A qualitative study among patients with an inherited retinal disease on the meaning of genomic unsolicited findings

Patient experiences and perceived value of genetic testing in inherited retinal diseases: a cross-sectional survey

This study evaluated patient experiences with genetic testing for inherited retinal diseases (IRDs) and the association between underlying knowledge, testing outcomes, and the perceived value of the results. An online survey was distributed to adults with IRDs and parents/guardians of dependents with IRDs who had had genetic testing. Data included details of genetic testing, pre- and post- test perceptions, Decision Regret Scale, perceived value of results, and knowledge of gene therapy. Of 135 responses (85% from adults with IRDs), genetic testing was primarily conducted at no charge through public hospitals (49%) or in a research setting (30%). Key motivations for genetic testing were to confirm IRD diagnosis and to contribute towards research. Those who had received a genetic diagnosis (odds ratio: 6.71; p < 0.001) and those self-reported to have good knowledge of gene therapy (odds ratio: 2.69; p = 0.018) were more likely to have gained confidence in managing their clinical care. For over 80% of respondents, knowing the causative gene empowered them to learn more about their IRD and explore opportunities regarding clinical trials. Key genetic counselling information needs include resources for family communications, structured information provision, and ongoing genetic support, particularly in the context of emerging ocular therapies, to enhance consistency in information uptake.

Impact of inherited retinal diseases on Canadian patients and families: a mixed-methods study

OBJECTIVE

To understand the physical, psychosocial, and practical challenges faced by Canadian patients with inherited retinal diseases (IRDs) and their families.

DESIGN

Mixed methods.

PARTICIPANTS

A total of 408 Canadians living with or caring for someone with an IRD (mean age = 51.4 ± 16.7 years) completed an online survey. Twenty cohort respondents participated in additional telephone interviews.

METHODS

The online survey was comprised of questions concerning demographics, self-reported vision, genetic testing, information preferences, health care experiences, treatment goals, and disease impact on daily life. Recruitment occurred through Fighting Blindness Canada's community database. Survey dissemination also occurred via social media and not-for-profit stakeholder outreach. Subsequent to survey completion, a subset of respondents participated in semistructured telephone interviews to further elucidate illness experience.

RESULTS

Respondents identified having 1 of more than 14 IRDs, with 72% specifying retinitis pigmentosa. Sixty-eight percent reported being legally blind, and more than 85% self-reported moderate to low vision or worse. IRDs impacted daily functioning, with 53% of respondents indicating that they affected employment or education. Psychological challenges were evident, with more than 70% worried about coping with daily life and more than 60% indicating fear and stress. Qualitative data described hopelessness around suitable work, loss of independence, and challenges with social interaction. Sixty-five percent reported a negative impact on family life. Many had not accessed social support services because of a lack of perceived need, awareness, or availability.

CONCLUSION

Canadian patients with IRDs report moderate to severe visual impairment, and both patients and their families describe an impact on psychosocial well-being and functioning during daily activities. Vision rehabilitation with a psychosocial approach is necessary, alongside facilitating access to emerging treatments.

Persuasive Appeals in Genetic Biobank Recruitment Campaigns: Social and Ethical Implications

The social and ethical implications of large-scale biobank donor recruitment campaigns have remained understudied. We use two recent campaigns of the population-based genetic biobank in Estonia as an example to demonstrate how campaign spokespersons try to persuade potential donors by appealing to (1) gaining self-knowledge, (2) gaining control over one's health, (3) fear of illness, (4) contributing to healthcare, (5) contributing to science, and (6) contributing to one's country. While these campaigns succeeded in recruiting 15 percent of the country's adult population as donors, we explain how the use of some of these appeals may (a) create unrealistic expectations regarding the benefits donors could receive and (b) conceal the risks regarding health data. The study lays a necessary groundwork for future empirical research on the ethics of biobank recruitment campaigns.

Disparities in Inherited Retinal Degenerations

To review disparities in the field of inherited retinal degenerations to establish foundations for future discussions oriented toward finding possible solutions. A narrative overview of the literature. Despite collective efforts towards democratization of genetic testing and investigation, genetic databases containing primarily European populations are heavily relied upon. Access to specialized care and other resources is also still not available to all. Recognizing and addressing disparities and inequities within the field of inherited retinal degenerations will improve our care of these patients and our knowledge of their conditions.

Experiences of genetic testing among individuals with retinitis pigmentosa

BACKGROUND

Retinitis pigmentosa (RP) is a genetically heterogeneous retinal dystrophy which results in progressive vision loss. There is scant literature on the experiences of genetic testing in patients with RP.

MATERIALS AND METHODS

Patients with a clinical diagnosis of RP who received genetic testing at the Wills Eye Ocular Genetics clinic between 2016 and 2020 were recruited. Telephone interviews were conducted using a semi-structured guide designed to elicit participant experiences with genetic testing. A thematic analysis was performed to describe patterns in participant responses.

RESULTS

Twelve patients participated. Seven participants identified as female and five as male, with ages ranging from 22 to 70. Ten patients had positive genetic test results, while two had negative genetic testing. Reported motivations for genetic testing included qualification for clinical trials (58% of total participants), determination of etiology or usal gene (50%), reproductive concerns (50%), and prognostic outlook (50%). Most participants (75%) expressed satisfaction about their decision to pursue genetic testing. Participants with both positive and negative genetic testing reported persistent uncertainty regarding their prognosis for visual decline (50%). Genetic confirmation of disease leads to initiation of safety and vision-protecting health behaviors (42%).

CONCLUSION

Patients with RP are generally satisfied with their testing experience, despite approaching testing with a wide range of motivations and expectations. Future research can leverage this methodology to identify targets for improvement in pre- and post-test education and counselling.
