[Formation of centers in general and abdominal surgery -- necessity or trend?]. / Zentrenbildung in der Allgemein- und Viszeralchirurgie - Notwendigkeit oder Trend?

The introduction of the DRG (diagnosis-related groups) system as basis for reimbursement in the German health-care system has led to a mentality of quality orientation and verification of therapeutic results. An immediate result was the formation of medical "centres" on rather different levels and consequently the inauguration of institutions, authorities, and organisations to review these centres. Finally, a range of certifications was installed in order to stratify the rather diverse aims of different centres. This review critically evaluates the current situation in the field of general and abdominal surgery in Germany.
