Options for screening for gestational diabetes mellitus during the SARS‐CoV‐2 pandemic
Open accessAbstract
The balance between avoiding severe acute respiratory syndrome coronavirus‐2 contagion and reducing wider clinical risk is unclear for gestational diabetes mellitus (GDM) testing. Recent recommendations promote diagnostic approaches that limit collection but increase undiagnosed GDM, which potentially increases adverse pregnancy outcome risks. The most sensitive approach to detecting GDM at 24–28 weeks beyond the two‐hour oral glucose tolerance test (OGTT) is a one‐hour OGTT (88% sensitivity). Less sensitive approaches use fasting glucose alone (≥5.1 mmol/L: misses 44–54% GDM) or asking ~20% of women for a second visit (fasting glucose 4.7–5.0 mmol/L (62–72% sensitive)). Choices should emphasise local and patient decision‐making.

Simplifying the diagnosis of GDM in order to avoid the risk of COVID-19 infection was associated with the risk of not diagnosing GDM by as much as 20-30%.
“However, simplifying the diagnosis of GDM in order to avoid the risk of COVID-19 infection was unfortunately associated with the risk of not diagnosing GDM by as much as 20–30%, which may affect obstetric outcomes [63,64,65].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
