title: [Profiles of 939 patients with obstructive sleep apnea syndrome treated with continuous positive pressure].
abstract: The aim of this study was to analyze the characteristics of patients on long-term continuous positive pressure therapy for obstructive sleep apnea in order to determine the efficacy, observance, tolerance, degree of patient satisfaction and patient quality of life using the Nottingham scale. A questionnaire was sent to 939 patients treated for at least six months in 11 centers. Factorial analysis of multiple correspondences and two classification analyses were used to establish patient profiles. Factorial analysis evidenced a relationship between patient satisfaction, reduced symptoms, observance and tolerance. The classification analyses distinguished three groups. Group A (n = 596) included primarily men (93%) who were satisfied with the treatment (99%) and showed good observance. Group B (n = 284) was characterized by patient satisfaction, observance, improved symptoms and lower quality of life than group A. Group C was composed of older patients who were satisfied with their treatment and showed good observance but who had no notable improvement in their symptoms. In conclusion, this study pointed out the difficulty in defining which patients with obstructive sleep apnea would benefit most from continuous positive pressure therapy. Good observance is not a sufficient criterion for therapeutic efficacy.
