Comments:Help on this termData 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 included in 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.

Induction of labour is a set of procedures (pharmacological and/or instrumental) to start the uterus contracting and begin the process of labour.

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 for all jurisdictions from 2006.

Source of definition: Australian Council of Healthcare Standards (ACHS) indicator 1.2, Selected women giving birth for the first time who undergo induction of labour.
