Berlin Questionnaire
This is the Berlin Questionnaire. It is a simple apnea screening tool used by most hospitals for pre-diagnosing apnea among inpatients. Next to life partner referral it is one of the most proficient tools practitioners have for pre-diagnosing apnea.
A friend of mine explained that the way it works is as follows: "The highlighted answers are PROOF positive answers for all categories. Snoring alone is not enough to warrant a study; however a witnessed apnea is. This can be witnessed by anyone. High blood pressure or a BMI over 30% would warrant a study. Without any of the above you must have a positive > 2 in the first 2 categories to warrant a study. Thus you must snore loud and have daytime fatigue in which you could nod off in dangerous situations."

It looks as if you need 2 or more "Category 1" positive answers to warrant a study. But my friend told me that "a witnessed apnea" is enough to warrant a study. But how can that be if the witnessed apnea question, which is "Has anyone noticed that you quit breathing during your sleep?" is just one "Category 1" question? Just trying to understand how this thing operates in practice.

Screening for apnea is basically jumping through hoops for insurance. Witnessed apnea shoul be in it's own catagorie or in 3 with BMI and blood pressure. This type of screener is not perfect but it is fairly accurate as long as people answer honestly.

This is one of three types of questionaires. This one is considered the most clinical of the three and has the least amount of subjective data. No matter which questionaire used the real issue is to have patients answer honestly.

Let's say hypothetically a patient had sp02 desaturations and witnessed snoring. would that alone be enough to warrant a sleep study?

Yes it would the documented desaturation with witnessed snoring would be enough. Documentin oxygen levels is not a requirement for a sleep study so it is not on the questionaires.

If you could record both the desats and the snores it would be even better. A good sleep doc could interpret alot by both of these things.

how much desat is too much desat?

your looking for a 4% or greater. Anything below 70% is probably a false reading as most oximeters are not rated below that.

Thank you very much for posting this. I am of the opinion that this is very interesting and besides this I had no idea that they are using such a questionnaire. I think I have to ask my friend if he knows something about this questionnaire.
