Regional and Macro-regional Dependency Index: A contribution to the SUS regionalization process

ABSTRACT

The study addresses the interdependency between health regions and macro-regions in Brazil in 2019, concerning both medium and high complexity hospitalizations. The analysis of the flows established was carried out using the Regional and Macro-regional Dependency Index, based on secondary data provided by the Hospital Information System of the Unified Health System (SUS). The results show that a significant number of health regions and macro-regions absorb medium-complexity hospitalizations in their territories, varying according to specialties. In high-complexity hospitalizations, most health regions are highly dependent, assistance concentrated in 15% of these. Among health macro-regions, the scenario is significantly heterogeneous: highly dependent on the North, Northeast and Midwest Regions, and highly resolutive in the South Region. Analyses show that the population size of health regions and macro-regions is inversely related to the regional and macro-regional dependency. The improvement of regionalization requires an organized health care network, one that takes into account territorial inequalities and diversities, interdependency and autonomy among the territories and actors involved, and inter-federative coordination, so as to provide care that is both comprehensive and equitable.
