STOP-BANG Questionnaire (OSA screening)
Eight-item screen for obstructive sleep apnea. A score ≥ 5 means high risk of moderate-to-severe OSA.
About this calculator
STOP-BANG is a screening questionnaire for obstructive sleep apnea (OSA) preoperatively and in general practice. Developed by Chung et al. (Chest, 2016). Eight criteria, 1 point each: Snoring, Tiredness, Observed apnea, blood Pressure, BMI >35, Age >50, Neck circumference >40 cm, male Gender. Interpretation. 0-2 – low OSA risk, no further workup. 3-4 – intermediate, consider polysomnography with symptoms or surgery with respiratory risk. 5-8 – high risk, polysomnography to confirm and grade (apnea-hypopnea index AHI). Clinical use. Preoperative screening – patients with STOP-BANG >=5 have higher postoperative respiratory complication risk and need anesthesia adjustments (avoid high-dose opioids, use multimodal analgesia, monitor SpO2 in the first 24 hours). Primary care screening in daytime sleepiness, hypertension, T2DM – especially resistant hypertension (OSA is a major cause). Diagnosis and treatment. OSA confirmation – level I polysomnography (gold standard) or Home Sleep Apnea Test (HSAT) levels II-III in patients without comorbidities. AHI 5-14 – mild, 15-29 – moderate, >=30 – severe. Treatment: CPAP for moderate-severe, weight loss in obesity, positional therapy, mandibular advancement devices for mild-moderate, ENT surgery in selected cases. Limitations. High sensitivity (90%+) at low specificity – many false positives. In women and normal-weight patients STOP-BANG may underestimate OSA – use additional scales (Berlin questionnaire) and sleep monitoring. Does not confirm diagnosis – polysomnography or HSAT is required.
