559 Effect of Weekly Text Message Feedback on Continuous Positive Airway Pressure Adherence in Pediatric Obstructive Sleep Apnea

Abstract

Introduction: Continuous Positive Airway Pressure (CPAP) is an effective treatment for Obstructive Sleep Apnea (OSA) in children. However, adherence to CPAP therapy is often suboptimal. CPAP telemonitoring with automated feedback messaging has been shown to improved adherence in adults with OSA, but has not been widely studied as an intervention for children with OSA. This pilot study was conducted to investigate if feedback messaging could similarly improve CPAP adherence in children. Methods: Pediatric OSA subjects (ages 11-17) with poor CPAP compliance or newly prescribed CPAP were selected from an outpatient Sleep Medicine clinic to receive weekly text messages with scripted feedback on CPAP adherence. Patients already meeting adherence goals were excluded from the study. Parental consent was obtained and participants were given the option to have text messages sent to parents or directly to the patient. Adherence was monitored over a four-month intervention period and compared to pre-intervention usage as a selfmatched control. Total hours of use per month and numbers of days used per month were collected through daily remote CPAP monitoring. Average hours per use and average daily use per 30-day period were additional adherence measurements calculated. Data was analyzed using two-tailed paired T-tests with level of significance set at p<0.05. Results: There was no significant change in CPAP adherence (p>.05) after initiation of weekly feedback messaging for the five patients included in the study. No participant, before or after intervention, met the Medicare definition of compliance (??hr nightly use for ??70% of nights) and average adherence declined following intervention. Conclusion: In a small pilot study, weekly feedback text messaging did not improve CPAP adherence in pediatric patients with OSA. This finding contrasts with larger studies in adult patients with OSA that have demonstrated improved CPAP adherence with automated feedback messaging. With the increasing use of telemedicine for CPAP follow-up, new strategies to successfully utilize this approach in the pediatric population may be needed.
