An estimate of the need for continuous glucose monitoring in type 2 diabetes with intensive insulin treatment in secondary healthcare
Authors' conclusion
The proportion of persons with T2DM in secondary healthcare undergoing intensive insulin treatment who could be candidates for CGM corresponded to only a minor fraction of persons with T1DM in the same region, irrespective of any HbA1c criteria applied.
Study context
- Population
- All persons with T1D or T2D with ≥1 contact to a diabetes outpatient clinic, Central Denmark Region, September 2021 to September 2022
- Participants
- 4,315 vs 6,179
- Exposure
- T2D vs T1D
- T2DMn = 4,315
- T1DMn = 6,179reference
- Outcome
- Proportion of persons with T2D on intensive insulin treatment in secondary healthcare who could be continuous glucose monitoring (CGM) candidates, by HbA1c criteria
