Brief summary

Moderate to severe obstructive sleep apnea syndrome (OSAS) (HAI hypopnea apnea index ≥ 15) is a common pathology, which affects 6 to 17% of the general population. The Alaska study, which involved 480,000 apneic patients newly fitted with CPAP, showed that 76.9% of patients were still under treatment for one year, 62.9% after two years, and 52.3% after three years. All patients who recently diagnosed with OSAS in the Sleep Disorder Unit (unity de Pathologies du Sommeil et de la Vigilance, CHU d'AMIENS-PICARDIE, FRANCE) and who are requiring CPAP will be included. On the day of their hospitalization for the implementation of the CPAP therapy, patients will answer validated questionnaires to assess their level of motivation and adherence to the initiation of treatment but also to assess their knowledge and understanding of the disease and its treatment. These questionnaires will be repeated at the four-month and one-year follow-up consultations (+/- 21 days). The aim of the study is to identify the prognostic factors of adherence to CPAP, leading to a better understanding and management of patients with sleep apnea syndrome.

Interventions

OTHERquestionary

the patient will complete validated questionnaires, at three periods (at the time of the initiation of the CPAP, and during the 2 planned follow-up consultations: four months and at 1 year) The validated questionnaires are as follows: Illness Perception Questionnaire (IPQ-R), Beliefs about Medicines Questionnaire (BMQ), Morisky Medication Adherence Scale (MMAS), Hospital Anxiety and Depression Scale (HADS), Rollnick Scale.
