Study hypothesis
In general practices receiving glycaemic educational messages attached to laboratory test reports, compared to those practices not, the number of HbA1c test requests will be higher and the mean HbA1c value will be lower. Similarly for cholesterol messages the number of cholesterol tests will be higher and the mean cholesterol value will be lower.

Diabetes mellitus
Intervention
Short educational messages added to paper and electronic general practice laboratory test reports of Haemoglobin A1c (HbA1c).
Practices, stratified by list size, will be randomly allocated to each intervention (glycaemic control educational messages and cholesterol control educational messages) independently. In the first randomisation, practices will be allocated to receive the glycaemic educational messages or control (no glycaemic educational messages). In the second randomisation, practices will be allocated to receive the cholesterol educational messages or control (no cholesterol educational messages). This will result in four groups:
1. Practices receiving glycaemic and cholesterol educational messages
2. Practices receiving only glycaemic educational messages
3. Practices receiving only cholesterol educational messages
4. Practices receiving no educational messages
This will allow comparisons of the separate and combined effects of the two educational message interventions.
