Research Summary
Telemedicine improves glucose control in nursing home residents with diabetes.
Moderate confidence
Low bias
Last updated July 8, 2026Key Takeaway:
This study evaluated the impact of remote insulin dose adjustment using continuous glucose monitoring (CGM) on glucose control in nursing home residents with type 2 diabetes (T2D). The intervention group showed significant improvements in glucose metrics compared to standard care.

Main Effects
TIR increased by 10.3% in the intervention group (p = 0.010).
TBR decreased by 3.1% in the intervention group (p = 0.007).
HbA1c decreased by 9 mmol/mol in the intervention group (p = 0.028).
Mean daily insulin units decreased by 3 IU/day in the intervention group (p = 0.002).

Evidence Suggest
- Telemedicine-assisted insulin titration improved TIR by 10.3%.
- Intervention group showed a 3.1% reduction in TBR.
- HbA1c levels decreased by 9 mmol/mol in the intervention group.
Who this applies to
- Nursing home residents with type 2 diabetes.
- Patients on basal-bolus insulin therapy.
- Elderly individuals requiring insulin management.
Keep in Mind
- Results may not apply to younger populations or those outside nursing homes.
- The study focused on a specific insulin regimen, limiting broader applicability.
- Further research is needed to confirm long-term benefits of remote monitoring.
Between the Lines
- Limited generalizability due to specific population (nursing home residents).
- Potential biases in self-reported data.
- Short duration of the study may not capture long-term effects.
