Overview
The overall goal of this proposal is to create and test an implementation protocol for in-hospital immediate postpartum diabetes screening for postpartum patients with pregnancies affected by GDM.
Description
Gestational diabetes mellitus (GDM) affects 6 to 8% of U.S. pregnancies annually and upwards of 1 in every 8 pregnancies worldwide. Pregnant individuals with GDM have higher rates of hypertensive disorders of pregnancy, cesarean delivery, and maternal mortality as compared to those without GDM. While GDM frequently resolves after delivery, up to 70% of patients will develop type 2 diabetes mellitus (T2DM) later in life10 and one third will develop subsequent diabetes or impaired glucose metabolism at the time of postpartum screening.
While postpartum screening is recommended by the American College of Obstetricians and Gynecologists (ACOG) and the American Diabetes Association (ADA) between 4-12 weeks postpartum for all patients with GDM in pregnancy, nearly 40% of patients do not attend a postpartum visit. Attendance is even lower among populations with limited resources, contributing to health disparities.
To address this issue, immediate in-hospital postpartum glucose tolerance testing has been evaluated and found to yield diagnostic values comparable to postpartum screening with the advantage of ~100% adherence. However, 2 challenges remain: currently there is a lack of widespread clinical implementation of in-hospital immediate postpartum diabetes screening.
Therefore, the overall goal of this proposal is to randomize patients to early screening during their postpartum hospitalization versus at their 6 week postpartum visit (current standard of care).
