During the last fifty years, medicine made great progresses. Research and technologies contributed to an extraordinary development of knowledge and concepts. It might have been the best period in history for physicians to practice: laboratory tests, biochemistry, genomics, digitized imaging, public health indicators and other developments induced confidence of patients by establishing well documented diagnoses. Treatments became more efficient, with novelties, like heart transplant, chemotherapy and immuno-therapy. During this period, social security systems allowed a wider access of populations to health care. Patients were more confident in medicine and physicians felt free. Simultaneously, computer technology and information sciences developed rapidly. Data input through punched cards was replaced by PCs interconnected through networks to large computers. New softwares, data mining and knowledge bases changed the world. The World Wide Web, Internet, artificial intelligence and robotics became accessible. New hospitals using these modern technologies were planned in industrialized countries.
