ORCHID (Gestational Diabetes Study)

The Optimisation of Rural Clinical & Haematological Indicators of Diabetes (ORCHID) study, also referred to as the Gestational Diabetes study, is a large scale project looking for a simpler, more cost effective way to screen for gestational diabetes mellitus (GDM) in regional and remote communities. Currently, only 50% of pregnant women living in rural WA are screened for GDM using the Oral Glucose Tolerance Test (OGTT).

This study, which is being conducted by the Rural Clinical School of WA through the University of WA and in association with the University of Notre Dame, has recruited participants from the South West, Mid West, Great Southern, Goldfields and Kimberley regions of WA. In total, 691 participants were recruited to the study surpassing the original target of 600.

The research team presented the results from a retrospective audit of GDM at the Rural Medicine of Australia conference in October 2016 and the Gestational Diabetes Audit has been submitted to the Australian Journal of Rural Health for publication. There are five proposed papers linked to the funding provided by the Lishman Health Foundation for this project due to be published in 2019. One of these papers will look at HbA1c and the relationship with OGTT and birth outcome data. Another paper will focus on the measurement of serum GA and the relationship with OGTT and birth outcome data. This paper will look at how the OGTT is failing to detect GDM in the real world.
