Evaluation of fetal and neonatal mortality at the University Hospital of Tromsø, Norway, from 1976 to 1989
To investigate developments in perinatal care, all fetal and neonatal deaths among those born after at least 24 weeks of gestation at the University Hospital of Tromsø, Norway from 1976 to 1989, were subjected to medical audit. A decrease in total mortality rate was found when based on maturity (≥24...

To investigate developments in perinatal care, all fetal and neonatal deaths among those born after at least 24 weeks of gestation at the University Hospital of Tromsø, Norway from 1976 to 1989, were subjected to medical audit. A decrease in total mortality rate was found when based on maturity (≥24 weeks; 19.9–13.4%; p <0.01), and/or birth weight (≥500 g; 19.2–13.4%; p <0.05). This was mainly due to a decrease in fetal deaths (14.8–6.6%; p <0.0001). Deaths during labor (5.4–1.1%; p <0.001), and deaths before the onset of labour (9.4–5.5%; p <0.05) declined. The neonatal death rate remained virtually constant (5.2–6.8%). The incidence of conditions affecting the placenta and the umbilical cord, causing asphyxia and intra‐uterine growth retardation, declined, from 9.2 to 5.0% ( p <0.01), as did that caused by immaturity (2.8–1.3%; p <0.05).
