Comments:Help on this term

Data elements are from the Perinatal national minimum data set (NMDS). 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. Births included are those for babies born at or after 40 weeks gestation. This includes stillborn babies and babies from a multiple birth.

Gestational age is reported as completed weeks.

Births excluded are those for babies born before 40 completed weeks gestational age, that is before 40 weeks and 0 (zero) days.

Modified from Australian Council on Healthcare Standards (ACHS) Indicator 8.1: Babies with severe intrauterine growth restriction. This ACHS indicator is based on the definition by Women's Healthcare Australasia (WHA) Core Maternity Indicators Project (CMIP).
