Background and Aims: Continuous glucose monitoring (CGM) improves glycemic control and reduces complications in patients with type 1 diabetes (T1D). This study examines the frequency of diabetic ketoacidosis (DKA) and hospitalization among patients with T1D and COVID‐19 and CGM use.

Methods: This analysis included all patients with T1D who tested positive for COVID‐19 (n = 241) in the T1D Exchange COVID‐19 Registry. Data for the registry was collected using an online survey tool. Healthcare teams from 52 endocrinology clinics across the U.S. completed the survey using electronic medical records between April and September 2020.

Results: Of the 241 patients included in this analysis, 53% were CGM users and 47% were CGM non‐users. CGM non‐users were more likely to be on public insurance compared to CGM users (68% vs. 34%). HbA1c in the CGM group was lower compared to non‐users (Median [IQR],%: 8.1 [2.6] vs 10.0 [3.3] [p < 0.001]), and DKA was less frequent for CGM users relative to the non‐users (9% vs 36%) [p < 0.001]. Further, patients who did not use CGM were more likely to be hospitalized (33% vs 13%) [p < 0.001] or need ICU care [30% vs.6%) [p < 0.001] than patients who used CGM.
