title: Severe maternal morbidity and near misses in a regional reference hospital.
abstract: OBJECTIVE
  To investigate severe maternal morbidity/near misses in a tertiary public maternity in the state of Rio de Janeiro, using different identification criteria.
  
  
  METHODS
  This is a cross-sectional study, performed in a regional reference hospital between June and October 2009, on severe maternal morbidity/near miss cases identified from the log books of the maternity hospital and review of medical records. This study focused on women who, during pregnancy, delivery, or the postpartum period, showed no clinical symptoms compatible with the defining criteria for severe maternal morbidity/near miss of Waterstone et al, Mantel et al. and the World Health Organization (WHO).
  
  
  RESULTS
  Among the 1,544 admissions during the period studied, 89 women with severe maternal morbidity were identified, considering all criteria. The occurrence of severe maternal morbidity/near misses ranged from 81.4 to 9.4 per 1,000 live births (LB), depending on the criterion used. The mortality rate was 3.2%, reaching 23% in the WHO criteria. Only 40% of these women had more than six prenatal visits and 10% did not have any visit at all. The most common markers found were severe preeclampsia, followed by severe hemorrhage, ICU admissions, HELLP syndrome, and eclampsia. There were three maternal deaths with a MMR = 280/100.000 LB and one late death. The WHO criterion showed greater specificity, identifying more severe cases, while the Waterstone criterion was more sensitive.
  
  
  CONCLUSIONS
  The study of severe maternal morbidity/near misses in a regional reference hospital can contribute to the knowledge of this event's magnitude, as well as to identify its most frequent characteristics and clinical conditions, being essential for dealing with maternal morbidity and mortality.
