Coproduction to improve preventive health services-experiences from Germany.

Regular physical activity (PA) reduces one's risk of developing various diseases and also plays a favourable role in managing symptoms and preventing further complications. Nationally and internationally, there exist different concepts on how to increase PA in the population at large. The Friedrich-Alexander-University Erlangen-Nürnberg is currently working on a project that focuses on promoting PA in primary care. This project involves collaboration among various actors in the German healthcare system, such as healthcare insurances, representatives of physicians, patients and exercise specialists, who represent different interests and are experts in their fields of knowledge. During this process, various barriers have come to light, which yield important lessons for further studies. For example, there are differences in actors' levels of knowledge of the healthcare system and their willingness to take responsibility and initiative in the collaborative process. This article should give an impression of the joint development of exercise referral schemes, show the strengths and weaknesses and encourage exchanges of similar experiences of co-production processes.
