Background and Aim
This project focuses on adverse maternal and perinatal outcomes in women that have socio- demographic, medical, surgical and intrapartum risk factors and the development of strategies to mitigate this risk in Australia. Using the Mater Hospital, QLD and national perinatal data sets, the project aims to identify maternal and perinatal factors associated with adverse perinatal outcomes and to develop a model for identification of at–risk pregnancies in Australia.
