What can we Learn from Patients' Ethical Thinking about the right 'not to know' in Genomics? Lessons from Cancer Genetic Testing for Genetic Counselling

Informed consent, genomic research and mental health: A integrative review

BACKGROUND

Research on genomics has increased while the biobank activities are becoming more common in different countries. In the mental health field, the questions concerning the potential participants' vulnerability as well as capacity to give the informed consent can cause reluctancy in recruiting persons with mental health problems, although the knowledge and understanding of mental health problems has remarkable changed, and practice is guided with inclusive approaches, such as recovery approach.

AIM

The aim of this study was to describe the current knowledge of informed consent practices in the context of genomic research on mental health from the nurses' viewpoint.

METHODS

An integrative review was conducted with search from seven international databases. Data consist 14 publications which were analyzed with thematic analysis.

ETHICAL CONSIDERATIONS

Ethical requirements were respected in every phase of the research process.

FINDINGS

Most of the papers were published in USA and between 2000-2010. Eight reports were categorized as discussion papers, four qualitative studies and one quantitative study. The thematic analysis provided information on five themes: complexity with the capacity to consent, mixed emotions towards participation, factors influencing the decision to participate, nurses' informed consent process competence and variations between consent procedures.

DISCUSSION

In the informed consent practices, there are various aspects which may affect both the willingness to participate in the study and the informed consent process itself. Implications for practice, education, research, and policies are discussed.

CONCLUSION

There is a need for more updated international research on the topic in the context of different international and national guidelines, legislation, and directives. This study provided a viewpoint to the more collaborative research activities with people with lived experiences also in this field of research following the ideas of recovery approach.

Neglected impacts of patient decision-making associated with genetic testing

We highlight non-health-related impacts associated with genetic testing (GT) and knowing one’s genetic status so that health technology assessment (HTA) analysts and HTA audiences may more appropriately consider the pros and cons of GT. Whereas health-related impacts of GT (e.g., increased healthy behaviors and avoidance of harms of unnecessary treatment) are frequently assessed in HTA, some non-health-related impacts are less often considered and are more difficult to measure. This presents a challenge for accurately assessing whether a genetic test should be funded. In health systems where HTA understandably places emphasis on measurable clinical outcomes, there is a risk of creating a GT culture that is pro-testing without sufficient recognition of the burdens of GT. There is also a risk of not funding a genetic test that provides little clinical benefit but nonetheless may be seen by some as autonomy enhancing. The recent development of expanded HTA frameworks that include ethics analyses helps to address this gap in the evidence and bring awareness to non-health-related impacts of GT. The HTA analyst should be aware of these impacts, choose appropriate frameworks for assessing genetic tests, and use methods for evaluating impacts. A new reporting tool presented here may assist in such evaluations.

Development of a Secure Website to Facilitate Information Sharing in Families at High Risk of Bowel Cancer-The Familyweb Study

Simple Summary

Families with an inherited high risk of bowel cancer may struggle to share information about their diagnosis. This means that relatives are not always aware of their increased risk of cancer or able to access screening for the early detection of cancer. Through this study, we aimed to help such families by creating a website where patients could share confidential information with their relatives securely online. Following a survey and telephone interviews with affected individuals, the content of the website was developed to suit the needs of families. Website function was tested with patients to check feasibility and acceptability. Most participants wanted more information to support their adaptation to the diagnosis and help inform their relatives. This study demonstrates how health professionals can improve access to genetic testing and cancer screening in families at high risk of cancer, thus reducing morbidity and mortality.

Abstract

Individuals with pathogenic variants in genes predisposing to bowel cancer are encouraged to share this information within their families. Close relatives at 50% risk can have access to bowel cancer surveillance. However, many relatives remain unaware of their vulnerability or have insufficient information. We investigated the feasibility and acceptability of using a secure website to support information sharing within families at high risk of bowel cancer. Patients (n = 286) answered an anonymous cross-sectional survey, with 14 participating in telephone interviews. They reported that the diagnosis had a profound effect on them and their family relationships, and consequently desired more support from health professionals. Website content was created in response to the preferences of survey and interview participants. Reactions to the website from 12 volunteers were captured through remote usability testing to guide further refinement of the website. Participants welcomed the opportunity to store and share personal information via the website and wanted more information and help informing their relatives about the diagnosis. Important website topics were: healthy lifestyle; genetic testing; and how to talk to children about the diagnosis. A website providing online access to confidential documents was both feasible and acceptable and could translate into increased uptake of cancer surveillance, resulting in lower morbidity and mortality in these families.

Clinical and epidemiological observations on individual radiation sensitivity and susceptibility

Purpose: To summarize existing knowledge and to understand individual response to radiation exposure, the MELODI Association together with CONCERT European Joint Programme has organized a workshop in March 2018 on radiation sensitivity and susceptibility.Methods: The workshop reviewed the current evidence on this matter, to inform the MELODI Strategic Research Agenda (SRA), to determine social and scientific needs and to come up with recommendations for suitable and feasible future research initiatives to be taken for the benefit of an improved medical diagnosis and treatment as well as for radiation protection.Results: The present paper gives an overview of the current evidence in this field, including potential effect modifiers such as age, gender, genetic profile, and health status of the exposed population, based on clinical and epidemiological observations.Conclusion: The authors conclude with the following recommendations for the way forward in radiation research: (a) there is need for large (prospective) cohort studies; (b) build upon existing radiation research cohorts; (c) use data from well-defined cohorts with good exposure assessment and biological material already collected; (d) focus on study quality with standardized data collection and reporting; (e) improve statistical analysis; (f) cooperation between radiobiology and epidemiology; and (g) take consequences of radiosensitivity and radiosusceptibility into account.

Delivering genomic medicine in the United Kingdom National Health Service: a systematic review and narrative synthesis

PURPOSE

We sought to assess the readiness of the United Kingdom (UK) National Health Service to implement a Genomic Medicine Service. We conducted a systematic literature review to identify what is known about factors related to the implementation of genomic medicine in routine health care and to draw out the implications for the UK and other settings.

METHODS

Relevant studies were identified in Web of Science and PubMed from their date of inception to April 2018. The review included primary research studies using quantitative, qualitative, or mixed methods, and systematic reviews. A narrative synthesis was conducted.

RESULTS

Fifty-five studies met our inclusion criteria. The majority of studies reviewed were conducted in the United States. We identified four domains: (1) systems, (2) training and workforce needs, (3) professional attitudes and values, and (4) the role of patients and the public.

CONCLUSION

Mainstreaming genomic medicine into routine clinical practice requires actions at each level of the health-care system. Our synthesis emphasized the organizational, social, and cultural implications of reforming practice, highlighting that demonstration of clinical utility and cost-effectiveness, attending to the compatibility of genomic medicine with clinical principles, and involving and engaging patients are key to successful implementation.

Choosing not to know: accounts of non-engagement with pre-symptomatic testing for Machado-Joseph disease

This paper reports accounts from people at-risk for, or affected by, Machado-Joseph disease, and their family members, about their decisions not to seek pre-symptomatic testing, therefore remaining (for the time) uninformed about their genetic status. We draw on individual and family semi-structured interviews with participants recruited through a national patient's association (n = 25). Qualitative thematic analysis revealed three main categories of accounts: (1) justifying the decision "not to know", because either no clinical benefit was expected or predictive knowledge was anticipated as psychologically burdensome; (2) prioritizing everyday life, maintaining hope and the goal of living a valid life; and (3) the wish to know: ambivalence and conflict within the family. Findings suggest the value of genetic information is often questioned when no effective treatment or cure is available; and that people have different tolerance thresholds for predictive information, and this impacts individuals within the family differently. We discuss this in the context of the making of "responsible" decisions, and of the tensions that may arise within families between the best interests or wishes of a person and those of other family members. We hope this will clarify the reasoning of those who opt for non-engagement with medical genetic services and, more specifically, pre-symptomatic testing. Further, we hope it will be relevant for the provision of genetic counselling and psychosocial support to such families.

Balancing the Economics and Ethics of Personalised Oncology

The cost of personalised medicine in oncology is increasing. The varied and contrasting priorities of the pharmaceutical industry, local and national governments, international medical community, and patients need to be reviewed and balanced. In addition to the economic and political standpoints on this issue, the ethical considerations from physicians' viewpoints need to be considered to optimise cancer patients' care. In this paper we discuss the way research and development (R&D) of these drugs is carried out and reimbursed, and how this needs to change. We describe frameworks assessing the value of these treatments which been developed. Physicians need to develop their knowledge and understanding of these issues to best meet their dual responsibilities of advocating for their patients and promoting public health.

Society and personal genome data

Genomic data offer a goldmine of information for understanding the contribution of genetic variation makes to health and disease. The potential of genomic medicine, to predict, diagnose, manage and treat genetic disease, is underpinned by accurate variant interpretation. This in itself hinges on the ability to access large and varied genomic databases. There is now recognition that international collaboration between research and healthcare systems are paramount to delivering the scale of genomic data required. No single research group, institute or country will liberate our understanding, it is only through global cooperation, together with super computing power, will we truly make sense of how genotype and phenotype correlate. Whilst it is logistically possible to create computing systems that talk to each other and aggregate datasets ready to reveal novel correlations, the bottom line is that this will only happen if people (whether they be scientists, clinicians, patients, research participants, policy makers, politicians, law makers) support the principle that we should be donating, accessing and sharing our DNA data in this way. And in order to make the most sense of genomics, given the geographical and ancestral variation between us, such people are likely to be the majority of society. Within this review, a perspective is proffered on the human story that underpins genomic 'big data' access and how we are at a tipping point as a society-we need to decide collectively, are we in? and if so, what needs to be in place to protect us? or are we out?

Genetics in the 21st Century: Implications for patients, consumers and citizens

The first human genome project, completed in 2003, uncovered the genetic building blocks of humankind. Painstakingly cataloguing the basic constituents of our DNA ('genome sequencing') took ten years, over three billion dollars and was a multinational collaboration. Since then, our ability to sequence genomes has been finessed so much that by 2018 it is possible to explore the 20,000 or so human genes for under £1000, in a matter of days. Such testing offers clues to our past, present and future health, as well as information about how we respond to medications so that truly 'personalised medicine' is now moving closer to a reality. The impact of such a 'genomic era' is likely to have some level of impact on an increasingly large number of us, even if we are not directly using healthcare services ourselves. We explore how advancements in genetics are likely to be experienced by people, as patients, consumers and citizens; and urge policy makers to take stock of the pervasive nature of the technology as well as the human response to it.

Addressing Hereditary Cancer Risk at the End of Life

Oncology guidelines clearly outline evidence-based recommendations for patients with newly diagnosed cancer to help oncologists determine which patients are appropriate for a genetic assessment. Ideally, patients with newly diagnosed cancer, who have personal or family histories suggestive of hereditary cancer predisposition, are referred for genetics work up in the nonurgent setting. However, in some cases, a genetics work up is delayed until the end of life. This is a time of heightened stress and additional obstacles, including discordance between family members regarding the obtainment of genetic information, paying for testing, selecting a surrogate to receive and disperse information in the case of a patient's death, and the use of DNA banking for future evaluation. To meaningfully participate and support patients, family members, and our colleagues facing requests at the end of life for genetic testing, we provide a practical approach and highlight resources to effectively engage in this rising challenge.
