In this sense, this project aims to analyze whether CPAP treatment compliance of OSA patients monitored by telemedicine techniques (website and televisits) is similar to that achieved by standard monitoring but more cost-effective. The study design is a multicenter randomized trial with parallel groups and blind final evaluation after CPAP treatment following two different strategies: one through conventional monitoring in the hospital (face-to-face visiting) and another by telemedicine monitoring (non-contact visiting and website).
