Experiences with obtaining informed consent for genomic sequencing

Professionals' views on providing personalized recurrence risks for de novo mutations: Implications for genetic counseling

When an apparent de novo (new) genetic change has been identified as the cause of a serious genetic condition in a child, many couples would like to know the risk of this happening again in a future pregnancy. Current practice provides families with a population average risk of 1%-2%. However, this figure is not accurate for any specific couple, and yet, they are asked to make decisions about having another child and/or whether to have prenatal testing. The PREcision Genetic Counseling And REproduction (PREGCARE) study is a new personalized assessment strategy that refines a couple's recurrence risk prior to a new pregnancy, by analyzing several samples from the parent-child trio (blood, saliva, swabs, and father's sperm) using deep sequencing and haplotyping. Overall, this approach can reassure ~2/3 of couples who have a negligible (<0.1%) recurrence risk and focus support on those at higher risk (i.e. when mosaicism is identified in one of the parents). Here we present a qualitative interview study with UK clinical genetics professionals (n = 20), which investigate the potential implications of introducing such a strategy in genetics clinics. While thematic analysis of the interviews indicated perceived clinical utility, it also indicates a need to prepare couples for the psychosocial implications of parent-of-origin information and to support their understanding of the assessment being offered. When dealing with personalized reproductive risk, a traditional non-directive approach may not meet the needs of practitioner and client(s) and shared decision-making provides an additional framework that may relieve some patient burden. Further qualitative investigation with couples is planned.

Using a chat-based informed consent tool in large-scale genomic research

OBJECTIVE

We implemented a chatbot consent tool to shift the time burden from study staff in support of a national genomics research study.

MATERIALS AND METHODS

We created an Institutional Review Board-approved script for automated chat-based consent. We compared data from prospective participants who used the tool or had traditional consent conversations with study staff.

RESULTS

Chat-based consent, completed on a user's schedule, was shorter than the traditional conversation. This did not lead to a significant change in affirmative consents. Within affirmative consents and declines, more prospective participants completed the chat-based process. A quiz to assess chat-based consent user understanding had a high pass rate with no reported negative experiences.

CONCLUSION

Our report shows that a structured script can convey important information while realizing the benefits of automation and burden shifting. Analysis suggests that it may be advantageous to use chatbots to scale this rate-limiting step in large research projects.

'It's a nightmare': informed consent in paediatric genome-wide sequencing. A qualitative expert interview study from Germany and Switzerland

The use of genome-wide sequencing (GWS) in paediatrics has added complexity to informed consent (IC) and pretest counselling because of the vast number and interpretation of potential findings, and their implications. However, empirical data from continental Europe on these issues remains limited. This study therefore aimed to explore the experiences and views of medical geneticists working with children in Germany and Switzerland regarding the challenges of obtaining valid IC in paediatric GWS. Qualitative interviews with 20 medical geneticists were analysed employing reflexive thematic analysis. In the interviews, many medical geneticists questioned the validity of parents' IC due to the enormous amount of relevant information given and the variety and complexity of the possible test outcomes. Key barriers identified included familial implications, administrative challenges and struggles with non-directiveness. Medical geneticists' suggestions for improvement included increasing the number of genetics professionals and better information material, which is crucial as GWS becomes a diagnostic standard in the early care pathways of children. An adjustment of aspirations from still existing ideal of traditional fully IC to appropriate IC seems to be needed. Such a more realistic and ethically sound adaptation of the requirements for IC can lead to better 'informedness' and improve the validity of the consent. This might also help reduce the moral distress for the medical geneticists involved.

"Development and Implementation of Novel Chatbot-based Genomic Research Consent"

Objective

To conduct a retrospective analysis comparing traditional human-based consenting to an automated chat-based consenting process.

Materials and Methods

We developed a new chat-based consent using our IRB-approved consent forms. We leveraged a previously developed platform (GiaⓇ, or "Genetic Information Assistant") to deliver the chat content to candidate participants. The content included information about the study, educational information, and a quiz to assess understanding. We analyzed 144 families referred to our study during a 6-month time period. A total of 37 families completed consent using the traditional process, while 35 families completed consent using Gia.

Results

Engagement rates were similar between both consenting methods. The median length of the consent conversation was shorter for Gia users compared to traditional (44 vs. 76 minutes). Additionally, the total time from referral to consent completion was faster with Gia (5 vs. 16 days). Within Gia, understanding was assessed with a 10-question quiz that most participants (96%) passed. Feedback about the chat consent indicated that 86% of participants had a positive experience.

Discussion

Using Gia resulted in time savings for both the participant and study staff. The chatbot enables studies to reach more potential candidates. We identified five key features related to human-centered design for developing a consent chat.

Conclusion

This analysis suggests that it is feasible to use an automated chatbot to scale obtaining informed consent for a genomics research study. We further identify a number of advantages when using a chatbot.

The goldilocks conundrum: Disclosing discrimination risks in informed consent

Informed consent is a foundational ethical and legal principle in human subjects research and clinical care. Yet, there is extensive debate over how much information must be disclosed to meet ethical goals and legal requirements, especially about non-medical risks. In this online, survey-based experiment of a diverse sample of the US general population, we explored one aspect of this debate by testing whether the level of detail included in informed consent regarding genetic anti-discrimination protections alters individuals' willingness to participate in a hypothetical research study and their concerns regarding genetic discrimination. Participants were randomized to receive sample informed consent language with one of three levels of disclosure regarding the protections and limitations of the Genetic Information Nondiscrimination Act (GINA). Our sample (n = 1,195) had a mean age of 45.9 (SD = 17.9) years and 40% with ≤high school education. Participants were 51.3% female and 36.7% non-Hispanic White. On average, those who received consent language with none of GINA's limitations highlighted were more willing to participate than those who were warned about various gaps in GINA. They also had significantly lower perceived risk of discrimination than those presented with the most information about limitations. Our study found that providing more comprehensive information about GINA notably lessened willingness to participate in the hypothetical studies, highlighting the need for clinicians and researchers to thoughtfully consider how to disclose anti-discrimination risks in informed consent.

Parents' understanding of genome and exome sequencing for pediatric health conditions: a systematic review

Genome and exome sequencing (GS/ES) are increasingly being used in pediatric contexts. We summarize evidence regarding the actual and perceived understanding of GS/ES of parents of a child offered testing for diagnosis and/or management of a symptomatic health condition. We searched four databases (2008-2021) and identified 1264 unique articles, of which 16 met inclusion criteria. We synthesized data from qualitative and quantitative studies and organized results using Ayuso et al. (2013)'s framework of key elements of information for informed consent to GS/ES. Many of the parents represented had prior experience with genetic testing and accessed a form of genetic counseling. Parents' understanding was varied across the domains evaluated. Parents demonstrated understanding of the various potential direct clinical benefits to their child undergoing GS/ES, including in relation to other genetic tests. We found parents had mixed understanding of the nature of potential secondary findings, and of issues related to data privacy, confidentiality, and usage of sequencing results beyond their child's clinical care. Genetic counseling consultations improved understanding. Our synthesis indicates that ES/GS can be challenging for families to understand and underscores the importance of equipping healthcare professionals to explore parents' understanding of ES/GS and the implications of testing for their child.

ORCA, a values-based decision aid for selecting additional findings from genomic sequencing in adults: Efficacy results from a randomized trial

PURPOSE

Individuals having genomic sequencing can choose to be notified about pathogenic variants in genes unrelated to the testing indication. A decision aid can facilitate weighing one's values before making a choice about these additional results.

METHODS

We conducted a randomized trial (N = 231) comparing informed values-choice congruence among adults at risk for a hereditary cancer syndrome who viewed either the Optional Results Choice Aid (ORCA) or web-based additional findings information alone. ORCA is values-focused with a low-literacy design.

RESULTS

Individuals in both arms had informed values-choice congruence (75% and 73% in the decision aid and web-based groups, respectively; odds ratio [OR] = 1.10, 95% CI = 0.58-2.08). Most participants had adequate knowledge (79% and 76% in the decision aid and web-based groups, respectively; OR = 1.20, 95% CI = 0.61-2.34), with no significant difference between groups. Most had information-seeking values (97% and 98% in the decision aid and web-based groups, respectively; OR = 0.59, 95% CI = 0.10-3.61) and chose to receive additional findings.

CONCLUSION

The ORCA decision aid did not significantly improve informed values-choice congruence over web-based information in this cohort of adults deciding about genomic results. Both web-based approaches may be effective for adults to decide about receiving medically actionable additional results.

Receiving Genomic Sequencing Results through the Victorian Undiagnosed Disease Program: Exploring Parental Experiences

Rare diseases cumulatively affect a significant number of people, and for many, a diagnosis remains elusive. The Victorian Undiagnosed Disease Program (UDP-Vic) utilizes deep phenotyping, advanced genomic sequencing and functional studies to diagnose children with rare diseases for which previous clinical testing has been non-diagnostic. Whereas the diagnostic outcomes of undiagnosed disease programs have been well-described, here, we explore how parents experience participation in the UDP-Vic and the impact of receiving both diagnostic and non-diagnostic genomic sequencing results for their children. Semi-structured interviews ranging in length from 25 to 105 min were conducted with 21 parents of children in the program. Ten participants were parents of children who received a diagnosis through the program, and eleven were parents of children who remain undiagnosed. Although the experiences of families varied, five shared themes emerged from the data: (1) searching for a diagnosis, (2) varied impact of receiving a result, (3) feelings of relief and disappointment, (4) seeking connection and (5) moving towards acceptance. The findings demonstrate the shared experience of parents of children with rare disease both before and after a genomic sequencing result. The results have implications for genetic counselors and clinicians offering genomic sequencing and supporting families of children with rare diseases.

Perspectives and preferences regarding genomic secondary findings in underrepresented prenatal and pediatric populations: A mixed-methods approach

PURPOSE

Patients undergoing clinical exome sequencing (ES) are routinely offered the option to receive secondary findings (SF). However, little is known about the views of individuals from underrepresented minority pediatric or prenatal populations regarding SF.

METHODS

We explored the preferences for receiving hypothetical categories of SF (H-SF) and reasons for accepting or declining actual SF through surveying (n = 149) and/or interviewing (n = 47) 190 families undergoing pediatric or prenatal ES.

RESULTS

Underrepresented minorities made up 75% of the probands. In total, 150 families (79%) accepted SF as part of their child/fetus's ES. Most families (63%) wanted all categories of H-SF. Those who declined SF as part of ES were less likely to want H-SF across all categories. Interview findings indicate that some families did not recall their SF decision. Preparing for the future was a major motivator for accepting SF, and concerns about privacy, discrimination, and psychological effect drove decliners.

CONCLUSION

A notable subset of families (37%) did not want at least 1 category of H-SF, suggesting more hesitancy about receiving all available results than previously reported. The lack of recollection of SF decisions suggests a need for alternative communication approaches. Results highlight the importance of the inclusion of diverse populations in genomic research.

Preference for secondary findings in prenatal and pediatric exome sequencing

OBJECTIVE

We aimed to determine the frequency of accepting secondary findings in families undergoing exome sequencing in prenatal and pediatric settings.

METHODS

This was a secondary analysis of prospectively enrolled patients undergoing trio exome sequencing for congenital anomalies or developmental disorders in prenatal and pediatric settings, in which families were offered receiving secondary findings (initially assessed in the proband and, if identified, then in the parents). The primary outcome was frequency of accepting secondary findings. Secondary outcomes included frequency of acceptance in prenatal versus pediatric settings, and sociodemographic differences between those who accepted versus declined secondary findings.

RESULTS

There were 682 families included in the cohort (289 prenatal and 393 pediatric). Overall, 84% (576/682) of families accepted secondary findings: 86.2% (249/289) of families undergoing prenatal versus 83.2% (327/393) pediatric (p = 0.30) testing. Secondary findings were identified in 2.6% (15/576) of cases, with no difference between prenatal and pediatric settings. There were no differences in sociodemographics between families that accepted versus declined secondary findings.

CONCLUSION

The majority of families undergoing exome sequencing accepted secondary findings; this did not differ in prenatal versus pediatric settings. This highlights the need for guidance surrounding the offer of secondary findings in the prenatal setting.

Informed consent practices for exome sequencing: An interview study with clinical geneticists in the Netherlands

BACKGROUND

Genomic sequencing is being used more frequently in the clinic, not only by clinical geneticists, but also by other specialists ("mainstreaming"). The use of genomic sequencing gives rise to challenges regarding informed consent, as it can yield more, and more complex results.

METHODS

This study maps the informed consent process for exome sequencing in the Netherlands by means of semistructured interviews with 14 clinical geneticists. Interviewees were asked about their strategies for informing patients about exome sequencing and supporting patients in their decision making, about what they think of as essential information elements, about the challenges they experience, and about their preferences for future policy and practice.

RESULTS

Clinical geneticists typically discuss the following topics: the nature and aim of the test, the possible results (including unsolicited or incidental findings and Variants of Uncertain Significance) of the test and the consequences of those results for the patient and their family members. Some clinical geneticists use a layered approach to informed consent, meaning that they give short and concise information at first, and provide more detailed information depending on the situation or the needs of the patient.

CONCLUSION

During pre-test counseling for genomic sequencing, clinical geneticists use various strategies to enhance patient understanding and personalization of the informed consent process. Going forward, layering information may be part of a solution to ethical challenges of informed consent, also in mainstream settings.

Misattributed parentage identified through diagnostic exome sequencing: Frequency of detection and reporting practices

Access to genetic testing, namely, diagnostic exome sequencing (DES), has significantly improved, subsequently increasing the likelihood of discovering incidental findings, such as misattributed relationships and specifically misattributed parentage (MP). Until the recently published ACMG statement, there had been no consensus for laboratories and clinicians to follow when addressing such findings. Family-based genomic testing is valuable for accurate variant interpretation but has the potential to uncover misattributed familial relationships. Here, we present the first published data on the frequency of MP identified through DES at a clinical laboratory. We also investigated clinicians' decisions on how to proceed with analysis, reporting, and disclosure. A database of 6,752 families who underwent parent-proband ('trio') DES was retrospectively reviewed for molecular identification of MP and clinicians' MP disclosure decisions. Among 6,752 trios, 39 cases of MP were detected (0.58%). Non-paternity was detected in all cases, and in one instance, non-maternity was also identified. All clinicians decided to proceed by omitting the MP individual from the analysis. Clinicians chose to proceed with duo analysis (87.2%), modify information on the report (74.4%), and communicate MP results to the mother (71.8%), suggesting a trend toward not disclosing to the putative father or proband. The data show that trio DES involves a chance of detecting MP and that clinician disclosure practices do not appear to routinely include direct disclosure to the putative father. MP identified in our parent-proband trios sent in for DES is lower than the reported frequency of MP in the general population due in part to ascertainment bias as families with known or suspected MP are presumably less likely to pursue trio testing. These data may inform laboratory policies and clinician practices for addressing incidental findings such as MP.

Mixed-methods evaluation of the NHS Genomic Medicine Service for paediatric rare diseases: study protocol

Background

A new nationally commissioned NHS England Genomic Medicine Service (GMS) was recently established to deliver genomic testing with equity of access for patients affected by rare diseases and cancer. The overarching aim of this research is to evaluate the implementation of the GMS during its early years, identify barriers and enablers to successful implementation, and provide recommendations for practice. The focus will be on the use of genomic testing for paediatric rare diseases.

Methods

This will be a four-year mixed-methods research programme using clinic observations, interviews and surveys. Study 1 consists of qualitative interviews with designers/implementers of the GMS in Year 1 of the research programme, along with documentary analysis to understand the intended outcomes for the Service. These will be revisited in Year 4 to compare intended outcomes with what happened in practice, and to identify barriers and facilitators that were encountered along the way. Study 2 consists of clinic observations (pre-test counselling and results disclosure) to examine the interaction between health professionals and parents, along with follow-up interviews with both after each observation. Study 3 consists of a longitudinal survey with parents at two timepoints (time of testing and 12 months post-results) along with follow-up interviews, to examine parent-reported experiences and outcomes. Study 4 consists of qualitative interviews and a cross-sectional survey with medical specialists to identify preparedness, facilitators and challenges to mainstreaming genomic testing. The use of theory-based and pre-specified constructs will help generalise the findings and enable integration across the various sub-studies.

Dissemination

We will disseminate our results to policymakers as findings emerge, so any suggested changes to service provision can be considered in a timely manner. A workshop with key stakeholders will be held in Year 4 to develop and agree a set of recommendations for practice.

Elicitation of children's understanding of information in pediatric genetic counseling encounters: A discourse-oriented perspective

Affirmation of children's understanding of information provided in genetic counseling encounters is crucial to obtaining children's informed consent/assent in pediatric genetic counseling encounters. It is also important for the proper management of a genetic condition. Currently, there is a relative scarcity of research on how understanding of complex genetic information by children is elicited in the process of pediatric genetic counseling. In this study, we apply theme-oriented discourse analysis to examine 23 video/audio-recorded genetic counseling encounters in Hong Kong. The encounters involve children aged between 3 and 17 years old who are suspected to have or diagnosed with Sudden Arrhythmic Death Syndrome (SADS). Specifically, we examine a range of communicative strategies that genetic professionals employ to elicit children's understanding of information in this genetic counseling setting. We also examine how children's epistemic status is negotiated between genetic professionals, parents, and children. The study reveals that genetic professionals typically use direct questioning (e.g., "do you understand?" or "do you have any questions?"). Less typical are examples where genetic professionals explore children's epistemic access and invite children to recall information after they deliver it. The study reveals two discourse strategies that genetic professionals and parents employ to justify a child's low epistemic status: (1) construction of "current ignorance" and "future competence" in children and (2) association with a child's character. In the examined counseling encounters, genetic professionals and parents tend to construct a low epistemic status in younger children and allocate the responsibility for understanding relevant information to the parents and the "future" competent children. The study highlights the impact of genetic professionals' and parents' assumptions on children's knowledge and comprehensibility at different ages, and the role that children themselves play in conforming or contesting these assumptions.

Return of individual research results from genomic research: A systematic review of stakeholder perspectives

Despite the plethora of empirical studies conducted to date, debate continues about whether and to what extent results should be returned to participants of genomic research. We aimed to systematically review the empirical literature exploring stakeholders’ perspectives on return of individual research results (IRR) from genomic research. We examined preferences for receiving or willingness to return IRR, and experiences with either receiving or returning them. The systematic searches were conducted across five major databases in August 2018 and repeated in April 2020, and included studies reporting findings from primary research regardless of method (quantitative, qualitative, mixed). Articles that related to the clinical setting were excluded. Our search identified 221 articles that met our search criteria. This included 118 quantitative, 69 qualitative and 34 mixed methods studies. These articles included a total number of 118,874 stakeholders with research participants (85,270/72%) and members of the general public (40,967/35%) being the largest groups represented. The articles spanned at least 22 different countries with most (144/65%) being from the USA. Most (76%) discussed clinical research projects, rather than biobanks. More than half (58%) gauged views that were hypothetical. We found overwhelming evidence of high interest in return of IRR from potential and actual genomic research participants. There is also a general willingness to provide such results by researchers and health professionals, although they tend to adopt a more cautious stance. While all results are desired to some degree, those that have the potential to change clinical management are generally prioritized by all stakeholders. Professional stakeholders appear more willing to return results that are reliable and clinically relevant than those that are less reliable and lack clinical relevance. The lack of evidence for significant enduring psychological harm and the clear benefits to some research participants suggest that researchers should be returning actionable IRRs to participants.

Return of Results Policies for Genomic Research: Current Practices & The Hearts in Rhythm Organization Approach

Research teams developing biobanks and/or genomic databases must develop policies for the disclosure and reporting of potentially actionable genomic results to research participants. Currently, a broad range of approaches to the return of results exist, with some studies opting for non-disclosure of research results while others follow clinical guidelines for the return of potentially actionable findings from sequencing. In this review, we describe current practices and highlight decisions a research team must make when designing a return of results policy, from informed consent to disclosure practices and clinical validation options. The unique challenges of returning incidental findings in cardiac genes, including reduced penetrance and the lack of clinical screening standards for phenotype-negative individuals are discussed. Lastly, the National Hearts in Rhythm Organization (HiRO) Registry approach is described to provide a rationale for the selective return of field-specific variants to those participating in disease-specific research. Our goal is to provide researchers with a resource when developing a return of results policy tailored for their research program, based on unique factors related to study design, research team composition and availability of clinical resources.

Animation or leaflet: Does it make a difference when educating young people about genome sequencing?

OBJECTIVE

To compare the effectiveness of an animation against two leaflets with and without images, in educating young people about genome sequencing (GS).

METHODS

An experimental survey with three assessment points (pre- intervention [T1], post - intervention [T2], 6-week follow-up [T3]). Participants (N = 606) were randomly assigned to receive one of three educational interventions; animation (n = 212); leaflet with images (n = 197); or leaflet with text only (n = 197). Measures of objective and subjective knowledge were completed at T1 (N = 606), T2 (N = 606) and T3 (N = 459). Measures of attitudes, intentions and beliefs towards GS and satisfaction with intervention were completed at T2 only.

RESULTS

The type of educational intervention young people received had no significant impact on their objective or subjective knowledge at both T2 and T3 (all p > .05), nor did the educational intervention type affect their attitudes, intentions and beliefs towards GS at T2 (p > .05). However, participant satisfaction was significantly higher in the animation group than the leaflet groups (p < .001).

CONCLUSION

Animations and leaflets are both effective ways to deliver genomic education to young people, but the animations lead to higher satisfaction.

PRACTICE IMPLICATIONS

Different individuals may find different modes of educational resources more accessible than others. Therefore a range of resources should ideally be made available to patients.

An evaluation of the process of informed consent: views from research participants and staff

Background

The process of informed consent for enrolment to a clinical research study can be complex for both participants and research staff. Challenges include respecting the potential participant’s autonomy and information needs while simultaneously providing adequate information to enable an informed decision. Qualitative research with small sample sizes has added to our understanding of these challenges. However, there is value in garnering the perspectives of research participants and staff across larger samples to explore the impact of contextual factors (time spent, the timing of the discussion and the setting), on the informed consent process.

Methods

Research staff and research participants from Ireland and the UK were invited to complete an anonymous survey by post or online (research participants) and online (research staff). The surveys aimed to quantify the perceptions of research participants and staff regarding some contextual factors about the process of informed consent. The survey, which contained 14 and 16 multiple choice questions for research participants and staff respectively, was analysed using descriptive statistics. Both surveys included one optional, open-ended question, which were analysed thematically.

Results

Research participants (169) and research staff (115) completed the survey. Research participants were predominantly positive about the informed consent process but highlighted the importance of having sufficient time and the value of providing follow-up once the study concludes, e.g. providing results to participants. Most staff (74.4%) staff reported that they felt very confident or confident facilitating informed consent discussions, but 63% felt information leaflets were too long and/or complicated, 56% were concerned about whether participants had understood complex information and 40% felt that time constraints were a barrier. A dominant theme from the open-ended responses to the staff survey was the importance of adequate time and resources.

Conclusions

Research participants in this study were overwhelmingly positive about their experience of the informed consent process. However, research staff expressed concern about how much participants have understood and studies of patient comprehension of research study information would seem to confirm these fears. This study highlights the importance of allocating adequate time to informed consent discussions, and research staff could consider using Teach Back techniques.

GeneLiFT: A novel test to facilitate rapid screening of genetic literacy in a diverse population undergoing genetic testing

With the broader introduction of genomic medicine in research and clinical care, an increasing number of persons are offered genetic testing. Many factors, including genetic literacy, may impact the utilization of genetic results by patients and their families. We developed a rapid, self-administered measure of genetic literacy, called Genetic Literacy Fast Test (GeneLiFT). We next evaluated the association of GeneLiFT scores with the comprehension of limitations of genomic medicine in participants undergoing genetic testing in the NIH-sponsored eMERGE III study at Columbia University Irving Medical Center, New York. All participants underwent genetic screening for variants in 74 actionable genes associated with adult-onset disorders. A diverse cohort of 724 participants completed the survey (60% women, 45% less than 40 years old, and 53% self-reported White non-Hispanic ancestry). The GeneLiFT was validated using known group differences based on education, health literacy, and numeracy, and with questions assessing genetic knowledge. GeneLiFT identified multiple standard genetics terms, that is, jargon, not recognized by more than 50% of participants (including actionability and pathogenicity). Low genetic literacy, identified in 210 participants (29%), was significantly associated with poor understanding of the limitations of genetic testing (p-values < 10-9 ). This association was independent of education, health literacy, and numeracy levels, highlighting the importance of directly measuring genetic literacy. Low genetic literacy was also associated with low satisfaction with the informed consent process. GeneLiFT is a practical tool for rapid assessment of genetic literacy in large studies or clinical care. GeneLiFT will allow future research to efficiently assess the role of genetic literacy on the clinical impact of genetic testing.

Identifying Aspects of Public Attitudes Toward Whole Genome Sequencing to Inform the Integration of Genomics into Care

INTRODUCTION

The growth of global sequencing initiatives and commercial genomic test offerings suggests the public will increasingly be confronted with decisions about sequencing. Understanding public attitudes can assist efforts to integrate sequencing into care and inform the development of public education and outreach strategies.

METHODS

A 48-item online survey was advertised on Facebook in Eastern Canada and hosted on SurveyMonkey in late 2018. The survey measured public interest in whole genome sequencing and attitudes toward various aspects of sequencing using vignettes, scaled, and open-ended items.

RESULTS

While interest in sequencing was high, critical attitudes were observed. In particular, items measuring features of patient control and choice regarding genomic data were strongly endorsed by respondents. Majority wanted to specify upfront how their data could be used, retain the ability to withdraw their sample at a later date, sign a written consent form, and speak to a genetic counselor prior to sequencing. Concerns about privacy and unauthorized access to data were frequently observed. Education level was the sociodemographic variable most often related to attitude statements such that those with higher levels of education generally displayed more critical attitudes.

CONCLUSIONS

Attitudes identified here could be used to inform the development of implementation strategies for genomic medicine. Findings suggest health systems must address patient concerns about privacy, consent practices, and the strong desire to control what happens to their genomic data through public outreach and education. Specific oversight procedures and policies that are clearly communicated to the public will be required.

Introducing Edna: A trainee chatbot designed to support communication about additional (secondary) genomic findings

OBJECTIVE

To support informed decision-making about reanalysis of clinical genomic data for risk of preventable conditions ('additional findings') by developing a chatbot (electronic genetic resource, 'eDNA').

METHODS

Interactions in pre-test genetic counseling sessions (13.5 h) about additional findings were characterized using proponent, thematic and semantic analyses of transcripts. We then wrote interfaces to draw supplementary data from external genetics applications. To create Edna, this content was programmed using a chatbot framework which interacts with patients via speech-to-text.

RESULTS

Conditions, terms, explanations of concepts, and key factors to consider in decision making were all encoded into chatbot conversations emulating counseling session flows. Patient agency can be enhanced by prompted consideration of the personal and familial implications of testing. Similarly, health literacy can be broadened through explanation of genetic conditions and terminology. Novel aspects include sentiment analysis and collection of family history. Medical advice and the impact of existing genetic conditions were deemed inappropriate for inclusion.

CONCLUSION

Edna's successful development represents a movement towards accessible, acceptable and well-supported digital health processes for patients to make informed decisions for additional findings.

PRACTICE IMPLICATIONS

Edna complements genetic counseling by collecting and providing genomic information before or after pre-test consultations.

Mainstreaming informed consent for genomic sequencing: A call for action

The wider availability of genomic sequencing, notably gene panels, in cancer care allows for personalised medicine or the tailoring of clinical management to the genetic characteristics of tumours. While the primary aim of mainstream genomic sequencing of cancer patients is therapy-focussed, genomic testing may yield three types of results beyond the answer to the clinical question: suspected germline mutations, variants of uncertain significance (VUS), and unsolicited findings pertaining to other conditions. Ideally, patients should be prepared beforehand for the clinical and psychosocial consequences of such findings, for themselves and for their family members, and be given the opportunity to autonomously decide whether or not to receive such unsolicited genomic information. When genomic tests are mainstreamed into cancer care, so should accompanying informed consent practices. This paper outlines what mainstream oncologists may learn from the ethical tradition of informed consent for genomic sequencing, as developed within clinical genetics. It argues that mainstream informed consent practices should focus on preparing patients for three types of unsolicited outcomes, briefly and effectively. Also, it argues that when the chance of unsolicited findings is very low, opt-out options need not be actively offered. The use of a layered approach - integrated in information systems - should render informed consent feasible for non-geneticist clinicians in mainstream settings. (Inter) national guidelines for mainstreaming informed consent for genomic sequencing must be developed.

Genomic Sequencing Results Disclosure in Diverse and Medically Underserved Populations: Themes, Challenges, and Strategies from the CSER Consortium

Genomic sequencing results need to be effectively communicated across all populations and practice settings. Projects in the Clinical Sequencing Evidence-Generating Research (CSER) consortium enroll diverse racial/ethnic and medically underserved participants across various clinical contexts. This article explores a set of CSER results disclosure cases to expand the evidence base on experiences returning genomic results. Case details were collected using a structured set of questions. We identified common themes in the case set, and assessed challenges and strategies in achieving six relevant results disclosure objectives. CSER-affiliated patient/community stakeholder impressions of the findings were solicited via video conference calls. Seventeen cases across six CSER projects were included. Case themes sorted into four categories: (1) factors influencing participant understanding, (2) participant emotional response, (3) disease burden, and (4) logistical challenges. Challenges meeting results disclosure objectives included a lack of dialogue, health literacy level, unexpected findings, and complex concepts. Strategies were consistent with traditional genetic counseling practice, but also highlighted approaches being evaluated in CSER projects. Patient/community stakeholders supported the identified themes and provided additional suggestions to improve patient understanding and engagement. These experiences add valuable insights into adapting genomic results disclosure practices to best serve all patient populations.

The role of digital tools in the delivery of genomic medicine: enhancing patient-centered care

PURPOSE

Alternative models of genetic counseling are needed to meet the rising demand for genomic sequencing. Digital tools have been proposed as a method to augment traditional counseling and reduce burden on professionals; however, their role in delivery of genetic counseling is not established. This study explored the role of the Genomics ADvISER, a digital decision aid, in delivery of genomic counseling.

METHODS

We performed secondary analysis of 52 pretest genetic counseling sessions that were conducted over the course of a randomized controlled trial evaluating the effectiveness of the Genomics ADvISER. As part of the trial, participants were randomized to receive standard counseling or use the tool and then speak with a counselor. A qualitative interpretive description approach using thematic analysis and constant comparison was used for analysis.

RESULTS

In the delivery of genomic counseling, the Genomics ADvISER contributed to enhancing counseling by (1) promoting informed dialogue, (2) facilitating preference-sensitive deliberation, and (3) deepening personalization of decisions, all of which represent fundamental principles of patient-centered care: providing clear high-quality information, respecting patients' values, preferences, and expressed needs, and providing emotional support.

CONCLUSION

This study demonstrates that our digital tool contributed to enhancing patient-centered care in the delivery of genomic counseling.

The ethical implications of genetic testing in neurodegenerative diseases: A systematic review

BACKGROUND

Availability of genetic testing in neurodegenerative disorders has developed rapidly. This growing ability is providing specific genetic information to individuals and, in turn, their families, raising ethical concerns. However, family members' perspective is a seldom-studied phenomenon.

AIM

The aim of this systematic review was to describe the ethical aspect of genetic testing in neurodegenerative diseases from the perspective of at-risk family members.

METHOD

A systematic review of data was performed in accordance with the PRISMA statement. The data search was conducted using the CINAHL, PubMed and Scopus databases to identify original peer-reviewed studies published between January 2009 and April 2019. A total of 24 articles were selected. The data were analysed using inductive content analysis.

FINDINGS

On the basis of the analysis, four central ethical implications were identified: (i) decision-making in genetic testing as a dilemma: balance between autonomy and responsibility, (ii) the individual's right to make a voluntary and informed decision for genetic testing, (iii) conflicting emotions after knowing one's genetic status and (iv) privacy and confidentiality of genetic information: the fear of genetic discrimination and stigma.

CONCLUSIONS

The findings of this review increase understanding about the central ethical implications of genetic testing in neurodegenerative diseases from the perspective of family members, and identify and underline outstanding needs for further research.

Informed Consent for Genetic and Genomic Research

Genetic research often utilizes or generates information that is potentially sensitive to individuals, families, or communities. For these reasons, genetic research may warrant additional scrutiny from investigators and governmental regulators, compared to other types of biomedical research. The informed consent process should address the range of social and psychological issues that may arise in genetic research. This article addresses a number of these issues, including recruitment of participants, disclosure of results, psychological impact of results, insurance and employment discrimination, community engagement, consent for tissue banking, and intellectual property issues. Points of consideration are offered to assist in the development of protocols and consent processes in light of contemporary debates on a number of these issues. © 2020 Wiley Periodicals LLC.

Old Challenges or New Issues? Genetic Health Professionals' Experiences Obtaining Informed Consent in Diagnostic Genomic Sequencing

Background

While integrating genomic sequencing into clinical care carries clear medical benefits, it also raises difficult ethical questions. Compared to traditional sequencing technologies, genomic sequencing and analysis is more likely to identify unsolicited findings (UF) and variants that cannot be classified as benign or disease-causing (variants of uncertain significance; VUS). UF and VUS pose new challenges for genetic health professionals (GHPs) who are obtaining informed consent for genomic sequencing from patients.

Methods

We conducted semi-structured interviews with 31 GHPs across Europe, Australia and Canada to identify some of these challenges.

Results

Our results show that GHPs find it difficult to prepare patients to receive results because a vast amount of information is required to fully inform patients about VUS and UF. GHPs also struggle to engage patients – many of whom may be focused on ending their ‘diagnostic odyssey’ – in the informed consent process in a meaningful way. Thus, some questioned how ‘informed’ patients actually are when they agree to undergo clinical genomic sequencing.

Conclusions

These findings suggest a tension remains between sufficient information provision at the risk of overwhelming the patient and imparting less information at the risk of uninformed decision-making. We suggest that a shift away from ‘fully informed consent’ toward an approach aimed at realizing, as far as possible, the underlying goals that informed consent is meant to promote.

Informed Consent in the Genomics Era

Informed consent, the process of gathering autonomous authorization for a medical intervention or medical research participation, is a fundamental component of medical practice. Medical informed consent assumes decision-making capacity, voluntariness, comprehension, and adequate information. The increasing use of genetic testing, particularly genomic sequencing, in clinical and research settings has presented many new challenges for clinicians and researchers when obtaining informed consent. Many of these challenges revolve around the need for patient comprehension of sufficient information. Genomic sequencing is complex-all of the possible results are too numerous to explain, and many of the risks and benefits remain unknown. Thus, historical standards of consent are difficult to apply. Alternative models of consent have been proposed to increase patient understanding, and several have empirically demonstrated effectiveness. However, there is still a striking lack of consensus in the genetics community about what constitutes informed consent in the context of genomic sequencing. Multiple approaches are needed to address this challenge, including consensus building around standards, targeted use of genetic counselors in nongenetics clinics in which genomic testing is ordered, and the development and testing of alternative models for obtaining informed consent.

Parental experiences of ultrarapid genomic testing for their critically unwell infants and children

PURPOSE

To explore parental experiences of ultrarapid genomic testing for their critically unwell infants and children.

METHODS

Parents of critically unwell children who participated in a national ultrarapid genomic diagnosis program were surveyed >12 weeks after genomic results return. Surveys consisted of custom questions and validated scales, including the Decision Regret Scale and Genomics Outcome Scale.

RESULTS

With 96 survey invitations sent, the response rate was 57% (n = 55). Most parents reported receiving enough information during pretest (n = 50, 94%) and post-test (n = 44, 83%) counseling. Perceptions varied regarding benefits of testing, however most parents reported no or mild decision regret (n = 45, 82%). The majority of parents (31/52, 60%) were extremely concerned about the condition recurring in future children, regardless of actual or perceived recurrence risk. Parents whose child received a diagnostic result reported higher empowerment.

CONCLUSION

This study provides valuable insight into parental experiences of ultrarapid genomic testing in critically unwell children, including decision regret, empowerment, and post-test reproductive planning, to inform design and delivery of rapid diagnosis programs. The findings suggest considerations for pre- and post-test counseling that may influence parental experiences during the testing process and beyond, such as the importance of realistically conveying the likelihood for clinical and/or personal utility.

Experiences and lessons learned by genetic counselors in returning secondary genetic findings to patients

Few studies have explored the real-world experiences and strategies of genetic counselors involved in the process of returning secondary findings (SFs). This study aimed to describe and categorize the experiences for the return of SFs from clinical sequencing. Semi-structured telephone interviews with 21 genetic counselors representing 56 incidences were conducted. A content analysis was conducted on the transcripts through an iterative, team-based approach. Four common categories emerged across all interviews. These included (a) the importance of pretest counseling for the return of SFs, (b) how primary test results influenced the level of importance placed on the SFs, (c) patients' emotional reactions from receiving SF results, and (d) how returning SFs changed future pretest counseling and consent. This study identified experiences and common practices by genetic counselors who returned SFs. More research is needed to assess how genetic counselors' specific strategies improve patient comprehension and medical actions.

Shortened consent forms for genome-wide sequencing: Parent and provider perspectives

BACKGROUND

Consent forms for exome and/or genome sequencing, collectively called genome-wide sequencing (GWS), frequently contain detailed information on complex topics such as sequencing analysis and incidental findings. Considering recent endeavors by the health care community to simplify GWS consent forms, it is important to gain stakeholders' perspectives on the content, length, and use of consent forms.

METHODS

Thematic analysis was conducted on data obtained from focus groups with two participant cohorts: parents who previously provided consent for trio-based GWS as part of the translational pediatric GWS CAUSES Study, and genetic health care providers (HCP) who provide pre-test counseling for GWS.

RESULTS

Genetic HCP indicated that consent forms cannot replace pre-test counseling, and as such, a simplified consent form focusing on the implications of GWS would be beneficial to both patients and HCP. Although parents' primary concerns varied when considering GWS, they all highly valued information. Parents also indicated the need for community and support after the return of GWS results. Both participant cohorts recommended that consent forms be available online and include an appendix for supplementary information.

CONCLUSION

It is important to include both parents and HCP in the design of GWS consent forms, and also, to help connect families who have a shared diagnosis after the post-test counseling session.

Implementation of Common Rule Changes to the Informed Consent Form: A Research Staff and Institutional Review Board Collaboration

Background: The Common Rule, which governs federally funded clinical research involving human subjects, formally defines the requirements for institutional review board (IRB) membership, functions and operations, and review of research, as well as the requirements for obtaining informed consent from research participants. The revisions to the Common Rule effective in January 2019 changed some content requirements for informed consent forms.

Methods: This article summarizes the history of informed consent requirements, the changes made to the requirements by the revision to the Common Rule, and the ways in which IRBs and research staff work together to develop informed consent forms that comply with the regulations and provide all the information potential research subjects need to decide whether to participate in a study.

Results: Clinical research coordinators, under their investigators’ supervision, are responsible for ensuring that research consent forms comply with the requirements of the federal regulations and the institution. Many IRBs have provided education regarding these new requirements, as well as consent templates that contain all the required elements. To ensure that the Common Rule's requirements are met, the IRB reviews each study submission, including the consent form. The IRB panel makes revisions to the consent forms as needed and returns the approved consent form to the investigator and clinical research coordinator.

Conclusion: Research coordinators play an essential role in developing consent forms and providing the required review information to the IRB. In turn, through optimizing and standardizing consent forms and ensuring that all requirements of the Common Rule are followed, IRBs ensure that the rights of participants are protected and upheld.

Parents' perceptions of personal utility of exome sequencing results

PURPOSE

Clinical genome or exome sequencing (GS/ES) provides a diagnosis for many individuals with suspected genetic disorders, but also yields negative or uncertain results for the majority. This study examines how parents of a child with an undiagnosed condition attribute personal utility to all types of ES results.

METHODS

Return of 31 exome sequencing results was observed during clinic sessions, followed by semistructured interviews with parents one month later. Observations and interviews were recorded and transcribed. Data display matrices were used for content analysis and systematic comparisons of parents' perceptions of utility.

RESULTS

ES results could not provide all the answers to parents' questions, especially in cases of clinically uninformative results, but parents nonetheless attributed utility to the knowledge gained. Parents across all results categories used the genomic information to rule out possible causes, end or postpone the diagnostic odyssey, and shift focus to treatment and management of symptoms.

CONCLUSION

This study suggests that parents value even uninformative ES results while expressing hope for future discoveries. As pediatric genetics moves toward GS/ES as a first-tier test, how parents perceive the personal utility of negative or uncertain results is an important topic for genetic counseling and further research.

Parents' motivations, concerns and understanding of genome sequencing: a qualitative interview study

The 100,000 Genomes Project is a hybrid clinical and research project in which patients and parents are offered genome sequencing for cancer and rare and inherited disease diagnosis; all participants receive their main findings and contribute their data for research, and are offered optional secondary findings. Our aim was to explore participating parents' attitudes towards and understanding of genome sequencing in this hybrid context. We conducted in-depth telephone interviews with 20 parents of children with rare diseases participating in the 100,000 Genomes Project. Parents were positive about contributing to research, although some had needed reassurance about data protections. Although most felt positive about secondary findings, some could not recall or misunderstood key aspects. Some were also concerned about potential emotional impact of results and a few raised concerns about life insurance implications, and the impact of future legal changes. Participants were generally positive about consent appointments, but several raised concerns about 'information overload' because of deciding about secondary findings at the same time as about the main diagnostic genome sequencing and data contribution. Additional information resources, particularly online tools, were highlighted as potentially useful ways of supporting the consent process. We conclude that parents offered genome sequencing as part of a national hybrid clinical and research project report many positive attitudes and experiences, but also concerns and misunderstandings. Further research is needed on how best to support informed consent, particularly about secondary findings. Additional resources such as online tools might usefully support future genome sequencing consent processes.

Revised Common Rule Changes to the Consent Process and Consent Form

Background: The Federal Policy for the Protection of Human Subjects-the Common Rule-was revised in 2017 to reduce administrative burdens for low-risk research while enhancing protections for human subjects enrolled in greater-than-minimal-risk trials. These enhanced protections involve changes to the consent process. Methods: We review the general requirements applicable to the consent process, as well as the additional elements of consent mandated by the revisions to the Common Rule. The regulations apply to federally funded studies and are optional for non-federally funded studies. Results: Two new general requirements for the consent process, one basic required element for the consent form, and three optional additional elements for the consent form were added in an effort to improve potential subjects' understanding of research studies and to facilitate the exchange of information between the research staff and potential subjects. Important information about the study should be extracted into a concise key information section to help potential subjects make informed decisions regarding participation. Conclusion: The revisions to the Common Rule are intended to enhance human subject protection by providing more information in an understandable form during the consent process. The new consent elements aim to increase transparency and help improve clarity.

Best Practices for Obtaining Genomic Consent in Pediatric Traumatic Brain Injury Research

BACKGROUND

Precision health relies on large sample sizes to ensure adequate power, generalizability, and replicability; however, a critical first step to any study is the successful recruitment of participants.

OBJECTIVES

This study seeks to explore how the enrollment strategies used in a parent study contributed to the high consent rates, establish current best practices that can be used in future studies, and identify additional factors that contribute to consent into pediatric traumatic brain injury biobanks.

METHODS

Retrospective secondary analysis of data from a parent study with high consent rates was examined to explore factors affecting consent into biobanking studies.

RESULTS

Of the 76 subjects who were approached, met the eligibility criteria, and reviewed the consent form, only 16 (21.1%) declined to participate. The consented group (n = 60) represents 64.5% of those who met the eligibility criteria upon initial screening (n = 93) and 78.9% of those with confirmed eligibility (n = 76). Analysis of screening data suggested there were no major barriers to consenting individuals into this pediatric traumatic brain injury biobank.

DISCUSSION

There were no demographic or research-related characteristics that significantly explained enrollment. Ethically, to obtain true informed consent, parents need to understand only their child's diagnosis, prognosis, and medical care, as well as the purpose of the proposed research and its risks and benefits. Researchers need to implement best practices, including a comprehensive review of census data to identify eligible participants to approach, a prescreening protocol, and effective consenting process to obtain informed consent so that precision care initiatives can be pursued.

Delivering genome sequencing in clinical practice: an interview study with healthcare professionals involved in the 100 000 Genomes Project

OBJECTIVES

Genome sequencing is poised to be incorporated into clinical care for diagnoses of rare diseases and some cancers in many parts of the world. Healthcare professionals are key stakeholders in the clinical delivery of genome sequencing-based services. Our aim was to explore views of healthcare professionals with experience of offering genome sequencing via the 100 000 Genomes Project.

DESIGN

Interview study using thematic analysis.

SETTING

Four National Health Service hospitals in London.

PARTICIPANTS

Twenty-three healthcare professionals (five genetic clinicians and eight non-genetic clinicians (all consultants), and 10 'consenters' from a range of backgrounds) involved in identifying or consenting patients for the 100 000 Genomes Project.

RESULTS

Most participants expressed positive attitudes towards genome sequencing in terms of improved ability to diagnose rare diseases, but many also expressed concerns, with some believing its superiority over exome sequencing had not yet been demonstrated, or worrying that non-genetic clinicians are inadequately prepared to discuss genome sequencing results with patients. Several emphasised additional evidence about utility of genome sequencing in terms of both main and secondary findings is needed. Most felt non-genetic clinicians could support patients during consent, as long as they have appropriate training and support from genetic teams. Many stated genetics experts will play a vital role in training and supporting non-genetic clinicians in variant interpretation and results delivery, particularly for more complex cases.

CONCLUSIONS

Healthcare professionals responsible for delivering clinical genome sequencing have largely positive views about the potential for genome sequencing to improve diagnostic yield, but also significant concerns about practical aspects of offering these tests. Non-genetic clinicians delivering genome sequencing require guidance and support. Additional empirical evidence is needed to inform policy and practice, including how genome compares to exome sequencing; utility of secondary findings; training, in particular of non-genetic health professionals; and mechanisms whereby genetics teams can offer appropriate support to their non-genetics colleagues.

Challenges to informed consent for exome sequencing: A best-worst scaling experiment

As exome sequencing expands as a diagnostic tool, patients and providers have voiced concerns about communicating the breadth and scope of potential results when obtaining informed consent. This study aimed to understand how genetic counselors prioritize essential components of the informed consent process and whether counselor factors influence these decisions. Development of a best-worst scaling experiment was informed by a systematic literature review and two focus groups. In all, 11 choice sets were created using a balanced incomplete block design, where participants selected the most and least important object in each set. Mean best-worst (BW) scores were calculated to summarize the relative importance of each object, and mediation analyses assessed whether responses were associated with genetic counselor factors and attitudes. In all, 342 members of the National Society of Genetic Counselors completed the online survey. Ranking of BW scores suggests that participants prioritize collaborative decision-making, assessing understanding and managing expectations, with the least emphasis placed on discussing technological complexities. Stratified analyses found that counselors more experienced with obtaining informed consent for exome sequencing and those reporting higher perceptions of patients' ability to manage information rated discussing variants of uncertain significance as significantly more important (p < .05). Our results suggest that genetic counselors report intentions to prioritize individual patient needs when obtaining informed consent for exome sequencing. Professional characteristics and attitudes may influence preemptive discussion of uncertain results.

Model consent clauses for rare disease research

Background

Rare Disease research has seen tremendous advancements over the last decades, with the development of new technologies, various global collaborative efforts and improved data sharing. To maximize the impact of and to further build on these developments, there is a need for model consent clauses for rare diseases research, in order to improve data interoperability, to meet the informational needs of participants, and to ensure proper ethical and legal use of data sources and participants’ overall protection.

Methods

A global Task Force was set up to develop model consent clauses specific to rare diseases research, that are comprehensive, harmonized, readily accessible, and internationally applicable, facilitating the recruitment and consent of rare disease research participants around the world. Existing consent forms and notices of consent were analyzed and classified under different consent themes, which were used as background to develop the model consent clauses.

Results

The IRDiRC-GA4GH MCC Task Force met in September 2018, to discuss and design model consent clauses. Based on analyzed consent forms, they listed generic core elements and designed the following rare disease research specific core elements; Rare Disease Research Introductory Clause, Familial Participation, Audio/Visual Imaging, Collecting, storing, sharing of rare disease data, Recontact for matching, Data Linkage, Return of Results to Family Members, Incapacity/Death, and Benefits.

Conclusion

The model consent clauses presented in this article have been drafted to highlight consent elements that bear in mind the trends in rare disease research, while providing a tool to help foster harmonization and collaborative efforts.

Genomic knowledge in the context of diagnostic exome sequencing: changes over time, persistent subgroup differences, and associations with psychological sequencing outcomes

Purpose

People undergoing diagnostic genome-scale sequencing are expected to have better psychological outcomes when they can incorporate and act on accurate, relevant knowledge that supports informed decision making.

Methods

This longitudinal study used data from the NCGENES study of diagnostic exome sequencing to evaluate associations between factual genomic knowledge (measured with the University of North Carolina Genomic Knowledge Scale at three assessments from baseline to after return of results) and sequencing outcomes that reflected participants’ perceived understanding of the study and sequencing, regret for joining the study, and responses to learning sequencing results. It also investigated differences in genomic knowledge associated with subgroups differing in race/ethnicity, income, education, health literacy, English proficiency, and prior genetic testing.

Results

Multivariate models revealed higher genomic knowledge at baseline for non-Hispanic Whites and those with higher income, education, and health literacy (ps<.001). These subgroup differences persisted across study assessments despite a general increase in knowledge among all groups. Greater baseline genomic knowledge was associated with lower test-related distress (p=.047) and greater perceived understanding of diagnostic genomic sequencing (ps .04 to <.001).

Conclusion

Findings extend understanding of the role of genomic knowledge in psychological outcomes of diagnostic exome sequencing, providing guidance for additional research and interventions.

Consent for clinical genome sequencing: considerations from the Clinical Sequencing Exploratory Research Consortium

Implementing genome and exome sequencing in clinical practice presents challenges, including obtaining meaningful informed consent. Consent may be challenging due to test limitations such as uncertainties associated with test results and interpretation, complexity created by the potential for additional findings and high patient expectations. We drew on the experiences of research teams within the Clinical Sequencing Exploratory Research (CSER1) Consortium on informed consent for clinical genome and exome sequencing (CGES) to negotiate consensus considerations. We present six considerations for clinicians and 12 key points to communicate as they support patients in deciding whether to undergo CGES. These considerations and key points provide a helpful starting point for informed consent to CGES, grounded in the Clinical Sequencing Exploratory Research (CSER1) experience.

Patient-centered care and genomic medicine: A qualitative provider study in the military health system

The diagnostic and predictive information produced by genomic sequencing may impact medical management, and it is critical that providers and institutions are able to use this information appropriately for patient care. Guided by the patient-centered care model, we investigated provider perspectives of patient, provider, and system-level factors that could influence the implementation of genomic medicine within the integrated healthcare system of the US Department of Defense (DOD). The purpose of this study was to explore patient-centered care elements related to the application of genomic sequencing in a military healthcare facility to understand the current capability and key gaps for patient-centered genomic medicine. Twenty DOD healthcare providers were interviewed regarding their past experiences and future expectations of genetics and genomics. These semi-structured interviews were recorded, transcribed and analyzed. All providers interviewed had some experience with genetics, but the level of experience varied greatly. Providers reported widely differing degrees of knowledge and confidence regarding genetics and about military-specific policies regarding genetics which varied by specialty. In addition, most providers stated that their department did not currently have the infrastructure to allow for the care of patients with secondary genetic findings, defined as genetic findings which are intentionally examined because of their importance to healthcare management, but are unrelated to the reason the individual underwent sequencing. This study reveals gaps in key elements of patient-centered care related to genomic medicine that may be helpful to address in future implementation efforts.

Psychological adaptation to diagnostic genomic sequencing results: The role of hope fulfillment

OBJECTIVE

Psychological adaptation is an important but understudied outcome among patients who undergo DNA evaluation to identify a cause of an unexplained health condition. This longitudinal study examines the relationship between the degree to which participants' hopes for diagnostic genomic sequencing were fulfilled and their psychological adaptation to their sequencing results over time.

METHOD

Secondary analyses were conducted on data from a subset of adult participants from the North Carolina Clinical Genomic Evaluation by Next-Generation Exome Sequencing study with physical health conditions of suspected genetic etiology (such as neurological disorders or cancer; n = 192). Hope fulfillment and type of hope (hopes related to personal-family health implications vs. hoping to help others-advance science) were assessed as predictors of change in psychological adaptation (Psychological Adaptation Scale) and 4 subscales (coping efficacy, self-esteem, social integration, spiritual-existential well-being), from 2 weeks to 6 months after disclosure of genomic sequencing results.

RESULTS

Controlling for covariates, degree of hope fulfillment was associated with increased general psychological adaptation (β = .14, p = .02), social integration (β = .17, p = .01), and spiritual-existential well-being (β = .15, p = .02). Type of hope did not modify effects of degree of hope fulfillment on adaptation outcomes.

CONCLUSIONS

The degree to which patients' genomic sequencing-related hopes are fulfilled may be an important driver of long-term psychological adaptation after genomic sequencing. Evaluating the degree to which patients' hopes are fulfilled may allow clinicians to gain insight into the likely trajectory for patient adaptation after learning their results from genomic sequencing.

Beyond the Helix: Ethical, Legal, and Social Implications in Genomics

OBJECTIVE

To review ethical, legal, and social implications of genomics, a ground-breaking science that when applied improves cancer care outcomes.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health (CINAHL), Cochrane Library, consensus statements, and professional guidelines.

CONCLUSION

Ethical, legal, and social domains of genomics are not fully delineated. Areas needing further discussion and policies include return of findings, informed consent, electronic health records, and data resources and sharing.

IMPLICATIONS FOR NURSING PRACTICE

All nurses need a basic understanding of the ethical, legal, and social implications of genomics.

Rapid Challenges: Ethics and Genomic Neonatal Intensive Care

NICUs are a priority implementation area for genomic medicine. Rapid genomic testing in the NICU is expected to be genomic medicine's "critical application," providing such clear benefits that it drives the adoption of genomics more broadly. Studies from multiple centers worldwide have now demonstrated the clinical utility and cost-effectiveness of rapid genomic sequencing in this setting, paving the way for widespread implementation. However, the introduction of this potentially powerful tool for predicting future impairment in the NICU also raises profound ethical challenges. Developing models of good practice that incorporate the identification, exploration, and analysis of ethical issues will be critical for successful implementation. In this article, we analyze 3 such issues: (1) the value and meaning of gaining consent to a complex test in a stressful, emotionally charged environment; (2) the effect of rapid diagnosis on parent-child bonding and its implications for medical and family decisions, particularly in relation to treatment limitation; and (3) distributive justice (ie, whether the substantial cost and diversion of resources to deliver rapid genomic testing in the NICU can be justified).
