Screening Tool for Symptomatic Sleep Apnoea

This algorithm scores the results of two questionnaires and was primarily designed to assess the likely presence of obstructive sleep apnoea causing symptoms (or the presence of significant excessive sleepiness). It was primarily designed to rapidly score a driver screening questionnaire, but can be used outside this scenario with appropriate caution. One of the questionnaires assesses whether sleep apnoea might be present (STOPBANG), and the other assesses whether there is any excessive daytime sleepiness (Epworth Sleepiness Scale). Each questionnaire is scored into three classes (low, medium, high), If the score on either one or the other questionnaire is high, or the scores on both questionnaires are medium or high, then there may be a significant sleep disorder present (such as obstructive sleep apnoea syndrome) and further assessment may be appropriate. As with many simple screening systems, it is not perfect and may sometimes be wrong. Therefore, if there are concerns, then a consultation with a GP or sleep specialist is advised.

Calculate your STOPBANG Score below:

This questionnaire assesses whether sleep apnoea might be a problem. Answer yes or no by clicking on the relevant button. The last question is about the overweight index, or BMI, and can be calculated in any units, just choose the right box for the units used.

This questionnaire estimates your usual level of any sleepiness.
  • How likely are you to doze off or fall asleep in the situations described in the boxes below, in contrast to feeling just tired?
  • This refers to your usual way of life in recent times.
  • Even if you haven't done some of these things recently try to work out how they would have affected you.
