[General medicine in the 21st century].

General medicine is the main pivot of our healthcare system. General practitioners' tasks are numerous: front line responsibility, networking coordination, long-term patient care, community medicine and also primary care research. In the framework of general medicine that has been undergoing profound change for many years, we have chosen to develop three of these facets: general practitioners' knowledge of family, psychological, social or environmental factors and their capacity to coordinate with other health workers will help them in their primary and secondary prevention and also quaternary work by sparing patients unnecessary treatment and examinations. General medicine will increasingly become a discipline, one of which specific expertise will be to manage bio-psycho-societal complexity. Multidisciplinary action will be the rule: general practitioners will no longer be able to claim they can deal with all the curative, preventive and health education tasks. And the research in general medicine is essential because general practitioners can deal with over 80% of the health problems identified by patients and because the symptoms leading to the treatment cannot only be studied by laboratory or hospital research.
