Patient participation within the German healthcare system is described at three different levels: the macro level as active patient influence on the regulation of medical care, the meso level in terms of institutions enhancing patient information and counselling, and the micro level focusing on the actual treatment decision-making process in the medical encounter. The main focus of the present publication is on the health care system-specific influences on patient participation in medical decision-making and on the current state of research and implementation of shared decision-making in Germany. We describe institutions promoting patient involvement, their aims and initiatives as well as recent changes in German legislation. Against the background of German health politics' endorsement of patient participation the German Ministry of Health funded a research consortium with shared decision-making intervention projects in various disease areas. The present state of the intervention projects' results is outlined as well as subsequently funded transfer projects and future perspectives of research grants. Supported by health politics and the utilisation of scientific evidence shared decision-making's transfer into practice is considered to be relevant to the German health care system.
