Telemedicine to Enhance Adherence to CPAP Therapy in Patients With OSAS

Not Applicable

Completed

• Conditions: Obstructive Sleep Apnea Syndrome

• Registration Number: NCT01715194
• Lead Sponsor: Otto D. Schoch

Brief Summary

We hypothesize that the use of telemedicine combined with support interventions by short messages, telephone calls and ambulatory visits to control CPAP treatment during the first month improves adherence and reduces unresolved side effects of therapy.

The primary objective of an OSAS treatment program is to successfully implement indicated CPAP in the highest possible proportion of patients in order to lower the proportion of untreated OSAS in the population. On an individual basis, it has been shown that a longer duration of CPAP use is associated with better outcomes in terms of daytime functioning and in the control of metabolic and blood pressure effects of CPAP. For our study, we have therefore decided to use 2 co-primary endpoints, taking into account both aspects of adherence mentioned. Cardiovascular complications are a major concern in OSAS patients. Effective CPAP treatment has been shown to reduce surrogate measures of cardiovascular risk. We hypothesize that intensified efforts for CPAP adherence with telemedicine has a positive impact on a number of surrogate measures of the cardiovascular risk at 1 and 6 months of treatment.
