Study type
Description of intervention(s) / exposure
This intervention is based on a novel concept which incorporates the principle of General Practitioners (GPs) with special interests around a multidisciplinary and coordinated approach to diabetes care in the community. This model of care includes a specialist doctor (endocrinologist), who acts in a consulting capacity to the GP, to endorse the GPs patient management plan. The intervention is delivered face to face with their advanced GP as well as with a diabetes nurse educator. This intervention will include follow up appointments which will be approximately every 6 weeks and will continue until 12 months.

Comparator / control treatment
Usual care for patients with complex type 2 diabetes is in an endocrinology and diabetes outpatients settings at a secondary or tertiary hospital. Typically patient care is delivered prodominantly by a consultant doctor (an endocrinologist).

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The person who determines if a patient is eligible to participate is unaware of the allocation group at the time of enrolment. Randomisation to group is conducted after eligibility is confirmed and consent has been provided from the patient.

Allocation to treatment group is done off site by the study statistician who is removed from the screening of participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will use a weighted control of 2 intervention to 1 control. The randomisation will be done via web based computer randomisation, which is set up by the study statistician remotely.

Brief summary
Diabetes is a chronic disease where the primary care physician has a central role to play. Historically, evidence has supported the role of diabetes teams in hospital settings being able to provide better care compared with primary care but it has been argued whether this relates to improved systematic and organised care, compared to increased expert knowledge. With appropriate support and recall systems, delivery of diabetes care in general practice can be as good as hospital outpatient care. Recognising this, the United Kingdom has seen the introduction of diabetes clinics conducted by general practitioners with special interests (GPSIs) with demonstrated favourable improvements in HbA1c, cholesterol and blood pressure. To date, Australia has not adopted GPSIs into clinical practice. However, the Australian health care system is facing significant reform aimed at shifting the focus from tertiary and secondary hospital health care to primary health care, including the move towards GP superclinics.

This research project focusses on the care of patients with complex T2DM who have been referred by their GPs for specialist diabetes care. This research is based on a novel concept which incorporates the principle of GPs with special interests around a multidisciplinary and coordinated approach to diabetes care in the community. Important to this model is the role of the specialist Endocrinologist in a consulting capacity to review and endorse the advanced skill GPs (GP Clinical Fellows) management plan. Few studies have investigated the staged devolution of diabetes services from secondary/tertiary care to primary care through increasing the capacity of primary care to meet the needs of patients who would otherwise use hospital outpatient services.
