BACKGROUND: Perinatal committees evaluate deaths by medical audit to improve antenatal and neonatal care. We report data from Troms County from 1976 to 1997.
SUBJECTS AND METHODS: Antenatal, neonatal and post neonatal deaths (n=472) at > or = 20 weeks of gestation have been evaluated. Data were collected from the Medical Birth Registry of Norway and from medical records. Pregnancy risk factors, mortality rates, causes of deaths, non-optimal care and avoidable deaths were recorded.
RESULTS: The death rate (all deaths per thousand total births) declined from 13.8 (1976-80) to 7.7 (1992-97), (p<0.001), due to a reduced death rate in preterms > or = 24 weeks (p<0.001) and in those between 500 and 1995 g (p<0.001). Antenatal deaths decreased (p<0.001) due to reduced intrapartum deaths (p<0.001). Prelabor deaths, unexpected intrauterine pre-hospitalization deaths included, did not change. Postnatal deaths declined (p=0.01) due to reduced early neonatal mortality (p=0.002). Deaths from malformations (p<0.001), fetal and neonatal infections (p=0.03) and placental disorders (p<0.001) declined. Non-optimal care (22.5% of deaths, 2.3%o of total births), avoidable deaths (13.1% of deaths, 1.3% of total births), and maternal neglect (7.5% of cases with non-optimal care, 0.6% of total births) did not change. Death during transport was rare (n=5), and no deaths occurred at maternity homes. Non-cohabitance, smoking and undiagnosed SGA new borns declined, and the level of education increased in the study population.
CONCLUSION: The improvement is due to a reduction in intrapartum deaths and early neonatal mortality in preterms. A constant high rate of unexpected intrauterine deaths in non-hospitalized patients is a challenge for antenatal health care providers.
