Wherry K, et al. - In type 1 diabetes (T1D) management, there exist significant race-ethnicity related disparities. From 2017 to 2019, the observed gap in diabetic technology adoption between Black and White beneficiaries increased.

• Enrollees in coverage years (CY) 2017-2019 in the Medicare fee-for-service database were analyzed to report prevalence of insulin pump therapy and continuous glucose monitoring (CGM) among Medicare beneficiaries with T1D based on race-ethnicity, and to compare diabetes-related technology users with non-users.

• In all groups, an increase in CGM and insulin pump use was evident between 2017 and 2019.

• In Black and Other beneficiaries, the estimated prevalence of insulin pump use was <5%; it rose from 14% to 18% among White beneficiaries.

• In CY2019, a pump was used by 57% of White patients vs 33.1% of Black and 30.3% of Other patients.

• Relative to White patients, Black ones had more chances to be eligible because of disability/end-stage renal disease or to be Medicare/Medicaid eligible, whether using technology or not.

• There were significant race-ethnicity disparities between technology users and non-users for all assessed factors except visiting an endocrinologist.
