Regional Governance in Brazil's Unified Health System: a conceptual essay.

This article is a conceptual essay aimed at supporting analyses of the regionalization processes implemented in Brazil's Unified Health System, from the perspective of regional governance. The authors conducted a literature review in the social sciences, public administration, and critical geography, focusing on the concepts of governance, territorial governance, and regional governance in the debate on development. In dialogue with these contributions to the analysis of recent regulation and implementation of health sector regionalization in Brazil, with special reference to use of the Organizational Contract for Public Action (COAP) in the country's health regions, the article concludes that the research on governance as a modern approach to linking public policies highlights the timeliness of developing methodologies and critical reflection on the relevant national processes in Brazil for future health sector proposals, thereby pointing to a new stage in the improvement of the Unified Health System.
