RESUMO
INTRODUCTION: The most commonly used treatment for obstructive sleep apnea syndrome (OSA) is the application of continuous positive airway pressure (CPAP) during sleep. However compliance with this treatment is frequently below 70%. METHODS: The main aim of this study was to evaluate the feasibility of an educational intervention (EI) delivered in phone calls made to OSA patients (n=66) treated with CPAP by a home care provider (SADIR). The educational intervention consisted of five sessions of telephone based counseling intervention by appropriately trained staff delivered on day 3, 10, 30, 60 and 90 after initiation of treatment. Secondary objectives were to compare, using a case-control design, CPAP compliance of OSA patients (n=133) with or without EI. RESULTS: Ninety-eight percent of patients accepted the intervention to participate in the study. Fifty-seven patients (86%) received the full intervention program and 44 patients (66%) strictly respected the pre-defined timings per protocol. A higher adherence to CPAP at six months was observed in the EI group compared to patient without EI (94% versus 81%) (P<0.05). CPAP compliance at three months was 54minutes higher in the EI group compared to the control group (4h39±2h17 and 3h45±2h45 respectively) but this difference was not statistically significant. CONCLUSION: An educational intervention dispensed by phone is applicable and would have an impact on CPAP compliance. Its efficacy on long-term compliance has to be confirmed in a larger group using a randomized procedure.
