Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a randomised study to measure the usefulness of a mobile phone adherence application in decreasing healthcare utility due to increased treatment adherence. Participants in the intervention arm will have access to the NPS MedicineWise application (MedicineWise app) in addition to standard care and will be trained by a member of the research team on how to use the app: this training will include navigating the app's functions. Participants in the intervention arm will be tracked on the app for 9 months (duration of the study) after which they can freely use the app for as long as they want as the app is free to download from app stores.

The proposed intervention has three tiers.

Tier 1: in-app medicine dose reminders from the MedicineWise app
Participants will receive in-app reminders (in the form of notifications and audible alarms) when each medicine dose is due to remind them to take their dose. Participants can acknowledge that they have taken their medicine doses in the app by tapping on a “taken” button that is associated with the dose. Information of either the dose being recorded as taken or missed will be registered and recorded by the MedicineWise app.

Tier 2: personalised ‘push’ notification messages from the MedicineWise app
Medications have been categorised as critical or non-critical to the management of heart failure. If a participant has either missed a dose of a critical medication for 24 hours or a non-critical medication for 3 days, they will receive a personalised ‘push’ notification from the MedicineWise app containing one or more of the following messages: reminding them to take their doses; reminding them to interact with their app; emphasizing the importance of adhering with their medication regimen; how to seek help if they are having difficulty with their medication and/or operating the MedicineWise app.
A research team member will examine the extracted dosage taken data during the 24 hours prior and escalate participants to the Tier 3 program as required.

Tier 3: phone call intervention delivered by Medicines Line pharmacists
Participants who do not respond to MedicineWise app notifications (Tier 1 intervention) and ‘push’ notification messages (Tier 2 intervention) will be contacted by a NPS MedicineWise’s Medicines Line pharmacist by telephone to discuss their medicines and medication adherence.
Intervention code [1] 313578 0
Treatment: Devices
Comparator / control treatment
Participants allocated to the usual care arm will receive standard care for their chronic heart failure as determined by their treating physicians, including prescriptions to treat CHF and advice, as well as lifestyle advice. The participants in this group will have no access to a smartphone medication reminder application.
Control group
Active

Outcomes
Primary outcome [1] 318980 0
The primary outcome is the comparison of medication adherence between the two arms. Medication adherence will be measured by self-reported medication adherence tool Self-Efficacy for Appropriate Medication Use Scale (SEAMS).
This self-reported data will also be verified by the data collected from the intervention arm participants whose adherence rate has been captured by the data collected by the NPS MedicineWise application.

Statistical methods / analysis
Sample size calculations are focused on two different measures and were also done assuming equal numbers of participants in each group. The first measure takes into account an absolute increase in mean adherence of 15 %. In this measure, at two tailed 0.05 significance level with a power of 80 % and standard deviation of 35, the number of participants required in each group is 86. In the second measure, the analysis is by comparing proportions of adherence. Previous studies have estimated the adherence to cardiovascular drugs to be up to 60 %. In this measure, a total sample size of 182 participants is needed to provide 80 % power to detect an increase in the proportion of adherent participants from 60 % to 80 %, with a two tailed 0.05 significance level. Therefore, taking the larger of the two sample sizes (91 participants in each arm), and allowing for a 20 % loss to follow up, a total of 220 participants will be recruited in this study with each arm consisting of 110 participants.
