Table 1 Workshop objectives, activities and post workshop activities

Month 1:

Patients in the community co-development workshop 1

2 (1in Mandarin, 1 in French)

Project Step 2—Building of personas of individuals who require diabetic retinopathy screening

Developed 3–4 personas using Nominal Group Technique (NGT)

Data Type: Personas

Research team and patient partners prepared cards containing barriers/enablers to DRS based on personas

Month 2: Patients in the community co-development workshop 2

2 (1in Mandarin, 1 in French)

Project Step 3 – Identifying and prioritizing barriers/enablers for attending tele-retinopathy screening

Generated and prioritized barriers/enablers to attending screening based on personas using NGT

Data type: Ranking of barriers/enablers

Research team and patient partners mapped literature based BCTs to prioritized barriers/enablers using meta-analytic evidence from Cochrane review

Month 3: Patients in the community co-development workshop 3

2 (1in Mandarin, 1 in French)

Project Step 4 – Prioritizing and operationalizing solutions to barriers/enablers

Using NGT, brainstormed, discussed, prioritized, and described how each persona could receive the strategies

Data Type: Ranking of Strategies

Research team developed a draft intervention to inform workshop discussions with health system partners and prototyping resources

Month 4: Health system partner co-development workshop 1

1

Project Step 5 – Anticipate delivery barriers to inform further patient partner co-development

Using the Action, Actor, Context, Target, Time – (AACTT) framework, described who would need to do what differently to enact the intervention

Data Type: Workshop notes

Research team, patient, and health system partners, developed draft resources to operationalize the prioritized strategies, emphasizing content and clarity

Month 5–8: Patient partner co-development workshop

4 (4 for each group)

Project Step 6 – Optimize intervention content

Using NGT, shared suggestions for optimizing the content of resources and the care pathway for the intervention

Data Type: Workshop Notes

The research team summarized the intervention process and optimized resources

Month 9: Health system partner co-development workshop 2

1

Project Step 7 –Optimize delivery

Using AACTT and TDF, clarified any remaining anticipated barriers and developed implementation solutions to address them

Data Type: Workshop Notes

The research team produced the working version of the tele-retinopathy screening intervention
