[Report from an ongoing research project: The Cologne Research and Development Network (CoRe-Net) and the value-based approach to healthcare].

With the BMBF's funding program "Structural Development in Health Services Research" the Cologne Research and Development Network CoRe-Net is being set up by various partners from both clinical practice and health services research. The network focuses on the further development of healthcare according to the concept of learning organizations. On the basis of three research projects, the Cologne network CoRe-Net aims to establish itself in a sustainable manner and analyze healthcare delivery for two vulnerable patient groups. The two groups include a) deceased patients in Cologne and b) people suffering from heart disease and an associated mental comorbidity. The Cologne network CoRe-Net is based on M.E. Porter's value-based healthcare approach.
