The researchers Ana Luiza D\u2019\u00c1vila Viana (University of S\u00e3o Paulo),\u00a0Guilherme Arantes Mello and\u00a0Marcelo Demarzo (both from the Federal University of S\u00e3o Paulo)\u00a0believe that the revision of such concept will allow to embrace larger productive possibilities. At the interface between studies of the historicity of the concepts and extensive fieldwork, it is argued that the traditional concept of the regionalization of the\u00a0SUS has reached the historical limits of its productive capacity.<\/p>\n

According to the researchers,\u00a0the updating of the concept of regionalization challenges innovative perspectives for a clinical system integrated in complex networks with new processes, instruments, clinical models, among others. The updated concept is part of an intersectoral conception that not only contributes towards promoting equitable and effective health care models, but also indicates the boundless inductive potential of the SUS in the development of intelligence networks and wide-ranging urban and regional development.<\/p>\n
Paradoxically, this new conception helps diminish \u2013 or rationalize \u2013 the scale of organization and planning of the system, in that it enables the regional network to be sized as the smallest unit of systemic complexity in the SUS.<\/p>\n
