Gestational Diabetes Mellitus (GDM) is a frequently noted complication of pregnancy with potential for adverse effects on the mother and foetus, particularly around delivery. It is not clear if additional investigations are helpful in predicting complications such as macrosomia, shoulder dystocia and post partum haemorrhage.
A comprehensive audit was undertaken at a level 2 hospital of all patients diagnosed with GDM between year 2016 and 2017. Women with GDM at this hospital were routinely screened with HbA1c, TSH, Urate and Urine PCR. We recorded maternal gestation at diagnosis, weight at booking in visit and at 36 weeks gestation, as well as type of GDM (diet-controlled, metformin, insulin). Outcomes reviewed were maternal mode of delivery, estimated blood loss and shoulder dystocia. We also collected neonatal data on birth weight. Statistical analysis was performed to evaluate the relationship between biochemical markers and study outcomes.
Statistical analysis is being undertaken and results are pending. We aim to present the relationship between these screening tests and the study outcomes and comment on the usefulness of these tests as part of antenatal care.
The results of this investigation will help to inform whether the use of these baseline markers have a relationship to maternal and foetal outcomes associated with GDM.
