Federative coordination and decentralization: Brazilian experience in health.

This article deals with intergovernmental relations in health within the 20 years of implantation of the Unified Health System (SUS), in the light of the historical course of Brazilian federalism and its implications to health. Initially, a theoretical-conceptual review was carried out on the topic of federalism, social welfare and federative coordination of health, considering the international debate and the historical analysis of the Brazilian case. Following, the article analyzes the federal performance in the intergovernmental coordination of national health policy during the period of implantation of SUS, based on a research about the role of the Brazilian Ministry of Health from 1990 to 2002, which involved documental analysis and interviews with federal officers and other players in national politics. It was observed that health policies registered, in the past 20 years, changes in five relevant aspects that characterize federalism: institutional arrangements and rules for decisions in the federal government; the set of players with territorial basis; legal arrangements to define responsibilities among government levels; intergovernmental tax arrangements; informal arrangements among governments - vertically and horizontally.
