STOP-Bang

Chung F, Yegneswaran B, Liao P, et al. STOP questionnaire: a tool to screen patients for obstructive sleep apnea. Introduced the STOP items and the extended STOP-Bang (adding BMI > 35, age > 50, neck > 40 cm, male sex); a score ≥ 3 was highly sensitive for moderate-to-severe OSA.

Chung F, Abdullah HR, Liao P. STOP-Bang Questionnaire: a practical approach to screen for obstructive sleep apnea. Pooled data: score 0–2 low risk, 3–4 intermediate, 5–8 high; higher scores and specific item combinations improve specificity for severe OSA.

The 2016 ASA practice guidelines for the perioperative management of patients with OSA and the SASM guidance endorse STOP-Bang as a preoperative screening tool.
