Description of intervention(s) / exposure
This is a 13-week single arm study conducted in the Southern Region of New Zealand. All participants will be involved in the study for 15 weeks (2 weeks of baseline monitoring and 13-week intervention). The main study will be followed by a 39-week extension phase(to a total of 12-months).
The study will enrol 20 participants, aged 16 years and over. Following consent, baseline data will be collected from eligible subjects. Subjects will receive the Care Sens Air continuous glucose monitoring (CGM) system. Following a run-in period of 2 weeks to collect baseline blinded glycaemic values, participants will begin the 13-week intervention phase. The intervention will utilise the CGM data to optimise the NZSSD type 2 diabetes management algorithm, led by the study pharmacist. Participants will continue to wear the Care Sens Air CGM throughout the 13-weeks (replacing the sensor every 14
days).
Participants will visit the study pharmacist at baseline (after blinded CGM), and receive a follow up sessions at week 2, and 8 to help titrate medications in line with guidelines. CGM data will be automatically uploaded to the Sens365 online diabetes management portal via the CareSens Air mobile application. After completion of the main study (13-weeks), participants will be invited into the extension study (up to 12-months) to collect longitudinal data in this population group.
All participants will receive appropriate lifestyle management advice during the intervention as per the local primary care, model of care. Within 7 days of the baseline visit with the pharmacist, participants will also have an initial lifestyle management consultation. This session will be conducted by either a health coach and/or a Pacific provider nurse, and cultural support workers as appropriate and is estimated to take ~30-45 minutes. Topics discussed and goals set during these sessions will be guided by the participants specific requirements/needs as identified by the practitioners. Examples of which may include, but are not limited to: physical activity, sleep, sedentary time, social support, cultural support. They will also see a dietitian. This appointment will also be 30-45 min in duration. As above, topics and goals set during these sessions will be guided by the participants specific requirements/needs as identified by the practitioners. Examples of which may include, but are not limited to: general healthy eating, fibre intake, carbohydrate quality.
Allied health reviews will be offered in a Pacific provider setting at the convenience of the patient, allowing for extended consultations, convenient appointment times and inclusion of family members involved in care. Transport, social services and support in understanding and navigating the health system will also be offered as required. Within a Pacific provider setting, Pacific led diabetes awareness programmes will also be on offer building diabetes awareness and health literacy. Participants will receive remote follow up regarding lifestyle management goals at weeks 2 and 8, with additional appointments scheduled at the discretion of the care team. All participants will be supported by cultural support workers for the duration of the study.

Expected duration of subject participation is a minimum of 14 weeks:
Day -14 Visit: Commence run-in period and baseline data collection (including blinded CGM). During this time participants will continue with current medications and diabetes management.
Day 1 Visit: Appointment with study pharmacist for intervention start and lifestyle management initial consultation with a health coach/pacific provider nurse + cultural support worker + dietitian (may be conducted between days 1-7 depending on practitioner availability).
Week 2 (Day 14) Phone Call: Follow up with study pharmacist + assisted remote upload of data + lifestyle management (health coach)
Week 8 (Day 56) Phone Call: Follow up with study pharmacist+ assisted remote upload of data + lifestyle management (health coach)
Week 13 (Day 91) Visit: Primary end point, repeat baseline measures and qualitative interviews

After completion of the main study, participants will be invited into the 13-week extension phase study.:
Week 17 remote follow up by health coach and/or cultural support worker
Week 21 remote follow up by health coach and/or cultural support worker
Week 26 (Day 182) Visit: Repeat baseline measures + lifestyle management (health coach)
Week 36 (Day 252) Visit: Repeat baseline measures + lifestyle management (health coach)
Week 52 (Day 365) Visit: Extension study completion, repeat baseline measures.

Note: Attendance at sessions will be recorded in the study CRFs. Remote reviews will be conducted via phone and/or video calling. Lifestyle management will be guided by previous sessions whereby exisiting goals may continue to be supported and new goals may be developed if indicated.
