Interventional
Description of intervention(s) / exposure
Participants in this group will receive usual care, plus the Wear-IT intervention. Those attending the usual care practices will receive standard care. An 8-week self-management care plan, incorporating wearable devices, will be provided to patients in the intervention group. Outcomes will be assessed 6- and 12-months post-randomisation.

The program will include:

Initial Consultation (Care plan and goal setting through CareMonitor). Practice nurses will invite consenting patients to attend a face-to-face 45 minute consultation following practice randomisation and intervention training. Patients will work with their care team to develop a care plan using CareMonitor, including individualised target ranges for diet, exercise, Body Mass Index, Cigarette consumption, alcohol consumption, HbA1c, lipids and blood pressure. This will enable patients to monitor their own targets and behaviours through their wearable devices. The following will be tracked using wearable devices:
• Physical activity and exercise: Individual patient activity goals may include reducing sedentary behaviour and increasing anaerobic or resistance exercise, in line with best-evidence guidelines. Patients will be able to access daily and weekly summaries of their physical activity and exercise goal progress.
• Dietary intake: Over a two-week period, the flash glucometer will provide real-time feedback to patients on their blood glucose levels including post-prandial elevation. Patients will be prompted to consider the dietary cause of the variation to their blood glucose and provided with strategies to reduce the likelihood of this occurring again. Blood glucose can be monitored via daily or weekly summaries and as time in target blood glucose range.
• Blood pressure: Periodic monitoring of blood pressure will enable the care team to assess blood pressure control and response leading up to an appointment or after a change in therapy. Patients with elevated blood pressure during periodic monitoring will be prompted to consult their care plan within CareMonitor and ensure they are adhering to their therapeutic and medication recommendations.

The practice nurse will guide patients in downloading and using the CareMonitor app via their smartphone, tablet or smart device. Patients will be supported by the practice nurse to link the CareMonitor app with the wearables provided for the study and demonstrate their use. Provided wearables will include: (i) a physical activity monitor to track physical activity; (ii) a glucose monitor to periodically track blood glucose levels; and (iii) a blood pressure monitor to periodically track blood pressure. While some patients may already use a physical activity monitor, they will be encouraged to wear the study-provided monitor to standardise data. The practice nurse will help the patient set evidence-based individual activity and treatment goals, which will be reviewed and endorsed by the GP.

Weeks 1-4 (Remote patient intervention). The intervention wearable devices will be used in combination to deliver a comprehensive assessment of health behaviour and diabetes control over a period of 4 weeks.
• Patients will be asked to commence wearing their physical activity monitor immediately and throughout the 4-week period. Patients will be encouraged to monitor physical activity continuously over the intervention period and will access daily and/or weekly summaries to assess if they are meeting their goals.
• Patients will be asked to commence blood pressure monitoring on day 5 of the intervention period and be asked to record it in the morning and evening for 7 continuous days as per Heart Foundation advice on home blood pressure monitoring
• Patients will be asked to commence their continuous blood glucose monitoring at the start of week 3 for a 2-week period. The blood glucose device sits on top of the skin and continuously monitors glucose levels. These devices are disposable, expiring after 2 weeks of use.
• Patients will be periodically prompted to watch brief educational videos about managing their diabetes (e.g., “Importance of blood pressure and diabetes”). These videos were designed by Western Sydney Diabetes (study partners) and repurposed for the study. They are not a readily available resource.

Follow-up Consultation (Review and update of care plan if needed). The patient will be invited to return for a 30 minute with the practice nurse, and review by their GP. This consultation will involve reviewing the patient’s data from their wearable devices and assess whether they have been meeting their care goals. Goals will be updated as needed to assist patients in achieving these. The care team will discuss potential ways to improve their physical activity, glucose levels and blood pressure. This may include a medication review if considered necessary by their GP.

Weeks 5-8 (Remote patient intervention). The patient will repeat the intervention as per weeks 1-4, with the implemented changes as discussed in their follow-up consultation. Patients will be able to see how these changes impact their wearable outputs. Patients will be informed they can book a 30 minute follow-up appointment with their care team if they have further questions about the changes to their care plan.

Efficacy
Statistical methods / analysis
The analysis will follow intention to treat principles, where patients will be analysed according to the practice they were attending at randomisation, and missing data will be imputed using multiple imputation methods. The intention to treat population will include all patients with a type 2 diabetes diagnosis who were active patients in the baseline or follow-up period. Baseline characteristics will be summarised between the groups using means and standard deviations for continuous variables and frequencies/counts for categorical variables. The primary outcome variable (mean % HbA1c level) will be measured at 6- and 12-months post-randomisation. The difference between intervention arms will be assessed using linear mixed effects regression models. Regression models will incorporate random effects for practices, GPs nested within practices, patients nested within GPs (for repeated measures on the same patient), as well as fixed effects for the practice level mean baseline value of the outcome and treatment group and stratification variables. The same model will be used to assess differences in the continuous secondary outcome variables (i.e., macro-vascular risk and quality of life). A transformation will be applied if the distributional assumptions are not met.

Summary
Brief summary
The prevalence of diabetes is increasing in Australia. Lifestyle behaviours and patient self-management are crucial for improving diabetes control but are difficult to achieve in primary care. While an integrated digital care may be effective, there is limited research. Primary aim: The study will examine the effectiveness and cost-effectiveness of the multi-component Wear-IT intervention in achieving clinically significant reductions in HbA1c among general practice patients.

A cluster randomised controlled design will be used with general practice clinics randomly assigned to either intervention (n=15) or usual care (n=15). Twenty patients will be recruited from each clinic. Patients will be eligible to participate if they were aged 18-75 years; had poorly controlled diabetes (i.e., most recent HbA1c greater than 7.5%); and were able to access the online application via an iOS or Android smart device. Those attending the usual care practices will receive standard care. A new model of care consisting of patient self-management digital support (i.e., wearable device, education, and glucose monitoring) approach and clinician management digital support (delivered by the practice nurse with review and endorsement of goals by the patient's GP) will be provided to the intervention group.

Outcomes at baseline, 6- and-12-months follow- up include HbA1c (primary outcome), macro vascular risk (LDL-C less than 2.0mmol/L and a blood pressure reading of =140/90 mmHg), quality of life (36-item short form version 2)) and cost-effectiveness (quality-adjusted life years derived from SF-36). Healthcare utilization will be examined via PenCS medical report. Participants will complete a survey at 6- and 12-months, including sociodemographic characteristics, health risk behaviours, patient knowledge, skill and confidence for diabetes self-management (process measures). Intervention participants will also complete a 6-and-12 month survey about the ease of use, relevance, and quality of the intervention (feasibility and acceptability). GP and practice nurses views about their experience with utilising and delivering the intervention will be assessed by a brief survey and qualitative interviews. The primary analysis population will be the intention to treat, defined as all randomised participants. The secondary outcome variables will be compared between treatment arms using separate linear mixed effects regression models. Inductive thematic analysis will be used to analysis qualitative data.

This study has the potential to improve self-management of diabetes among those with poorly controlled type 2 diabetes. This novel integrated process will empower patients with self-care knowledge and management of diabetes.
