Computation description: | The number of selected females giving birth for the first time who gave birth by non-instrumental vaginal birth, divided by all selected females, and multiplied by 100. Selected females criteria: Females included are those who gave birth for the first time and met all of the following criteria:
Excluded are those females who have given birth prior to the current birth or who did not meet the selection criteria. A birth is defined as the complete expulsion or extraction from a female, of a product of conception of 20 or more completed weeks of gestation or of 400 grams or more birthweight. A non-instrumental vaginal birth is one in which the baby is born through the vagina without the assistance of instruments (vacuum or forceps). |

Comments: | 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 a permissible value have been included in the denominator. For Tasmania prior to 2012, presentations via caesarean births were not reported by hospitals still using paper-based forms. Where a caesarean section occurred the presentation was recorded as 'Not stated'. Presentations via caesarean births was included in the paper-based form from 1 January 2013. As a result, Tasmania can only be reported 2013 onwards for selected females. Data for parity, a criterion to selected females, were not available from Victoria in 2009. Source of definition: Australian Council on Healthcare Standards (ACHS) Indicator 1.1: Selected women giving birth for the first time who have a spontaneous vaginal birth. The ACHS defines a spontaneous vaginal birth as a vaginal birth, regardless of onset of labour, which is not assisted by forceps or vacuum and is not a vaginal breech delivery. This ACHS indicator is based on the definition by Women's Healthcare Australasia Core Maternity Indicators Project (WHA 2007). |
