Introduction: Low adherence to Continuous Positive Airway Pressure (CPAP) treatment is one of the usual problems when treating patients with Obstructive Sleep Apnea (OSA). Educational strategies have been described to increase compliance and prevent patients from abandoning treatment. Objective: To describe compliance to CPAP treatment in patients who participated in an educational program: "School of CPAP". Design: We performed 20 meetings among patients with OSA who were prescribed to initiate CPAP treatment between May 2010 and May 2012. An educational talk and a practical workshop about equipment use were provided to all participants. On June 2012 all the patients were contacted for a telephone standarized survey. We inquired in relation to CPAP availability, adherence, attendance to the program and personal opinion about the CPAP education usefulness. Results: 184 patients were invited to participate. Data from 140 patients were available for analysis (76%). 92 (65.7%) patients were included in the program (group 1) and 48 subjects did not attend the "school CPAP" (group 2). Intention to be treated, defined as initiating CPAP therapy, occurred in 87 (94.5%) patients in group 1 and 38 (79.1%) in group 2. Main causes of non adherence were: intolerance to airway pressure (20.51%); lack of health system coverage (15.38%) and others coverage issues (10.25%). 16 patients who had attended the program abandoned CPAP (69% with transient use) compared to 23 in group 2 (60% with transient use). Comparative analysis showed that 76 patients in group 1 (82.6%) continued using CPAP 8 months after therapy initiation vs. 24 in group 2 (50%). Among patients who adhered to CPAP, loss weight was reported in 21 (27.6%) in group 1 and in 5 (20.83%) in group 2. In the group which adhered to CPAP, 92 patients (92%) reported to feel better or much better and 8 reported to feel the same than at the beginning of treatment. No patient had worsening with CPAP. We asked about day sleepiness in non adherent patients using a 4 level scale. 41% of the group described sleepiness in passive situations, 7% in active situations and 2% in risk situations. Conclusions: 65.7% of patients with Sleep Apnea / Hypopnea Obstructive Syndrome (SAHOS) and CPAP attended the educational program. 96% of them felt that "school of CPAP" was a useful treatment aid. Transient use of CPAP showed a high intention to be treated (89.28%). Nevertheless, actual adherence was different between those who attended the program (82.6%) and those who did not (50%).
