RESUMEN
BACKGROUND: In Brazil, hospital birth care is available to all, but there are important differences between hospitals in the public and private sectors, geographical regions and capitals/inland cities, resulting in inequalities of infant health. AIMS: To assess the hospital structure for birth care in Brazil and analyze hospital adequacy to care for newborns according to levels of risk. METHODS: Data were collected as part of a nationwide hospital-based cohort study, 'Birth in Brazil'. The hospitals were classified according to whether they had a neonatal intensive care unit and divided into two models of governance: public and private financing. Three structure domains were assessed: human resources, medications and equipment for post-natal women and newborn emergency care. Newborns were classified according to the obstetric risk. RESULTS: There are more NICUs in private hospitals and they cater mostly for low obstetric risk newborns; the public sector serves 50% of at-risk patients in hospitals without an NICU. The differences between hospital service structures according to geographic region and capital/inland cities were evident. Hospitals in less developed regions and inland cities had poorer adequacy in the three domains. CONCLUSION: The distribution of neonatal care to Brazilian infants varied between the public and private sectors. The public sector offered less complex services for newborns at risk, and infants without obstetric risk were born in facilities with an NICU, creating the possibility of unnecessary intervention, especially in the private sector.
