Description of intervention(s) / exposure
A general practitioner delivered weight management program.The Change Program consists of a GP Handbook, Patient Workbook and a template that is to be integrated into the general practice software. The Program content is based on current Australian guidelines for the management of overweight and obesity in primary care. The program is divided into three sections: Nutrition, Physical Activity and Behavioural Interventions. The Program is flexible in its delivery to suit both the patient and GP, however the suggested appointments are: fortnightly for the first three months, then monthly if the patient is happy with their progress. The full program runs over the course of two years. This pilot study will follow each patient for a minimum of 6 months.

The Program provides both GP information and patient factsheets and worksheets in the three domains (nutrition, physical activity and behavioural supports). The information in the factsheets is based on current Australian guidelines for nutrition and physical activity. The behavioural supports are based on cognitive behavioural techniques including goal setting, self monitoring and stimulus control.

The worksheets do not all need to be done in session, but can be completed by the patient at home and aid discussion with their GP. The Program also encourages the ongoing recording of the following data: BMI, waist circumference, blood pressure, relevant biochemical profile as well as a patient well-being score.

At the completion of the Program the patient can continue to be monitored by their GP as part of the usual GP/patient relationship and ongoing care.

Adherence will be monitored via the GP - we will collect information on appointment schedules, timing and interactions with other health professionals as appropriate.

Outcomes
Primary outcome [1] 293356 0
Feasibility of "The Change Program" when implemented in general practice
This will be assessed using both quantatative and qualitative measures. Patient and GP interviews; Online web based survey tool at initiation, half way and endpoint. Quantatative measures will include appointment attendance, time in consultation, time to recruitment, withdrawal rate. Survey used is designed specifically for this study.

Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
As this is a pilot feasibility study to assess practicality and operationalisation of the program there will only be an intervention arm.
Patients will be assessed as suitability by their general practitioners and invited to participate. There will also be advertising material within the general practice to encourage patients to self-nominate.

Summary
Brief summary
Our research team has developed a GP-delivered weight management program for adults in primary care based on the current Australian guidelines. "The Change Program" has already had qualitative review from both GPs and consumer representatives. It will provide GPs with practical support in managing overweight and obese adults, making the current guidelines accessible and implementable in a clinical setting.
The overarching aim of this research program is to develop an effective GP-delivered weight management program for adults that can be delivered in Australian general practice. This is a pilot implementation study to determine the feasibility for a larger scale RCT of a weight management program for overweight and obese adults in general practice. It will not have an effectiveness component at this stage. The elements of feasibility that we aim to explore include: recruitment feasibility, dropout rates, refinement of the protocol and collection of cost data, determining time processes.
The outcome of this pilot will aim to feed into a large scale, longer term, RCT to determine the effectiveness of this GP-delivered intervention.
Currently there are no GP-delivered weight management interventions in Australia and this will be a practical tool that GPs can use in their practice on a daily basis.
