Caregiver Experience Survey of Anti-Vascular Endothelial Growth Factor Treatment for Diabetic Macular Edema and Neovascular Age-Related Macular Degeneration.

Diabetic macular edema (DME) and neovascular age-related macular degeneration (nAMD) require frequent treatment/monitoring visits. We aimed to understand the burden of treatment on caregivers. This multinational, noninterventional study used a cross-sectional survey of adult patients with DME or nAMD treated with anti-vascular endothelial growth factor injections in the United States, Canada, France, Italy, Spain and the United Kingdom. The survey assessed caregivers' sociodemographic characteristics, patient relationships, patients' clinical history and treatment experiences, caregivers' experiences, and the Caregiver Reaction Assessment of caregiving burden. Caregivers for patients with DME (n = 30) and nAMD (n = 95) completed surveys. Mean ± standard deviation (SD) age was 64.0 ± 13.4 years, and most were female (71.2%), White (70.4%), married (66.4%), and from Europe (67.2%). Most were caring for their mother/father or partner/spouse (85.6%). Mean ± SD length of time as a caregiver was 9.1 ± 10.0 years. Caregivers estimated they provided support for 4.2 ± 2.9 days/week and 6.0 ± 7.1 hours/day on average. Nearly half of caregivers (45.6%) reported some impairment in daily activities, and more than two-thirds (70.5%) of working caregivers (n = 44) reported work absenteeism due to treatment/monitoring appointments. At least one treatment barrier was reported by 66.7% and 50.5% of caregivers of patients with DME and nAMD, respectively, which were related to coronavirus disease 2019- (38.4%), clinic- (18.4%), social-/health- (13.6%), treatment- (10.4%), or financial-related factors (4.8%). Caregiver Reaction Assessment scores indicated mild-to-moderate burden, with higher caregiver schedule disruption scores associated with an increasing number of treatment/monitoring visits among DME caregivers (r = 0.61). Caregivers devote substantial time to caregiving, leading to schedule disruptions and absenteeism for some working caregivers. Positive and negative impacts on caregiver mental health were reported.
