Obstructive sleep apnea (OSA) among Veterans is a condition that imparts a great burden to the patient in terms of serious co-morbidities and results in a great cost to the VA Health Care System to treat the co-morbidities, which include heart disease, stroke and neuropsychiatric disorders. Positive airway pressure (PAP) is used to treat sleep apnea and studies have shown a poor adherence to treatment. The investigators hypothesize that using wireless technology will lead to early detection of problems of treatment use and will translate into early remedial action which will improve the use and effectiveness of treatment. The investigators will compare two methods. Usual care involves downloading data from PAP machines at designated 3-month intervals, requiring a face-to-face clinician visit. Wireless care involved more frequent monitoring and intervention in the event of anomalies in treatment use or effectiveness.

Further study details as provided by VA Connecticut Healthcare System:

Primary Outcome Measures:
  • Positive airway pressure treatment adherence [ Time Frame: 12 months ]
    Mean PAP use being > 4 hours per night for greater than 70% of nights.

Secondary Outcome Measures:
  • Receiving effective treatment for obstructive sleep apnea [ Time Frame: 12 months ]
    Evaluate whether patients are effectively being treated with PAP or with alternate means of treatment for OSA at the end of 12 months. We will also assess whether the residual number of respiratory events on treatment (residual AHI), regardless of modality used for treatment, is satisfactory, and whether subjective measures of sleepiness (Epworth Sleepiness Scale) and quality of life (Calgary Sleep Apnea Quality of Life Index).

Enrollment: 52
Study Start Date: January 2014
Study Completion Date: December 2016
Primary Completion Date: November 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Usual Care
These patients will be monitored on a 3-month, 6-month, 9-month and 12-month intervals with face-to-face visits. Adherence and efficacy data will only be assessed by the clinician at these intervals.
Device: Monitoring every 3 months by face-to-face visits
Active Comparator: Wireless Care
These patients will be monitored using wireless modems as the method to obtain adherence and efficacy data.
Device: Frequent remote monitoring
