Online Audio-Visual Information on the Treatment of OSA with Mandibular Advancement Devices: Analysis of Quality, Reliability and Contents

The Internet is a preferred source of health information. This study evaluated the quality, reliability and content of online audio-visual information on the mandibular advancement device (MAD) for the treatment of obstructive sleep apnea (OSA). "Mandibular advancement device" was searched on four online platforms. A total of 63 videos (51% from healthcare professionals, 22% from commercial companies, 21% from laypeople, and 6% from hospitals/universities) were evaluated using metrics, the video information and quality index (VIQI), modified-DISCERN, and the Journal of American Medical Association (JAMA) benchmark criteria and contents. VIQI had significantly lower scores for videos uploaded by laypeople (mean 7.92, 95%CI 5.90-9.95) versus healthcare professionals (12.38, 95%CI 11.28-13.47) and commercial companies (11.21, 95%CI 9.61-12.81). The m-DISCERN scores were significantly lower for laypeople (1.15, 95%CI 0.93-1.40) versus healthcare professionals (2.13, 95%CI 1.73-2.52) and hospitals/universities (3.00, 95%CI 1.70-4.30), as well as for commercial companies (1.43, 95%CI 1.13-1.73) versus hospitals/universities. Contents were significantly less complete for laypeople (1.54, 95%CI 0.60-2.48) versus healthcare professionals (3.25, 95%CI 2.66-3.84). The results of the present study suggest that the quality and completeness of online audio-visual information with respect to the use of MAD for the treatment of OSA are generally poor, and the currently available videos, especially those uploaded by laypeople, may determine misinformation and/or unrealistic treatment expectations.
