STOP-Bang score for obstructive sleep apnoea
Snoring loudly (louder than talking, or heard through closed doors)

Treated for high blood pressure
BMI >35 kg/m^2

Neck circumference >40 cm
Male sex
Result0 points
Low risk of moderate-to-severe obstructive sleep apnoea.
- Risk category
- Low
When to use
- Preoperative screening for undiagnosed obstructive sleep apnoea to guide perioperative monitoring and anaesthetic planning.
Formula
One point each for: Snoring, Tiredness, Observed apnoea, blood Pressure (treated hypertension), BMI >35, Age >50, Neck circumference >40 cm, male Gender. Score 0-8; 0-2 = low risk, 3-4 = intermediate risk, >=5 = high risk of moderate-to-severe OSA.
Pearls and pitfalls
- A score of >=5 gave the strongest association with moderate-to-severe OSA on polysomnography in the validation cohort.
- STOP-Bang has high sensitivity but modest specificity; a low score is more useful for ruling out OSA than a high score is for ruling it in.
