Assessment of Glucose Monitoring Adherence in Medicare Beneficiaries with Insulin-Treated Diabetes
Authors' conclusion
Race is associated with increased hospitalizations and costs associated with diabetes care and absence of any form of BGM was associated with higher rates of comorbidities. Persons of color were less likely to use rtCGM despite Medicare coverage.
Study context
- Population
- Medicare beneficiaries using intensive insulin therapy, January–December 2018
- Participants
- 1,329,061 beneficiaries
- Exposure
- Glucose monitoring method and adherence by race/ethnicity
- Outcome
- Glucose monitoring method and adherence
Methodological details12-month retrospective analysis, Centers for Medicare & Medicaid Services data
- 12-month retrospective analysis
- Centers for Medicare & Medicaid Services data
Main finding
As reported in the abstract
No record of glucose monitoring
38.14%
Blood glucose monitoring (BGM) nonadherent
35.42%
Observational data: associations, not effects.
Further findings
Nonadherent to BGM or no monitoring record among beneficiaries with CCI risk score ≥2 (n=629,514)
- Nonadherent to BGM or no monitoring record
- 466,646 (74.13%)
Real-time continuous glucose monitoring (rtCGM) adherence by race/ethnicity
- White rtCGM adherent
- 3.65%
- Black rtCGM adherent
- 1.58%
- Hispanic rtCGM adherent
- 1.28%
- White vs Black and vs Hispanic, significantly larger
- both P < 0.0001
Hospitalizations and costs by race within CCI risk score ≥2
- Hospitalizations and costs higher for Black and Hispanic vs White beneficiaries regardless of glucose monitoring method
