Retrospective Analysis of the Pharmaco-Utilization of VEGF Inhibitors and Health Care Costs among Patients with Wet Age-Related Macular Degeneration and Other Ocular Diseases in Italy

This Italian retrospective study aimed to analyze the pharmaco-utilization of anti-VEGF drugs and health care costs among patients with wet age-related macular degeneration (wAMD) or other ocular diseases. A retrospective analysis was performed on administrative databases of Italian entities covering approximately six million individuals. Across January 2010-December 2017, patients aged ≥50 years with a prescription of intravitreal anti-VEGFs were included as "wAMD" patients [by wAMD hospitalization or intravitreal injections] or as "other ocular diseases" patients [by hospitalization for other ocular disorders or intravitreal injections, with concomitant diabetes diagnosis or dexamethasone treatment]. The date of first matching of inclusion criteria was index-date. wAMD-cohort. Overall, 3879 patients were included; at index-date, 82.2% were treated with Ranibizumab, 15.8% with Aflibercept, and 2% with Pegaptanib. During the follow-up, the mean/annual anti-VEGF prescription [3.6 (first-year)-0.8 (third-year)] and the total expenditure [5799.84 € (first-year)-3212.84 € (third-year)] decreased. Other ocular diseases-cohort. Overall, 2646 patients were enclosed; 85.9% were treated with Ranibizumab, 13.5% with Aflibercept, and 0.6% with Pegaptanib. During the follow-up, the mean/annual anti-VEGF prescription [3.3 (first-year)-0.5 (third-year)] and the total cost [7196.83 € (first-year)-5162.68 € (third-year)] decreased. This observational study highlighted a decline in anti-VEGF prescriptions over time in both cohorts, suggesting a trend of under-treatment that could worsen the patients' clinical outcomes and increase health care resource consumption.
