Impact of COVID-19-associated anxiety on the adherence to intravitreal injection in patients with macular diseases a year after the initial outbreak

Abstract

Background: As the primary burden of treating COVID-19 patients began to ease in the United Kingdom, ophthalmology clinic volume within the National Health Service has since recovered. Alarmingly, the rate of non-attendance remains higher than the pre-pandemic level. Purpose: The purpose was to assess how the perceived risk of contracting coronavirus disease 2019 (COVID-19) influences the willingness of individuals with sight-threatening macular conditions to attend intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection appointments during the second wave of the pandemic. Methods: This prospective cross-sectional survey was conducted at the Macular Treatment Centre, Manchester Royal Eye Hospital. Patients who missed their appointment in January 2021 were invited to complete an anonymous survey over the telephone. The survey consisted of two parts: (1) a 23-item questionnaire aiming to assess fear of contracting COVID-19 in different hospital-related settings; and (2) the validated COVID-19 Anxiety Syndrome Scale (C-19ASS) to evaluate COVID-19-related anxiety. Results: A total of 104 patients agreed to participate in the survey. Only a small proportion of patients believed COVID-19 vaccination (23 out of 88, 26.1%) had influenced their willingness to attend injection appointments. Majority of patients felt concerned about contracting COVID-19 during hospital appointments ( n = 63, 60.6%). Only a minority of patients ( n = 36, 34.6%) agreed with the hospital guidance on minimising clinical examinations during clinic visit. The C-19ASS was significantly higher in female patients, those older than 70 years and those with mobility issues. Higher C-19ASS, older age and living alone were predictors of clinic nonattendance. Conclusion: COVID-19 anxiety and fear of viral exposure could adversely affect patient adherence to clinic appointments during the pandemic. Particular attention should be provided to older patients, those who live alone and patients with impaired mobility. This is particularly relevant as hospital eye services across the world are in the process of restarting.
