Cost-effectiveness Analysis and Conditional Response to the Effect of Positional Devices in Obstructive Sleep Apnea

Hospital Universitario Ramon y Cajal154 enrolled

Overview

The objectives of this study are: * To assess the effectiveness and cost-effectiveness of a vibrating positional device (NightBalance, Philips) in the treatment of positional obstructive sleep apnea compared to conventional CPAP treatment. * To investigate whether a positional device (NightBalance, Philips) avoids supine position after a period of use of the device without actively using the device for a subsequent period of time.

Non-inferiority clinical trial open to patients and investigators, multicenter, randomized and controlled to treatment with positional device (PD) and CPAP to evaluate the effectiveness of treatment of positional obstructive sleep apnea with a PD (NightBalance, Philips) compared to CPAP after 6 months of continuous treatment (first phase) and the permanence of such efficacy after subsequent discontinuation of treatment (second phase). An initial respiratory polygraphy will be performed in all patients and the sleep study will be repeated at 6 months with PD and CPAP. After its withdrawal, in those patients who respond, the respiratory polygraphy will be repeated at one week and one month.

Outcomes

Primary Outcomes

Effectiveness of a positional device (PD) (NightBalance, Philips) compared to continuous positive airway pressure (CPAP) in the treatment of OSA assessed by the intergroup differences in apnea hypopnea index (AHI) measured by respiratory polygraphy (RP)

To evaluate the effectiveness of a positional device (PD) (NightBalance, Philips) compared to continuous positive airway pressure (CPAP) in the treatment of OSA by assessing the apnea hypopnea index (AHI) measured by respiratory polygraphy (RP) after 6 months of treatment in a non-inferiority analysis.

Time frame: 6 months

Secondary Outcomes

Cost-effectiveness of PD in the treatment of OSA compared to CPAP and assessed by the difference in cost between both devices taking into account the AIH measured by RP.

Time frame: 6 months

Cost-effectiveness of PD in the treatment of OSA compared to CPAP and assessed by the difference in cost between both devices taking into account the degree of daytime sleepiness measured by the Epworth scale.

To assess the cost-effectiveness of NightBalance PD in the treatment of OSA compared to CPAP treatment after 6 months of treatment and assessed by the difference in cost between the two treatment methods divided by the difference in effectiveness between the two treatment methods taking into account the degree of daytime sleepiness, measured by the Epworth scale (0-24, where higher scores mean a worse outcome)

Time frame: 6 months

Cost-effectiveness of PD in the treatment of OSA compared to CPAP and assessed by the difference in cost between both devices taking into account the quality-adjusted life years measured by the EuroQol-5D questionnaire

To assess the cost-effectiveness of NightBalance PD in the treatment of OSA compared to CPAP treatment after 6 months of treatment and assessed by the difference in cost between the two treatment methods divided by the difference in effectiveness between the two treatment methods taking into account the quality-adjusted life years, measured by the European Quality of Life 5 dimensions (EuroQol-5D) questionnaire (5 dimensions from 1 to 3 points in each one, where higher scores mean a worse outcome)
