One of the factors responsible for the creation of multidisciplinary health centres is the growth of outpatient management of multiple chronic conditions. Based on a classification of hypertensive patients into eight groups, the authors discuss the interrelations between health care organization and modification of management. They discuss the effects of modification of health care structures and the need to create new job positions for the purposes of coordination, support of patients in the form of therapeutic education and support ofyoung professionals in multidisciplinary practice. External effects are improvement of office-hospital flows, especially with the development of second-line consultant roles and improved management of patient admissions and discharges. However, to ensure sustainable changes, there must be a change of mentalities with new modalities of remuneration of private practitioners and development of the health information system.
