-tionnaire is a convenient tool for OSA screening, but its high sensitivity comes at the expenseof low specificity. The purpose of this study was to investigate the usefulness of combiningthe STOP-Bang questionnaire and a smartwatch capable of measuring oxygen saturation inscreening for OSA. Subjects and Method Of the patients scheduled for PSG due to OSA, 109 patients volun-tarily participated in the study by filling out a STOP-Bang questionnaire during their first visitand wearing a smartwatch during PSG. Results There were 80 males and 29 females, with the patients’ mean age of 45±13.3 years. Based on the apnea-hypopnea index (AHI), 19 patients (17.4%) were normal, 28 (25.7%) hadmild OSA, 23 (21.1%) had moderate OSA, and 39 (35.8%) had severe OSA. When using theAHI threshold of AHI ≥15/h, the STOP-Bang alone showed sensitivity of 85.5% and specifici-ty of 61.7%. Combining the STOP-Bang questionnaire with a smartwatch resulted in a slightdecrease in sensitivity and a significant increase in specificity, yielding the values of 80.5%and 84.4%, respectively. Conclusion A two-step approach using the STOP-Bang and a smartwatch was implementedto enhance the diagnostic accuracy of screening OSA.
