Background: After birth, 2% of women with GDM will continue to have diabetes and 50% will develop Type 2 diabetes (1). Australian Diabetes In Pregnancy Society (ADIPS) guidelines recommend an Oral Glucose Tolerance Test (OGTT) 6-8 weeks postpartum for women who had GDM (2). In 2010 170 women with GDM were registered with NDSS from Central Coast NSW, up from 130 in 2007. The NSW Central Coast Local Health District (CCLHD) antenatal clinic consists of a group followed by individual appointments. Group participants are informed and receive literature advising them to have an OGTT at 6-8 weeks postpartum and at least every 2 years.

Aim: Are women attending the CCLHD antenatal clinic having a 6-8 week postpartum OGTT?

Methods: Women who attended antenatal clinics between July 2010 and Nov 2010 were asked scripted questions over the phone relating to postpartum diabetes screening. Three attempts were made to contact women between March 2011 and May 2011. Women were excluded if non English speaking or, if their child was deceased.

Results: 41 women from antenatal clinic records met the inclusion criteria. 10 women were uncontactable, 1 did not wish to participate and 30 answered questionnaires. The tables below show responses to the questionnaires.

Conclusion: This quality activity found less than 30% of women had their follow up OGTT. A systematic literature review by Kim et al identified 38-100% of women had OGTT.3,4   Concerning is that most women did not forget the test, but it was inconvenient due to time, family commitments and disliking the test.
