The article reflects on the chances of constructing a social pact, or forms of concertation. among organized actors in the health sector. in light of implementation of the Unified Health-care System [Sistema Único de Saúde] and of associated impasses. The discussion addresses theoretical aspects raised by the neocorporatist perspective regarding state/civil society relations. the associative dimensions of the social order. political exchange between the public and private realms, and the mediation of organized interests in policy-making within contemporary democracies. In an overview of the pattern of interest organization as historically structured in Brazil, the hybrid. or dual, format of representation is highlighted. By reference to a synoptic table illustrating the evolution of sectoria! associativism vis-à-vis that of health policies, an examination is made of such characteristics as representation formats [dual, trichotomic] and the density of the constellation of associations representing the interests of professions, the producers of health technology. and. in particular, the medical/health-care industry. Las-tly, given the stage of maturity and complexity of the universe under analy-sis. questions are raised as to the potential political efficaciousness of the Health Board [Conselho de Saúde] as an inDepartamento de Ciências Humanas e Saúdestrument meant to achieve struc-tural and cultural transformation within the health-care system and as to whether it is the most suitable locus for the collective concertation between the organized interests represented therein.
