Amblyopia-A novel virtual round table to explore the caregiver perspective

PURPOSE

A survey aimed to capture the caregiver's perspective on the impact of amblyopia and its treatment on the child and family, as well as caregivers' views on the design and feasibility of clinical trials investigating dichoptic binocular therapies for amblyopia.

METHODS

Parents of amblyopic children, patient advocates and healthcare professionals took part in a moderated, structured discussion on a novel virtual advisory-board platform.

RESULTS

Seven parents of children with amblyopia, two patient organisation representatives, one ophthalmologist and one optometrist participated in the survey. A total of 645 posts were entered on the platform over a 14-day period in September 2021. There was widespread agreement that the management of amblyopia poses more of a burden on the child and family than the condition itself, with treatment burden accentuated when treatment is unsuccessful. Parents expressed uncertainty and frustration in relation to the duration of patching, success of patching and alternative treatment options, and felt there was inadequate readily available, easy-to-understand information on the condition. Parents reported that a new treatment for amblyopia, such as dichoptic binocular therapy using video games, should be safe, non-invasive and engaging compared with an eye patch. Treating at home, potentially for a shorter treatment duration, and with an entertaining game were the main reasons parents would join a clinical study with this type of novel therapy. However, due to a limited critical period treatment window, parents would feel more comfortable joining a clinical trial if traditional therapies were offered in conjunction with those under investigation.

CONCLUSION

Patient perspectives and the role of caregivers in the acceptance of any interventional treatments are increasingly recognised. Understanding how amblyopia and its treatment impacts a child and family should be an important premise to guide therapy and evaluate treatment value, both in clinical trials and in routine medical practice.

Patient perspectives on dry eye disease and chronic ocular surface pain: Insights from a virtual community-moderated dialogue

PURPOSE

To understand patients' perspectives on living with dry eye disease (DED), and on the unmet needs in DED and chronic ocular surface pain (COSP) management.

METHODS

A moderated, structured discussion with patients with ocular surface diseases and healthcare professionals (HCPs) was conducted using a virtual platform to capture patients' journey with DED, their opinion on unmet needs, and design and conduct of clinical trials in DED and COSP.

RESULTS

Nine participants, including four patient representatives from patient organisations, one ophthalmologist and one optometrist participated in the discussion. Patients had DED of varying severity and aetiology; three patients had Sjögren's. Over 4 weeks, 785 posts were entered on the platform. Prior to diagnosis, patients rarely associated their symptoms with DED. Convenience and symptomatic relief scored higher than treating the disease. Patients expressed the need for plain language information and dialogue with knowledgeable and sensitive HCPs. Online forums and social media were suggested as key recruitment resources, whereas convenience and safety concerns were highlighted as main barriers to enrolment. The need for the inclusion of outcome measures that have a real impact on patients' experience of their condition was highlighted. Both target product profiles were received positively by participants, highlighting the twice-daily dosing regimen and convenience of the products. Participants acknowledged the value of digital tools and suggested the need to feel valued post-trial.

CONCLUSIONS

This moderated dialogue provided actionable insights on the unmet needs in DED and useful inputs for consideration when designing future clinical trials for DED and COSP.

Patient Preferences in the Management of Wet Age-Related Macular Degeneration: A Conjoint Analysis

INTRODUCTION

To identify patient preference drivers related to the management of wet age-related macular degeneration (wet AMD).

METHODS

In this cross-sectional study, a self-explicated 'conjoint analysis' survey was administered online to eligible patients with wet AMD (receiving anti-vascular endothelial growth factor [VEGF] treatment for at least 12 months) from the USA, Canada, UK, France, Spain, Germany, Italy, Japan, Taiwan, and Australia. The survey consisted of six domains with 21 attributes, which were selected on the basis of a literature review, social media listening, and tele-interviews/discussions with patients, clinical experts, and patient groups. Utility and relative importance scores were generated for each attribute and utility difference significance testing was performed using 'unequal variances t tests'. The Patient Activation Measure (PAM-13) questionnaire was administered to assess patients' knowledge, skill, and confidence in self-management.

RESULTS

A total of 466 patients (mean age, 68 years; women, 54%; binocular wet AMD, 28%) with an average anti-VEGF treatment duration of 3.9 years completed the survey. The most important preference domains were 'treatment effects on vision' (non-significant) and 'vision-related symptom burdens' (p < 0.001), followed by 'treatment risk' (p < 0.05), 'impact on daily activities' (p < 0.05), 'burden of clinic/hospital visits' (p < 0.001), and 'impact on psychological well-being'. The five most important attributes in order of importance were clarity of vision, treatment effect on symptoms, quality of vision, time to treatment effect, and time to re-administration. The two most important attributes globally were also in the top three attributes across countries. The majority of participants in the study were level 3 or level 4 of the PAM-13 questionnaire.

CONCLUSIONS

This study identified the most important disease and treatment attributes to patients using patient-centred methods. The data showed the degree of harmonization of preferences across geographies and that participants actively adopt behaviours required for improved treatment outcomes. The identified preference drivers may inform future clinical development.

MSBase: an international, online registry and platform for collaborative outcomes research in multiple sclerosis

Observational cohort studies are a powerful tool to assess the long-term outcome in chronic diseases. This study design has been utilized in local and regional outcome studies in multiple sclerosis (MS) and has yielded invaluable epidemiological information. The World Wide Web now provides an excellent opportunity for an international, collaborative cohort study of MS outcomes. A web platform--MSBase--has been designed to collect prospective data on patients with MS. It is purely observational, enabling participating neurologists to contribute data on diagnosis, treatment and progress, to review anonymous aggregate data and to benchmark their patient population against other patient subsets or the entire dataset. MSBase facilitates collaborative research by allowing the online creation of investigator-initiated regional, national and international substudies. The registry aims to answer epidemiological questions that can only be addressed by prospective assessments of large patient cohorts. The registry is funded through the independent MSBase Foundation, and governed by an International Scientific Advisory Board. The MSBase Foundation commenced operations in July 2004 and since then, 22 neurologists from 11 countries have joined MSBase and are contributing 2400 patients to the total data pool.
