Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There are 2 levels of the intervention: the patient level and the general practice level.

Patient level intervention: The Inala Chronic Disease Management Service (ICDMS) provides multidisciplinary, coordinated and comprehensive care appropriate to the needs of the individual patient based on a systematic assessment of glycaemic control, presence of recognised complications of T2DM, and lifestyle and behavioural considerations. Patients will attend the ICDMS for management of acute complications of T2DM. Once blood sugar levels and/or other complications have stabilised, the patient will be discharged back to their usual General Practitioner (GP). Patients will be followed up for 12 months for the ICDMS evaluation.

General practice / primary care level – an education and training program for GPs and general practice nurses.

The education and training program for GPs consists of a number of different, inter-related activities, and will continue for at least 12 months. Participation in any of the activities will enable the GPs to gain Professional Development points in the Royal Australian College of General Practitioners (RACGP) Quality Assurance and Continuing Professional Development (QA&CPD) program.

One activity are the monthly, one hour Case Based Discussions. The program for these discussions is relatively informal, and is adapted according to the needs of the attending GPs, the patients seen at the ICDMS, and any "hot topics" in diabetes care.

GPs can also participate in the more formal, eight week "clinical fellow" training. Each session is 1.5 hours. The clinical fellow training aims to provide GPs with advanced skills, knowledge and confidence in caring for patients with T2DM who have complex care needs eg. a number of co-morbidities.

GPs will also be able to undertake supervised clinical attachments. These will consist of observing an endocrinologist over 10 hours of consultation time, and keeping a reflective diary of the experience.

The practice nurse education and training program will consist of a series (approximately 3) of 2 hour seminars that are aimed at enabling the practice nurse take a more active role in providing comprehensive, coordinated care for patients with T2DM.

Other design features
The patient level intervention is an open controlled trial. A geographical control is being used to assess the impact of the intervention on a range of clinical and patient related outcomes (listed previously).

The general practice intervention is a clustered randomised control trial, only involving general practices from the intervention area who have patients receiving care at the ICDMS. General practices were stratified according to the number of GPs, and randomised to either immediate or waitlisted participation in the GP and practice nurse education program. Practices were divided into two strata (one or two GPs, and three or more GPs), coded, and randomly allocated to the two groups by a blinded assessor, using opaque sealed envelopes. The impact of this intervention will be assessed by reviewing processes of care within the general practice of non-referred patients.
