ANSC October Update: RPA Women and Babies/Canterbury Hospital

Obstetric referrals to RPA Women and Babies – Only Fax referrals for high risk women

Please be reminded that only women requiring an early or urgent review should have the Obstetric Referral Form faxed to the antenatal clinic. Low risk women referred for routine care should bring the completed Obstetric Referral Form with them to their first hospital appointment.

The antenatal clinic has been receiving numerous faxed referrals for routine /low risk care. These are unnecessary and time -consuming for hospital staff, delaying the triage of women requiring early or urgent review.

ONLY FAX Obstetric Referral Form for high risk women requiring an early or urgent review.

If you are uncertain as to whether a woman has identifiable risk factors, please contact O&G Registrar or Clare Jordan GP Liaison Midwife ph 0425 230 662 for advice. A guide for risk selection is  outlined in the National Midwifery Guidelines for Consultation and Referral. These guidelines are used by midwife staff to categorize women at first hospital visit.

Testing process for hyperglycemia in pregnancy - high risk women 

Women who have been identified as high risk for hyperglycemia in pregnancy ( including GDM) should have early testing as per SLHD Diagnostic Testing for Hyperglycemia in pregnancy guidelines.

As per guidelines, for women not already known to have diabetes, 75g oGTT is advised from 16 weeks gestation. Several women have been referred by their GP for their 75goGTT too early in their pregnancy ie between 6-12 weeks. First trimester  (<12 weeks) testing for high risk women includes either HbA1c or fasting BGL.

Discussing models of antenatal care

Regardless of whether a GP has a special interest in obstetrics, he or she will almost inevitably be the first consultation a woman has regarding her pregnancy. During these initial visits, GPs should be responsible for informing women of all options of care, offering balanced information on the full range of options available to them throughout pregnancy, birth, and the postnatal period.

This information should include not only the different models of maternity care available locally but should also cover choices such as antenatal screening tests, antenatal education and information about birth, postnatal care, and infant care and feeding. 1

Prenatal screening – timing all important

Please be mindful of the timing for prenatal screening procedures when referring women.

Timing of prenatal screening procedures


Gestation (weeks)

Non- Invasive Prenatal Screening (NIPT)

10 weeks onwards

Combined First Trimester Screening (cFTS)

11 +1 – 13 + 6 weeks

Chorionic Villus Sampling (CVS)

11-13 weeks


15-19 weeks

As screening is performed early in pregnancy and often prior to first hospital “booking in” visit, it is the responsibility of the GP to discuss and refer women requesting prenatal screening.

Please ensure you have:  
1) Discussed prenatal screening with your patients and arranged referral for women requesting screening. NB The hospital does not arrange prenatal screening. It is the responsibility of the GP to discuss and arrange prior to first hospital visit.

2) Booked requested prenatal screening appointment according to timing of procedure (above). Women should not be attending their appointment earlier or later than the recommended gestation.

For women requesting cFTS, please ensure blood collection is attended from 11 weeks up until 3 days prior to ultrasound. Both the pathology form and ultrasound form should be completed.

All women delivering at RPA Women and Babies or Canterbury Hospital can be referred to RPA Ultrasound & Fetal Medicine for prenatal screening. The hospital has recently modified processes to accommodate more appointments. Please advise your patient to contact FMU ph. 9515 6042.
