Objective: Determine if real-time CGM increases glucose TIR compared to current standard care of GDM using self-monitoring blood glucose (SMBG; ~4 times per day). Methods: Randomized (2:1), open label trial comparing real-time CGM to SMBG alone (with blinded CGM) to manage persons w/ GDM. Subjects with 7 days of CGM data were excluded. Primary outcome: glucose TIR (60-140mg/dL) from randomization to delivery admission, comparing the CGM to SMBG group using two-sample t-tests. Results: After exclusions, CGM n=74 driven by higher daytime TIR 140 mg/dL. Conclusion: Persons with GDM achieve higher TIR using real-time CGM compared to SMBG alone. Disclosure A.M. Valent: None.
