Protocol - Sleep Apnea - Adult Protocol

Add to My Toolkit
Description:

The questionnaire asks about risk factors for sleep apnea, namely snoring behavior, wake time, sleepiness or fatigue, and the presence of high blood pressure. The protocol begins with information that an individual self-reports on height, weight, age, and sex. The 10 questions address snoring, fatigue, and high blood pressure. An algorithm is provided to classify study participants into high or low risk based on response.

Specific Instructions:

None

Protocol:

Scoring Berlin Questionnaire

The questionnaire consists of 3 categories related to the risk of having sleep apnea. Patients can be classified into high risk or low risk based on their responses to the individual items and their overall scores in the symptom categories.

Categories and scoring:

Category 1: items 1, 2, 3, 4, 5

Item 1: if Yes, assign 1 point

Item 2: if c or d is the response, assign 1 point

Item 3: if a or b is the response, assign 1 point

Item 4: if a is the response, assign 1 point

Item 5: if a or b is the response, assign 2 points

Add points. Category 1 is positive if the 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 is the response, assign 1 point

Item 7: if a or b is the response, assign 1 point

Item 8: if a is the response, 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 30kg/m2.

(BMI must be calculated. BMI is defined as weight (kg) divided by height (m)

squared, i.e., kg/m2).

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.
