Background: The T1D Exchange Quality Improvement Collaborative (T1Dx-QI) is a learning network of over forty US type 1 diabetes clinics. Clinics share best-practice ideas for quality improvement and use data for population health research. This study benchmarks continuous glucose monitor (CGM) use across pediatric clinics in the T1Dx-QI.

Method: T1Dx-QI clinics report monthly on critical metrics, including the percentage of patients with hemoglobin A1c (HbA1c) <7% or using CGM. Median values for each site were calculated using Lahey P run charts between July 2020 and June 2021. These results are shared non-anonymized internally among participating T1Dx-QI clinics.

Results: Across 17 T1Dx-QI clinics, the percentage of patients using CGM ranged from 23% to 85% (Figure 1; mean and median CGM use were 61.3% and 61.7%, respectively) . Median HbA1c values ranged from 7.4% to 9.2%. There were no observed differences in CGM use by patient population size.

Conclusion: The T1Dx-QI benchmarks key clinical metrics to support quality improvement, share best practices, and promote learning across clinics.
