Patient Versus Provider-led Titration of Insulin for Glycemic Control in Gestational Diabetes (EMPOWER)

Summary

We propose a pragmatic, unblinded, randomized controlled, single center trial of 56 pregnant individuals with Gestational diabetes mellitus (GDM). Our study proposes a pragmatic randomized control trial of patient led rapid titration of basal insulin compared to standard therapy. There is a planned subgroup analysis of patients with and without concomitant metformin usage. Patients will continue routine clinic visits. Patients who are initiated on basal insulin or started on night-time basal insulin within 7 days will be approached about the study. Patients who agree to be enrolled will sign informed consent.
