Public health management: systemic analysis of social determinants of health in Brazilian municipalities

The health sector is considered extremely important by governments and multilateral international organisms, due to its implication to life, as well as material and human struggling involved. This study adopts a systematical approach in order to question if the mortality outcomes in medium Brazilian cities explain or may be explained by factors considered external to the public health service, expressed by health social determinants. Therefore, this study aims to investigate health conditions in public health management in medium Brazilian cities. The scenario adopted contains 192 cities with a population contingent between 100 000 and 500 000 inhabitants, between the years 2007 and 2011. The database produced, containing 30 indicators representing conceptual models referenced, allowed the elaboration of an operational model of health social determinants from a Bayesian network. As result, we elaborated a model of health system formed by six factors, showing associations that allow a better comprehension about relations among health social determinants and health conditions, producing contextualized information, able to subsidize the formulation of strategies by managers of Sistema unico de Saude.
