The gap in the use of insulin pumps and continuous glucose monitors (CGMs) among Black and white Medicare beneficiaries widened from 2017-2019, according to new research published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Reducing health disparities is a major public health goal in the United States, and these disparities include the use of diabetes technology. All Medicare beneficiaries with type 1 diabetes should have equal access to diabetes therapy, but research shows there are inequities associated with race and ethnicity.
The researchers determined the prevalence of diabetes technology use by race and ethnicity using data from the Medicare fee-for-service database between 2017-2019. They found CGM and insulin pump use grew among all groups between 2017-2019, but the increase was greatest for white patients.
The prevalence of insulin pump use was low for Black beneficiaries in 2017 and slightly increased from 2017 to 2019 (from 3.9% to 4.6%). It was higher in 2017 for white beneficiaries and increased substantially from 2017 to 2019 (from 14.0% to 18.2%). About 25% of white beneficiaries were using CGMs in 2019, compared to 12% of Black beneficiaries – a gap that has widened since 2017.
