To the best of our knowledge, this study is the first randomised controlled trial to assess the impact of an educational video on CPAP adherence in a population of patients at increased risk for poor CPAP adherence. We demonstrated that compared with
usual care, a brief video education prior to the sleep study does not lead to improved outcomes. Furthermore, a phone conversation after the sleep study between the patient and the sleep physician had no impact on any of the outcomes. Our study
shows that a simple intervention such as our short educational video is not sufficient to improve a complex behaviour such as CPAP adherence, particularly in a patient population at increased risk for CPAP non-adherence.
