About

The purpose of this study is to develop an implementation protocol and test the feasibility and acceptability of a first trimester screening protocol for the early detection of gestational diabetes mellitus (GDM).

Full description

Gestational diabetes mellitus (GDM) is an important contributor to both maternal and neonatal morbidity and mortality in pregnancy. GDM has lifelong complications including an increased risk of developing type 2 diabetes mellitus and cardiovascular disease for women, and their offspring are at higher risk of being obese and also having diabetes in childhood and adolescence. Approximately 1 in 8 pregnancies is impacted by gestational diabetes mellitus worldwide. First trimester GDM screening is varied due to conflicting national guidelines, and the best strategy is unknown. The goal of the proposed research is to develop an implementation protocol and test the feasibility and acceptability of a first trimester screening protocol for the early detection of GDM. The investigators will utilize a pilot randomized controlled trial to recruit 80 high-risk pregnant women in the first trimester, of whom half will receive protocolized early GDM screening with serum biomarkers before 12 weeks and the remaining half will receive the current standard of care with screening between 24 and 28 weeks of gestation with possible early screening based on provider discretion.

Enhanced First Trimester GDM Screening
Experimental group
Description:
Women who are randomly assigned to this condition will be required to have early glucose screening with a prediction model composed of additional clinical risk factors and serum biomarkers (triglycerides, PAPP-A, and lipocalin-2) with their initial prenatal laboratory assessment.
Treatment:
Diagnostic Test: Enhanced First Trimester GDM Screening
Standard of Care GDM Screening
Active Comparator group
Description:
Women who will be randomized to the comparison condition of usual standard of care will undergo routine standard of care. The standard of care will consist of routine screening for diabetes in pregnancy between 24 to 28 weeks of gestation via the two-step screening method with possible early screening with either plasma fasting glucose, oral glucose tolerance test, or hemoglobin A1c at the providers discretion to represent true clinical practice.
Treatment:
Diagnostic Test: Routine Gestational Diabetes Screening
