Study type
Description of intervention(s) / exposure
GPs in the intervention group will receive a multi-component intervention involving continuing medical education, reminders and feedback over two years. An online module that provides continuing medical education on best practice diabetes care will be available to GPs during the two year intervention period. This module will take approximately six hours to complete and can be completed at any time over the intervention period. GPs will have access to targeted and specialist advice through the use of the Website consultant enquiry forms. Questions submitted with these forms will be answered by a endocrinologist. GPs will receive regular (at baseline and six monthly over the two year intervention) feedback on their individual perfomance and town-based comparative feedback. This feedback, based upon objective clinical measures obtained from pathology records, will be emailed to GPs.

Comparator / control treatment
Intervention towns will be compared with towns allocated to usual care that have been matched on population, remoteness, indigenous population, and socio economic index.
Control group

Primary outcome [1] 266854 0
Glycaemic control. Using the most recent HbA1c for each case within each 24 month time frame, the mean HbA1c across the town, and the proportion of all cases whose most recent HbA1c value is 7.0%, will be determined.

Secondary outcome [1] 276504 0
Blood lipids and urinary albumin control. Clinical practice guidelines recommend that blood lipids, and urinary albumin levels are tested once every 12 months as part of an annual cycle of care. Using the most recent results for each case within each 24 month time frame, the mean values of blood lipids and urinary albumin, and the proportion of all cases whose most recent values are within the relevant target ranges will be determined

Secondary outcome [2] 276505 0
Frequency of HbA1c testing.The data from the laboratory will provide the dates on which each patient had an HbA1c test. Therefore, over each 24 month period, the mean number of HbA1c tests will be determined for each patient. The proportion of cases that have had 1, 2, 3 and 4 or more HbA1c tests will also be determined for each 24 month period.

Secondary outcome [3] 276506 0
Frequency of blood lipid and urinary albumin testing. For each 24 month period (pre and post test), the mean number of blood lipid and urinary albumin excretion tests will be determined for each patient. The proportion of cases that have had 1, 2, 3 and 4 or more of each type of test will also be determined for each 24 month period.

Brief summary
To test whether population-level effects can be achieved by implementing best-evidence practice change strategies for the care and management of diabetes. The study will test whether a rural GP-focused intervention involving Continuing Medical Education (CME), reminders & feedback can:
i. Improve patterns of diabetes care as measured by frequency of testing for blood lipids, haemoglobin A1c (HbA1c) and urinary albumin
ii. Improve clinical outcomes as measured by glycaemic control, blood lipid control and urinary albumin control.
iii. Be cost-effective in terms of cost per Quality Adjusted Life Year (QALY) gained as a result of improved clinical outcomes
