Interventional
Description of intervention(s) / exposure
Six sites across Australia will gain access to IBIS-Survivorship model of care to be rolled out every 4 months.

At completion of treatment [i.e., end of surgery, or adjuvant chemotherapy/ radiation therapy (whichever was delivered last)], patients will be enrolled in the study. If the site has been randomised to commence the intervention then participants will receive the IBIS-Survivorship model of care:

1 x 30-60 minute face-to-face or telehealth Specialist Cancer Nurse consult with the participant 8+/-2 weeks post-treatment to: 1) provide treatment summary; 2) provide survivorship patient education including a written survivorship booklet on “Living Well After Cancer” published by Cancer Council Australia; 3) co-develop a draft Survivorship Care Plan (SCP) including SMART goals (using motivational interviewing and self-efficacy techniques); and 4) provide a draft post-treatment shared-care follow-up appointment schedule. A draft SCP (including the treatment summary) will be provided to the participant via email or post and their nominated GP via GP clinic preferred communication system. Adherence to the nurse-led clinic and it's components will be monitored using a nurse-led clinic checklist.

1 x 20-30 minute video/telephone case-conference between the Specialist Cancer Nurse and GP (+/- GP practice nurse) within 4 weeks of Specialist Cancer Nurse consult to finalise the SCP and negotiate the GP’s role in facilitating SCP SMART goals as well as seek agreement on the post-treatment shared-care follow-up appointment schedule. Adherence to the GP case conference and it's components will be monitored using a GP case conference checklist.

Up to 11 (depending on how far post-diagnosis the patient is when they enter the study) alternating 6-monthly face to face or telehealth (as per clinician) patient appointments with cancer specialist or GP for 5 years. At 5 years the patient will be discharged to the care of the GP.

More specifically:
5 x GP appointments at <12- (initial), 18-, 30-, 42- and 54- months post-diagnosis for review of SCP, general health, screening/management of comorbidities, psychosocial health cancer treatment toxicities, cancer-related symptoms, chronic disease management planning, allied health referrals and physical examinations (if required/agreed). The GP appointments duration will vary depending on participant need. Additional appointments with the GP can be scheduled if clinically indicated. The GP will have direct telephone access to the Specialist Cancer Nurse in case of concerns or escalation for acute care review. Adherence to the minimum GP appointment schedule will be monitored using MBS data.

6 x cancer specialist appointments at 12-, 18-, 24-, 36-, 48- and 60-months post-diagnosis for review, physical examination, and imaging (i.e., annual mammogram). The cancer specialist appointments duration will vary depending on participant need. Additional appointments with the cancer specialists can be scheduled if clinically indicated. Adherence to the minimum specialist appointment schedule will be monitored by checking medical records and hospital appointment scheduling data.

Behaviour
Comparator / control treatment
At completion of treatment [i.e., end of surgery, or adjuvant chemotherapy/ radiation therapy (whichever was delivered last)], patients will be enrolled in the study. If the site has not yet been randomised to commence the intervention, then participants will receive standard follow-up care plus a written survivorship booklet on “Living Well After Cancer” published by Cancer Council Australia. The current follow-up arrangement is a specialist-led model as determined by the treating surgeons, medical oncologist, and radiation oncologist. Follow-up care will be offered up to 5 years post-diagnosis.

Intervention assignment
Crossover
Other design features
This study is a multi-centre, prospective, pragmatic, stepped-wedge cluster-RCT design. The trial design involves the sequential rollout of IBIS-Survivorship to each of the clusters (in this case, cancer centres) in a randomly allocated order within the study period, with clusters progressively “crossing over” eveyr 3 months from the control group (usual care: specialist-led model) to the intervention group (receiving IBIS-Survivorship). The sites are blinded to the randomisation order until 2 months prior to the site rolling over to IBIS-Survivorship.

Type of endpoint/s
Efficacy
Statistical methods / analysis
Generalised linear mixed models with fixed categorical effects for time; random cluster and random cluster by time effects will be used to test the difference between groups for FACT-B scores at 12 months (H1). Random cluster by time interactions will be included to allow for correlations within clusters to decay with increasing separation between times of measurement of observations. Similar analyses will be conducted for secondary outcomes (H2), applicable to the data type. Results will be presented as means or odds ratios with 95% confidence intervals. Analysis will be conducted as intention to treat and sites will be considered exposed to the intervention post-randomised cross-over date. We will also monitor the characteristics (i.e. cancer stage, hormone receptor status, age, presence of other chronic conditions, highest educational qualification, and Socio-Economic Indexes for Areas) of patients recruited both pre- and post-crossover and adjust for any differences at the analysis stage.

Economic Appraisal: We will extend methods of a standard cost-effectiveness analysis, which compare the costs and patient wellbeing associated with the intervention versus usual care, by incorporating a societal perspective. This is important in order to capture the higher complexity involved in shared-care models. Intermediate outcomes (e.g., uptake, satisfaction) will be incorporated and interactions between Specialist Cancer Nurses, GPs and patients modelled. We will assess budget impact analysis, cost-effectiveness and model longer-term predicted outcomes based on real-world evidence synthesis. Specialist Cancer Nurse costs to carry out and deliver the intervention (time and salary)
The economic evaluation, modelling and budget impact analysis will conform to international best practice methods. The benefits of IBIS-Survivorship will include intermediate outcomes which link to patient well-being (e.g. % GP adoption influencing cost-savings, symptom improvement leading to earlier return to work). Incremental cost per effect ratios will be generated which represent the additional cost and benefits (QALYs) of the intervention over and above that of usual care. Costs will be aggregated across the groups and means/totals generated. Analyses will consider advanced modelling techniques (dynamic models, discrete event or microsimulation cohorts) handled in TreeAge Pro 2018 software. Extensive one-way and probabilistic sensitivity analyses will be performed to address uncertainty and scenario analyses.

Summary
Brief summary
The purpose of this study is to test the implementation of a care model involving hospital-based medical teams (medical, surgical and radiation oncologists) and GPs for post-treatment follow-up care for early breast cancer.

Who is it for?
You may be eligible for this study if you are aged 18 or older, and have breast cancer.

Study details
Participants in this study will be assigned into two groups. One group will receive standard follow-up (hospital-led) care and information from Cancer Council Australia. The other group will undergo the share-care model. This involves a series of 20 to 60 minute appointments with specialist nurses, GPs and hospital cancer specialists for up to 5 years.
As part of the study all participants will answer a series of questionnaires every 6 months for 12 months.

It is hoped this research will demonstrate the and effectiveness and cost-effectiveness of the new model of care which could influence future breast cancer follow-up care.
