Obstructive sleep apnea OSA affects around 12% and 24% of adults in Hong Kong and China Mainland, respectively. Chronic intermittent hypoxia and sleep fragmentation of OSA leads to cardiometabolic and neurocognitive sequelae (e.g. hypertension, diabetes, daytime sleepiness and depression). Long-term, multidisciplinary management involving patients in the decision-making of treatment strategies, shifting from positive airway pressure (PAP) device-focused to the patient-centred chronic care model has been suggested. We designed A Smart Sleep Apnoea Self-management Support Programme (4S) to examine the effectiveness of 4S on improving apnoea severity, cardiovascular health and quality of life in subjects with obstructive sleep apnea (OSA).
To examine the effectiveness of a 4S to improve sleep apnea and cardiovascular health in subjects with (OSA).
To identify patients’ facilitators and barriers of 4S.
To explore the mechanisms of the impacts of 4S on improvements in self-management.
A 2-group randomized controlled trial on overweight and physically inactive subjects with moderate to severe OSA will be conducted with process and outcome evaluation at 4-month and 12-month follow-up. The mixed-effects model analysis will be conducted to compare the difference in changes of outcomes between two groups, by intention-to-treat and complete case analyses. Causal mediation effects, dose-response effect, programme acceptability (patient engagement and program satisfaction), intervention credibility, healthcare utilization will be examined.
The 4S can improve patients’ self-efficacy and responsibility in managing their health and reduce the health service burden from OSA and its related diseases.
