`titrebPhysicians as partners of the State to promote primary care teams’ coordination: Between instrumentation and professionalization`/titrebIn France, the increase of the number of the Multidisciplinary group practices within the community has been a major policy objective in recent years.

In 2014, a coalition of key actors was formed to conceive a special training`np pagenum="034"/b program called Pacte. It was dedicated to Primary care team coordinators and implemented in six Regional Health Authorities.
