Can Sleep Apnea Screening Questionnaire Predict Adverse Events in Endoscopic Studies

Investigators hypothesize that the obese population (BMI ≥30 kg/m2) who might be at higher risk for obstructive sleep apnea (OSA), carries a higher risk of endoscopy associated adverse events. The primary aim of our study is to determine predictors of endoscopy associated adverse events (airway maneuvers and sedation related complications) in the obese population including the use of the STOP-BANG questionnaire (SBQ) and Epworth Sleepiness Scale (ESS). A secondary aim is to determine the impact of referral to sleep medicine clinic and home sleep test ordered from the gastroenterologist if patient was found to be high risk for OSA by the use of validated questionnaires such as SBQ and ESS.
