Diabetes, obesity and metabolic syndrome are closely linked to sleep apnea syndrome. Indeed, diabetic and/or obese patients present an increased risk of sleep apnoea syndrome (SAS), with a prevalence estimated at between 10 and 22%, depending on the study, and most of them requiring treatment with Continuous Positive Airway Pressure (CPAP). In this sub-population of patients, only between 40% and 50% benefit from CPAP.

There is therefore an under-referral of diabetic patients to treatment, perhaps linked to the way care is organized, which clogs up the circuit and slows down or even prevents access to care. The investigators would like to test a new organization of care to facilitate and intensify this screening.
