Telemedicine Visit Use and Glycemic Control in Patients With Diabetes
Authors' conclusion
Higher rates of phone but not video visits were associated with worse glycemic control in patients with higher baseline HbA1c. Additional research is needed to determine possible causes and strategies for bridging the digital divide.
Study context
- Population
- Adults with diabetes with baseline HbA1c in 2020, ≥2 diabetes visits in 2021 and outcome HbA1c in 2022; 51.39% female, mean age 63.90 years, baseline HbA1c 7.72%
- Participants
- 8,867 adults
- Exposure
- Rates of phone and video telemedicine visits vs in-person visits
- Outcome
- Change in HbA1c between baseline and the 2022 assessment
- Follow-up
- 2020 to 2022
Methodological detailsendocrinology clinics at an integrated health system, multivariable regression adjusted for demographic and clinical covariates

Main finding
As reported in the abstract
Change in HbA1c
- Mean HbA1c decrease, whole cohort
- 0.17%
- Higher rates of phone visits associated with a smaller decrease in HbA1c
- P = .009
- Mean share of telemedicine visits in 2021
- 35.09% (25.18% video, 9.91% phone)
Observational data: associations, not effects.
Further findings
Change in HbA1c by baseline HbA1c stratum: phone visit rate · 2020 to 2022
- Baseline HbA1c ≥ 8.0%: higher phone visit rates associated with smaller HbA1c decrease
- P = 0.001
- Baseline HbA1c < 8.0%: no association
