Genetic Testing Experiences of People Living with Inherited Retinal Degenerations: Results of a Global Survey.

INTRODUCTION: Obtaining a genetic diagnosis via genetic testing (GT) is a fundamental step in determining the eligibility of a patient to be enrolled in emerging clinical trials and research studies. Besides, the knowledge of genetic outcome allows patients to plan for significant life choices. However, critical barriers exist to an equitable access to genetic services globally. The objective of this study was to explore patient experiences while seeking genomic services for inherited retinal degenerations (IRDs). METHODS: An online survey was designed based on a focus group conducted by Retina International and including people affected by IRDs and their families living in different regions around the world. The survey was then circulated to 43 Retina International member organisations globally via email newsletters and social networks. The survey involved questions in relation to the accessibility, affordability, and timeliness of genomic services for IRDs as well as patient perceived awareness of genomic services for IRDs among healthcare professionals. RESULTS: A total of 410 respondents (IRD patients and caregivers) from over 30 countries across all continents responded to the survey. A considerable number of the patients had to go through a long and arduous journey to access GT and counselling services, wherein 40% had to visit more than 5 physicians, 27% had to visit more than 5 clinics, and 57% had to wait for more than 3 years before obtaining a genetic diagnosis. Furthermore, 46% of respondents reported not receiving genetic counselling prior to undergoing GT, and 39% reported not receiving genetic counselling after undergoing GT. Over 3/4th of the participants reported that they did not have to pay for their genomic services for IRDs. Thirty-seven percent of the respondents reported that their eye care professionals (ECPs) were either not aware of GT, remained neutral, or did not encourage them to undergo GT. CONCLUSION: Patients with IRDs do not have equitable access to best practice GT and counselling services. Greater awareness and training regarding IRDs and the benefits of GT and genetic counselling for patients and families are needed among ECPs. A best practice model on access to genomic services for IRDs is required.

Save our Sight (SOS): a collective call-to-action for enhanced retinal care across health systems in high income countries.

With a growing aging population, the prevalence of age-related eye disease and associated eye care is expected to increase. The anticipated growth in demand, coupled with recent medical advances that have transformed eye care for people living with retinal diseases, particularly neovascular age-related macular degeneration (nAMD) and diabetic eye disease, has presented an opportunity for health systems to proactively manage the expected burden of these diseases. To do so, we must take collective action to address existing and anticipated capacity limitations by designing and implementing sustainable strategies that enable health systems to provide an optimal standard of care. Sufficient capacity will enable us to streamline and personalize the patient experience, reduce treatment burden, enable more equitable access to care and ensure optimal health outcomes. Through a multi-modal approach that gathered unbiased perspectives from clinical experts and patient advocates from eight high-income countries, substantiated perspectives with evidence from the published literature and validated findings with the broader eye care community, we have exposed capacity challenges that are motivating the community to take action and advocate for change. Herein, we propose a collective call-to-action for the future management of retinal diseases and potential strategies to achieve better health outcomes for individuals at-risk of, or living with, retinal disease.

The Impact of Inherited Retinal Diseases in the United States of America (US) and Canada from a Cost-of-Illness Perspective.

OBJECTIVE: To estimate the annual cost of inherited retinal diseases (IRDs) in the United States of America (US) and Canada from a societal perspective - including costs to the health system, individual and family productivity costs, lost wellbeing and other societal economic costs - by setting and payer. Findings will inform the need for policy action to mitigate the impact of IRDs. METHODS: The costs of IRDs were estimated using a cost-of-illness methodology, based on the prevalence of IRDs in each country. Intangible costs of reduced wellbeing were also estimated using disability-adjusted life years which were then converted to monetary values using the value of a statistical life. RESULTS: Using base prevalence rates, total costs attributable to IRDs in the US were estimated to range between US$13,414.0 and US$31,797.4 million in 2019, comprising both economic costs (between US$4,982 and US$11,753.9 million; 37% of total costs) and wellbeing costs (between US$8,431.7 and US$20,043.6 million; 63%). Total costs attributable to IRDs in Canada were estimated to range between CAN$1637.8 and CAN$6687.5 million in 2019, comprising both economic costs (between CAN$566.6 and CAN$2,305.7 million; 34%) and wellbeing costs (between CAN$1,071.4 and CAN$4,381.9 million; 66% of total costs). CONCLUSION: The impact of IRDs in the US and Canada is substantial when considering both economic costs and reduced wellbeing. The wellbeing costs due to IRDs in the US and Canada are considerable, accounting for over 60% of total costs. Vision loss from IRDs often manifests in childhood, meaning some people live with vision impairment and blindness for their whole lives. Further research into current and emerging cost-effective therapies and interventions is required given the substantial economic burden faced by those living with vision loss.

The Impact of Inherited Retinal Diseases in the Republic of Ireland (ROI) and the United Kingdom (UK) from a Cost-of-Illness Perspective.

To date, there has been a global lack of data regarding the prevalence of conditions falling under the Inherited Retinal Diseases (IRD) classification, the impact on the individuals and families affected, and the cost burden to economies. The absence of an international patient registry, and equitable access to genetic testing, compounds this matter. The resulting incomplete knowledge of the impact of IRDs hinders the development and commissioning of clinical services, provision of treatments, and planning and implementation of clinical trials. Thus, there is a need for stronger evidence to support value for money to regulatory bodies for treatments approved, and progressing through clinical trials. To ensure a strategic approach to future research and service provision, it is necessary to learn more about the IRD landscape. This review highlights two recent cost-of-illness reports on the socio-economic impact of 10 IRDs in the Republic of Ireland (ROI) and the United Kingdom (UK), which demonstrate the comprehensive impact of IRDs on individuals affected, their families, friends and society. Total costs attributable to IRDs in the ROI were estimated to be £42.6 million in 2019, comprising economic (£28.8 million) and wellbeing costs (£13.8 million). Wellbeing costs were estimated using the World Health Organization (WHO) burden of disease methodology, a non-financial approach, where pain, suffering and premature mortality are measured in terms of disability-adjusted-life-years (DALYs). In the UK, wellbeing costs attributable to IRDs were £196.1 million, and economic costs were £327.2 million amounting to £523.3 million total costs in 2019. Accounting for over one-third of total costs, the wellbeing burden of persons affected by IRDs should be emphasized and factored into reimbursement processes for therapies and care pathways. This targeted review presents the most current and relevant data on IRD prevalence in the ROI and the UK, and the impacts (financial and non-financial) of IRDs in terms of diagnosis, wellbeing, employment, formal and informal care, health system costs, deadweight losses and issues surrounding payers and reimbursement. This review demonstrates IRD patients and their families have common issues including, the need for timely equitable access to genetic testing and counselling, equality in accessing employment, and a revision of the assessment process for reimbursement of therapies currently focused on the cost-of-illness to the healthcare system. This review reveals that IRD patients do not frequently engage the healthcare system and as such suggests a cost-of-illness model from a societal perspective may be a better format.

Rare Disease Research Partnership (RAinDRoP): a collaborative approach to identify research priorities for rare diseases in Ireland.

Background: The Rare Disease Research Partnership (RAinDRoP) was established in 2018 to bring together a wide variety of diverse voices in the rare disease community in Ireland and form a research partnership. This approach enabled clinicians, patients, carers and researchers to work together to identify top research priorities for rare diseases, which focused on a life-course perspective rather than a disease-specific need.                                                                                                           Methods: A participatory multiple phase approach was used to identify research priorities for rare diseases. The research process involved three main phases: Phase I, Public Consultation Survey on Research in Rare Diseases in Ireland (PCSRRDI); Phase II, Research Prioritisation Workshop (RPW); Phase III, Follow-up Public Consultation and Prioritisation Survey (FWPCPS). Results: In total, 240 individuals completed the phase I PCSRRDI, which comprised of a cross-section of health care professionals, researchers and people living with rare diseases. One thousand and fifteen statements were collected, reflecting issues and shared challenges in rare diseases. A shortlisting step by step was used to identify any statements that had received a total score of above 50% into 10-12 researchable questions or statements per the theme for the phase II workshop. Phase II was focused on three main themes: (1) Route to Diagnosis, (2) Living with Rare Disease, (3) Integrated and Palliative Care. In total, 62 individuals attended the overall workshop; 42 participated in the prioritisation sessions. A cross-section of health care professionals, researchers and people living with rare diseases were engaged at each workshop. Seventy-five individuals completed the final phase III public ranking by priority responses, and they ranked the top 15 research priorities defined by the multi-stakeholders at the phase II consensus meeting. Conclusions: This study identified priorities for rare diseases research aimed at improving the health and wellbeing of people living with rare diseases.
