The 21st is being recognized as the Century of the Person, particularly in Medicine and Health. Person Centered Medicine, as a concept and global programmatic movement developed in collaboration with the World Medical Association, World Health Organization, International Council of Nurses and 30 other institutions over a decade of annual Geneva Conferences, places the whole person as the center of health and as the goal and protagonist of health actions. Seeking the person at the center of medicine, has meant a medicine of the person, for the person, by the person and with the person. Articulating science and humanism, it strives for a medicine informed by evidence, experience and values and aimed at the restoration and promotion of health for all. The textbook on Person Centered Medicine reviews this perspective as it has evolved to date and its resulting knowledge base.
