An analysis of Medtronic MiniMed 670G insulin pump use in clinical practice and the impact on glycemic control, quality of life, and compliance

Aims: This study evaluated the use of the Medtronic MiniMed 670G system in adults with type 1 diabetes mellitus from a large endocrinology practice and its impact on glycemic control, quality of life (QoL), compliance and safety.

Methods: 84 participants completed one site visit for data collection. Percentage of time in range (TIR: 70-180 mg/dL), hyperglycemia or time above range (TAB) (>180 mg/dL), hypoglycemia or time below range (TBR) (<70 mg/dL), HbA1c, average blood glucose (ABG), and other metrics were evaluated at the last visit using the system (LVMM) and compared between the last visit on previous insulin therapy (LVPT).

Results: The mean percentage of TIR at the LVMM was 74.0 ± 12.1%, with an increase of 27.1% (p < 0.001) in TIR from the LVPT. The mean percentage of TAR was 22.9 ± 11.8% and the mean percentage of TBR was 3.2 ± 5.1%.

Conclusions: The use of the Medtronic MiniMed 670G system in our practice resulted in a TIR above the recommended target with a high degree of treatment satisfaction and compliance in adults with type 1 diabetes. Furthermore, the system may be a reasonable choice for patients struggling with significant amounts of hypoglycemia.
