Abstract

Aims: GDM affects 16% of UK pregnancies1. Its recognition and treatment can reduce obstetric and perinatal complications. We aimed to compare the population of women diagnosed with GDM according to NICE and WHO criteria and how this affected pregnancy outcomes. Methods: This was a retrospective audit of women who were booked to deliver at Russells Hall Hospital and had an OGTT during September 2019. We compared the number and pregnancy outcomes of women diagnosed with GDM based on WHO and NICE criteria. Results: 168 women aged 31 ± 5.2 years (mean ± SD) were studied. 29 (17.2%) women met WHO criteria for GDM and 30 (18%) met NICE criteria. Women who had GDM with NICE were managed in a joint diabetes antenatal clinic. Discordance was seen in 15 (8.9%) cases. 7 (46.7%) of these were identified as having GDM with WHO only; 8 with NICE only. Compared to women with GDM with NICE only, those with GDM with WHO only were younger (29 ± 4.6 years vs. 35 ± 5.0 years), more frequently required emergency caesarean sections (4 (57.1%) vs. 1 (12.5%)) and more frequently gave birth to large for gestational age (>4 kg) babies (2 (28.6%) vs. 1 (12.5%)). Conclusions: Transitioning from NICE to WHO criteria would not significantly change the number of women attending clinic. However, it helps identify women more likely to have complicated births and highlights a younger population more likely to have future pregnancies. Reference 1.
