Collection and usage attributes

Computation description:Help on this term

The number of live born babies at or after term (from 37 completed weeks gestational age) with an Apgar score of less than 7 at 5 minutes, divided by the number of live born babies born at or after term (from 37 completed weeks gestational age), and multiplied by 100.

A birth is defined as an 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. If the baby is alive the birth is a live birth. If the baby is not alive the birth is a stillbirth.

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. Term is defined as gestational age between 37 and 41 weeks.

Births included are live born babies born at or after term.

Births excluded are stillbirths and babies born before term (before 37 weeks).

Comments: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.

Data for parity, a criteria to selected females, were not available from Victoria in 2009.

The Apgar score is a system of assessing the baby’s breathing, pulse, colour, movement and reflexes at 5 minutes after birth. It is a score out of 10, with higher scores indicating better condition of the baby. A score of less than 7 at 5 minutes after birth is considered to be an indicator of complications and of compromise for the baby.

Modified from Australian Council on Healthcare Standards (ACHS) Indicator 9.1: Low 5 minute score, full term babies. This ACHS indicator is based on the definition by the Women's Healthcare Australasia Core Maternity Indicators Project (WHA 2007).
