Automated Insulin for Management of Intrapartum Glycemia

The goal of this clinical trial is learn if automated insulin delivery (AID) systems can be used for glucose management during labor/delivery for pregnant people with type 1 diabetes (T1D). The main questions this study aims to answer are * What are the neonatal glycemic outcomes with use of AID systems during labor/delivery? * Do patients report higher birth satisfaction with use of AID systems during labor/delivery? * Are glycemic parameters like time-in-range (TIR) better with use of AID systems during labor/delivery? Researchers will compare AID systems to intravenous (IV) insulin (the current standard of care for glucose management during labor/delivery) by randomly assigning participants to one or the other.

Inclusion Criteria: * Currently pregnant at ≥ 34 weeks * Known diagnosis of type 1 diabetes ≥ 1 year * Use of commercially available AID system since at least 28 weeks gestation * Singleton pregnancy * English- or Spanish-speaking Exclusion Criteria: * Multifetal gestation * Planned cesarean delivery * Use of medications known to interfere with glucose metabolism * Intrauterine fetal demise * Physical or psychological disease likely to interfere with the conduct of the study and/or the ability to participate in own healthcare
