Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will be delivered by telehealth between specialists in a metropolitan health service and health professionals in a regional health service
1) One appointment of one hour telehealth review by a heart failure (HF) Cardiologist (from a metropolitan hospital) with the patient and their regional site Dr/GP by day 10 post-discharge, and 2) five appointments each of one hour telehealth reviews by a HF nurse practitioner from a metropolitan hospital, in conjunction with the regional site community outreach nurse and patient by day five and then weekly for 28 days post-discharge
The purpose of the review by the HF Cardiologist is to review the HF patients post-discharge and to develop a management plan with the patient and their local Dr/GP.
The purpose of the review by the HF nurse practitioner is to prescribe and titrate medications and provide education about HF based on the Heart Foundation HF patient resource.
The telehealth review protocol is designed specifically for this study
No training is required by the cardiologist and nurse practitioner as both are qualified and experts in the field. Each telehealth consultation will collect data about the treatment and management plans implemented during the consultations. These consultations will not be recorded.

Comparator / control treatment
The stepped wedge randomised controlled trial will require randomisation to the intervention of two health services at a time each for a duration of nine months.
The control group will receive usual care which is no review or telehealth review with a cardiologist or heart failure nurse practitioner. Follow up post discharge will be as organised by hospital staff.
Control group
Active

Outcomes
Primary outcome [1] 328650 0
Composite outcome of all-cause rehospitalisations and all-cause mortality at 12 months from the time of discharge. This will be collected by data linkage with hospital medical records
Timepoint [1] 328650 0
12 months post-discharge
Secondary outcome [1] 399829 0
The patient received a telehealth visit from a HF nurse practitioner with the local community outreach service within five days of discharge. This will be collected during the telehealth visit
Timepoint [1] 399829 0
5 days post-discharge
Secondary outcome [2] 399830 0
The patient received a telehealth visit from a Cardiologist within 10 days of discharge. This will be collected during the telehealth visit
Timepoint [2] 399830 0
10 days post-discharge
Secondary outcome [3] 400826 0
Composite outcome if the patient was prescribed, when medically indicated, beta-blockers, angiotensin converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), or angiotensin receptor neprilysin inhibitors (ARNIs); and mineralocorticoid receptor antagonists (MRAs). This will be collected from medical records and telehealth clinic notes.
Timepoint [3] 400826 0
30 days post-discharge

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software.
Allocation was stratified based on the size of the health service. At each step one large and one small health service were randomised. Sites were randomised to sequence of implementation in step 1, 2, or 3.
Masking / blinding

Other design features
This is a stepped wedge cluster randomised trial. The unit of randomisation is the health service

Not Applicable
Type of endpoint/s
Statistical methods / analysis
These will be conducted on an intention-to-treat basis. A generalized estimating equation approach, logit link and binomial distribution, will be used to compare the primary and secondary outcomes between intervention and usual care periods. The covariance matrix will account for clustering induced by the sites and by patients contributing with multiple admissions. A biostatistician is responsible for the statistical analysis
