Assessment of quality of general practitioners' performances and assessment of maintaining quality requires appropriate parameters. Such are the specific protocols developed by general practice basic research. They are guiding the doctor in more than 80 difficult first consultations. When assessing the quality of a colleagues performance, we cannot give him a good mark, if he does not utilize these new tools. His eventual contendedness with a mere consulting by experience and intuition does not count. If a general practitioner on the other hand conscientiously and broadly makes use of the protocols, we can attest him: As far as possible he is offering medical care with a minimal risk of overlook rare, hidden avoidably dangerous outcomes. That is a symptom of good general practice.
