Diabetes Prevention in Australia: 10 Years Results and Experience.

Clinical trials have demonstrated the efficacy of lifestyle modification for the prevention of type 2 diabetes mellitus but it was achieved at higher cost than can be sustained in routine health services. The first clinical trial to report was the Finnish Diabetes Prevention Study. This paper describes how Australia worked with Finnish colleagues to adapt the findings of that study to achieve a statewide diabetes prevention program. Small evaluative, effectiveness trials have been conducted in a number of countries to see if the results of the clinical trials can be replicated in routine health services. The Australian evaluative trial, Greater Green Triangle Diabetes Prevention Program is described in detail to demonstrate the ingredients for success in moving a program from one country to another. Few countries have managed to scale up from evaluative trials to statewide or national programs. The Australian experience is described in detail including lessons learned about what reduced the effectiveness, particularly the need for policy makers in government, people from the implementing organisation and researchers to work together from the start of the evaluative trial and throughout the first 5 years of a national program.
