Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
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
Treatment
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.
Masking / blinding
