title: Higher perinatal mortality in National Public Health System hospitals in Belo Horizonte, Brazil, 1999: a compositional or contextual effect?
abstract: OBJECTIVE
  In Brazil, it was previously reported that in hospital perinatal, neonatal and infant mortality rates are higher for hospitals contracted to the National Public Health System (SUS) compared with non-SUS hospitals. We analyse whether this reflects a compositional effect (selection of patients) or a contextual effect.
  
  
  METHODS
  Population-based cohort study.
  
  
  METHODS
  Belo Horizonte, Brazil, 1999.
  
  
  METHODS
  A total of 36,469 births in 24 hospitals.
  
  
  METHODS
  A multilevel analysis was carried out using information gathered at the individual level on maternal education (used as an indicator of socio-economic status), maternal age, type of pregnancy and delivery, birthweight and sex of the fetus.
  
  
  METHODS
  Perinatal death.
  
  
  RESULTS
  Risk factors for perinatal death included male sex (OR = 1.25; 95% CI 1.01-1.55), birthweight of 1500-2500 g (OR = 7.65; 95% CI 5.74-10.20), birthweight of 500-1500 g (OR = 187.54; 95% CI 141.31-248.39), less than 4 years of maternal education (OR = 2.93; 95% CI 1.68-5.10), as well as birth at private-SUS (OR = 2.92; 95% CI 1.87-4.54) or philanthropic-SUS hospitals (OR = 1.81; 95% CI 1.12-2.92). After controlling for individual characteristics, there was still a significant variation in perinatal deaths between hospitals categories.
  
  
  CONCLUSIONS
  Independent of compositional (or individual) characteristics, hospital factors exert an influence on the risk of perinatal death, primarily hospital category related to SUS. Considering the highest proportion of births in SUS hospitals in Brazil, especially private-SUS hospitals, improving hospital quality of care is an urgent priority for reducing the toll of perinatal and infant mortality, as well as inequalities in these outcomes.
