Context Health inequity is often associated with race-ethnicity. Objective To determine the prevalence of insulin pump therapy and continuous glucose monitoring (CGM) among Medicare beneficiaries with type 1 diabetes (T1D) by race-ethnicity, and to compare diabetes-related technology users with nonusers. Design The prevalence of technology use (pump, CGM) was determined by race-ethnicity for enrollees in coverage years (CY) 2017-2019 in the Medicare fee-for-service database. Using CY2019 data, technology users were compared with nonusers by race-ethnicity, sex, average age, Medicare eligibility criteria, and visit to an endocrinologist. Setting Community Patients or Other Participants Beneficiaries with T1D and at least 1 inpatient or 2 outpatient claims in a CY. Intervention(s) Pump or CGM therapy, visit to an endocrinologist. Main Outcome Measure(s) Diabetes-related technology use by race-ethnicity groups. Results Between 2017 and 2019, CGM and insulin pump use increased among all groups. Prevalence of insulin pump use was Conclusions Significant race-ethnicity associated differences existed in T1D management. The gap in diabetic technology adoption between Black and White beneficiaries grew between 2017 and 2019.
