Mobile Health for Chronic Obstructive Pulmonary Disease (COPD).

*The intervention is a mobile health platform (application, ‘app’) provided to participants through the Google Play store for their own personal device or provided through an approved mobile device supplied by the researchers. *Participants will receive 10 educational videos, available at the Lung Foundation Australia website, over the first 5 weeks that range from 6-12 minutes and cover ten topics: 1) Managing your lung disease, 2) How do your lungs work? 3) Managing your breathlessness, 4) Managing treatment options, 5) Questions you can ask your health professional, 6) Who is your healthcare team? 7) Managing your fatigue and energy conservation, 8) Tips for looking after yourself and your condition, 9) Benefits of exercise programs and ongoing support, and 10) Supportive care and end-of-life issues. *Participants will have access to pre-loaded videos on learning to use inhalers properly, approved by the Lung Foundation Australia. *Participants will have access to a daily symptom diary to record daily symptoms and exacerbations. *Participants will have access to an electronic physical activity plan, involving a built-in step counter in the app, which automatically sets incremental goals of increased step counts each week for the first 4 weeks. *Participants will have access to an electronic version of The Prince Charles Hospital's COPD action plan that will guide symptom and exacerbation control through medications that participants have access to. *Participants who smoke will have access to an electronic version of the smoking cessation plan that records and aims to reduce the number of cigarettes smoked down to zero after 6 weeks. This is done by gradually reducing the daily smoking goals, by advising the use of smoking cessation plan which includes medications, and through automated, motivational messages (simple encouragement) sent through the app to the mobile phone. *Participants in the intervention group will be requested to use the app at least once each day. *All the data entries of the participants recorded via the app, such as symptoms, the action plan, and cigarettes, will be automatically uploaded to the online portal and analysed by research staff to assess the patient adherence. If a participant does not adhere to program for two days, alerts will be generated, and automated motivational messages will be sent to the participant via app notifications. The research staff will review the alerts and accordingly contact the participant to troubleshoot the non-adherence. *Participants will be provided a 60-minute, face-to-face training session in using the mobile health application (‘app’) by research staff.
