What this trial studies

This observational study aims to establish reference values for HbA1c that can predict adverse pregnancy outcomes in women diagnosed with gestational diabetes mellitus (GDM). It involves collecting data on HbA1c and fructosamine levels during antenatal care and documenting various pregnancy outcomes, including complications and modes of delivery. The study follows the NICE guidelines for diagnosing GDM and seeks to fill a knowledge gap regarding optimal HbA1c levels for managing this patient population. By analyzing these relationships, the study hopes to improve care for women with GDM.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women with a confirmed diagnosis of gestational diabetes and a singleton pregnancy.

Not a fit: Patients with major fetal anomalies, severe anemia, autoimmune diseases, or pre-existing diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better management strategies for pregnant women with gestational diabetes, potentially reducing adverse outcomes.

How similar studies have performed: While there have been studies examining HbA1c in relation to pregnancy outcomes, this specific approach to establishing reference values for GDM is relatively novel.
