Insights uncovered from experiencing a rise in the incidence of gestational diabetes at a Melbourne hospital. Reply to Ng E, Neff M, Sztal-Mazer S [letter]
To the Editor: We thank Elisabeth Ng and colleagues for their interest in our paper and confirmation of our data . It was interesting to read their experiences with the rising incidence of gestational diabetes mellitus (GDM) in a multi-ethnic, metropolitan maternity hospital in Melbourne (Australia) after implementing the new diagnostic criteria .
Our data have shown that implementing the new WHO 2013 diagnostic thresholds with a higher 2 h plasma glucose (2HG) cut-off value may exclude a group of women who are currently diagnosed with GDM and benefit from treatment (i.e. women with 2HG ≥7.8 but ≤8.4 mmol/l) .

They additionally comment that it is necessary to consider the rise in incidence and financial costs that would be likely to accompany an adoption of a lower 2HG threshold .
