Perinatal mortality in a tertiary obstetric institution.
At the Royal Women's Hospital, Melbourne in the 3 years 1987-1989 analysis of the records of 13,347 public patients revealed an overall perinatal wastage of 20.8 per 1,000 births. This seemingly high figure resulted from the fact that 45% of losses occurred in nonbooked and emergency admissions. Many patients were referred with major complications of pregnancy, especially gross prematurity, lethal congenital malformations and intrauterine deaths. During the 3-year period 74% of perinatal losses occurred before 33 weeks' gestation and only 10% were after 37 weeks. By comparison at a Victorian State level, 47% of perinatal deaths occurred before 33 weeks and more than 35% after 37 weeks' gestation. The major causes of perinatal wastage in both groups were similar. At the Royal Women's Hospital in the 3-year period lethal congenital abnormalities accounted for 19.1% of fetal wastage, premature labour, premature rupture of the membranes and cervical incompetence 16.2%, multiple pregnancy 14.7%, antepartum haemorrhage 14.0% and hypertensive disorders 9.7%. During the 3-year period 7.7% of hospital stillbirths were intrapartum compared to 27% for the State of Victoria. The stillbirth rate in Victoria has declined over the past decade, but to a lesser extent than the neonatal death rate. Over the 3-year period 1987-1989 the ratio of stillbirths to neonatal deaths was 3 to 2, and in 1989 there were nearly twice as many stillbirths as neonatal deaths (424 versus 240). Furthermore, 55% of stillborn infants in Victoria had birth-weights of more than 1,500 g compared to the Royal Women's Hospital figure of 36%.(ABSTRACT TRUNCATED AT 250 WORDS)
