SUS management in interstate health regions: assessment of the government's capacity.

This study displays an assessment of SUS management in a Brazilian interstate health region. An evaluative study was conducted with levels of regional analysis and data production, combining interviews with key informants and documentary analysis. Sources and data were compared and linked to analytical categories of the Government Triangle, showing a cutout of the outcomes and the government's capacity assessment. There is a low capacity for government in interstate health regions when managers and co-management spaces are unable to influence regional political decisions, limiting themselves to normative and ratifying government strategies. Disparities in the management capacity among the border states prevent the sustainability of coordinating state decision-making goals, exposing that management strategies are not enough to institutionalize interstate regionalization. There is a predominance of low SUS governance capacity in interstate health regions, and its political pattern becomes an unclear project restricted to the ideological level. The broad documentary appreciation with the use of powerful theoretical referential are methodological contributions of this research for the political analysis of SUS management in spaces that were the least examined, such as interstate borders.
