Permissive Versus Strict Intrapartum Glucose Management in Type 1 Diabetes (PRISM-T1D)

Participants will be randomized in a 1:1 fashion to one of two intrapartum glycemic control options: permissive (70-140 mg/dL) or strict (70-110 mg/dL). Participants and clinicians will be unblinded. Once randomized, an order set will be entered into the EMR that will alert pharmacy and nursing colleagues to the appropriate intrapartum glycemic control protocol.

Patients will be asked to wear an optional Continuous Glucose Monitor (CGM) to utilize during labor for research purposes. The CGM will be removed prior to hospital discharge and data will be extracted by trained research personnel. All participants already utilize a CGM device as part of standard of care as part of Hybrid Closed Loop (HCL) therapy. No clinical decisions will be made based upon data from the research CGM device. This data will not be extracted until after hospital discharge.
