IntroductionObstructive sleep apnea (OSA) is a prevalent disease associated with significant morbidity and high healthcare costs. Information and communication technology could offer cost-effective management options.ObjectivesTo evaluate an out-of-hospital Virtual Sleep Unit (VSU) based on telemedicine to manage all patients with suspected OSA, including those with and without continuous positive airway pressure (CPAP) therapy.MethodsThis was an open randomized controlled trial. Patients with suspected OSA were randomized to hospital routine (HR) or VSU groups to compare the clinical improvement and cost-effectiveness in a non-inferiority analysis. Improvement was assessed by changes in the Quebec Sleep Questionnaire (QSQ), EuroQol (EQ-5D and EQ-VAS), and Epworth Sleepiness Scale (ESS). The follow-up was 3 months. Cost-effectiveness was assessed by a Bayesian analysis based on quality-adjusted life-years (QALYs).ResultsThe HR group (n: 92; 78% OSA, 57% CPAP) compared with the VSU group (n: 94; 83% OSA, 43% CPAP) showed: CPAP compliance was similar in both groups, the QSQ social interactions domain improved significantly more in the HR group whereas the EQ-VAS improved more in the VSU group. Total and OSA-related costs were lower in the VSU group than the HR. The Bayesian cost-effectiveness analysis showed that VSU was cost-effective for a wide range of willingness to pay for QALYs.ConclusionsThe VSU offered a cost-effective means of improving QALYs than HR. However, the assessment of its clinical improvement was influenced by the choice of the questionnaire; hence, additional measurements of clinical improvement are needed. Our findings indicate that VSU could help with the management of many patients, irrespective of CPAP use.

BackgroundCurrent continuous positive airway pressure (CPAP) devices can be monitored remotely; however, in-person visits are kept for clinical follow-up in order to promote CPAP use and resolve potential side-effects. Mobile health is a promising way to provide remote and easy clinical control for CPAP follow-up and support. We aimed to evaluate the feasibility and acceptance by obstructive sleep apnoea (OSA) patients and healthcare professionals of a newly designed mobile app (Appnea-Q) to promote clinical control through a self-monitoring tool for patients with CPAP supervised by sleep professionals.MethodsAppnea-Q incorporates a simple follow-up questionnaire with automated responses, together with frequent problems and lifestyle recommendations sections. Feasibility, acceptance and usefulness were assessed. First, an internal validation was performed during outpatient CPAP follow-up visits with sleep professionals from various sleep units. Second, an external validation was performed in a subgroup of 15 patients at home.ResultsMost patients (n=75) considered the app useful and were willing to use it and recommend it (72–88%). Up to 64.87% agreed on its capacity to reduce hospital visits. Appnea-Q was rated as acceptable (79.37±19.29) by the system usability score. Sleep professionals (n=30) concurred on its usefulness for OSA patient follow-up, particularly during the first month of CPAP therapy. The external validation showed its feasibility among 11 out of 15 patients and their data were received accordingly on the professionals' web platform.ConclusionsAccording to our validation process, and the viewpoints of the patients and professionals, our new mobile app is a feasible and well-received tool for personal OSA management. Future clinical trials should substantiate its performance and cost-effectiveness in the clinical arena.

Obstructive sleep apnea (OSA) is a common disease that leads in notorious symptoms and comorbidities. Although general measures are important, continuous positive airway pressure (CPAP) is the best treatment option. However, compliance can be suboptimal and telemedicine may play a role to improve it. Areas covered: Review authors searched EMBASE, PubMed and Cochrane data bases using the following keywords: continuous positive airway pressure, Obstructive sleep apnea, telemedicine, respiratory telemedicine, information and communication technology. Papers published between 2000 and 2016 in English language were considered. Expert commentary: To improve OSA management, there is a pressing need to develop new cost-effective strategies, particularly those related to OSA treatment, from measures such as lifestyle changes to CPAP use. Two broad strategies should be implemented: 1) adequate pre-, peri-, and post-titration measures to ensure correct diagnosis, adequate training, and appropriate support during follow up; and 2) the use of technological advances including both the optimization of CPAP devices and the use of telemedicine, specially focused on the first days or weeks of treatment. Telemedicine can help with these processes, especially when it is personalized to the needs of each patient group.
