Further data development / collection required:Help on this termSpecification: Interim

Work is currently under way to develop a standard definition for gestation at first presentation for antenatal care.

Agreed definition of first antenatal visit and implementation into NMDS and associated collections needed.

Work is also required to improve Indigenous identification.

Investigation is required to investigate mechanisms for obtaining data from the private sector.
Other issues caveats:Help on this termData for this indicator are available for three jurisdictions for 2010 reporting (NSW, SA and NT). Comparability between data currently collected may be limited by different definitions of first antenatal visit.

Disaggregations are subject to data quality considerations. Some disaggregations may result in numbers too small for publication.

Data for all jurisdictions will not be available until the 2010 reference year, at the earliest. Data on gestation at first antenatal visit has been collected by NSW since Jan 2006 and South Australia since Jan 2007. Victoria commenced collecting the information in January 2009, and Queensland in July 2009.
