Increasing Diabetic Retinopathy Screening

Study Description

Increasing DR Screening Through TOP: Supporting Implementation and Identifying Opportunities for Scale up in Ontario

It is recommended that people with diabetes have their eyes screened for retinopathy every 1-2 years. Retinopathy can lead to visual impairment and blindness, but early detection through regular retinal screening can help to prevent this. Many Ontarians with diabetes have not been receiving regular screening. One possible way to get more people screened for retinopathy involves tele-retinal screening using teleophthalmology (TOP), where patients can have their eyes screened in their local clinic or a site nearby. In this project, we are testing 3 patient interventions: mailing a letter, phone call or an option to bundle their screening with other diabetic care services (e.g. foot care exam) and examine the impact of these various interventions alone or in combination with each other.

a mail letter, a phone call and a phone call plus mailed letter

All patients will be administered an intervention that will contain one or more of 3 possible interventions (a mail letter, a phone call and a mail plus phone call). Some patients will also be assigned into a condition where none of the interventions will be present. Patients at Black Creek CHC will only be offered a phone or a phone plus incentive intervention or a no intervention.
