Sleep apnea risk check

The Berlin Questionnaire, published by Netzer and colleagues in 1999, is the standard primary-care screen for obstructive sleep apnea (OSA). It scores three categories; two or more positive means high risk. Answer for your usual recent pattern. Scoring happens on your device; nothing is uploaded.

The Berlin Questionnaire, published by Netzer and colleagues in Annals of Internal Medicine in 1999, was designed to let primary-care clinicians quickly flag people who need a sleep study for obstructive sleep apnea. In the original study, the high-risk group predicted an abnormal respiratory disturbance index with about 86% sensitivity and 77% specificity.

Scoring looks at three categories: snoring and breathing pauses (positive when 2 of 5 items are positive), daytime tiredness and sleepiness (2 of 3), and high blood pressure or a BMI over 30. Two or more positive categories means high risk.

The Berlin Questionnaire is a screener, not a diagnosis. Confirming or ruling out sleep apnea requires a sleep study; a negative screen does not fully exclude it when symptoms are classic.
