Objective: We compared treatment satisfaction with a tubeless insulin pump (Omnipod DASH® Insulin Management System) to usual care (multiple daily injections [MDI] or tubed insulin pump therapy [IPT]) in adults with type 1 diabetes using self-monitoring blood glucose (SMBG).
Research design and methods: Adults with type 1 diabetes on MDI (n = 40) or IPT (n = 25) from four diabetes centers in Australia were randomized in a 1:1 non-blinded manner to Omnipod DASH System (Omnipod group) or continue usual care (Usual Care group) for 12 weeks, followed by a further 12-week extension where all participants used the device. The primary outcome was treatment satisfaction assessed by change in Diabetes Technology Questionnaire 'current' (ΔDTQ-current) score at 12-weeks (study-end). Secondary outcomes included ΔDTQ-current following extension and other participant-reported outcomes (PROs) measuring quality of life, burden of disease treatment, glycemic and device-related outcomes at 12-weeks (study-end) and 24-weeks (end-extension).
Results: Treatment satisfaction improved more in Omnipod group vs. Usual Care group (ΔDTQ-current score of 16.4 [21.2] vs. 0.0 [12.8]; p < 0.001) at study-end. Significantly greater improvements in other PROs and HbA1c were also observed. Improvements in DTQ-current and other PROs comparing study-end and end-extension were similar. While %TIR change from baseline did not differ at study-end (-2.0 [12.7] %), it was significantly greater at end-extension (5.6 [10.9] %; p = 0.016).
Conclusions: Omnipod DASH System resulted in greater treatment satisfaction at 12 weeks in adults with type 1 diabetes using SMBG which was sustained after 24 weeks of device use without compromising sleep quality and fear of hypoglycemia. Improvements in glycemia were also observed.
