Impact of Comparing Treatment Status With Other CPAP Users

The objective of this study is to evaluate whether comparing a patient's own CPAP usage data with that of other patients improves CPAP adherence in patients who have been undergoing long-term CPAP therapy for sleep apnea. Eligible participants are patients who have been on CPAP therapy with remote monitoring of treatment data enabled for at least three months. Participants will be randomly assigned to one of two groups: (1) routine treatment data feedback group, or (2) treatment data comparison group. In both groups, feedback will be provided to participants by mail on monthly basis, including the proportion of days with CPAP usage ≥4 hours per day and the average daily CPAP usage time. In the treatment data comparison group, in addition to this information, aggregated results for all participants (proportion of days with CPAP usage ≥4 hours per day and average daily usage time) and the participant's ranking based on these aggregated data will also be provided as feedback. The observation period will be six months after initiation of the intervention, and changes in treatment adherence before and after the intervention will be assessed.
