1BACKGROUND

While it is not possible to eliminate all potential adverse outcomes from a pregnancy and/or birth, it is possible to predict and minimise preventable adverse outcomes and reduce the likelihood of other adverse events occurring. This can be achieved by providing appropriate management and care of the pregnant woman from conception through to the postpartum period. Good management means that care is provided by the most appropriately qualified health professional or team of professionals, and in the most appropriate setting.

Whilst grouping women according to their associated risks is necessary to assist health care services develop and institute protocols and guidelines for admission and safe clinical practice, it is also critical that each pregnancy is considered and managed individually. Continued consideration of potential risks and ongoing review by health care professionals throughout each pregnancy is essential, given that adverse events can emerge unexpectedly even in low-risk pregnancies.
