Description of intervention(s) / exposure
We will conduct a two parallel-arm, type 2 hybrid randomised controlled trial to evaluate the impact of Smart-HF on quality of life and other secondary outcomes including reducing readmission to hospital. Enrolled patients classified with a high risk of hospital readmission and/or death - i.e., equal to or greater than the median of predicted risk, 33% based on the TAS-Help study algorithm developed by CIs Marwick and Huynh - will be randomised to either usual care or Smart-HF plus usual care, with stratification by study site and type of HF (reduced or preserved ejection fraction).
The intervention arm (SMART-HF) will involve the application of the Smart-HF app. Smart-HF provides patients a home-based heart failure care program which is linked to a clinician portal for creation of care plans and surveillance. The clinician-created care plan will identify goals for behaviour change such as increasing physical activity, as well as observations of symptoms of heart failure, such as rapid weight gain. Symptom observations are to be input into the Smart-HF app daily and based on this intensified home surveillance, the site co-ordinator (Heart Failure nurse) may arrange review of the patient at the rapid access clinic. Other patient reported outcome measures, including the Kansas City Cardiomyopathy Questionnaire are required at 30- and 90-days and 12 months. Smart HF also includes access to educational content on heart failure (self-)management. The linked clinician portal will be used to assess or monitor adherence or fidelity to the intervention.
The Smart-HF software, supported by smartphones or tablets, IOS and android software, delivers educational information, goal-settings, homework tasks, self-monitoring and questionnaires for heart failure, to allow patient progress and outcomes to be measured. Primary endpoint is quality of life at 30 days. Secondary outcomes include hospital readmission at 30 and 90 days post hospital discharge and 90-day composite outcome of days alive and out of hospital.

Comparator / control treatment
Usual care defined as the routine care received by patients for the treatment of heart failure. In this instance, routine care consists of a multidisciplinary heart failure disease management program that comprises either home visits and/or telemonitoring or telephone support to support the patient during their transition from discharge from hospital back into the community.

Statistical methods / analysis
The statistics analyses will be performed using standard software STATA 15 (Statacorp, College Station, Texas, USA). Analysis will be based upon intention to treat. Quality of life using the KCCQ will be compared with a t-test and Mann-Whitney test. Quality of life measures over time will be analysed using the Generalised Estimating Equations (GEE) approach. Survival analysis will be used to compare admissions and other events over 30 days. The 30-day readmission rates in each arm will be compared using a chi square test, The effect size of the guided-DMP arm will be investigated using a logistic, linear and Cox models for readmissions, QOL and survival, respectively.

Summary
Brief summary
The aim of this study is to evaluate the impact of Smart-HF (a mHealth platform) on reducing readmission to hospital and other secondary outcomes. The Smart-HF platform is an app for the patient that delivers educational information, goal-setting, homework tasks, self-monitoring and questionnaires to patients with heart failure, and allows patient progress and outcomes to be measured via a clinician portal. Participants are patients admitted to the general or cardiology wards with Acute Decompensated Heart Failure (ADHF). Enrolled patients classified with a high risk of hospital readmission and/or death - i.e., equal to or greater than median of predicted risk, 33% based on the TAS-Help study algorithm developed by CIs Marwick and Huynh - will be randomised to either usual care or Smart-HF plus usual care, with stratification by study site and type of HF (reduced or preserved ejection fraction). The primary endpoint is quality of life at 90 days post hospital discharge. Secondary endpoints - 30-day readmission, 30- and 90-day composite outcome.
