BACKGROUND: Quality assessment of perinatal care can be carried out by classifying perinatal deaths. In the following we have analyzed the geographical contrasts in perinatal deaths according to the Nordic-Baltic perinatal death classification in a sparsely populated Norwegian county. MATERIAL AND METHODS: All stillbirths (> or =28 weeks of gestation) and neonatal deaths (gestational age > or =22 weeks; death < or =28 days) in 1986-96 from Nordland county (240,000 inhabitants) were classified. For comparison the county was geographically divided into six general local hospital areas and one central hospital area. RESULTS: The classification showed a well acceptable inter and intra observer variation. One hundred and seventy-one stillbirths and 155 neonatal deaths were analyzed. The death rate (pr 1,000 births) for single, non-malformed, antenatal stillbirths was higher in the central hospital area than in the local hospital areas (3.22 vs. 2.02). The death rate for extreme preterm infants (22-27 weeks of gestation) was on the other hand higher in the local hospital areas (2.45 vs. 1.05). One of the general local hospital areas was singled out with an especially high neonatal death rate among extreme preterm infants. This was to some extent explained by the death of extreme preterm twins and triplets. CONCLUSION: The Nordic-Baltic perinatal death classification system is a consistent and reproducible tool also for studying perinatal death in restricted geographical areas. The observed contrasts in perinatal deaths were used as basis for programs aimed at improving perinatal care. The observation of an unexplained increased number of antenatal stillbirths in the central hospital area resulted in a program for prospective recording and better characterization of the placenta and umbilical cord. Proposals for a better antenatal program preventing extreme preterm birth of twins for the whole county has been launched. In utero transfer to a hospital with a neonatal intensive care unit seems crucial in improving the prognosis for these infants.
