AB Background: Stop Bang(S-B) is a simple questionnaire effective to identify patients at risk for postoperative complications because of obstructive sleep apnea syndrome(OSAS).Aim: To evaluate S-B as a screening tool for OSAS in a European (Greek) population visiting a sleep clinic.Methods: Patients with possible OSAS answered a Greek translation of STOP questionnaire and underwent polysomnography (PSG). BMI, age, neck circumference,and gender (BANG) were documented.Results: Over 4 yr, 1520 patients (75.2%males) had PSG study and compled S-B. Their mean age was 52±14 yr, BMI 32.7±6.96 kg/ m2, neck circumference 41.8±4.3 cm, Epworth Sleepiness Scale (ESS) 11.2±5, Apnea Hypopnea Index (AHI) 33±26.5/h, Oxygen Desaturation Index (ODI) 37.5±29.5 and S-B score 5±1.5. OSAS was diagnosed in 80.9% of patients: 13.5% mild, 18.8% moderate, and 48.5% severe. By S-B scoring 94.3%(1434) of patients were classified as being at high risk of OSAS. For a S-B≥3, the odds ratio (OR) for OSAS (AHI≥5) was 4.1. The sensitivities of S-B model for AHI ≥5, ≥ 15 and ≥ 30 were 96.2%, 92.5% and 98.6%, respectively; the specificities 13.9%,12.6%,10%, the positive predictive values 83.2%, 70.6%, 52.7% and the negative predictive values 45.3%, 70.9% and 88.3%. The area under the ROC curve at AHI≥ 5 was 0.735. S-B had good correlation with Berlin questionnaire (p<0.001), ESS (p<0.001) and ODI (p<0.001).Conclusions: In a sleep clinic S-B is an easy-to-use screening tool that can be used to evaluate patients with high risk of OSAS.
