All women delivering at Chelsea and Westminster Hospital are screened at booking with a random blood glucose and at 26 weeks with a 50g glucose load (O'Sullivan's). If screen positive (≥7.8mmol/l), a full GTT is offered. Our aim was to investigate the outcome of pregnancy in those women who only had an abnormal 1 h reading and would have been diagnosed as normal if NICE guidelines were followed. Of the 426 women diagnosed with GDM in the study period, 45 (10.6%) had an abnormal 1 h value. Complete data were retrieved for 37 women, 13 (35%) had previous GDM and 7 (19%) a family history of diabetes. The group ethnicity was 57% white, 11% Asian, 11% Black, 11% Chinese, 5% other and 5% not recorded. Home blood glucose monitoring aimed for fasting/premeal glucose levels of 3.5 mmol/l-5.5mmol/l and 1 h post meal of ≤7. 8mmol/l. 18 (49%) of the women needed treatment with metformin (8%) or insulin (41%). Macrosomia was found in 5%, polyhydramnios in 5% and pre-eclampsia in 8% of women. There was one case each of shoulder dystocia and neonatal hypoglycaemia. The authors conclude that the inclusion of the 1 h value detects women who need treatment for hyperglycaemia to reduce maternal and fetal morbidity (as recently reported by HAPO study). ER -
