    Definitions:

    3.1 Intact perineum: Total number of selected primipara with an intact perineum or unsutured perineal tear as a percentage of the total number of selected primipara delivering vaginally.

    3.2 Intact perineum with episiotomy: Total number of selected primipara undergoing episiotomy with an intact perineum and no perineal tear while giving birth vaginally as a percentage of the total number of selected primipara delivering vaginally.

    3.3 Perineal tear and no episiotomy: Total number of selected primipara sustaining a perineal tear and no episiotomy as a percentage of the total number of selected primipara delivering vaginally.

    3.4 Perineal tear with episiotomy: Total number of selected primipara undergoing episiotomy and sustaining a perineal tear while giving birth vaginally as a percentage of the total number of selected primipara delivering vaginally.

    3.5 Surgical repair of 3rd degree tear: Total number of of selected primipara undergoing surgical repair of the perineum for third degree tear as a percentage of the total number of selected primipara delivering vaginally.

    3.6 Surgical repair of 4th degree tear: Total number of of selected primipara undergoing surgical repair of the perineum for fourth degree tear as a percentage of the total number of selected primipara delivering vaginally.

    Selected first time mother (primipara) is a woman 20-34 years of age at the time of giving birth, giving birth for the first time at greater than 20 weeks gestation; singleton pregnancy; cephalic presentation; and at 37 to 41completed weeks gestation. A 3rd degree perineal tear is a laceration that extends from the birth canal up to and including the anal sphincter. A 4th degree perineal tear also includes the anal or rectal mucous membrane. Episiotomy is an surgical incision that enlarges the birth canal. See Methods Tab for further information. 

    Hospitals with at least 200 births in the latest year are identified individually. Total NSW (or All LHDs) includes births at home assisted by independent midwives. Totals include Other and not stated category.

    Data include all mothers who gave birth (stillbirth or live birth) in a NSW facility (or a home) regardless of place of permanent residence.

    This is a national clinical indicator defined in: Australian Council on Healthcare Standards. Obstetrics Indicator Users' Manual 2017. Obstetrics version 8. Sydney: ACHS, 2017. It is operationalised as per AIHW (AIHW 2013) reporting using the definition by Women's Healthcare Australasia Core maternity Indicators Project (WHA 2007)

    Clinical indicators 3.1-3.6: Major perineal tears and surgical repair of the perineum.

      Recent trends

      In 2018 there were 95,552 births to 94,170 mothers in NSW, a decrease of 1.8% from 97,325 births in 2014.  The percentage of multiple (twin and triplet) pregnancies has remained fairly stable over recent years at about 1.4%. 

      Between 2014 and 2018:

      • The proportion of mothers who were teenagers continued to fall, from 2.7% to 1.9%.

      • The proportion of births to mothers over 35 years of age has remained stable.

      • The rate of low birth weight (less than 2,500 grams) has remained stable, ranging from 6.0% to 6.4%.

      Aboriginal and Torres Strait Islander mothers and babies

      Between 2014 and 2018:

      • The number of reported births to Aboriginal or Torres Strait Islander mothers increased from 3,808 to 4,270, representing 3.9% and 4.5% respectively of all babies born in NSW.

      • The percentage of Aboriginal or Torres Strait Islander mothers who were teenagers fell substantially from 15.8% to 11.5%.

    • Introduction: Pregnancy and the newborn period

      Demography

      The health of Australian mothers and babies is generally good by world standards. Maternal deaths are rare, and perinatal mortality rates are low.

      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 29 years and at subsequent birth just over 30. The proportion of teenage mothers is declining.

      Burden of disease and social and economic disadvantage 

      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.

    • Interventions: Pregnancy and the newborn period

      The NSW Ministry of Health maintains two population-based surveillance systems that collect information concerning pregnancy and birth: the NSW Perinatal Data Collection and the NSW Register of Congenital Conditions. They assist in monitoring the health of mothers and babies and, maternity service planning in NSW.

      The implementation of the NSW Aboriginal Maternal and Infant Health Strategy has improved access to culturally appropriate maternity services for Aboriginal mothers.

      The NSW Maternal and Perinatal Mortality Review Committee reviews each death of a mother or newborn baby to assess the cause and identify any possible avoidable factors. This information is used to improve services for mothers and babies.
