Description of intervention(s) / exposure
Omnipod 5 is a current generation Automated Insulin Delivery (AID) enabled tubeless insulin pump.
The aim is to conduct a randomised controlled study comparing the user experience with Omnipod 5 and ‘usual care’ in people living with Type 1 Diabetes (T1D).
Seventy-four adults with a diagnosis of type 1 diabetes managed with MDI or Insulin Pump Therapy (IPT) will be recruited from five tertiary hospitals in Victoria and South Australia for a total duration of 26 weeks.

The study has the following phases:
1. Screening Period: the study doctor will explain to the participant what the study involves and the participant will have time to read the Participant. Information Sheet and Consent Form and ask any questions. If they agree to participate in the study they will undergo medical history, physical examination and investigational tests.

2. Run-in period (14 days): participants will be provided with a wrist-worn actigraphy device to wear for the 14 days and complete daily sleep and physical activity diaries for the 14 days.

3. Treatment period (24 weeks): all participants will be randomly allocated to 24 weeks of either continuing their usual care (MDI or IPT, with general diabetes education) or commencing on the Omnipod 5 insulin pump (with relevant education provided in person by the study doctor and nurse who have training in Omnipod 5). The education will be provided immediately after random allocation for 30 minutes. This review will be in person in the clinical trials centre but future reviews may be over the phone or in person.

During the treatment period advice and supervision for the management of T1D will be provided whether the participant is in the usual care or Omnipod 5 group. For the Omnipod 5 group a supervised in person pod change will occur 3 days after randomisation.

For both groups all participants will have remote phone calls during weeks 1, 2, 3, 4, 8 for safety monitoring and review of device data which participants will be required to upload. Participants will also have in person clinical monitoring visits in the clinical trials centre in week 10, 12, 22, and 24 which will include device data review and administration of questionnaires.

4. Optional Extension period (12 weeks): participants allocated to usual care will have the option of a 3 month extension where they will be able to trial Omnipod 5 and questionnaires will be completed at the conclusion of this. These questionnaires will be included in the data analysis.
