    STOP-BANG Score for Obstructive Sleep Apnea

    Screens for obstructive sleep apnea.

    INSTRUCTIONS

    Note: The STOP-BANG questionnaire screens for obstructive sleep apnea (OSA) only, not central sleep apnea.

    When to Use
    Pearls/Pitfalls
    Why Use
    • Patients undergoing preoperative evaluation.
    • Unnecessary if a patient has already been diagnosed with OSA or uses CPAP at night.
    • Patients presenting to a clinic setting with symptoms associated with OSA like: daytime drowsiness, snoring, observed periods of nighttime apnea, noisy breathing, etc.

    The STOP-BANG questionnaire is not well-validated in the obstetrical population, a subgroup with increased risk of OSA.

    • The STOP-BANG questionnaire is one of the most widely accepted screening tools for OSA.
    • OSA (obstructive sleep apnea) is associated with increased risk of perioperative cardiopulmonary complications, including critical care admission.
    • Outside the perioperative setting, OSA has significant morbidity and may result in daytime sleepiness, neurocognitive deficiencies, and cardiopulmonary conditions.
    • Perioperative risks associated with OSA may be modifiable through increased monitoring and treatments (i.e., perioperative CPAP).
