Impact of COVID-19 on Quality of Life of Seniors With Eye Disease and Implementations to Improve Wellness

The ophthalmology clientele is vulnerable in the context of the coronavirus disease 2019 (COVID-19) pandemic because of their age and comorbidities. Specifically, elderly patients aged 65 and above with glaucoma, age-related macular degeneration, or diabetic retinopathy require regular follow-ups and commonly suffer from additional comorbidities. Further, because of the proximity between the patient and health care personnel during ophthalmological examinations, the risk of infection during visits is significant. The delicate balance between the risk of exposure to COVID-19 and visual loss in delaying cases is a psychological stressor to both patients and clinicians.

A cross-sectional study accumulating the data of 425 patients aged 65 and above with various eye diseases will be conducted. Participants will be presented with a set of online questionnaires designed to collect data on health-related quality of life (HRQOL), vision-related quality of life (VRQOL), depression symptoms, anxiety, sleep quality, community integration, and their experience with tele-consultations. This study can help quantify the collateral impact of the COVID-19 beyond the direct impact of the virus, to improve future quality of care guidelines on non-COVID-19 conditions, and to help plan patient prioritization once restrictions are eased.

BACKGROUND AND RATIONALE

COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Like many healthcare departments, the department ophthalmology presents risk of COVID-19 infection. As a result, the present pandemic has led officials to rethink the management of patient lists and to restrict the patients to be assessed or to be operated based on the urgency of their condition in accordance with ministerial guidelines. A delay in visits might increase the risk of visual loss not only through the delay of necessary care, but also through an increase in non-adherence to treatment. Indeed, patients themselves might decide to interrupt their treatment or postpone their visit for fear of contracting the disease. There is concern not only about compliance to treatment, but also about accessibility issues to medications in high-demand and modifications of treatment protocols.

Elderly people aged 65 and above are commonly afflicted by many eye diseases with vision loss. Furthermore, during times of the COVID-19 pandemic, this population can be vulnerable to possible vision loss due to a delay of care.

As a result, it is being proposed to perform a cross-sectional study using a sample of patients from this population to gather information on follow-up and treatment delays associated with the pandemic's offloading measures as well as any adverse effects on visual acuity that have occurred during the pandemic. The evidence collected from this study could be translated into clinical practices helping to provide recommendations to adjust the response to the COVID-19 pandemic in ophthalmological management.

Visual loss, potentially due to the reasons that were mentioned above, can bring about depressive symptoms and deteriorate the quality of life (QOL). In the proposed study, the investigators have included questionnaires to assess the various stressors brought on during the COVID-19 pandemic such as fear of vision loss, health-related QOL, vision-related QOL, depression and anxiety symptoms, sleep quality, number of ER visits for deterioration of mental health. This evidence base collected from this study could, once again, be translated into clinical practices helping to provide recommendations to adjust the response to the COVID-19 pandemic in ophthalmological management.

STUDY AIM

Through a cross-sectional survey, the investigators aim to build an evidence base to provide decision-makers with high quality, timely, and relevant evidence and to translate this knowledge into clinical practices by providing real-time knowledge and recommendations to adjust the response to the COVID-19 pandemic in ophthalmological management.

STUDY OBJECTIVES AND HYPOTHESES

Primary objectives: To build an evidence base to provide decision-makers with high quality, timely, and relevant evidence and to translate this knowledge into clinical practices by providing real-time knowledge and recommendations to adjust the response to the COVID-19 pandemic in ophthalmological management.

Secondary objectives: Using a cross-sectional survey, the investigators will: 1) document the follow-up and treatment delays associated with the pandemic's offloading measures 2) determine whether any adverse effects on visual acuity occurred during the pandemic 3) determine the impact on mental health (e.g. fear of vision loss, health-related QOL, vision-related QOL, depression and anxiety symptoms, sleep quality, number of ER visits for deterioration of mental health) 4) determine the role and impact of virtual care (telemedicine, teleconsultation) in the state of the current pandemic and provide additional data for the long-term implementation of telemedicine in vision care.

METHODOLOGY

Study Design

A cross-sectional survey will be performed to gather the data required to build an evidence base to provide decision-makers with high-quality, timely, and relevant evidence, as well as to translate this knowledge into clinical practices.

Study Population and Setting

Patients from the Ivey Eye Institute, St. Joseph's Health Care London, ON will be recruited in-person, similar to the previous and ongoing research studies by the investigators, based on inclusion and exclusion criteria.

Recruitment

It is being hoped to complete recruitment within a year of receiving ethics approval. Based on previous experience, it is planned to recruit at an average rate of 4 participants/week in a staggered manner over a 9 to 10-month period.

Data Fidelity, and Management

Day-to-day Management of the Study

The RAs will oversee the coordination and monitoring of the overall study. They will prepare all documents required for informed consent and questionnaire administration. They will also be responsible for recruitment, data management (Qualtrics), data analysis, and preparation of presentations and manuscripts. They will be trained on the TTO, VFQ-25, CES-D, HADS-A, PSQI, and CIQ by the Primary Investigator (PI). They will receive ongoing supervision throughout the study by the PI and the co-investigator with the aim of approaching a reliability level of Intra Class Correlation (ICC) \> .80 on all scales. Weekly meetings will be organized by the investigators to ensure recruitment and progression of the study.

Fidelity of Assessments

The RAs will be trained and supervised weekly by the PI.

Recruitment, Screening, and Consent Process

425 eye disease patients will be recruited for this study as described previously in the recruitment procedures section. Physicians at Ivey Eye Institute will identify potential participants based on the inclusion and exclusion criteria, as described previously. The potential participants will be asked whether they wish to participate in the following study. Physicians will then refer the patients expressing interest who meet recruitment criteria to the research assistant (RA) for an in-person interview to obtain informed consent or obtain contact information to obtain informed consent electronically.

Potential participants will be presented with an electronic letter of information and consent (LOI). The RA will briefly describe the study to these potential participants and offer to send an electronic copy of the LOI by e-mail. The LOI will contain the contact information of the study investigators and RAs on the front cover page and the study description. In addition, those patients expressing interest will be asked if they consent to providing their contact information (name, phone number, and/or e-mail address). Upon receiving consent to participate in the study, the RA will collect the participant's email and telephone number and present the online survey to be completed.

If the participant presents significant distress (severe depression as confirmed by a CES-D ≥ 24), the PI will be required to respond within 48 hours upon receiving the questionnaire result. The participant in distress will be referred to a mental health provider for further screening for presence of imminent suicidality and safety. The mental health provider will determine whether they have suicidal intent (the wish to harm or kill themselves). In the rare event that there is what is considered an imminent risk, such participants will be referred to the Centralized Emergency Psychiatry Service (CEPS) at the Victoria Hospital.

OUTCOMES

Qualitative Measures Outcomes

Mental health, physical health, patient experience with virtual care, fear of vision loss, and change in vision during the pandemic as measured using 5-point Likert scale multiple-choice format questionnaires.

STATISTICAL ANALYSIS AND SAMPLE SIZE

Data analysis

The investigators will examine the descriptive statistics for the participants group and check for outliers. It is planned to use a linear-mixed model with the score as the dependent variable, demographic variables as covariates. Univariate and bivariate analysis will be performed for each independent variable against the dependent variable to elicit the impact of each co-variate on the pattern of preference based HRQoL, depression, anxiety, community integration, and sleep quality without adjusting for the effect of other variables. Models will be deemed statistically significant if they are associated with a significant F value (p \< 0.01) and if they explain over 15% variability of the dependent variable. Only those independent variables that are statistically significantly associated with the preference based HRQoL (p \< 0.05) will be used for model construction.

STATA 15.0 will be used to run all statistical analysis. Based on population size of adults with eye diseases above the age of 65 in South Western Ontario, 5% margin of error, and 95% confidence interval, the sample size has been computed to be 384 participants. Given a 10% attrition rate, the study sample size of 425 participants will be adequate. As such, the sample size has been set to n = 425.

POTENTIAL RISKS/ADVERSE EFFECTS

Risks and Safety of Participants

There are also no direct risks associated with administering the questionnaires to the participants in this study. It does not involve any procedures or medical tests. It is not anticipated that there will be any increased risk in completing any of the questionnaires. It could be that certain questionnaire items make one remember life events which could be potentially disconcerting. Any indications of serious mental health issues will be reported immediately for further clinical assessment and management. Standard of care will be unaffected and only capable and consenting participants will be recruited into the study. COVID-19 restrictions will be respected including the proper donning of personal protective equipment, and sanitation of surfaces and hands. Potential risks to data collection include a privacy breach since there will be various questionnaires to collect information from patients.

Privacy, Confidentiality, and Data Protection

Electronic research records will be stored using QUALTRICS up to a period of 15 years. Study team members may access data on QUALTRICS, download this data and store the data. Any such activities will be done under the direction and supervision of the PI. Data will be coded to protect participant confidentiality.
