The characteristics of the patients who received remote screening were compared with those patients who were eligible for screening but did not take part in the program. Time-driven activity-based costing (TDABC) was implemented to examine the cost of screening by tele-ophthalmology compared with in-person examinations.Results: Tele-ophthalmology screening was more likely to be provided for patients who were younger (OR 0.985; 95% CI 0.973– 0.997, p=0.016), who were obese (OR 2.04; 95% CI: 1.47– 2.84, p=0.008), who had an HbA1c above 8.0% (OR 1.60; 95% CI: 1.13– 2.26, p=0.031), or who had an eye examination in the past year (OR 5.55; 95% CI: 3.89– 7.92, p< 0.001). Those patients newly diagnosed with DR because of the program were more likely to have diabetic nephropathy (OR 7.79; 95% CI: 1.73– 35.05, p=0.007). TDABC identified a health system cost-savings of between $8 and $29 per patient screened by tele-ophthalmology compared with the cost of in-person eye examinations.Conclusion: Tele-ophthalmology presents an opportunity to reduce the costs of screening patients without prior evidence of DR, especially those who have completed a comprehensive eye examination within the prior year.Keywords: telemedicine, tele-ophthalmology, diabetes, diabetic retinopathy, screening, non-mydriatic fundus photography
