简要总结
Continuous positive airway pressure (CPAP) is the reference treatment for obstructive sleep apnea syndrome (OSAS) and is effective in improving symptoms of OSAS, reducing risk of accidents and improving quality of life. However, CPAP use is less than optimal. Recommended use is between 6-8 hour per night and a common clinical and empiric benchmark has been defined for CPAP use as an average of 4h per night for 70% of the night. Approximatively 30% of patients discontinue CPAP treatment during the first weeks. Thus, it is very important to identify the factors that influence CPAP adherence during the first weeks of treatment.
Biomedical factors, in particular nose respiratory abnormalities, somnolence complaints and insomnia complaints, have been widely studied but explain only 4 to 25 % of the variance in CPAP use. Interestingly, "self-efficacy" (the confidence to engage in a treatment), was found to explain more than 30 % of the variance in CPAP use.
The SEMSA (Self Efficacy in Sleep apnea) questionnaire is the instrument to investigate self-efficacy related to OSAS and CPAP that has received the most attention. Retrospective studies showed that the factor "self-efficacy" of the SEMSA was related to poor CPAP adherence. Prospective studies showed that the factor "self-efficacy" of the SEMSA at baseline was associated with future CPAP use when it was completed after education information.
A French version of the SEMSA has been validated by investigators in a retrospective study. They have confirmed in France that the factor "self-efficacy" of the SEMSA was related to poor CPAP adherence. No prospective study using the SEMSA has been conducted in French patients with OSAS treated with CPAP. Given the specificity of the French health care system and home care system, it is thus important to evaluate the predictive value of self-efficacy on CPAP adherence in France. The generation of predictive model would enable pretreatment prediction of those likely to have difficulty with CPAP adherence, and would serve as the basis for the development of maximally effective interventions in order to enhance CPAP adherence by patients with OSAS.
详细描述
Using a prospective design, investigators aim to examine the following factors: pre-treatment demographic factors, sleep clinical factors (Somnolence complaints with ESS questionnaire and Insomnia complaints with ISI questionnaire), patients' perceptions of self-efficacy (SEMSA questionnaire), and nose respiratory complaints (NOSE questionnaire).
The objective is to investigate if self-efficacy would be the best predictor of CPAP use during the first month of treatment and at 3 and 6 months after treatment beginning. Impact of demographic factors, sleep and nose complaints will be taken into account.
The study intend to recruit at the sleep clinic 150 patients with newly diagnosed Obstructive Sleep Apnea Syndrome for whom CPAP treatment is indicated.
During the consultation of CPAP treatment initiation, the investigator will present the study and give the informed notice. If the patient agrees to participate, the investigator will notify the non-opposition of the patient in the medical file and confirm eligibility criteria. The patient will then complete 4 questionnaires (ISI, ESS, SEMSA, NOSE).
After initiation of CPAP treatment, the same questionnaires will be sent to the patient 1 month, 3 and 6 months after treatment beginning.
