Study summary

While continuous positive airway pressure (CPAP) is the gold standard treatment of obstructive sleep apnea (OSA), this therapy is often discontinued or not used optimally. The adherence risk indicator (ARI) is a statistical model based on answers from a questionnaire. The data collected from this trail allows for closer monitoring of at-risk patients. For the study, participants are provided with a questionnaire prior to starting CPAP therapy for OSA. Participants will be provided with a GSM (Global System for Mobile communication) modem to allow transmission of their CPAP data. Participants data will be retrieved at 7, 14, 21, 30 and 90 days to test the accuracy of the ARI prediction. At the conclusion of the study the GSM unit is returned, and participants continue with CPAP therapy as instructed by their healthcare provider.

What researchers measure

Primary outcomes

  1. CPAP Therapy Adherence

    Adherence is measured by the amount of CPAP use (e.g. good adherence was defined as use of greater than or equal to 70% of nights for greater than 4 hours per night). CPAP data was remotely collected and analyzed from the data reports generated by data collection.

    Time frame: 90 days
