Gestational diabetes mellitus (GDM) is usually diagnosed using the oral glucose tolerance test (OGTT), sometimes following a glucose challenge test (GCT) in women with risk factors for GDM. Since the COVID-19 pandemic, Our Lady of Lourdes Hospital (OLOL) has been using the GCT alone to screen for GDM. However, national guidelines recommend using the OGTT. We audited our practice to compare outcomes between using OGTT and GCT. We reviewed data from all women who gave birth at OLOL in 2019 and 2022 (n = 5804), when OGTT and GCT were used, respectively, to diagnose GDM. We compared maternal outcomes such as delivery methods, induction rates and treatment of GDM, as well as neonatal outcomes such as birth weight and admission to neonatal intensive care (NICU). More women were diagnosed with GDM in 2022 using GCT than in 2019 with OGTT (18.3% vs 12.5%, P < 0.001). Induction of labour was higher in 2022 (36.9% vs 31.7%, P < 0.001), but delivery methods were largely unchanged. Treatment was similar both years with just under 2/3 using insulin. Gestational age at delivery showed no difference (36.7 ± 2.7 vs 35.9 ± 2.74 weeks, P = 0.16). There was no statistically significant difference in Caesarean section rates. Rates of macrosomia, preterm births, and NICU admissions were similar in both years. Using the GCT alone leads to more women being diagnosed with GDM but does not improve outcomes for mothers or babies. This supports returning to the OGTT as the main test for GDM, following national recommendations.
