Summary

It aims to compare the effects of a professional -led support programme using a mobile application versus telephone advice on clients at risk of coronary heart disease. A multi-centre, single-blinded, randomized controlled trial will be conducted. 168 Clients who are at risk of coronary heart disease (CHD), able to use a smart phone will be randomized into the App Support group (App group) or the Nursing Telephone advice (NTA) group . All participants will receive same nursing educational briefing related to CHD. The App Group will additional receive an app use to support their self care whereas the NTA group will receive nursing telephone advice for 20 minutes monthly. Health outcomes will be collected at baseline (T0), 1 months (T1), 3 months (T2). Data analysis will be conducted using a Generalized Estimating Equations model to assess differential changes in all outcome variables.

Detailed description

The aim of this study is to test the effects of a professional-led support programme for clients who are at risk of developing CHD on outcomes of total exercise, self-efficacy and self-management behavior, emergency department attendance and hospitalizations, CHD risk factor profile, and quality of life. Over 3 months, the investigators will examine the effect on the App group as compared to the NTA group and the control group of: Total amount of exercise (primary outcome) and secondary outcomes:1) Self-efficacy and self-management behavior; 2)Emergency department attendance and hospitalization frequency;3) CHD risk factor profile (smoking, blood pressure, body mass index, blood lipid level);4) Cardiovascular functional endurance;5)Perceived stress ; and 6) Quality of life. A prospective multi-Centre, parallel, randomized controlled trial (RCT) with two arms - an app support programme (App) group vs a Nursing Telephone advice (NTA) group and a control group - will be adopted. The RCT method follow CONSORT 2010 guideline. 168 subjects will be required (n=84 each group). Subject recruitment will likely take about 14 months. Intervention protocol: 168 Clients who are at risk of coronary heart disease (CHD), able to use a smart phone will be randomized into the App Support group (App group) or the Nursing Telephone advice (NTA) group. All eligible participants will receive same nursing educational briefing related to CHD. The App Group will additionally receive an app use to support their self -care whereas the NTA group will receive a leaflet and a monthly nursing telephone advice ( about 20 minutes per call. The duration of intervention will be about 3 months. Health outcomes will be collected by research assistant at baseline (T0), 1 months (T1), 3 months (T2) at the community Centre or research Centre. Data analysis will be conducted using SPSS and a Generalized Estimating Equations model to assess differential changes in all outcome variables. All the tests will be two-sided and a p-value of \<0.05 will be considered statistically significant. Ethical approval and permission will be sought from the study university and the selected community centres. RCT registration has been obtained from the ClinicalTrials.gov Protocol Registration system (https://clinicaltrials.gov/).

Interventions

Type	Name	Description
DEVICE	App group	In addition to the usual care, the participant will receive a health talk related to CHD care, a CHD app and a briefing from a trained research nurse (A). The app provides features such as structured e-educational contents and supportive features such as knowledge platform and member area.
DEVICE	Nursing telephone advice (NTA) group	All subjects will continue their usual care with prescribed medical treatments and follow-ups if any. By appointment, a trained nurse will provide a health talk related to the CHD care. In addition to the above usual care, three monthly 20-minute telephone follow-ups supplemented by take home leaflet will be provided by a trained research nurse for up to 3 months. Patients can ask about their related health problems, if any. The team has set up a telephone advice guide to support the research nurse in giving phone advice and text messages. .In summary, all two groups will receive from a nurse similar educational content as that related to their CHD and care. The only difference will be the re-enforcement and continual support provided through an app, telephone nursing advice and leaflet.
