Comparing Equil patch versus traditional catheter insulin pump in type 2 diabetes using continuous glucose monitoring metrics and profiles

Abstract

Abstract Aims It is not clear whether there are differences in glycemic control between the Equil patch and the MMT‐712 insulin pump. Our objective was to compare two types of insulin pumps in the treatment of type 2 diabetes mellitus (T2DM), using continuous glucose monitoring (CGM) metrics and profiles. Methods This was a randomized case‐crossover clinical trial. Participants were hospitalized and randomly allocated to two groups and underwent two types of insulin pump treatments (group A: Equil patch—Medtronic MMT‐712 insulin pump; group B: Medtronic MMT‐712—Equil patch insulin pump) separated by a 1‐day washout period. Glycemic control was achieved after 7–8 days of insulin pump therapy. Each patient received CGM for 5 consecutive days (from day 1 to day 5). On day 3 of CGM performance, the Equil patch insulin pump treatment was switched to Medtronic MMT‐712 insulin pump treatment at the same basal and bolus insulin doses or vice versa. CGM metrics and profiles including glycemic variability (GV), time in range (TIR, 3.9–10.0 mmol/L), time below range (TBR, 10.0 mmol/L), and postprandial glucose excursions, as well as incidence of hypoglycemia. Results Forty‐six T2DM patients completed the study. There was no significant difference in parameters of daily GV and postprandial glucose excursions between the Equil patch insulin pump treatment and the Medtronic insulin pump treatment. Similarly, there was no between‐treatment difference in TIR, TBR, and TAR, as well as the incidence of hypoglycemia. Conclusion The Equil patch insulin pump was similar to the traditional MMT‐712 insulin pump in terms of glycemic control. Equil patch insulin pump is a reliable tool for glycemic management of diabetes mellitus.
