NCT01505959
First received: January 5, 2012
Last updated: September 4, 2014
Last verified: September 2014
  Purpose

Targeted population:

Sleep apnea patients at high cardiovascular risk newly treated by CPAP

Hypothesis:

Improvement in blood pressure after 6 months of CPAP treatment might be greater in the telemonitoring arm compared to usual CPAP care.

Main goal:

To compare 6-months blood pressure reduction when Sleep Apnea patients at high cardiovascular risk are randomly allocated to usual CPAP care or a multidisciplinary and coordinated follow-up based on a telemonitoring web platform.

Primary Outcome Measures:
  • Systolic blood pressure evolution by comparing baseline and 6 months measurements [ Time Frame: day 0 and month 6 ] [ Designated as safety issue: Yes ]
    Systolic blood pressure is assessed at day 0 and month 6 in the two groups by home self-measured blood pressure (4 consecutive days)


Secondary Outcome Measures:
  • Objective CPAP compliance at 6 months [ Time Frame: day 0 and month 6 ] [ Designated as safety issue: Yes ]
    CPAP compliance assessed after 6 months in the two groups

  • Diastolic blood pressure evolution by comparing baseline and 6 months [ Time Frame: day 0 and month 6 ] [ Designated as safety issue: Yes ]
    Diastolic blood pressure is assessed at day 0 and month 6 in the two groups

  • Subjective Sleepiness [ Time Frame: inclusion and month 6 ] [ Designated as safety issue: Yes ]
    Sleepiness is assessed with Epworth Sleepiness Scale at inclusion and month 6 in the two groups

  • Fatigue [ Time Frame: inclusion and month 6 ] [ Designated as safety issue: Yes ]
    Fatigue is assessed with Pichot Scale at inclusion and month 6 in the two groups

  • Quality of Life [ Time Frame: inclusion and month 6 ] [ Designated as safety issue: Yes ]
    Quality of life is assessed with SF-12 questionnaire at inclusion and month 6 in the two groups

  • Health status [ Time Frame: inclusion and month 6 ] [ Designated as safety issue: Yes ]
    Health status is assessed with EQ-5D questionnaire at inclusion and month 6 in the two groups

  • Physical activity [ Time Frame: inclusion and month 6 ] [ Designated as safety issue: Yes ]
    Physical activity is assessed with actimetry at inclusion and month 6 in the two groups

  • Cost analysis [ Time Frame: month 6 ] [ Designated as safety issue: Yes ]
    Cost analysis will include all key resources associated with the telemonitoring intervention and related health (referrals, consultations, resource use)


Estimated Enrollment: 936
Study Start Date: February 2013
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Conventional Device: CPAP treatment
Usual CPAP treatment
Active Comparator: Telemedicine Device: CPAP treatment
CPAP treatment with telemedicine system

Detailed Description:

Study procedures:

The telemonitoring system will involve respiratory physicians, home care providers and include regular assessments of home self-measured blood pressure, oximetry, physical activity recorded by actigraphy, CPAP compliance, side effects and residual events.

Secured data transmission to medical staff computers and secured websites will allow easy telemonitoring. Automatic algorithms have been built-up for early adjustment of CPAP treatment in case of side effects, leaks and persistent residual events.

An interim analysis will be performed when 300 patients will be included.
