OBJECTIVE. Type 2 diabetes can be efficiently prevented by lifestyle intervention provided for people at high diabetes risk. The aim of this paper was to conduct a literature search on existing quality indicators for type 2 diabetes prevention and to collate and present a set of indicators that could be applied in European countries with different health care systems and cultures. METHODS. Scientific and grey literature was searched for relevant studies using electronic databases. We also hand searched previous systematic reviews and reference lists of relevant articles. RESULTS. The only publication identified was the report presenting the results from the IMAGE project. The IMAGE indicators were used as the basis for the proposed indicators. CONCLUSIONS. Publications on quality indicators of diabetes prevention programmes are scarce. The quality indicators presented here are a first step toward the definition of a core set of European indicators to monitor and improve the quality of diabetes prevention.
