Overview of current landscape

Revised data set:

• new data items

• user manualElectronic or paper – what are we doing from 1 January 2009?

Trial of electronic transmission

•Review of data elements has been in progress since 2006

▫ national data reporting requirements

▫ capture mortality information.

•Data is collected, analysed and reported annually for a

calendar year.

Current landscapeVictorian Perinatal Data Collection Unit (VPDCU) is authorised to collect information on every birth in Victoria over 20 weeks gestation or more than 400gms birth weight.

A revised perinatal data collection will be implemented as of 1 January 2009.

New data items

intended to take place is now required.

occurred is now required.

gestation.– NN Average number of cigarettes smoked per

day at 20 or more weeks of pregnancy– 98 Occasional smoking (less than one)– 99 Not stated / inadequately described.

Indigenous status - baby

Gravidity

• The total number of pregnancies, including the current one:– record the numbers of known pregnancies

regardless of the gestation and outcome– pregnancies of multiple fetuses should be

counted as only one pregnancy. For example, a twin pregnancy is counted as one pregnancy, even though it has two outcomes.

Parity• The total number of previous pregnancies

resulting in births at 20 or more weeks.– Record the number of known previous

pregnancies that ended in births at 20 or more weeks gestation, that is, count all pregnancies that result in livebirths - survived 28 days, livebirths-neonatal death, and stillbirths.

counted as only one pregnancy. For example, a twin pregnancy is counted as ‘1’ pregnancy, even though it has two outcomes.

Why are the VPDCU collecting the new data items?

• There is a demand from various sources including, DHS, researchers and health agencies, to have an understanding of the trends and outcomes in maternal and perinatal mortality and morbidity reporting.

• Previously the focus has been on mortality; the current view is to concentrate more on morbidity.

• National and internationally perinatal collection units are now capturing and reporting on more morbidity items

• Some of the new items on the perinatal form include: BMI, smoking and baby’s indigenous status.

How will these new data items be used by the VPDCU?

• To inform policy.

• To inform the recommendations that come from the Consultative Council in Obstetric and Paediatric Mortality and Morbidity (COPPM).

• To improve education, health resources, and assist in providing information for the planning of neonatal care units.

• The User Guide is a working draft, feedback on any area of reporting would be appreciated.

• The User Guide is available on the website for viewing and comment: www.health.vic.gov.au/perinatal/pubs/guide.
