Background and aims: Intensified insulin therapy for type 1 diabetes (T1D) can be administered by multiple daily injection therapy (MDI) or continuous subcutaneous insulin infusion therapy (CSII) . Despite the clinical benefits of CSII, its therapeutic implementation rate remains low. Thus, this study aims to evaluate the change in treatment satisfaction and metabolic changes of people with T1D switching from MDI to CSII therapy using a novel modular patch pump system.

Materials and Methods: A total of 50 adults from Argentina with T1D, naïve to CSII, were enrolled in a multi - center, prospective, single - armed study for the Accu-Chek® Solo micropump system (ACS) . Change in diabetes treatment satisfaction after 13 weeks (mean 106, min 83, max 176 days) was assessed by the “Impact and Satisfaction” section of the Diabetes Technology Questionnaire (DTQ) as the primary outcome. In addition, changes in the HbA1c were reported by the investigator as a secondary outcome.

Results: The mean DTQ “now” score improved from 92.96 ± 14.98 to 103.15 ± 19.47 (p = 0.0166) and the “change” score, as the primary outcome, was 113.24 ± 17.50 (p < 0.0001) . Based on pre - defined sub - categories, the following mean DTQ scores were measured: 3.83 ± 0.62 for “diabetes distress and burden,” 3.98 ± 0.70 for “hypoglycemia fear, worry and behavior,” 3.59 ± 0.70 for “device acceptance and satisfaction,” 3.92 ± 0.61 for “other.” In addition, the mean HbA1c, as a secondary outcome, decreased from 8.19 % ± 1.36 to 7.83 % ± 1.23 (- 0.37 %pt, p = 0.0148) . Thereby, the HbA1c reduction was not associated with any reported incidents of hypoglycemia.

Conclusion: The switch from MDI to the Accu-Chek® Solo micropump system led to a significant improvement of subjects’ treatment satisfaction after 13 weeks, which was linked to a significant reduction of the outcome HbA1c without any reported incidents of hypoglycemia.
