This study compared the predictive abilities of the STOP-Bang and Epworth Sleepiness Scale (ESS) for screening sleep clinic patients for obstructive sleep apnea (OSA) and sleep-disordered breathing (SDB). Forty-seven new adult patients without previous diagnoses of OSA or SDB were administered the STOP-Bang and ESS and were assigned to OSA or SDB risk groups based on their scores. STOP-Bang responses were scored with two Body Mass Index cut points of 35 and 30kg/m2 (SB35 and SB30). The tools' predictive abilities were determined by comparing patients' predicted OSA and SDB risks to their polysomnographic results. The SB30 correctly identified more patients with OSA and SDB than the ESS alone. The ESS had the highest specificity for OSA and SDB.
