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, and markedly reduce cost to the VA system. The investigators will compare two technologies; storing the data on secure digital cards to follow the patient versus using secure wireless technology to gather the data, a cloud system to store the data, and staff that would be notified in the event of anomalies in treatment use or effectiveness.

Further study details as provided by VA Connecticut Healthcare System:

Primary Outcome Measures:
  • Postive airway pressure treatment adherence [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Mean PAP use being > 4 hours per night for greater than 70% of nights.

Secondary Outcome Measures:
  • PAP treatment efficacy [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Evaluate the effect active continuous monitoring among patients with sleep apnea on mean nightly residual respiratory disturbance index (RDI), Epworth Sleepiness Scale, Sleep Apnea Quality of Life Index (SAQLI) and Functional Outcomes Of Sleep Questionnaire. (FOSQ)

Other Outcome Measures:
  • Treatment costs [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Compare total costs to patients (sleep clinic visits, travel time, work days missed) and the VA system (travel by homecare providers, sleep clinic visits, supplies) of delivery of OSA management at 30 days, 90 days, 180 days and 1 year between patients receiving conventional CPAP management or active continuous wireless monitoring.

Estimated Enrollment: 220
Study Start Date: April 2013
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
