STOP BANG This has been developed as a screening tool by Professor Frances Chung (Chung F, Subramanyam R, Liao P, Sasaki E, Shapiro C, Sun Y. High STOP-Bang score indicates a high probability of obstructive sleep apnoea. Br J Anaesth 2012).

The primary use for this has been as a screening tool for anaesthetists to use in patients presenting for surgery. The concern is that patients with untreated OSA are more sensitive to anaesthetic, sedative and analgesic drugs. As a result they are more likely to have post-operative problems.

However, this can also be used effectively in Primary Care and because it uses some objective measures it is less open to patient and operator bias. 

 The STOP portion consists of 4 questions:

Do you Snore loudly   YES   NO

(louder than talking or loud enough to be heard through closed doors).

Do you often feel Tired, fatigued or sleepy during the day  YES   NO

Has anyone Observed you stopping breathing during your sleep   YES   NO

Do you have, or are you being treated for, high blood Pressure   YES   NO


The BANG questions are:

BMI greater than 35        YES   NO

Age greater than 50        YES   NO

Neck circumference greater than 40cm    YES   NO 

Gender  male     YES   NO


A score of 0-2 should exclude the possibility of moderate or severe OSA

A score of 5-8 has a high specificity for identifying moderate or severe OSA.
