Impact of Continuous Glucose Monitor on Health Care Resource Utilization in Adults with Type 2 Diabetes Managed by Noninsulin Therapies
Authors' conclusion
This analysis demonstrated an association between CGM acquisition and reductions in HCRU in adults with T2D treated with noninsulin therapies.
Study context
- Population
- Adults ≥18 years with T2D treated with noninsulin therapies, continuous glucose monitoring (CGM)-naive before CGM acquisition, with continuous medical/pharmacy insurance coverage during the 12-month preindex and postindex periods, United States
- Participants
- 20,468 adults
- Exposure
- 12 months after vs 12 months before CGM acquisition
- Outcome
- Changes in all-cause hospitalizations (ACH), ED visits, acute diabetes complications, hyperglycemic events (HGE) and DKA
- Follow-up
- 12 months following CGM acquisition
Methodological detailsretrospective database study, pre-post comparison
- Retrospective database study
- Pre-post comparison
