Overview
Clinical practice guidelines by the United States Preventive Services Task Force[1] address screening and do not recommend screening.
However, commercial drivers, operators of heavy equipment, pilots, and other occupations at risk of diurnal sleepiness should be screened by history and physical exam using standardizes questionnaires.
Obstructive Sleep Apnea Screening
- Commercial drivers, operators of heavy equipment, pilots, and other populations at risk from diurnal sleepiness should with be screened with a history and physical exam
- If OSA is suspected, a sleep study should be performed
- For patients with obstructive sleep apnea, screening questionnaires may be useful for preoperative and high risk patients
STOP BANG questionnaire
- Asks about the presence of loud snoring, apneas, excessive daytime sleepiness, and hypertension
- STOP BANG questionnaire combines the STOP questionnaire questions and adds BMI age, and neck circumference (increased sensitivity but decreased specificity compared to STOP questionnaire)
- A score of three or higher has a sensitivity and specificity of 84 and 56 percent for the diagnosis of OSA using an AHI threshold of >5 events per hour, and a sensitivity and specificity of 93 and 43 percent for an AHI >15 [2]

Sleep apnea clinical score (SACS)
- A four-item questionnaire that incorporates neck circumference, hypertension, habitual snoring, and nocturnal gasping or choking to generate a score ranging from 0 to 100
- Scores greater than 15 result in a probability of OSA (defined as an AHI >10 events per hour) of 25 to 50 percent[3]
Berlin questionnaire
- The Berlin questionnaire consists of 10 items relating to snoring, nonrestorative sleep, sleepiness while driving, apneas during sleep, hypertension and BMI
- The results categorize patients as having a high or low risk for OSA
- A high risk score is associated with a sensitivity and specificity of 80 and 46 percent when OSA is defined as an AHI ≥5 events per hour, and 91 and 37 percent when OSA is defined as an AHI ≥15 events per hour[4]

Central Sleep Apnea Screening
There are no current screening guidelines for central sleep apnea.
