Obstetric risks and outcomes: birth centre compared with conventional labour ward.

Birth centres in Australia provide an option for women and their professional advisors when choosing the setting for childbirth. It is important that empirical information about the risks is available to enable informed decisions to be made. The purpose of this study was to compare the obstetric outcomes for women admitted to the Birth Centre at Royal Hospital for Women in Sydney with outcomes for women admitted to the conventional labour ward, controlling for prenatal and intrapartum risk. The findings indicate that, with the existing back-up provided by the conventional service, the outcomes for women admitted to the Birth Centre were at least as good as those of the other women. The study also shows that there are differences between the two settings in the management of the intrapartum period. The rate of intervention is substantially higher for women admitted to the Labour Ward, after risk is taken into consideration. The evaluation indicates that the Birth Centre offers a viable choice for women with relatively low obstetric risk.
