Global Self-management Telematic Support for Patients With Obstructive Sleep Apnea. (TELESAS)
Global Self-management Telematic Support for Patients With Obstructive Sleep Apnea-hypopnea Syndrome, CPAP Treatment and Forecast of Poor Compliance.
Study Overview
Status
Detailed Description
Low CPAP compliance in OSAHS could mean that its possible cardiovascular benefits are not achieved. Telemedicine can be an effective tool to increase CPAP compliance with low cost.
The researchers propose to carry out a randomized study about patients with severe OSAHS and few symptoms, who are expected to have low CPAP compliance.
The main objective is to evaluate if a telematic control and self-management program can increase the compliance with CPAP treatment compared to conventional follow-up, getting at least 90% of patients to use CPAP ≥ 4 hours per day.
Sixty patients from the Pneumology departments of two hospitals, diagnosed with severe OSAHS and with few symptoms (Epworth Sleepiness Scale ≤10) will be randomized to two follow-up groups, telematic and conventional, for 6 months. Patients in the intervention group (telematic monitoring) will collect variables related to symptoms of sleep apnea and side effects of CPAP treatment, using their own smartphone or a tablet provided during the study if they prefer. Other variables as the hours per day of CPAP use, leaks and residual apnea-hypopnea index (AHI) will be transmitted daily and automatically from latest generation CPAP. All information will be processed and each variable will generate alarms and instructions for each patient, allowing the self-management and an early solution of the possible problems related to the treatment. Alarms may also be generated in the database if the professional intervention is necessary.
In addition, before starting CPAP treatment and after six months of treatment, patients will be monitored during a week with a watch-like device. Variables related to circadian rhythm will be collected and analyzed to know the effect of CPAP treatment in both groups (control and intervention groups).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Control arm
Usual follow-up in Healthcare System for patients with obstructive sleep apnea and CPAP treatment
|
According to the SEPAR regulation, patients treated with CPAP should be evaluated by the pulmonologist one month after beginning treatment, every 3 months during the first year, every 6 months during the second year and annually from the third year.
|
Experimental: Intervention arm
Usual follow-up in the Healthcare System for patients with obstructive sleep apnea and CPAP treatment and a telematic control and self-management program
|
According to the SEPAR regulation, patients treated with CPAP should be evaluated by the pulmonologist one month after beginning treatment, every 3 months during the first year, every 6 months during the second year and annually from the third year.
During 6 months with CPAP treatment, patients must complete some questionnaires about the presence of refreshing sleep and side effects with the frequency established, using a computing application. Patients can download this application on their own smartphone but, if they prefer, they can be provided with a tablet during the study with this application installed. A set of variables will be collected using an automatic and wireless transmission from latest generation CPAP to control the CPAP compliance and tolerance. All data will be processed in a platform to generate alarms, which will be controled daily by a researcher, as well as solutions to the problems presented during the monitoring. |

Efficacy of the treatment according to the change in sleepiness
Time Frame: Six months
|
To compare the efficacy of the treatment using the change of the Epworth Sleepiness Scale score in both arms and between them. This scale is a self-administered questionnaire and patients must rate their usual chances of dozing off or falling asleep while engaged in eight different daily activities. The possible answers for each situation and their scores are: 0 = would never doze; 1 = slight chance of dozing; 2 = moderate chance of dozing; 3= high chance of dozing. The Epworth Sleepiness Scale score is the sum of these 8 items scores and it can be interpreted as follows: 0-5 = lower normal daytime sleepiness; 6-10 = higher normal daytime sleepiness; 11-12 = mild excessive daytime sleepiness; 13-15 = moderate excessive daytime sleepiness; 16-24 = severe excessive daytime sleepiness. |

Change of quality of life using the change in the EuroQol-5 dimensions-3 levels questionnaire.
Time Frame: Six months
|
To compare the change of quality of life before and after the follow-up in both arms and between them, using the change in the EuroQol-5 dimensions-3 levels questionnaire.
This is a standardised measure of health status that comprises a descriptive system and a visual analogue scale.
The first comprises 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Each dimension has 3 levels: 1 = no problems; 2 = some or moderate problems; 3 = extreme problems.
The health state is defined by combining one level from each dimension (5 digit code).
This descriptive system is converted into a single index value facilitating comparisons and the calculation of quality-adjusted life years (QALYs).
The visual analogue scale records the respondent's self-rated health on a 20 centimeters vertical, visual analogue scale with endpoints labeled as: 100 = the best health you can imagine and 0. = the worst health you can imagine.
