Study type
Interventional
Description of intervention(s) / exposure
“TCC-Heart Failure” comprises a smartphone application which collects and transmits health data (oxygen saturation, blood pressure and weight) to a web-based server, where it can be monitored by a central research team. These data can be used to facilitate early review of participants whose parameters fall outside individualised, preset parameters (preset by the participant’s treating cardiologist). If such an event occurs, the participant will be contacted by a registered nurse, who will escalate the issue to the patient’s cardiologist or nurse practitioner if required.
Further, it provides summary feedback to the participant about their collected parameters and delivers educational messages regarding the management of heart failure via push notifications. Participants will be provided with the smartphone application which they will either download by instruction, or have downloaded for them by a member of the research team. Participants will also be provided with 1) A blood pressure machine 2) A weighing scale and 3) a pulse oximeter. Participants will be provided with Bluetooth enabled devices (where available) so that the data is automatically transmitted to the application. Manual data entry will take place for participants who are not provided a Bluetooth device (due to lack of availability). Participants will be required to provide data daily (where possible). The process will take less than 5 minutes per day. Participants will be requested to enter data daily for a total of 6 months. The intervention is administered by a multicentre research team comprising doctors, nurse practitioners and nurses at the local hospital that the participant is cared for at. Adherence to the intervention can be measured by analysis of the data, as all transmitted readings are available to the research team to view.

Outcomes
Primary outcome [1] 324231 0
A process evaluation comprised of four separate primary endpoints is the overall aim. The first part of process evaluation will be assessed by quantification of how many potential participants were eligible to participate, and how many were recruited, this will be collected from medical records
Timepoint [1] 324231 0
At the completion of the trial (when all participants have been enrolled for 6 months)
Primary outcome [2] 324470 0
To determine app engagement (based on log ins, daily entries for each category of parameter being assessed, additional notes by patients).
Timepoint [2] 324470 0
At the completion of the trial (all participants enrolled for six months)
Primary outcome [3] 324473 0
Documentation of nature and prevalence of alerts, and the management of each. Each alert will be documented in a study database. This endpoint is considered a composite primary outcome.
Timepoint [3] 324473 0
Completion of the trial - when all participants have completed the trial (i.e. all participants have been part of the trial for six months).
Secondary outcome [1] 384121 0
• Total unplanned heart failure-related health presentations - which is a composite of:
o General practitioner visits for heart failure
o Cardiologist visits for heart failure
o Emergency department presentations (with or without admission, including to the short stay unit)
o Hospital inpatient admissions

The endpoint will be assessed by medical record review, review of the heart failure service data, obtaining correspondence from the cardiologist and self-reported patient outcomes.
Timepoint [1] 384121 0
6 months post enrolment
Secondary outcome [2] 384754 0
App managers’ documentation of nature and prevalence of any technical issues that resulted in app malfunction. Each technical issue will be recorded in a database. These issues may either be self-reported by the participant, or identified by the monitoring team when data is not recorded by the participant. This endpoint is part of the primary endpoint

Summary
Brief summary
The primary purpose of the study is to evaluate the implementation of a smartphone-app based model of care. Participants with heart failure will be provided with a smartphone app as well as equipment including a blood pressure machine, weighing scale and pulse oximeter. Participants will use the app to send their results daily to a monitoring team who will check for abnormal readings. Abnormal readings will be discussed with a doctor or nurse who is familiar with the participant, and treatment may be provided if necessary.
