Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Push notifications to patients with Heart Logic Score feedback.

Patients in the intervention arm will be registered for a web-app that will reside on their mobile phone home screen. Push notifications will be sent via this mechanism on a weekly basis for a minimum of 12 months following enrolment in the trial. The content of the notification will be determined based on their Heart Logic (HL) score, which will be transmitted via their pre-existing Boston Scientific HL compatible Cardiac Implantable Electronic Device (CIED) Home Monitoring via their Latitude platform. The participants will receive feedback on their HL score and be categorised into 3 groups via a "traffic light system" - green, amber and red. Participants with a normal HL score will be in the green zone, and will receive encouragement. Those with an abnormal HL score will receive a notification advising them of this, and be prompted to complete a symptom screening score. Those without symptoms will be categorized as 'Amber' and their notification will provide them with strategies for risk management, be reminded to take their medications, and given information on red flags to look out for. Those who are identified as having symptoms with an abnormal HL score will be categorised in the 'Red' group and will receive a notification advising the participant to seek medical review within 48 hours.

The intervention will be automated process using the Zedoc platform that has been developed by The Clinician. In the event that push notifications are not read by the participant, the Zedoc platform will alert the investigators and a reminder notification can be sent. Failure to respond following a reminder will result in a phone call to check that there are no technical issues prohibiting delivery of the notifications.

Comparator / control treatment
Usual care (no web-app or weekly push notification).

Participants in the usual care group will have their HL scores collected via home monitoring and in the event of an abnormal HL score alert being generated, their treating electrophysiologist who has been assigned their home monitoring privileges, will receive an alert notifying them that this patient has a HL score in the abnormal range. The electrophysiologist will action these alerts as per their usual practice. This could include a phone call, modification to medications, encouragement to see a GP or booking an early appointment with their treating cardiologist.

Outcomes
Primary outcome [1] 333484 0
Feasibility of the NOTIFY-HF web-app and push-notifications in the remote-monitoring workflow of patients with Heart Logic-enabled Cardiac Implantable Exlectronic Devices (HL-CIEDs). Feasibility as defined by app analytics demonstrated completed app interactions without investigator intervention.
Timepoint [1] 333484 0
30 days, 6 months and 12 months post-commencement of the intervention
Primary outcome [2] 333485 0
Acceptability of the NOTIFY-HF web-app and push-notifications in the remote-monitoring workflow of patients with HL-CIEDs. Acceptability will be assessed through a validated questionnaire - the mHealth Usability Questionnaire (MAUQ).

30 days, 6 months and 12 months post-commencement of the intervention
Primary outcome [3] 333544 0
Effectiveness of the NOTIFY-HF web-app and implementation of push notifications on normalisation of HeartLogic score compared with usual care. This will be assessed by examining the remote monitoring of patients to determine the HL score, in conjunction with a review of patient medical records.
