[Evidence and evaluation in health promotion and prevention: the example of the health promotion initiative "healthy living in Bavaria"].

Background: The use of evidence and evaluation is rapidly gaining importance in the field of health promotion and prevention. The evidence base, evaluation methods as well as the capacity and required competencies among practitioners are still being developed.

Aims: Beyond its specific health-related targets, the health promotion initiative "Healthy Living in Bavaria" aims to integrate the use of evidence and evaluation as key components into project funding as part of a total quality management concept. Another objective is the creation of new evidence for the field of health promotion and prevention.

Approach: A core element of the quality management concept is the initiative's multistage evidence and evaluation model which embraces the initiative as a whole as well as the individual projects. The model is operationalized through a set of matching instruments for application, reporting, evaluation, and appraisal.

Conclusion: Nationally as well as internationally, evidence and evaluation stand out as central aspects of quality improvement instruments in health promotion and prevention. Characteristic of Bavaria's quality improvement approach is the seamless process from the application to the evaluation under consideration of scientific as well as pragmatic aspects.
