Impact of Meditation on Improving Quality of Life Among Glaucoma Patients: An Electronic Pilot Feasibility Study

Study Overview
=================
Brief Summary
-----------------
Glaucoma is a chronic disease that causes loss of vision and potentially blindness as a result of optic nerve damage due to increased intraocular pressure. Currently, it is the leading cause of irreversible blindness worldwide1. In 2020, 4.1 million and 3.6 million adults over the age of 50 suffered from mild to severe visual impairment and blindness respectively induced by glaucoma1. However, these predictions are likely underestimated since glaucoma can remain asymptomatic until later stages in disease progression2. There is a convincing body of evidence suggesting that there is a linear relationship between visual impairment and decreased quality of life (QOL) among glaucoma patients3. Furthermore, evidence from The National Health and Aging Trends Study suggests that this relationship may be bidirectional where older adults with visual impairment are more likely to suffer from mental illness and older adults with mental illness are more likely to suffer from visual impairment4. Mindfulness-based meditation is a promising non-pharmacological treatment that has been shown to reduce intraocular pressure and improve QOL in patients with glaucoma5. A feasibility study will be conducted using a mixed-method design to assess the feasibility of delivering a meditation intervention online to enhance the QOL and mental health of glaucoma patients. Participants will be recruited and randomized in blocks of 10 and will undergo 1:1 randomization to the intervention arm or usual care arm. The purpose of this block randomization technique is to minimize the wait time between patient recruitment and study initiation. Participants in each arm will complete online questionnaires at patient recruitment, weeks 1, 3, 6, and 12 to measure self-reported health, depression symptoms, anxiety, and sleep quality using REDCap, an electronic data capturing system provided by Lawson Health Research Institute (LHRI).

Design Details

Primary Purpose: Supportive Care
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Meditation to Remove Stress and Create A Proper System in Mind<br>The study intervention will be administered to participants randomized to the intervention arm. The meditation intervention will be delivered virtually via the hospital-approved Microsoft Teams platform. Participants will be taught an evidence-based meditation technique which includes two online sessions (60 minutes/day) with a trained, experienced, and certified teacher of Prasanna Wellness, a non-profit service organization. Participants will learn how to respond to experiences that arise in meditation, will discuss what enhances or detracts from effective meditation, and review methods for meditating at home. The participants in the intervention arm will complete 60-minute follow-up sessions with the Prasanna Wellness staff which will include 33 minutes of guided meditation practice, and then a discussion of participants' experiences with meditation during the week, additional observations, and a review of relevant knowledge to support their home practice. | Behavioral: Meditation to Remove Stress and Create A Proper System in Mind<br>* Meditation to Remove Stress and Create A Proper System in Mind is a guided meditation.<br>* Other names: Beyond Mindfulness Meditation;|
| No Intervention: Usual Care<br>Participants will continue with their usual care. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The 12-item short form survey | The 12-Item Short Form Survey (SF-12) is a questionnaire that measures self-reported health. Scores are calculated by converting the sum of responses to a scale from 0 to 100 where a higher score indicates superior health. In addition, results can be summarised using the physical component summary (PCS) score and the mental component summary (MCS) score. | Week 1, week 3, week 6, week 12 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Depression | Depression is a feeling of severe despondency and dejection. Depression will be measured using the Center for Epidemiological Studies - Depression (CES-D) score. The CES-D provides scores from 0 to 60. Higher scores indicate worse outcome. | Week 1, week 3, week 6, week 12 | 
| Anxiety | Anxiety will be measured using Hospital Anxiety and Depression Scale - Anxiety (HADS-A) subscale. The HADS-A provides scores from 0-21. Higher scores indicate worse outcome. | Week 1, week 3, week 6, week 12 | 
| Sleep quality | Sleep quality as measured using the Pittsburgh Sleep Quality Index (PSQI) scores. The PSQI provides scores from 0-21. Higher scores indicate worse outcome. | Week 1, week 3, week 6, week 12 |
