Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants enrolling in the project will attend a briefing session. The briefing session will be a facilitated learning session based around self-management and behaviour change carried out using the Self-Determination Theory (SDT) framework. This theory is used to support, educate and motivate participants around positive lifestyle choices, as well as the empowerment of individuals over their health care. SDT has been chosen as the framework in which to deliver the briefing session as has been shown to complement MI and CBT integration. The briefing session will be delivered face-to-face in a group setting, with up to 9 participants to a group. The session will last for approximately 45 minutes.

The intervention group will receive the blend of Motivational Interviewing (MI) and Cognitive Behaviour Therapy (CBT) delivered over the telephone. Each participant will receive 5 calls over a 12-week period, each lasting up to 20 minutes. Participants will receive 4 calls in the first 6 weeks, and a booster call at 12 weeks. In terms of incorporating MI and CBT, MI will be utilised for sessions 1 to 3. From session 3 to session 5 a blend of MI/CBT will be used. The intervention will begin for participants one week after they have attended the briefing session.

Both the briefing sessions and the MI-CBT intervention will be delivered by an Australian Health Practitioner Regulating Authority (APHRA) registered physiotherapist. He has attended a 2-day workshop on MI and will receive additional coaching from a nationally endorsed Health Psychologist and Sport and Exercise Psychologist.

As part of self-management support, participants, where the intervention is appropriate, may be referred into community programs aimed at lifestyle risk modification. Following the MI/CBT theory, no mandatory referrals will be made to these programs, however the facilitator may highlight the existence of these programs should the situation warrant it. The facilitator will be aware of the programs that are available in the community and can make appropriate consented referrals to the programs on behalf of the participants.

For measurement of fidelity, 10% of counselling sessions in the study will be digitally recorded. The recorded sessions will be assessed for adherence to MI-CBT principles using the MI-CBT fidelity scale and coded by an expert independent coding group.

Comparator / control treatment
The comparator for the H4U-2 project is termed the minimal intervention arm of the project.

All participants of the minimal intervention group are required to attend the briefing session. As described above, the briefing session will be a facilitated learning session based around self-management and behaviour change carried out using the Self-Determination Theory (SDT) framework. This theory is used to support, educate and motivate participants around positive lifestyle choices, as well as the empowerment of individuals over their health care.

Participants in the minimal intervention group will receive no further behaviour change support from the research team.

Body mass index (BMI).
Body mass will be recorded to the nearest 0.1 kg using a calibrated scale (model 813; Seca, Germany). Free standing stature will recorded to the nearest 0.1 cm using a calibrated equipment with the participant barefoot (Portable stadiometer; Seca, Germany). BMI will be calculated by dividing body mass by the square of height.

Secondary outcome [4] 353593 0
Cost-effectiveness of the program determined by an economic analysis.
Cost effectiveness of the intervention will be evaluated from a health system perspective. Data for resource use associated with the intervention will be calculated, as well as costs derived from hospital admissions. Quality of life measured using SF-12 at baseline, 13 weeks and 9 months will allow calculation of differences in Quality Adjusted Life Years (QALYs) between groups.

We will calculate the cost per QALY for each treatment comparison as the difference in mean costs divided by the difference in mean outcomes over the duration of the trial.

Eligibility
Key inclusion criteria
All participants will be recruited from an elective non-admitted outpatient clinic in Bendigo Health; only non-admitted patients are eligible for participation in this study.

Study participants will be required to be fluent in conversational English, and to self-report as insufficiently physically active (not participating thirty minutes or more of moderate physical activity on at least five days a week; 150 mins/week).

Interested participants will be required to complete a Physical Activity Readiness Questionnaire (PAR-Q). The PAR-Q offers a safe preliminary screening of candidates for exercise testing and prescription. If a participant answers ‘yes’ to one or more questions then they will be required to speak to their doctor regarding the intervention, and the amount of physical activity that they should perform. Clearance to participate from their doctor must be presented to the research team. The use of the PAR-Q as a screening tool is part of duty of care to the participants. The PAR-Q must be completed before any participant attends a briefing session
Minimum age

Maximum age

Can healthy volunteers participate?
No
Key exclusion criteria
The following exclusion criteria will apply: under 18 years and over 69 years; poor comprehension of English language; too physically active (participating in more than thirty minutes of moderate physical activity on at least five days a week); deaf/hearing impaired; disabling neurological disorder; severe mental illness such as psychosis, learning disability, dementia and cognitive impairment; registered blind; housebound or resident in nursing home; unable to move about independently or not ambulatory; pregnancy; advanced cancer.

Patients who are categorised as a Category 1 in the hospital surgical wait-list may expect to undergo their surgical procedure within thirty days. For this reason individuals categorised as a Category 1 in the hospital surgical wait-list will be excluded.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation: Participants will be randomised to the intervention or the control group using a concealed allocation, block randomisation method with 1:1 allocation. Participants will be randomised using a web-based program (randomization.com) with assignments sealed in sequentially numbered opaque envelopes.
Only after the recruiter determines a participant is eligible, the participant agrees to take part (provided written informed consent) and baseline assessment is completed, will assignment to group be made by opening the next envelope in the sequence
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence generation will be generated from a web-based program (randomization.com).

Statistical methods / analysis
To compare differences in our outcome measures a series of 3 x 2 mixed model ANOVAs will be undertaken. Utilizing data from the H4U study [Barrett et al, 2018; 18:1166], to detect an effect size of 0.35 or greater, with the alpha set at .05, and the power set at .90, a sample size of 50 participants per arm will be required. Protecting against a drop-out rate of 20% over the 9 month period, 60 participants will be recruited and randomized into each arm. The total study sample will therefore be 120.

Summary
Brief summary
Chronic are the leading cause of illness, disability and death in Australia. Hospitals, as a result, need to broaden their role from disease treatment towards a position of more preventive care.

This study will examine if telephone coaching can increase physical activity and health outcomes from non-admitted hospital patients coming to see a surgeon. Telephone coaching can support and motivate participants through a range of strategies for health-related behaviour change. This office based intervention may also create linkages between hospital patient’s and programs available in the community.

It is hypothesised that by the end of the intervention, compared to the minimal intervention group, the participants in the intervention group will show significant improvements in physical activity, and in physical activity self-efficacy, quality of life, and anthropometric values.
