Computation description: | The number of females having their second birth vaginally whose first birth was by caesarean section, divided by the number of females having their second birth whose first birth was by caesarean section, and multiplied by 100. 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. Included are those females who are having a singleton for their second birth and whose first birth was by caesarean section. Excluded are those females whose second birth is a multiple birth, those who are not having their second birth, and those who are having their second birth and whose first birth was a vaginal birth. |

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. From 2014, Female—caesarean section at most recent previous birth indicator, code N data item was introduced into the Perinatal NMDS. Although not an NMDS/DSS item prior to 2014, data items appear to match the data element developed by the National Perinatal Data Development Committee (NPDDC), Female—caesarean section indicator (last previous birth), code N. As a result, data from Victoria were not available in 2007 to 2009, and Western Australia in 2013. Modified from Australian Council on Healthcare Standards (ACHS) Indicator 2.1: Vaginal birth following caesarean section. This ACHS indicator is based on the definition by Women's Healthcare Australasia Core Maternity Indicators Project (WHA 2007). |
