STOP-BANG Score for Obstructive Sleep Apnea

Screen for obstructive sleep apnea


The STOP-BANG questionnaire was developed in 2008 (Chung et al. 2008) as a pre-operative assessment tool for anesthetists to screen for undiagnosed obstructive sleep apnea, as it may influence airway management operatively.

When studied against gold standard polysomnography in the diagnosis of OSA, the STOP questionnaire alone was 74% and 80% sensitive in detecting moderate and severe OSA. With the addition of the objective BANG criteria, sensitivities for these two profiles increased to 93% and 100% sensitive. The STOP-BANG questionnaire has subsequently been validated in multiple populations, with a systematic review and meta-analysis (Nagappa et al. 2015) confirming a 90%, 94%, and 96% sensitivity in detecting mild, moderate, and severe OSA respectively.

Variable & Associated Points

Using four equally weighted historical questions (STOP) and four equally weighted objective findings (BANG), points are assigned to create an overall score. Scores < 3 predict a low-likelihood of OSA whereas scores ≥ 3 predict a higher likelihood of OSA.
