Impact of a Multimodal Telemonitoring Intervention on CPAP Adherence in Symptomatic OSA and Low Cardiovascular Risk: A Randomized Controlled Trial

One of the major challenges in treating OSA is to achieve adequate CPAP adherence. Telemonitoring has the potential to provide individualized management and early recognition of problems during treatment.What is the effect of a multimodal telemonitoring intervention on treatment adherence, quality of life, and functional status in symptomatic patients with OSA and low cardiovascular risk?In a multicenter, randomized controlled trial, patients newly diagnosed with OSA were randomly assigned to multimodal telemonitoring for 6 months vs usual care (UC). Telemonitoring consisted of built-in electronic alert algorithms for early adjustment of CPAP treatment in case of side effects, leaks, or persistent residual events. The primary outcome was CPAP adherence (in hours per night). Secondary outcomes included daily symptoms such as fatigue and sleepiness, and quality of life measured by using self-reported questionnaires.A total of 206 patients with OSA and a median age of 50.6 years (interquartile range [IQR], 42.1; 58.1 years) were included in the study; they were predominantly male (63%) with a median BMI of 30.6 kg/mIn patients with severe OSA and low cardiovascular risk, multimodal telemonitoring did not increase CPAP adherence. For both the telemonitoring and UC groups, similar improvements in daytime symptoms were achieved.ClinicalTrials.gov; No.: 01796769; URL: www.clinicaltrials.gov.
