This paper is based on a systematic and comprehensive review of the literature on the subject of systems’ integration, trying to provide the most relevant definitions for the understanding of the concept of integration, processes and measures that can be used as instruments of planning, application and evaluation of the integration strategies that can be easily used by politics. Seen as a natural development of the society, not as a trend imposed by policymakers, integration is achieved in particular through an institutional and spatial dynamics, which usually results in network type configurations. The paper also presents an explanation related to the field of health. The first part represents a contextualization of the integration as phenomenon, followed by conceptual clarifications, and in the last part some coordinates of the mechanism of configuration of the networks in medical care systems are presented. From methodological standpoint this article resulted from the search, selection, evaluation and summaries of some papers focused on the economy and health policy systems in the field of health
