Around one in three patients with Osas is unable to continue with CPAP. The reasons for this are still poorly understood. Patients being assessed for Bariatric Surgery are informed that untreated Osas can increase peri-operative risk. We investigated whether this information had an effect on Cpap use. Over a six month period we identified 22 obese patients (Mean Bmi 49.3) with Osas discovered during assessment for Bariatric Surgery (Osas Bar). Over the same period we identified a group of 33 obese patients (Mean Bmi 42.1) with Osas referred through conventional pathways by General Practitioners and Hospital Doctors (Osas Conv) not under consideration for Bariatric Surgery. Osas was diagnosed by overnight pulse oximetry, clinical interview and Epworth Sleepiness Score (ESS) using established criteria.
