Blending public health and primary care together means building bridges between professionals - those who deal with the health and care of individuals and those who deal with the health of a population. At the organizational level, many factors facilitate the integration of these two areas among which : a clear mandate with a vision, identified goals, and the development of a collaborative culture.

Elsewhere in the world, similar institutions already exist and sometimes take different forms. In this article, we will briefly present four of them in Wales, Scotland, Canada and the Netherlands.
