Implementing diabetic retinopathy screening using in-clinic retinal photographs and automated software analysis increases screening rates for diabetic retinopathy among low-income minority patients

One-third of diabetic adults in the U.S. do not receive annual eye exams. Additionally, lack of pupillary dilation before exams is associated with ungradable, or insufficient exams. In September 2022, the OhioHealth Grant Medical Center Family Medicine practice implemented on-site diabetic retinopathy screening using digital fundus photography and automated retinal imaging without dilation. The practice later introduced eye dilation for specific patients.

By identifying patients needing screening before appointments and using electronic health record reminders, the clinic increased the rate of interpretable exams from 20% in November 2022 to 35% in May 2023. That same month, the clinic began offering eye dilation to patients over 64 years of age and those who failed non-dilated exams. This change reduced the insufficient exam rate from 36% to 22% over the following eight months. The clinic’s retinopathy detection rate increased from 11% to 18% between September 2022 and January 2024. By January 2024, the screening rate was 57% for patients not seen in a year and 65% for those seen within the year. 

The greatest increase in retinopathy screening came after clinic managers started tracking patients who needed screening prior to their appointments, and reminding staff through the electronic health record to perform screening. Offering dilated eye exams further reduced the rate of insufficient exams. Overall, the strategy of using in-clinic retinal photographs with software interpretation and selective eye dilation effectively increased screening rates for our patients from socially disadvantaged populations.
