Computation description:Help on this term

Number of selected women giving birth for the first time who gave birth by caesarean section.

* Selection criteria: Women included are those who gave birth for the first time and met all of the following criteria:

  • aged between 20 and 34 years

  • gestational age at birth between 37 and 41 completed weeks

  • pregnancy has one baby only (singleton) 

  • the presentation of the baby is vertex (baby’s head was at the cervix)

    Excluded are those women who have given birth prior to the current birth or who did not meet the selection criteria.

     Inclusion codes and description 

    Data Element Code Description
    Birth Method 4 Caesarean section
    Birth plurality 1 Singleton
    Birth Presentation 1 Vertex

    Presented as a number per 1,000 selected women.

    Rates are directly age standardised to the 2001 Australian female population aged 20–34, using 5-year age groups: 20-24, 25-29 and 30-34.

    For more information about age-standardisation in general see http://meteor.aihw.gov.au/content/index.phtml/itemId/327276

    Analysis by Statistical Area Level 3 (SA3) is based on usual residence of the mother.

Disaggregation:Help on this term

SA3 by :

  • Remoteness (ASGC Remoteness structure) and Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socioeconomic Disadvantage (IRSD)

State and territory by:

  • Indigenous status

  • Patient elected accommodation status

Cells of less than 5 have been suppressed. This is the lowest level of suppression that all states and territories have agreed to for the release of data from the National Perinatal Data Collection.            

Crude rates have been suppressed where the denominator is less than 100, for reliability purposes. The corresponding age-standardised rate has also been suppressed in these cases.              

In addition, age-standardised rates have been suppressed where the denominator for any age-stratified groups have fewer than 10 individuals.

Methodology:Help on this term

Data elements are from the Perinatal national minimum data set (NMDS) or have been provided as voluntary non-standardised items by the states and territories. Records with data that are missing, not stated or not interpretable have been excluded from the denominator. 

A birth is defined as the event in which a baby comes out of the uterus after a pregnancy of at least 20 weeks gestation or weighing 400 grams or more. Caesarean section is an operative procedure to remove the baby through an incision through a woman’s abdomen and uterus.

Gestational age is a clinical measure of the duration of the pregnancy. For the National Perinatal Data Collection gestational age is reported as completed weeks.

Patient elected accommodation status is available from all jurisdictions from 2006.

Source of definition: Australian Council of Healthcare Standards (ACHS) Indicator 1.4: Selected women giving birth for the first time undergoing caesarean section. This ACHS indicator is based on the definition by Women's Healthcare Australasia (WHA) Core Maternity Indicators Project (CMIP).
