The New South Wales Perinatal Data Collection (PDC), formerly called Midwives Data Collection (MDC) is a population-based collection covering all births in NSW public and private hospitals, as well as home births. It does not receive notifications of interstate births where the mother is resident in NSW.
The data collection has operated continuously since 1990 and covers: up to 2005, all births in NSW of at least 400 grams birth weight or 20 weeks gestation; and for 2006, stillbirths of at least 400 grams birthweight or 20 weeks gestation and all live births. The information is recorded by either the midwife or medical practitioner and includes demographic, medical and obstetric information on the mother and information on the labour, delivery and condition of the infant.
The collection has undergone three revisions over the years. Data on antenatal visits have been collected since 1994. The PDC database is compiled in the Information Management and Support Branch of the NSW Ministry of Health.
For this report, the PDC was accessed via HOIST. Data are presented for calendar years.
Perinatal deaths data for all population in NSW are obtained from the Australian Bureau of Statistics, but perinatal death data by baby's Aboriginal status are available only from the NSW PDC.
These data come from the NSW Perinatal Data Collection (PDC) where they are coded according to a completed NSW Perinatal Data Collection Form, which can be accessed via the intranet by NSW Health staff at http://internal.health.nsw.gov.au/data/collections/mdc/NSWH%20Perinatal%20Data.pdf.

• In 2010, 92,744 births occurred in NSW.
• The average woman in NSW can currently expect to give birth to 1.9 babies in her lifetime.
• Among NSW mothers:
teenage mothers account for 3% of all births, while mothers aged 35 years and over account for 24% of all births
around 55% of mothers take folate supplements, both one month before and in the first trimester of pregnancy, as recommended to prevent neural tube defects
around 79% make their first antenatal visit before 14 weeks and 92% before 20 weeks gestation
around 12.7% report smoking during pregnancy, with this percentage varying markedly according to Local Government Area of residence.
• Among NSW babies:
around 7.3% are born prematurely, and 6.0% are of low birth weight
babies born to teenage mothers had the highest rates of low birth weight (7.9%)
there were 838 perinatal deaths in NSW in 2009. Almost half of the perinatal deaths are related to the length of gestation and fetal growth.
The health of Australian mothers and babies is generally good by world standards. Maternal deaths are rare, and perinatal mortality rates continue to decline.
The average woman in NSW can currently expect to give birth to 1.9 babies in her lifetime.
NSW mothers are getting older with the mean maternal age at first birth around age 29 years and at subsequent birth over 30 and a half years. The proportion of teenage mothers among all mothers is declining.
Aboriginal mothers and babies, those from socioeconomically disadvantaged areas and some overseas born mothers and their babies, continue to experience worse outcomes than other NSW mothers and babies.
More than 90% of NSW mothers commence antenatal care in the first half of pregnancy, however there are differences between regions of NSW, Aboriginality and country-of-birth.
The NSW Department of Health maintains two population-based surveillance systems the NSW Midwives Data Collection and the NSW Register of Congenital Conditions. These assist in monitoring health of mother and babies and service planning in NSW.
The implementation of the NSW Aboriginal Maternal and Infant Health Strategy has been very successful in improving access to culturally appropriate maternity services for Aboriginal mothers.
Neonatal Intensive Care Units have been established in NSW hospitals to ensure that the best possible specialist care is provided to babies that require it.
The NSW Maternal and Perinatal Committee reviews each maternal death to identify any possible avoidable factors and to determine whether the death was related to pregnancy and its management or whether it was incidental.
