Description of intervention(s) / exposure
Diabetic retinopathy Screening
a) any physical or informational materials used,
Consenting participants will be given a copy of the ethics approved plain language statement. Participants will also be shown digital images of their eyes to discuss retinopathy and facilitate education about related complications of diabetes. To further assist with diabetes education, educational tools such as Feltman (life-size wall hanging) and HbA1c risk-gradient card will be used.
b) each of the procedures, activities, and/or processes used,
The following procedures and activities will be undertaken at baseline and final visits:
1) Measuring and recording of presenting vision and, if this is < 6/12, pinhole vision as well.
2) Diabetic retinopathy imaging will be undertaken. Protocol will consist of 3 images per eye. [disc-centred, macular-centred and an exterior eye image]. Captured images will be sent to an external ophthalmic clinician or certified grader for retinopathy grading and follow-up recommendations based on NHMRC guidelines for management of diabetic retinopathy (2008).
3) Diabetes education will be provided based on standard diabetes education, retinal fundus images and Indigenous pedagogy
4) Ethics approved surveys will be administered. These are Diabetes Knowledge, SNAPE (smoking, nutrition, alcohol, physical activity & emotional wellbeing) and Vision Impairment surveys. At the final visit, a diabetes care satisfaction survey will also be administered.
c) who will deliver the intervention,
Intervention will be delivered by an Indigenous credentialled diabetes educator and registered nurse who is also an experienced and certified retinal imager.
d) the mode of delivery,
Mode of delivery will be by face-to-face individual consultation
e) the number of times the intervention will be delivered and over what period of time,
The intervention will be delivered twice, the first time being the baseline visit and the second being 12 months later, or sooner based on initial grading report recommendations for followup.
f) the location where the intervention occurs.
Intervention will occur at partner Aboriginal Community-Controlled Health Service primary care clinics in regional Victoria, the first being Rumbalara Aboriginal Cooperative – Health Service

Outcomes
Primary outcome [1]
306471
0
Percentage returning for recommended eye screening as per initial grading report recommendations [based on NHMRC guidelines for the management of diabetic retinopathy (2008)]. For example, in the subset without retinopathy, the % returning for diabetic retinopathy screening within 12 months of baseline eye screening.
Eye screening data will be collected from the laptop specific program that automatically captures and stores the retinal images. Each set of images are identified patient identification number, name, age and sex. Data specifically relating to patient adherence to NHMRC eye screening recommendations (when they last seen the optometrist) will be extracted from their electronic health records (Commuicare) and for verification, patient will be asked when/and if they have had a comprehensive eye exam in the last 12 months

- Smoking status
- Diet quality
- Alcohol consumption
- Physical activity level
- Adapted PHQ9
An adverse event potential exists where an individual records a high score on the adapted PHQ9 survey. If a participant’s score is great than 20 on the adapted PHQ9 survey, the participant will be accompanied by the research nurse to a doctor for emergency mental health assessment and management.

Statistical methods / analysis
The researchers will conduct data analyses using Excel and SPSS software. Analyses using descriptive statistics and uni-variate analyses (test for continuous and Chi-squared for categorical variables) will provide key descriptive data, such as prevalence rates and lifestyle data, proportion treated to target for DR risk factors and predictors of DR, vision outcomes and qualitative survey data.
Site differences will be analysed. Analysis of covariance (ANCOVA) will be used to compare differences between groups. To assess confounding, covariates will include age, gender, and established and emerging risk factors for diabetes and DR, as appropriate. Non-parametric statistics will be used when assumptions for parametric methods are violated. All tests will be conducted using an alpha level of
0.05 and 95% confidence intervals or interquartile ranges, as appropriate, will be reported.

Summary
Brief summary
Diabetic retinopathy is a major public health problem in Australia, particularly among Indigenous Australians. For this reason, national guidelines in Australia were first developed for diabetic retinopathy. Despite efforts over two decades aimed at timely detection and early treatment of diabetic retinopathy, about half the Indigenous population with diabetes in Australia is not screened in accordance with the guidelines. Novel approaches to screening for diabetic retinopathy are needed, particularly in Australia's remote, under-resourced and Indigenous communities.The aim of this project is to implement an imaging-based telehealth diabetic retinopathy screening program managed by a diabetes educator in Indigenous primary care clinics. Objectives 1) To develop a model of integrated DE and DRS assessment in regional Indigenous primary care services. 2) To develop culturally-informed DE and DRS programs with input from Indigenous stakeholders. 3) To improve DRS coverage in Indigenous primary health care services. 4) Use DRS images and vision status to reinforce importance of diabetes self-management for reducing risk of all diabetes complications. 5) Facilitate timely referral pathways to ophthalmic services and diabetes specialist services. Research Design Proof of concept trial using a qualitative and quantitative approach. Up to three rural/regional trial-sites and approximately 250 T2DM participants aged older than 18 years of age Pre-post trial design: diabetic retinopathy screening, assessing health literacy, clinical and lifestyle risk factors, social/emotional well-being, satisfaction with diabetes education, perceived barriers/motivators to access and follow-up services. Baseline visit: Diabetic retinopathy screening, Smoking, Nutrition, Alcohol, Physical (activity) and Emotional (well-being) [SNAPE] and Vision Impairment Questionnaires to will be administered. HbA1c, lipids and blood pressure will also be measured to gauge patient’s baseline diabetes self-management. Surveys will assess a patient’s diabetes knowledge and health literacy, Final visit: Diabetic retinopathy screening repeated to assess adherence to annual screening recommendation, administration of the Diabetes Knowledge Questionnaire to gauge if patient’s diabetes knowledge has increased and self-care has improved over the intervention period, repeat measurement of patient’s HbA1c, lipids and blood pressure to see if diabetes risk factor control has improved. Patients will also have administered the Diabetes Treatment Satisfaction Questionnaire that will gauge patient’s satisfaction with the intervention over time. With integration of diabetes education and diabetic retinopathy screening, it is expected that engagement with self-management [risk factor control and adherence to retinopathy screening recommendations] will improve.
