[Dynamics of regionalization and repercussions of gaps in care on health marketing in remote rural municipalities].

This article analyzed the dynamics of regionalization in municipalities within hinterlands and the possible implications of gaps in care for the marketing of health. This is a multiple case study with a qualitative approach, involving 76 semi-structured interviews with municipal, regional, and state managers. The results show that, particularly in the Northern states, the regional scheme did not reflect the social dynamics of the populations and created inadequate flows and unwanted routes. The municipal political agenda often prioritized interests other than that of regionalization, and rural problems did not mobilize managers to build specific regional planning. Parliamentary amendments were essential for investment in healthcare and the managers pointed to clientelistic relationships to obtain such resources, often conditioned by political-ideological alignment. The scarcity of public services favored dependence on the private sector and the commercialization of health in different situations. The great distances and the lack of public services in municipalities in the hinterland made the local public health system offer eminently dependent on contracts with private providers who negotiated on a retail basis or via service packages. Lastly, in the wake of unmet needs and gaps in care in remote rural municipalities, players in the healthcare market ₋ companies supplying inputs, consultants, healthcare professionals, and transportation services ₋ filled the gaps in public provision, sometimes controlling prices, supply and availability of services.
