[Critical reflexion on quality improvement and networking]

Qualitiy-control and networking are two issues of debate in modern medicine. The origin of these terms is not to be found in medicine, but rather in industry. However their naive transfer to the field of medicine causes damage. It is relatively easy to test industrial products for their quality. Dealing with meaningful medical problems is far too complex. Simple data such as blood pressure, HbA1c, etc. may be assessed. The only means of quality-control of complex medical situations and actions are ward rounds by attending physicians, case presentations at staff meetings, etc. Issues of clinical quality-control are discussed on the basis of the history of an aged couple. Furthermore a personal clinical experience illustrates how doctors create a useful network with other physicians and how they eliminate "useless" colleagues from their network. Economists should have no influence or impact whatsoever on the quality-control and networking of physicians.
