Perinatal outcomes at Bella Coola General Hospital: 1940 to 2001.

OBJECTIVE

To describe perinatal outcomes (mortality, weight, condition at birth) at an isolated, rural hospital.

DESIGN

A retrospective cohort study.

STUDY POPULATION: Neonates born to women beyond 20 weeks' gestation who delivered in the Bella Coola General Hospital (BCGH) between Mar. 7, 1940, and June 9, 2001, inclusive.

MAIN OUTCOME MEASURES: Information collected from the labour and delivery case room record book includes Aboriginal status, date of delivery, birth weight, newborn mortality, and newborn condition at birth.

RESULTS

There were 2373 deliveries, including 12 sets of twins. Total newborn mortality rates declined from approximately 4.7% in the 1940-1954 time period to 0.7% in the 1970-1984 time period and have remained near that level ever since. From 1940-1960 BCGH's perinatal mortality rate was higher than Canada's; it was lower than Canada's in the 1970s, higher in the 1980s and about the same for the 1990s. The condition of the vast majority (approximately 90%) of newborns was described as being "good" at birth. Approximately 5% of newborns had birth weights < 2500 g, and this has not changed much over the years. In the 1951-1962 time period Aboriginal women had a higher percentage (8%) of infants with birth weight < 2500 g compared with non-Aboriginal women (5%), but this percentage has declined over time to the point where the rate for both groups is now around 5%.

CONCLUSIONS

Women giving birth in the low technology environment of the BCGH experienced acceptable neonatal outcomes. Trends in perinatal mortality, morbidity and low-birth-weight rates mirror those recorded for Canada.
