Background and objective: This study characterizes the impact of race, ethnicity, insurance status, and geographic location on anti-vascular endothelial growth factor (VEGF) use for the treatment of diabetic macular edema (DME).
Patients and methods: This study is a retrospective cohort study. The American Academy of Ophthalmology Intelligent Research in Sight Registry was queried for patients diagnosed with DME who received at least one anti-VEGF injection between 2012 and 2020 (n = 203,707). Multivariate regression analyses investigated associations between race, ethnicity, insurance status, and geographic location and anti-VEGF use and visual outcomes.
Results: White race, non-Hispanic/Latino ethnicity, and private insurance were associated with higher use of anti-VEGF injections during a 60-month period (incidence rate ratio, 1.2, 1.25, and 1.17, respectively; P < .01). Furthermore, being of non-Hispanic/Latino ethnicity and having private health insurance were associated with higher longitudinal visual acuity (odds ratio, 1.44 [P = .02] and odds ratio, 1.43 [P < .01], respectively).
Conclusion: Ethnicity and insurance status are associated with anti-VEGF use and visual acuity outcomes in DME. [Ophthalmic Surg Lasers Imaging Retina 2022; 53:380-391.].
