A poster presented at the Academy of Managed Care Pharmacy’s (AMCP) annual meeting in New Orleans, LA, shared data from a health initiative by Metro Nashville Public Schools. The employer provided CGM devices as a pharmacy benefit without prior authorization. This policy change led to a two-fold increase in CGM utilization among employees aged 18 to 64 years with T1D and T2D regardless of treatment regimen. The retrospective analysis, covering 184 participants, showed significant improvements in glycemic control associated with CGM use. Specifically, average A1c decreased from 8.7% to 7.9% and from 7.6% to 6.8% among those with T2D treated with insulin and not-treated with insulin, respectively. Additionally, CGM use resulted in a significant improvement in the proportion of individuals meeting the HEDIS and ADA HbA1c targets of <8.0% and <7.0%, respectively. These results underscore the potential benefits of CGM for improving diabetes management through streamlined health care payer and purchaser coverage.
