Aims/Introduction:
To evaluate the real-world efficacy of sensor-augmented pump (SAP) for long-term glycemic control and glycemic variability indices.
Materials And Methods:
This was a single-center, retrospective, observational study that included individuals with type 1 diabetes who switched from multiple daily injections to SAP or continuous subcutaneous insulin infusion (CSII). Changes in HbA1c and body weight up to 3 years were compared between the two groups. Changes in the proportion of participants in each group were also analyzed. In the SAP group, changes in continuous glucose monitoring (CGM) metrics were also examined.
Results:
There were 32 individuals in the SAP group and 39 in the CSII group. HbA1c decreased significantly in both groups at 1 year compared with the pre-introduction levels and was maintained for 3 years (- 0.83 ± 0.26%, p = 0.009, and - 0.86 ± 0.18%, p < 0.001, respectively); however, no significant differences were observed between the two groups after 3 years. Body weight increased significantly in the CSII group after 3 years (2.7 ± 0.9 kg in the SAP group, 2.7 ± 3.3 kg in the CSII group. No significant changes were observed in the CGM metrics.
Conclusions:
In individuals who started SAP or CSII, HbA1c decreased after 1 year and was maintained for 3 years.
