About this study
Official title: A Smart Sleep Apnea Self-management Support Programme(4S) to Improve Apnea Severity and Cardiovascular Health - A Pragmatic Randomized Controlled Trial With Mixed-method Evaluation
OSA is a chronic disease with high prevalence that parallels with increasing obesity. Self-management programmes are perceived to be cost-effective in long-term OSA patient care and can supplement regular medical treatments. The current study attempt to examine the effectiveness of 4S on improving apnea severity, cardiovascular health and quality of life in 4S intervention (4S) group, compared to the general hygiene (GH) control group.
Read the detailed description
OSA is a chronic disease with high prevalence that parallels with increasing obesity. 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 decision-making of treatment strategies, shifting from positive airway pressure (PAP) device-focused to the patient-centered chronic care model has been suggested.
Mobile instant messaging (such as WhatsApp/WeChat) are popular and inexpensive for interactive messaging. Smartphone-based self-management interventions were reported improved self-efficacy and clinical outcomes in patients with chronic diseases. The investigator only found one mobile health application to support CPAP therapy for OSA and one ongoing trial of OSA self-management telematic support to improve CPAP adherence. There is underutilization of mobile technology in patient-centered self-management programmes to improve PAP treatment and lifestyle modifications in OSA.
The current study attempt to examine the effectiveness of 4S on improving apnea severity, cardiovascular health and quality of life in 4S intervention (4S) group, compared to the general hygiene (GH) control group. Questionnaire and simple fitness assessment will be used to assess the effectivness of the intervention at 4-month and 12-month follow-up. Focus group interview will be conducted to collect qualiatative feedback on the intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Smart Sleep Apnea Self-management Support Programme (4S)Behavioural
Also called 4S group
The experimental group will receive usual care and Smart Sleep Apnea Self-management Support Programme (4S). The 4S includes two interview sessions, instant messages, phone calls, continuous personalized chat-based messaging and phone call support and hotline services in relation to self-management. An e-platform will be used for self-monitoring and group sharing sessions will be conducted for experience sharing.
General Hygiene Information (GH)Behavioural
Also called GH group
The control group will receive usual care and general hygiene information (GH). The GH includes two GH sessions, instant messages, phone calls, continuous personalized chat-based messaging and phone call support and hotline services in relation to general hygiene information. An e-platform will be used for self-monitoring and group sharing sessions will be conducted for experience sharing.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in apnea hypopnea index
Apnea hypopnea index will be asssessed by sleep test. The apnea hypopnea index is the number of times of apnea or hypopnea during one night, divided by the hours of sleep. The higher the apnea hypopnea index, the more severe sleep apnea is.
Measured: Baseline, 4 months
Secondary outcomes (26)

Measured: Baseline, 4 months and 12 months
Change in daytime sleepiness
Daytime sleepiness will be measured by a 8-item Epworth Sleepiness Scale with a 3-point Likert scale. Total scores range from 0 to 24. Higher scores reflect greater daytime sleepiness.
Measured: Baseline, 4 months and 12 months
Change in sleep quality
Sleep quality will be measured by a 7-item Insomnia Severity Index with a 4-point Likert scale. Total scores range from 0 to 28. Higher scores reflect greater severity of insomnia.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
OSA is a chronic disease with high prevalence that parallels with increasing obesity. Self-management programmes are perceived to be cost-effective in long-term OSA patient care and can supplement regular medical treatments. The current study attempt to examine the effectiveness of 4S on improving apnea severity, cardiovascular health and quality of life in 4S intervention (4S) group, compared to the general hygiene (GH) control group.

Primary outcome
Change in apnea hypopnea index
Time frame: Baseline, 4 months
Apnea hypopnea index will be asssessed by sleep test. The apnea hypopnea index is the number of times of apnea or hypopnea during one night, divided by the hours of sleep. The higher the apnea hypopnea index, the more severe sleep apnea is.
