The role of a maternity waiting area (MWA) in reducing maternal mortality and stillbirths in high-risk women in rural Ethiopia.

摘要

OBJECTIVE: To describe maternal mortality and stillbirth rates among women admitted via a maternity waiting area (MWA) and women admitted directly to the same hospital (non-MWA) over a 22-year period. DESIGN: Retrospective cohort study. SETTING: Hospital in rural Ethiopia, which provided comprehensive emergency obstetric care and has an established MWA. POPULATION: All women admitted for delivery between 1987 and 2008. METHODS: Data on maternal deaths, stillbirths, caesarean section and uterine rupture were abstracted from routine hospital records. Sociodemographic characteristics, antenatal care and other data were collected for 2008 only. Rates and 95% confidence intervals were calculated for maternal mortality and stillbirth. MAIN OUTCOME MEASURES: Maternal mortality and stillbirth. RESULTS: There were 24, 148 deliveries over the study period, 6805 admitted via MWA and 17, 343 admitted directly. Maternal mortality was 89.9 per 100, 000 live births (95% CI, 41.1-195.2) for MWA women and 1333.1 per 100, 000 live births (95% CI, 1156.2-1536.7) for non-MWA women; stillbirth rates were 17.6 per 1000 births (95% CI, 14.8-21.0) and 191.2 per 1000 births (95% CI, 185.4-197.1), respectively; 38.5% of MWA women were delivered by caesarean section compared with 20.3% of non-MWA women, and none had uterine rupture, compared with 5.8% in the non-MWA group. For the 1714 women admitted in 2008, relatively small differences in sociodemographic characteristics, distance and antenatal care uptake were found between groups. CONCLUSIONS: Maternal mortality and stillbirth rates were substantially lower in women admitted via MWA. It is likely that at least part of this difference is accounted for by the timely and appropriate obstetric management of women using this facility.
