Neonatal mortality has gained relevance in public health given the reduction of the postneonatal mortality rate and its impact in the infant mortality rate. Thus, deaths within the hospital began to account for the largest proportion of infant deaths. Some characteristics of mothers and newborn contribute to the increased risk of neonatal death and to demand more complexity of hospital care. This research aims to analyze the evolution of early neonatal mortality in the metropolitan areas of São Paulo (RMSP) and Santos (RMBS), according to the complexity and characteristics of hospital care of newborns in the period 2006-2009. The RMSP is the most developed region of São Paulo and has intermediate levels of infant mortality, since the RMBS, despite being one of the richest regions, records the highest rate in the state. This is a study based on secondary data (SIM, SINASC and CNES), which will use the technique of deterministic linkage for linking these databases. Variables will be analyzed the characteristics of hospitals in relation to care delivery and the newborn, and the profile of the mother and neonate. Cluster and factorial analysis will be used to generate the complexity typology of hospitals. Data will be analyzed by hospital complexity and their link with the SUS. Analysis of mortality, are calculated the early neonatal mortality rate, total and by birth weight, and relative risk. The present study therefore aims to contribute to the improvement of quality care to delivery and newborns, with subsidies to reduce infant mortality in São Paulo. (AU)
