Background:Studies have shown that teleophthalmology programs using a nonmydriatic camera in primary care settings can improve rates of diabetic retinopathy (DR) screening. However, such programs are not yet widespread due to common challenges in sustainability.Purpose:To comprehensively evaluate clinical and operational measures of an urban primary care clinic's 1-year pilot teleophthalmology DR evaluation program.Materials and Methods:This retrospective analysis used five metrics to evaluate the program: clinical diabetic retinal exam (DRE) rate, visual acuity and pathology, camera utilization, billing and insurance reimbursements, and outcomes of follow-up referrals.Results:Two hundred eleven patients were screened over 14 months. The DRE rate had more than doubled (34-75%). Of the patients, 55.9% had vision better than 20/50 in each eye and 21% with at least 1 eye worse than or equal to 20/70. DR was noted in 11% of patients. The program's first few months saw greatest camera use. Government and Medicare Advantage insurers were significantly (p < 0.001) less likely to reimburse than commercial insurers. Twenty-seven percent of patients screened had documented follow-up with an eye care provider within 16 months of their screening. Patients diagnosed with DR or recommended follow-up within 1 month were significantly (p < 0.001) more likely to schedule an appointment.Discussion:Challenges to program sustainability include efficient utilization, reimbursement from governmental insurers, and adherence to follow-up recommendations.Conclusions:Assessing teleophthalmology programs with the aforementioned five metrics allows for a comprehensive evaluation of impact and sustainability. This may be utilized to standardize the implementation and evaluation of such programs across diverse settings.
