ABSTRACT
Objectives: Intravitreal anti-vascular endothelial growth factor (VEGF) therapy is efficacious for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME). However, the frequent treatment and monitoring required for optimal real-world outcomes can be burdensome to patients and can impact adherence to treatment. This study aimed to understand patient treatment experience with anti-VEGF standard of care. Method(s): A cross-sectional survey was employed comprising de novo questions, patient-reported outcome (PRO) measures and medical chart extraction. Adult patients with nAMD or DME treated with intravitreal anti-VEGF injections for >=12 months were recruited via 38 clinical sites (6 Canada, 6 France, 4 Italy, 7 Spain, 6 United Kingdom, 9 United States). Result(s): Surveys were completed by 391 patients with nAMD and 183 patients with DME. PRO scores indicated that patients across both conditions had relatively high vision-related functioning and were generally satisfied with their current treatment. Mean number of anti-VEGF injections over 12 months across countries ranged from 6.3-9.7 for nAMD and 4.3-8.0 for DME. Nineteen patients with nAMD (19/391;5%) and 27 patients with DME (27/183;15%) missed >=1 injection or examination visit in the past 12 months. Reported barriers were mainly related to treatment (eg, pain and discomfort during/after anti-VEGF injection), clinic (eg, not having someone to accompany them to appointments) and, to a lesser extent, the COVID-19 pandemic. After treatment, the majority recovered in <=1 day;however, 24% (139/574) needed >1 day to recover. Impairment in daily activities due to treatment was reported by 45% (258/574) of patients. Among working patients 62% (41/66) reported productivity impairment from absenteeism. Conclusion(s): Patients reported impairment of daily activities, burden and barriers related to intravitreal anti-VEGF therapy, despite high adherence and treatment satisfaction levels. More durable therapy options, requiring less frequent treatments may be able to reduce treatment-related burden and barriers. Copyright © 2022
ABSTRACT
Purpose : Anti-vascular endothelial growth factor (anti-VEGF) intravitreal injections are efficacious treatments for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME), but optimal real-world outcomes require frequent treatment and monitoring that can be burdensome to patients and hinder their ability or willingness to follow their management plan. This study aimed to understand patient treatment experience with anti-VEGF standard of care. Methods : This observational study employed a cross-sectional quantitative survey comprising de novo questions, patient-reported outcome (PRO) measures and medical chart extraction. Adult patients in the USA, UK and Canada with nAMD or DME, and treated with anti-VEGF injections for ≥12 months, were recruited via 21 (9 USA, 6 UK, 6 Canada) clinical sites. Results : Between January and August 2021, 148 (67 USA, 33 UK, 48 Canada) DME and 219 (98 USA, 54 UK, 67 Canada) nAMD patients completed their surveys. While 159 (43%) patients had a study eye visual acuity at most recent reading >70 approxETDRS letters, PRO scores indicated that patients across the two conditions had relatively high visionrelated functioning (NEI-VFQ-25) and were generally satisfied with their current treatment (MacTSQ and RetTSQ). Eighteen DME patients (12%;12% in the US, 27% in the UK, 2% in Canadian samples) and 9 nAMD patients (4%;3% USA, 3% UK, 4% Canada) missed at least 1 injection visit in the past 12 months. Reported barriers were mainly related to treatment, clinic and appointment factors, and the COVID-19 pandemic. Half of the patients reported some level of impairment in their daily activities due to the treatment. Following treatment, the majority recovered within 1 day;however, a sizable portion (24%;21% USA, 31% UK, 22% Canada) needed >1 day to recover. Among the working patients (N = 55), 34 (62%;58% USA, 67% UK, 65% Canada) reported some level of productivity impairment in the form of absenteeism. Conclusions : Despite high adherence and treatment satisfaction levels, patients reported impairment of daily activities, burden, and barriers related to treatment. In general, more DME patients missed at least 1 visit than nAMD patients. More durable treatments with longer intervals could further reduce treatment burden and address the current barriers faced by patients.
