Description of intervention(s) / exposure
The self-management Optimal Health Program (OHP) will utilise the Collaborative Therapy Framework delivered by a OHP facilitator. SCOHP is composed of three core components adapted to suit the specific needs of the stroke survivor and the carers. This is part of a larger program of larger research study known as the Translational Research, Integrated Public Health Outcomes and Delivery (TRIPOD).

TRIPOD is a collaborative effort between three research projects aimed at understanding the efficacy and impact OHP has on the wellbeing of people with specific chronic health problems and their carers. The study of OHP with people with type I or type II diabetes has been previously registered as a trial (ACTRN12614001085662) and as with people undergoing dialysis (ACTRN12615000810516). The pilot of SCOHP was called ACCORD and registered as a trial (ACTRN12613000064707).

a) The OHP framework utilises a modular format. Each module encompasses a manualised discrete skill development intervention run over 8 weeks (plus booster session), one hour in duration, one on one, conducted by a trained health professional, involving: health promotion, interagency collaboration, accessible support care coordinator, information about stroke and resources, understanding stress, family and community support and caring relation to stroke. The modular format allows for tailoring of the intervention to suit the needs of carers and stroke survivors at various stages of the illness. Similarity across modules in terms of the core intervention, plus overlap between modules, enhances implementation through familiarity with the methods and style. This also addresses efficiency and cost-effectiveness with respect to training staff. Each session with the ‘I Can Do model’ as the
core theme. It is one of the unique components of the OHP.

b) Self-efficacy of the carer is a pivotal part of the process and is taught using a systematic approach to both clinicians and consumers with each module, regardless of content, delivers education, coping strategies, skills development and adaptation paradigms. This supports the philosophy that a person’s illness should not be ‘dependent on’ but ‘supported by’ the services they need to utilise.

c) Smooth integration from acute through to community care is paramount. Therapeutic and systemic collaboration with consumers and clinicians will be an integral part of the process. These parties will inform both the content of the group intervention and its integration into existing service structures.

SCOHP sessions will be conducted 1 hour per week for 8 weeks. There may be some unavoidable variation depending on participant circumstances (e.g. ill health may lead to longer break between sessions). Sessions will be conducted one-to-one and sessions are facilitated by a trained OHP facilitator. A single booster session will be conducted with participants 3 months post completion of intervention. The booster session is also one hour duration and the overall theme for this session is to address 'what is my health like now' for participants. This booster session will involve review of health plans 1, 2, and 3, consolidation of progress and reflection on achievements towards health related goals.

Post-intervention focus groups, with clinicians (nurses, physicians, GP’s and mental health workers) and with consumers will be conducted to assist in the evaluation of SCOHP. The focus groups will be for two hours facilitated by two investigators exploring the views of health professionals, carers and survivors of stroke. There will be an opportunity for the investigators to report the findings of the project as well as record the opinions and experiences of the participants.

The individualised Collaborative Therapy program (SCOHP) will involve baseline, 3-month, 6-month and 12-month follow-up.

OHP facilitators will receive training, and regular weekly supervision to discuss problems and minimise non-standardised activity. In addition, thematic issues will be raised at supervision meetings. OHP facilitators will also maintain session notes and attendance records for each
participant to assist with supervision and monitoring of adherence to OHP protocol.

Comparator / control treatment
For stroke patients recruited from St. Vincent's Hospital:
Standard care as provided by the multidisciplinary neurology and rehabilitation teams at St Vincent’s Hospital.

For stroke patients recruited through community health organisations (e.g. National Stroke Foundation, Stroke Support Groups, Inner East Health):
Standard care will be assessed through participant responses on the Health Care Utilisation Questionnaire

Standard treatment for carers will include the current discharge planning that operates in the acute and subacute units of the hospital, incorporating referrals to allied health, community support and other clinically appropriate referrals. The length of treatment will vary from person to person according to the severity of their illness and treatment required. Inpatient rehabilitation is a standard treatment option for stroke survivors but not always required.

For carers the criteria is that they care for a friend or family member who's a stroke survivor for a minimum of 10 hours unpaid care per week. The stroke survivor doesn't have to live with them. Their standard care will be assessed through participant responses on the Health Care Utilisation Questionnaire.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A simple randomisation of equal number of subjects to treatment and control groups will be conducted. Patients and carers will be informed of the study by a research clinician working in conjunction with St Vincent's staff. Patients will also be recruited through community health organisations (e.g., National Stroke Foundation, Stroke Association Victoria) and provided with contact details to obtain further information about the study and ask questions.

Potential participants will be approached for consent and if agreeing to participate and meet inclusion criteria, will be randomised by computer generated number system to either treatment or control condition. Allocation will be concealed via method of central randomisation via computer. Consenting participants will be randomly assigned via block randomisation computerised sequence to be treated in either the intervention group, or the control group which will receive the Stroke and Carer Optimal Health Program (SCOHP) at the end of 12 months. The decision to assign will not be up to any clinician or researcher but rather a computer programme that will select numbers at random. The intervention group will receive the OHP comprising eight 1 hour sessions (and a booster session). For control and intervention group participants, baseline, three, six, and 12 month follow up will occur during which participants will complete a questionnaire.

CONSORT procedures will be followed: researchers completing the data analysis will be blind to intervention allocation and intention-to-treat analyses will be applied. The allocation sequence will be generated using random numbers. Patients will be randomised progressively as they are consented and complete baseline assessment.

Due to the variability of standard care, all participants will complete the Health Utilisation Questionnaire at baseline, 3, 6 and 12 month follow-up points to map key aspects of standard care at each unit of each site.

OHP facilitators will receive training, and regular supervision to discuss problems and minimise non-standard activity.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A simple randomisation of equal number of subjects to treatment and control groups will be conducted. Patients at St Vincent’s Hospital will be identified by diagnosis according to inclusion criteria and recruited over a 24-month period. After recruitment and consent to be involved in the trial the patient and carer will be randomised by computer generated number system to either the treatment or control group. Assessors and analysers of the results will be blinded to the randomisation process and will not know who is in the control or treatment group. Randomised computer generated number system to either the treatment or control group will be created.

Economic Evaluation
A full economic evaluation will occur alongside the proposed RCT. Both health outcomes and costs will be compared between groups from the perspective of the health care system. In addition to the health outcome measures, the utility measurement of quality of life of the survivor and the informal carer(s) will be assessed using AQoL-6D developed in Australia. The potential long term (life time) impact on cost and effectiveness of intervention beyond the trial period will be extrapolated using the Markov process modelling method.

Statistical Analysis
T-tests and analysis of covariance (ANCOVA) will be used to test for statistically significant difference between the treatment groups at 6 and 12 months. The control group will be used as the reference group in the ANCOVA and the p value associated with the treatment group variable will be used to determine the success of the trial. The treatment will be considered statistically significantly better than usual care if the p value is less than 0.05.The economic evaluation will use ICER (incremental Cost-Effectiveness Ratio) and will be based on the Australian Standard of acceptance.

Power was calculated to detect a medium effect size of Cohen's d = 0.50. This was chosen as a clinically meaningful effect size that may be compared with previous RCT research in the area of chronic disease management programs. Calculations assumed two primary outcomes (health related quality of life and GSES scores), four assessment points (baseline, 3-month, 6-month, and 12-month), a study-wide Type I error rate (alpha) of .05, and hence a Type II error rate (beta) of .20 (power of .80), a correlation of post-treatment scores with baseline measurements (Spearman's Rho or r) of 0.81, and a two-tailed statistical test. To detect an effect size of Cohen's d = 0.50, 53 participants in each of the control and intervention groups will be required. Allowing for up to 20% attrition, a total of 168 participants, or 42 carers and stroke survivors in control and intervention groups is required.

Summary
Brief summary
Stroke is a disease with severe consequences for the survivor and the unexpected carer. Carers experience tremendous changes and challenges from role reversal to financial struggle and subsequent increased burden, low mood, and poor overall health. In Australia, there are approximately 60,000 new strokes per year; a decrease in stroke mortality as a result of improvements in medical and surgical management mean people are living longer with the residues of stroke, and that carers increasingly face long-term burden. Eighty percent of individuals who experience stroke return home with varying degrees of neurological, behavioural and psychological symptoms. At home, they often rely on informal carers for their physical and emotional support. Previous psychosocial interventions to support informal carers of stroke survivors have shown promising results; however none have sought to integrate carer interventions with care coordination. To address this, the Stroke and Carer Optimal Health Program (SCOHP) has combined a 8-week individualised Collaborative Therapy with a booster session 1 month later. This research will assess the feasibility and cost-effectiveness of improving the mental and physical health, social connectedness and health service utilisation of the carers of stroke as well as stroke survivors. This model will be designed with the intention of being readily adapted and applied in the context of other physical and also mental diseases. The findings of this randomised control trial will investigate the impact of SCOHP on increasing carer and stroke survivor self-efficacy and quality of life.
