Abstract
Introduction Intravitreal (IVT) injections of anti-vascular endothelial growth factor (VEGF) agents are the standard of care for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME). While demonstrated to be effective, these treatments potentially place a significant burden on patients owing to their cost and frequency of treatment visits required for administration. The objective of this study was to investigate the economic burden of treatment on patients with nAMD/DME and their informal caregivers in seven countries. Methods Data were collected from patients and caregivers in the USA, UK, Canada, Italy, Spain, Germany, and France using a survey between September and December 2022. Each survey collected data to facilitate calculating economic burden, combining the total financial costs (i.e., direct costs to receive treatment) and productivity losses associated with attending treatment appointments over a 6-month period. Quality of life data were collected using validated instruments. Results In total, 194 patients and 194 caregivers reported currently receiving (or caring for someone who receives) anti-VEGF treatment. Across all countries, the modal frequency of anti-VEGF treatment was every 4 weeks, except for patients with DME (every 8 weeks). The largest, mean 6-month economic burden on the pooled population of patients with nAMD/DME was reported in Italy (€1244) and on caregivers it was in the USA (€3069). Economic burden was lower for respondents receiving fewer anti-VEGF injections. Conclusions More durable therapies for nAMD/DME would reduce treatment burden and have a sizeable impact financially on patients with nAMD/DME and their caregivers.
