Association Between Self-Monitored Blood Glucose and Continuous Glucose Monitoring in Youth With Type 1 Diabetes and Medicaid Insurance
Authors' conclusion
Patients using CGM demonstrated improvement in HbA1c regardless of prior SMBG. Increased engagement with CGM likely promoted increased insulin boluses. Therefore, restriction of CGM to those with SMBG ≥4 daily checks is an unnecessary barrier, excluding those who could potentially benefit the most.
Study context
- Population
- Youth with T1D and Medicaid who started CGM after January 2019, at two large health care systemsfollowed 6 months
- Participants
- 78 participants
- Exposure
- Baseline self-monitored blood glucose (SMBG) <4 vs ≥4 checks daily before CGM start
- Outcome
- CGM adherence and HbA1c over time
- Follow-up
- 6 months
Methodological detailstwo health care systems, mixed-effects linear regression model
- Two health care systems
- Mixed-effects linear regression model
Main finding
As reported in the abstract
CGM adherence · 3 months
- CGM adherence similar between SMBG frequency groups at 3 months and sustained at 6 months
- Between SMBG <4 and SMBG ≥4: P = 0.97
Observational data: associations, not effects.
Further findings
HbA1c improvement · 3 months
HbA1c improvement · 3 months
- HbA1c improved in both groups at 3 months, larger improvement with SMBG <4; sustained at 6 months
Patient surveys
- High engagement with CGM and increased insulin boluses after initiation (n = 35 surveyed)
