Interprofessional Continuous Glucose Monitoring for Underserved Adults with Type 2 Diabetes on Insulin or Secretagogues

Abstract

Background: Literature describing continuous glucose monitoring for underserved patients, including those with type 2 diabetes or at risk for hypoglycemia, is lacking. Methods: An interprofessional internal medicine residency team implemented a blinded CGM service for underserved adults with type 2 diabetes with at-goal glycated hemoglobin (A1C) taking insulin or secretagogues. Results: The 2-week blinded CGM service (N=44) significantly reduced time in hypoglycemia (<70 mg/dL) by 4.1% (P=0.0038). Time-in-target-range increased significantly (4.31%, P=0.025). Body weight, number of medications, and daily insulin dose decreased significantly. Overall, A1C remained stable, indicating no worsening of diabetes control associated with the service. Conclusions: The interprofessional blinded CGM service influenced improved glycemic control in this vulnerable population.
