Single IRB Review and Local Context Considerations: A Scoping Review.

A leading concern about single IRB (sIRB) review for multisite studies, as is now required by federal policies, is whether and how sIRBs consider local context in their review. While several types of local context considerations have been proposed, there is no shared agreement among those charged with the ethics oversight of human subjects research as to the goals and content of local context review, nor the types of research studies for which sIRB review might be inappropriate. Through a scoping review of published scholarship, public comments, and federal guidance documents, we identified five assumed goals for local context review: protecting the rights and welfare of local participants; ensuring compliance with applicable laws and policies; assessing feasibility; promoting the quality of research; and promoting procedural justice. While a variety of content was proposed to be relevant, it was largely grouped into four domains: population/participant-level characteristics; investigator and research team characteristics; institution-level characteristics; and state and local laws. Proposed characteristics for exclusion from sIRB requirements reflected both protection- and efficiency-based concerns. These findings can inform ongoing efforts to assess the implications of policies mandating sIRB review, and when exceptions to those policies might be appropriate.

Prioritization of ethical concerns regarding HIV molecular epidemiology by public health practitioners and researchers.

BACKGROUND: HIV molecular epidemiology (HIV ME) can support the early detection of emerging clusters of new HIV infections by combining HIV sequence data routinely obtained during the clinical treatment of people living with HIV with behavioral, geographic, and sociodemographic information. While information about emerging clusters promises to facilitate HIV prevention and treatment efforts, the use of this data also raises several ethical concerns. We sought to assess how those working on the frontlines of HIV ME, specifically public health practitioners (PHPs) and researchers, prioritized these issues. METHODS: Ethical issues were identified through literature review, qualitative in-depth interviews, and stakeholder engagement. PHPs and researchers using HIV ME prioritized the issues using best-worst scaling (BWS). A balanced incomplete block design was used to generate 11 choice tasks each consisting of a sub-set of 5 ethical concerns. In each task, respondents were asked to assess the most and least concerning issue. Data were analyzed using conditional logit, with a Swait-Louviere test of poolability. Latent class analysis was then used to explore preference heterogeneity. RESULTS: In total, 57 respondents completed the BWS experiment May-June 2023 with the Swait-Louviere test indicating that researchers and PHPs could be pooled (p = 0.512). Latent class analysis identified two classes, those highlighting "Harms" (n = 29) (prioritizing concerns about potential risk of legal prosecution, individual harm, and group stigma) and those highlighting "Utility" (n = 28) (prioritizing concerns about limited evidence, resource allocation, non-disclosure of data use for HIV ME, and the potential to infer the directionality of HIV transmission). There were no differences in the characteristics of members across classes. CONCLUSIONS: The ethical issues of HIV ME vary in importance among stakeholders, reflecting different perspectives on the potential impact and usefulness of the data. Knowing these differences exist can directly inform the focus of future deliberations about the policies and practices of HIV ME in the United States.

Stakeholder perspectives on data sharing from pragmatic clinical trials: Unanticipated challenges for meeting emerging requirements.

Introduction: Numerous arguments have been advanced for broadly sharing de-identified, participant-level clinical trial data. However, data sharing in pragmatic clinical trials (PCTs) presents ethical challenges. While prior scholarship has described aspects of PCTs that raise distinct considerations for data sharing, there have been no reports of the experiences of those at the leading edge of data-sharing efforts for PCTs, including how these particular challenges have been navigated. To address this gap, we conducted interviews with key stakeholders, with a focus on the ethical issues presented by sharing data from PCTs. Methods: We recruited respondents using purposive sampling to reflect the range of stakeholder groups affected by efforts to expand PCT data sharing. Through semi-structured interviews, we explored respondents' experiences and perceptions about sharing de-identified, individual-level data from PCTs. An integrated approach was used to identify and describe key themes. Results: We conducted 40 interviews between April and September 2022. Five overarching themes emerged through analysis: (1) challenges in sharing data collected under a waiver or alteration of consent; (2) conflicting views regarding PCT patient-subject preferences for data sharing; (3) identification of respect-promoting practices beyond consent; (4) concerns about elevated risks or burdens from sharing PCT data; and (5) diverse views about the likely benefits resulting from sharing PCT data. Conclusion: Our data indicate unresolved tensions in how to fulfill the expectation to broadly share de-identified, individual-level data from PCTs, and suggest that those promulgating and implementing data-sharing policies must be sensitive to PCT-specific considerations. Future work could inform efforts to tailor data-sharing policy and practice to reflect the challenges presented by PCTs, including sharing experiences from trials that have successfully navigated these tensions.

The ethics of using COVID-19 host genomic information for clinical and public health decision-making: A survey of US health professionals.

Several genetic variants linked to COVID-19 have been identified by host genomics researchers. Further advances in this research will likely play a role in the clinical management and public health control of future infectious disease outbreaks. The implementation of genetic testing to identify host genomic risk factors associated with infectious diseases raises several ethical, legal, and social implications (ELSIs). As an important stakeholder group, health professionals can provide key insights into these ELSI issues. In 2021, a cross-sectional online survey was fielded to US health professionals. The survey explored how they view the value and ethical acceptability of using COVID-19 host genomic information in three main decision-making settings: (1) clinical, (2) public health, and (3) workforce. The survey also assessed participants' personal and professional experience with genomics and infectious diseases and collected key demographic data. A total of 603 participants completed the survey. A majority (84%) of participants agreed that it is ethically acceptable to use host genomics to make decisions about clinical care and 73% agreed that genetic screening has an important role to play in the public health control of COVID-19. However, more than 90% disagreed that it is ethically acceptable to use host genomics to deny resources or admission to individuals when hospital resources are scarce. Understanding stakeholder perspectives and anticipating ELSI issues will help inform policies for hospitals and public health departments to evaluate and perhaps adopt host genomic technologies in an ethically and socially responsible manner during future infectious disease outbreaks.

Policy options to facilitate cancer genomic variant data sharing: outcomes of a modified policy Delphi.

Sharing cancer gene variant and relevant clinical data could accelerate progress in cancer genomics. However, data sharing is currently impeded by issues related to financial sustainability, equity, incentives, privacy and security, and data quality. Evidence-based policy options to facilitate data sharing in these domains, and ultimately improve interpretation of cancer-associated genomic variants, are therefore needed. We conducted a modified policy Delphi with expert stakeholders that involved generating, evaluating, and ranking potential policy options to address these issues, with a focus on the US context. We found policy options in the financial sustainability domain were highly ranked, particularly stable funding for trusted entities. However, some Delphi panelists noted that the culture of public research funding has favored short-term grants. Panelists favored policy options focused on action by funders, which had the highest overall total scores that combined effectiveness and feasibility ratings and priority ranking within domains. Panelists also endorsed some policy options connected to actors such as journals, but they were more skeptical of policy options connected to legislative actors and data resources. These findings are critical inputs for policy makers as they consider policies to enable sharing of cancer gene variant data to improve health.

Fresh takes on five health data sharing domains: Quality, privacy, equity, incentives, and sustainability.

As entities around the world invest in repositories and other infrastructure to facilitate health data sharing, scalable solutions to data sharing challenges are needed. We conducted semi-structured interviews with 24 experts to explore views on potential issues and policy options related to health data sharing. In this Perspective, we describe and contextualize unconventional insights shared by our interviewees relevant to issues in five domains: data quality, privacy, equity, incentives, and sustainability. These insights question a focus on granular quality metrics for gatekeeping; challenge enthusiasm for maximalist risk disclosure practices; call attention to power dynamics that potentially compromise the patient's voice; encourage faith in the sharing proclivities of new generations of scientists; and endorse accounting for personal disposition in the selection of long-term partners. We consider the merits of each insight with the broad goal of encouraging creative thinking to address data sharing challenges.

Brief Report: Challenges in Obtaining the Informed Perspectives of Stakeholders Regarding HIV Molecular Epidemiology.

BACKGROUND: HIV molecular epidemiology (HIV-ME) is now being used in a variety of ways, including molecular HIV surveillance to help identify and respond to emerging HIV transmission clusters as specified in the Ending the HIV Epidemic in the U.S. initiative. However, HIV-ME in general, and its use for cluster detection and response, in particular, raises significant ethical and social concerns, which have spurred vigorous debates. Nevertheless, there is a paucity of information regarding how these potential benefits and concerns are perceived among people living with HIV and people without HIV at an increased risk. SETTING: Virtual engagement with US participants. METHODS: We rigorously developed a brief informational video about HIV-ME and conducted a series of in-depth interviews with people living with HIV and people without HIV at an increased risk. RESULTS: Through extensive stakeholder engagement during the video development process and subsequent in-depth interviews (N = 24), several preliminary findings surfaced. In contrast to the high level of concern raised by some critics of HIV-ME, our data appear to show broad support for it. In addition, we observed conflation of perspectives about HIV-ME with concerns about HIV public health surveillance more generally. CONCLUSION: Our experiences reveal substantial communication challenges related to the nature of HIV-ME that need to be overcome to ensure that it is properly understood, which is necessary for meaningfully engaging stakeholders in discussions about its use. Moreover, ongoing, responsive, engagement efforts are critical. Additional systematic data are needed to help inform policy making and practice regarding HIV-ME.

Ethics challenges in sharing data from pragmatic clinical trials.

Numerous arguments have been advanced for broadly sharing de-identified, participant-level clinical trials data, and trial sponsors and journals are increasingly requiring it. However, data sharing in pragmatic clinical trials presents ethical challenges related to the use of waivers or alterations of informed consent for some pragmatic clinical trials and corresponding limitations of informed consent to guide sharing decisions; the potential for data sharing in pragmatic clinical trials to present risks not only for individual patient-subjects, but also for health systems and the clinicians within them; sharing of data from electronic health records instead of data newly collected for research purposes; and researchers' limited capacity to control sensitive data within an electronic health record and potential implications of such limits for meeting obligations inherent to Certificates of Confidentiality. These challenges raise questions about the extent to which traditional research ethics governance structures are capable of guiding decisions about pragmatic clinical trial data sharing. This article identifies and examines these ethical challenges for pragmatic clinical trial data sharing. We suggest several areas for future empirical scholarship, including the need to identify patient and public attitudes regarding pragmatic clinical trial data sharing as well as to assess the demand for pragmatic clinical trial data and the correspondingly likely benefit of such sharing. Further conceptual work is also needed to explore how requirements to respect patient-subjects about whom data are shared in the context of pragmatic clinical trials should be understood, particularly in the absence of informed consent for initial research activities, and the appropriate balance between promoting the generation of socially valuable knowledge and respecting autonomy.

Identifying Needs, Challenges, and Benefits Among Adults and Parents of Children With Hirschsprung Disease.

ABSTRACT: Adults with Hirschsprung disease (HD), unaffected parents of children with HD, and affected adults with an affected child completed a cross-sectional survey with open-ended questions about greatest needs at diagnosis and at current time, greatest challenges encountered, and any benefits of having HD or having a child with HD. In the 297 respondents, information and good medical care were common needs at diagnosis and at the time of survey, but the information needed evolved with time. Managing ongoing symptoms was a frequently cited need and challenge, along with managing medical care and the social and emotional impact of HD. Perceived benefits included empathy for others and new perspectives on life. The needs and challenges identified in this study can guide healthcare providers in discussions with families. Provision of information, recommendations, and referrals based on each individual family's needs can support families with HD throughout the lifecycle and facilitate adaptation.

Patients' Reactions to Letters Communicating Collateral Findings of Pragmatic Clinical Trials: a National Web-Based Survey.

BACKGROUND: Collateral findings in pragmatic clinical trials are findings that may have implications for patients' health but were not generated to address a trial's primary research questions. It is uncertain how best to communicate these collateral findings to patients. OBJECTIVES: To determine how reactions to a letter communicating collateral findings relate to who signed the letter, the type of finding, or whether the letter specified that the finding arose from a pragmatic clinical trial. RESEARCH DESIGN: Web-based survey experiment using a between-subjects design in which respondents were randomly assigned within education strata to view and respond to 1 of 16 hypothetical scenarios. SUBJECTS: Adults recruited from an online panel constructed from a probability sample of US-based postal addresses. MEASURES: The primary outcomes were the action the respondent would take next (i.e., contact a doctor immediately or something else) and the respondent's emotional reactions (i.e., all positive, all negative, mixed, or none). RESULTS: A total of 4080 respondents had analyzable data. Although some effects were statistically significant (P < .05), none exceeded a prespecified threshold for policy relevance (15 or more percentage points). Ratings of letter clarity and level of understanding were lower for letters that included a description of the clinical trial. CONCLUSIONS: Signatory and level of detail about collateral findings did not substantially affect people's intentions to take the recommended action of contacting their doctor. Deciding whether to include a description of the pragmatic clinical trial requires a trade-off between transparency and more difficulty understanding the contents of the letter.

Stakeholder perspectives regarding pragmatic clinical trial collateral findings.

CONTEXT: Pragmatic clinical trials (PCTs), which are becoming widespread since they are relatively inexpensive and offer important benefits for healthcare decision-making, can also present practical, ethical, and legal challenges. One such challenge involves managing "pragmatic clinical trial collateral findings" (PCT-CFs), or information emerging in a PCT that is unrelated to the primary research question(s), yet may have implications for individual patients, clinicians, or health care systems from whom or within which data were collected. The expansion of PCTs makes it likely healthcare systems will increasingly encounter PCT-CFs, yet little guidance exists regarding their appropriate management. METHODS: We conducted semi-structured interviews with key stakeholders experienced in the conduct or oversight of PCTs and those in health system leadership. Interviews explored respondents' experience with PCTs and PCT-CFs, and actual or hypothetical reactions to PCT-CF management. We used standard methods of qualitative analysis to identify key themes. FINDINGS: Forty-one stakeholders participated. Four key themes emerged. First, discussions of PCT-CFs are complicated by layers of ambiguity related to both the nature of PCTs themselves, and unanticipated results that emanate from them. Second, management of PCT-CFs is context-specific, and not amenable to a "one-size-fits-all" approach. Third, there was a wide diversity of attitudes regarding the scope of researcher responsibilities in PCTs. Fourth, PCT-CFs had generally not been previously considered by respondents, but there was widespread belief in the importance of prospective planning to anticipate such issues in future PCTs. CONCLUSIONS: PCT-CFs are likely to increase, yet those charged with PCT-CF decision-making and their disclosure are unlikely to have experience with these issues. Further deliberation about the ethical obligations and implementation processes regarding PCT-CFs is needed. To enhance the likelihood of developing sound policies and practices, such deliberations should include the input and perspectives of key stakeholders in PCTs, including professionals, policy makers, and patients.

Identification and management of pragmatic clinical trial collateral findings: A current understanding and directions for future research.

While the embedded nature of pragmatic clinical trials (PCTs) can improve the efficiency and relevance of research for multiple stakeholders, embedding research into ongoing clinical care can also involve ethical and regulatory challenges. An emergent challenge is the management of pragmatic clinical trial collateral findings (PCT-CFs). While PCT-CFs share some features with incidental or secondary findings that are encountered in conventional clinical trials and clinical care, the PCT context differs in ethically relevant ways that complicate PCT-CF identification and management. We report on the results of a two-year multi-method investigation of PCT-CFs. Overall, five core themes emerged: 1) the liminal nature of PCTs and the implications of this for PCT-CFs; 2) the context-specific nature of PCT-CF management; 3) the centrality of institutions; 4) the importance of prospective planning; and 5) patient expectations. Among the central lessons of this work are that prior ethics guidance from other settings cannot easily be adapted to address PCT-CFs, nor can a single approach readily accommodate all PCT-CFs. Moving forward, stakeholders, including researchers, institutions, ethics oversight bodies, and funders, should anticipate and plan for PCT-CFs in the design, conduct, and analysis of PCTs. Future scholarship is needed to examine experiences with PCT-CFs, and the practical and conceptual issues they raise for the future conduct of PCTs.

Challenges to Building a Gene Variant Commons to Assess Hereditary Cancer Risk: Results of a Modified Policy Delphi Panel Deliberation.

Understanding the clinical significance of variants associated with hereditary cancer risk requires access to a pooled data resource or network of resources-a "cancer gene variant commons"-incorporating representative, well-characterized genetic data, metadata, and, for some purposes, pathways to case-level data. Several initiatives have invested significant resources into collecting and sharing cancer gene variant data, but further progress hinges on identifying and addressing unresolved policy issues. This commentary provides insights from a modified policy Delphi process involving experts from a range of stakeholder groups involved in the data-sharing ecosystem. In particular, we describe policy issues and options generated by Delphi participants in five domains critical to the development of an effective cancer gene variant commons: incentives, financial sustainability, privacy and security, equity, and data quality. Our intention is to stimulate wider discussion and lay a foundation for further work evaluating policy options more in-depth and mapping them to those who have the power to bring about change. Addressing issues in these five domains will contribute to a cancer gene variant commons that supports better care for at-risk and affected patients, empowers patient communities, and advances research on hereditary cancers.

Patients' perspectives on the derivation and use of organoids.

Organoid research is enhancing understanding of human development and diseases as well as aiding in medication development and selection, raising hopes for even more future therapeutic options. Nevertheless, this work raises important ethical issues and there is a paucity of data regarding patients' perspectives on them. We report on 60 interviews with adult patients or parents of pediatric patients from diverse disease populations who receive medical care at a major academic research institution in the United States. Interviewees expressed broad support for organoid development and use. However, patients viewed brain organoids, and sometimes gonadal organoids, as morally distinct; and some organoid research poses moral concerns. Nonetheless, patients generally understood the potential value of such research and approved of it, provided it was aimed at good intent and conducted with ethical oversight and a robust consent process. These data should help inform conceptual and policy deliberations about appropriate organoid use.

Multiple, independent, common variants at RET, SEMA3 and NRG1 gut enhancers specify Hirschsprung disease risk in European ancestry subjects.

PURPOSE: Hirschsprung disease (HSCR) is a developmental disorder of the enteric nervous system (ENS) characterized by congenital aganglionosis arising from coding variants in ENS genes causing partial or total loss-of-function. Low-penetrance, common, noncoding variants at RET, SEMA3 and NRG1 loci are also associated with HSCR, with small-to-moderate loss of gene expression mediated through sequence variants in cis-regulatory elements (CRE) as another causal mechanism. Since these latter variants are common, many individuals carry multiple risk variants. However, the extent and combinatorial effects of all putative CRE variants within and across these loci on HSCR is unknown. METHODS: Using 583 HSCR subjects, one of the largest samples of European ancestry studied, and genotyping 56 tag variants, we evaluated association of all common variants overlapping putative gut CREs and fine-mapped causal variants at RET, SEMA3 and NRG1. RESULTS: We demonstrate that 28 and 8 tag variants, several of which are genetically independent, overlap putative-enhancers at the RET and SEMA3 loci, respectively, as well as two fine-mapped tag variants at the NRG1 locus, are significantly associated with HSCR. Importantly, disease risk increases with increasing numbers of risk alleles from multiple variants within and across these loci, varying >25-fold across individuals. CONCLUSION: This increasing allele number-dependent risk, we hypothesize, arises from HSCR-relevant ENS cells sensing the reduced gene expression at multiple ENS genes since their developmental effects are integrated through gene regulatory networks.

A scoping review of genetics and genomics research ethics policies and guidelines for Africa.

BACKGROUND: Genetics and genomics research (GGR) is increasingly being conducted around the world; yet, researchers and research oversight entities in many countries have struggled with ethical challenges. A range of ethics and regulatory issues need to be addressed through comprehensive policy frameworks that integrate with local environments. While important efforts have been made to enhance understanding and awareness of ethical dimensions of GGR in Africa, including through the H3Africa initiative, there remains a need for in-depth policy review, at a country-level, to inform and stimulate local policy development and revision on the continent. METHODS: To identify and characterize existing ethics-related guidelines and laws applicable to GGR across much of Africa, we conducted a scoping review of English language policy documents identified through databases, repositories, and web searches. Thirty-six documents were included and coded using a framework that contained a range of themes across five analytical categories: (1) respect, (2) beneficence, (3) justice, (4) independent oversight, and (5) bans and prohibitions. Data analysis software (NVivo 12) was used to organize, code, and tabulate information according to document characteristics and topics. Illustrative examples of policy requirements were selected for inclusion. RESULTS: Documents that met inclusion criteria spanned 20 years; published between 1996 and 2018, with the majority (58%) published after 2009. About two-thirds were denoted as "guidelines," and slightly more than half were non-exclusive to GGR. Very few (six) country-level documents identified were specific to GGR. Requirements related to the principle of "respect" appeared most often across all documents, relative to other principles and processes. The most commonly stated ban was on reproductive cloning. Other prohibitions applied to germline editing, undue inducements in research, sample use for commercial purposes, employee mandatory DNA testing, fetal sex selection, stem cell use, eugenics, and research without public health benefits. CONCLUSIONS: Enforceable policies that are indispensable to the ethical conduct and review of GGR are either deficient or missing in many African countries. Existing international, GGR-specific ethics guidelines can be used to inform GGR policy development at a country-level, in conjunction with insight from country specific ethics committees and other local stakeholders.

Whether, when, and how to communicate genetic risk to minors: 'I wanted more information but I think they were scared I couldn't handle it'.

Genetic test results are often relevant not only to persons tested, but also to their children. Questions of whether, when, and how to disclose parental test results to children, particularly minors, can be difficult for parents to navigate. Currently, limited data are available on these questions from the perspective of minors. In this qualitative study, semi-structured interviews were conducted with parents affected by or at risk for hereditary cancer (N = 17) or Huntington's disease (N = 14) and their mature minor children aged 15-17 (N = 34). Parents and mature minors were interviewed separately. Genetic counselors (GCs; N = 19) were also interviewed. Most parents interviewed wanted to protect minors from genetic risk information (GRI) and feared minors would not be able to handle GRI. However, most mature minors reported they did not receive enough information and wished their parent was more forthcoming. Parents recommended taking time to process one's own test results before communicating with minors, and mature minors recommended parents communicate GRI in an honest, hopeful way. Most parents and GCs felt additional resources on communicating with minors about GRI and various genetic conditions are needed. This study includes the experiences and perspectives of a well-informed cohort, and results should be taken into careful consideration by parents, GCs, and others who are faced with communicating GRI to minors.

Patients' Views About the Disclosure of Collateral Findings in Pragmatic Clinical Trials: a Focus Group Study.

BACKGROUND: Pragmatic clinical trials (PCTs) are increasingly being conducted to efficiently generate evidence to inform healthcare decision-making. Despite their growing acceptance, PCTs may involve a variety of ethical issues, including the management of pragmatic clinical trial-collateral findings (PCT-CFs), that is, information that emerges in PCTs that is unrelated to the primary research questions but may have implications for patients, clinicians, and health systems. OBJECTIVE: We sought to understand patients' views about PCT-CF disclosure, including how, by whom, and the nature and extent of information provided. DESIGN: Prospective, qualitative focus group study. PARTICIPANTS: Focus groups were conducted in Baltimore, MD; Houston, TX; and Seattle, WA (overall N = 66), during July and August 2019. APPROACH: All groups discussed a hypothetical scenario involving the detection of a PCT-CF of contraindicated medications. Participants were asked about their reactions to the PCT-CF and issues related to its disclosure. KEY RESULTS: Reactions to learning about the PCT-CF were mixed, ranging from fear of a significant health problem, anger that the contraindicated medications had gone unnoticed and/or for being included in research without their permission, to gratitude for the information. Preferences for how such disclosures are made varied but were driven by several consistent desires, namely minimizing patient harm and anxiety and demonstrating trust and respect. Many wanted their treating clinician to be informed of the PCT-CF so that they would be prepared to answer patients' questions and to discuss treatment options. CONCLUSIONS: The detection of PCT-CFs is likely to increase with further expansion of PCTs. As such, clinicians will undoubtedly become involved in the management of PCT-CFs. Our data illustrate some of the challenges clinicians may face when their patients are informed of a PCT-CF and the need to develop guidance for disclosing PCT-CFs in ways that align with patients' preferences and values.

Family Communication Patterns and Challenges of Huntington's Disease Risk, the Decision to Pursue Presymptomatic Testing, and Test Results.

BACKGROUND: Communicating genetic information within families can provide individuals with the emotional support, alert family members to their own potential risk, and strengthen relationships. However, these communications have the potential to cause emotional distress to individuals and family members if family members are informed of a risk they do not wish to know or discuss. Communication about the decision to pursue testing and test results are especially sensitive in Huntington's disease (HD), where individuals often feel strongly about either knowing or not knowing their genetic status. OBJECTIVE: To examine family communication patterns of genetic risk, the decision to pursue testing, and test results not just years, but decades after testing for HD, and examine how family communication of genetic risk information affects family relationships over the long-term. METHODS: In this qualitative study, 39 semi-structured interviews were conducted with probands who went through genetic testing for HD. Clinic notes from these individuals were also analyzed. RESULTS: Family communication patterns varied based on relation (e.g., significant others, child, extended family) and were influenced by a variety of factors. Sharing with spouses and children had a positive influence on the relationship in most cases. Sharing with extended family members had varying effects on relationships. Negative effects were more likely when family members were in denial, had not pursued testing for themselves, or did not support testing. CONCLUSION: Communication to significant others and children, should be discussed with and supported in individuals seeking testing for HD, but for extended family members, potential effects on the relationship, emotional distress, and benefits should be discussed and weighed.

Ethics and Collateral Findings in Pragmatic Clinical Trials.

Pragmatic clinical trials (PCTs) offer important benefits, such as generating evidence that is suited to inform real-world health care decisions and increasing research efficiency. However, PCTs also present ethical challenges. One such challenge involves the management of information that emerges in a PCT that is unrelated to the primary research question(s), yet may have implications for the individual patients, clinicians, or health care systems from whom or within which research data were collected. We term these findings as ?pragmatic clinical trial collateral findings,? or ?PCT-CFs?. In this article, we explore the ethical considerations associated with the identification, assessment, and management of PCT-CFs, and how these considerations may vary based upon the attributes of a specific PCT. Our purpose is to map the terrain of PCT-CFs to serve as a foundation for future scholarship as well as policy-making and to facilitate careful deliberation about actual cases as they occur in practice.
