The Berlin questionnaire is a simple screening tool used by physicians to screen for Sleep Apnea. It was developed in Berlin, Germany by a group of Doctors in 1998.

Normally the patient is asked to fill out the questionnaire by either their Family Doctor or the Sleep Center prior to a Polysomnogram being scheduled.

There are normally 10 questions covering Snoring, Fatigue, and High Blood Pressure. Also height and weight are asked. Each question is scored to give an overall risk rating.

Scoring the Questionnaire is as follows:

Category 1:

items 1, 2, 3, 4, and 5

Item1: If Yes selected, assign 1 point

Item 2: if c or d selected, assign 1 point

Item 3: if a or b selected, assign 1 point

Item 4: if a selected, assign 1 point

Item 5: if a or b selected, assign 2 points

Add points. Category 1 is positive if total score is 2 or more points.

Category 2:

items 6, 7, 8 (item 9 should be noted separately).

item 6: if a or b selected, assign 1 point

item 7: if a or b selected, assign 1 point

item 8: if a is selected, assign 1 point

Add points. Category 2 is positive if the total score is 2 or more points.

Category 3: is positive if the answer to item 10 is Yes or if the BMI of the patient is greater than 30(kg)/m2).

(BMI is defined as weight (kg) divided by height (m) squared).

Or if your math dumb like me, you can search the internet for a BMI chart.


High Risk: if there are 2 or more categories where the score is positive.


Low Risk: if there is only 1 or no categories where the score is positive.


Additional Question: item 9 should be noted separately.
