P067 Patient perceived sleep quality at CPAP titration study as an early indication of short and long-term adherence to CPAP therapy.

BACKGROUND: Untreated obstructive sleep apnoea is associated with morbidity and diminished quality of life. Despite this, adherence to continuous positive airway pressure (CPAP) remains poor. Few studies have examined which factors from CPAP titration study affect adherence, with a paucity that evaluated perceived sleep quality and adherence. METHODS: We hypothesise that patients with better perceived sleep quality, at the time of their CPAP titration study will have greater uptake and adherence to CPAP. We aim to: 1. Compare the change in patients’ perceived sleep quality between diagnostic and CPAP titration studies, and future CPAP adherence at 3 and 12 months. 2. Evaluate the association between patients’ perceived sleep quality at the time of their CPAP titration study with future CPAP adherence at 3 and 12 months. 3. Evaluate factors relating to sleep architecture, and sleep disturbance that affect patients’ perceived sleep quality. Sleep studies were obtained prospectively between 2018 and 2019. Patients completed two questionnaires grading sleep quality post study. PROGRESS TO DATE: This study was approved as a quality activity through the Metro North Quality and Safety Unit (ID 3929). Sleep study and questionnaire data were collated and merged with adherence data. Analysis will begin shortly. INTENDED OUTCOME AND IMPACT: We intend to publish the results of this study in an international sleep journal. Positive findings may improve management of those at risk of poor adherence. Subsequent studies may evaluate the effect of early patient follow up or early motivational interviewing on uptake and adherence to CPAP.
