IRB perspectives on obligations to disclose genetic incidental findings to research participants

Abstract

Purpose

Researchers’ obligations to disclose genetic incidental findings (GIFs) have been widely debated, but there has been little empirical study of IRBs’ engagement with this issue.

Methods

This article presents data from the first extensive (n=796) national survey of IRB professionals’ understanding of, experience with, and beliefs surrounding GIFs.

Results

Most respondents had dealt with questions about GIFs (74%), but only a minority (47%) felt prepared to address them. Although a majority believed that there is an obligation to disclose GIFs (78%) there is still not consensus about the supporting ethical principles. Respondents generally did not endorse the idea that researchers’ additional time and effort (7%) and lack of resources (29%) were valid reasons for diminishing a putative obligation. Most (96%) supported a right not to know, but this view became less pronounced (63%) when framed in terms of specific case studies.

Conclusions

IRBs are actively engaged with GIFs, but have not yet reached consensus. Respondents were uncomfortable with arguments that could be used to limit an obligation to return GIFs. This could indicate that IRBs are providing some of the impetus for the trend towards returning GIFs, although questions remain about the relative contribution of other stakeholders.

INTRODUCTION

Genetic sequencing technologies have become an increasingly powerful and affordable research tool,¹ but large-scale whole genome and whole exome studies raise questions about how to manage genetic incidental findings (GIFs).² GIFs are defined here as individual genetic results that are generated in the course of research, but are unrelated to the aims of the research.³ There has been an active debate about the circumstances, if any, under which there is an obligation for researchers to disclose GIFs to research participants.^4,5,6,7 Despite widespread recognition of the importance of this question, decisions about disclosure of GIFs are typically determined at an institutional level, often by institutional review boards (IRBs). There are currently no nationally accepted guidelines to direct researchers’ or IRB professionals’ decisions about disclosure of GIFs discovered during research.⁸

This study represents the first extensive national examination of IRB professionals’ understanding of, experience with, and beliefs surrounding GIFs in the context of genomic sequencing. Prior studies have focused primarily on results generated from genome-wide association studies,⁹ which are less likely to produce GIFs as compared to whole genome and whole exome sequencing,¹⁰ or have employed qualitative methodologies, interviewing limited numbers of subjects.¹¹ Our goal was to capture, quantitatively and on a broader scale, how the research ethics community is currently thinking about the management and disclosure of GIFs in the context of genomic sequencing protocols. Specifically, we explored IRB professionals’ perspectives on whether there is an obligation to return individual genetic results, the ethical principles that the research ethics community appeals to in support of such an obligation, and the reasons that might diminish any potential obligations. We also explored how views on incidental findings vary across demographic characteristics such as professional training, IRB role, and genetic literacy.

MATERIALS AND METHODS

Study Participants and Survey Distribution

We conducted a cross-sectional online survey of individuals sampled from the membership of Public Responsibility in Medicine and Research (PRIM&R), a national nonprofit organization comprised of individual and organizations involved in a variety of kinds of human subjects research. Its membership includes IRB members and other IRB professionals such as administrators and consultants, in addition to researchers and government staff. The survey was piloted using a small cohort of research ethics scholars prior to its wide distribution. A link to a self-administered electronic survey consisting primarily of multiple-choice questions, with some opportunity for short open-ended text answers, was emailed to 2,288 members of PRIM&R who had previously self-identified as having a specific interest in human subjects protections. Participants were provided with a $5 pre-incentive. The response rate was calculated in accordance with RR2 from the American Association for Public Opinion Research¹²; therefore, only partial and complete surveys counted as responses. With 796 completed surveys received, the response rate (RR2) was 34.8%.

Survey Instrument

Participants were introduced to the subject through a brief synopsis about the possibility of GIFs being generated from whole genome and whole exome sequencing. Participants were also provided with definitions of key terms used through the survey. The survey consisted of questions addressing seven central domains: 1) Background and experience with GIFs, 2) Reasons that support an obligation to disclose GIFs, 3) Reasons that diminish an obligation to disclose GIFs, 4) Kinds of GIFs that should be disclosed, 5) Informed consent and procedures for disclosing GIFs, 6) Study design and “loopholes”, and 7) Future of genomic research.

Respondents who expressed a belief that researchers have an obligation to disclose GIFs to research participants were asked about reasons supporting that obligation. All respondents, regardless of how they answered that initial question, were asked about reasons that diminish an obligation to return GIFs. Participants indicated the strength of their agreement with various statements on a five-point Likert scale. Respondents were also given an “other” option with space to write additional reasons. Participants were then presented with hypothetical scenarios involving various types of GIFs and study protocols and were asked to indicate whether there was an obligation to disclose the GIF and whether the various studies should be approved.

Finally, the survey assessed demographic characteristics, background and experience with GIFs, and beliefs about additional guidance. Respondents also completed a 10-item genetic literacy scale adapted from Kaphingst, et al that tested knowledge in two domains (sequencing limitations and sequencing benefits).¹³

Data Analysis

Survey data were exported from Qualtrics, and survey responses were analyzed with descriptive statistics (percentages for discrete responses, means and standard deviations for continuous responses). Summary statistics were calculated using Stata 13. Differences among groups’ responses were calculated by IRB voting status, genetic literacy score, educational level, primary role on the IRB (clinical, scientific, and all others), and combined primary and secondary IRB roles (clinical primary or secondary role; scientific, but not clinical; and not clinical or scientific). Confidence intervals for the proportions were calculated and compared using a two-tailed t-test for differences. Differences with p<0.05 were considered statistically significant. The genomic literacy score was calculated for each domain (limits and benefits). Correct answers where the respondent was confident (“definitely”) scored two points, and less confident correct answers (“probably”) scored one point. The cumulative scores were grouped into low (0-5), moderate (6-9), and high (10) literacy groups.

RESULTS

Respondent Characteristics

The majority of respondents identified as female (74%) and non-Hispanic white (88%). These characteristics are largely consistent with those found in survey research on similar IRB-affiliated populations.¹⁴ The subject pool was generally well-educated, with most respondents (67%) holding a masters or doctoral degree. Most respondents (99%) had been involved with an IRB for at least one year, and 36% had been involved for more than 10 years. Of respondents who identified their current or most recent affiliation role with an IRB, 492 (68%) held a non-voting position, and 235 (32%) served as a voting member of the IRB. Of voting members, 111 (15%) reported filling a chair or vice-chair role. Other voting members reported being scientific members (9%), non-scientific members (5%), community members (2%) and unspecified members (1%). Non-voting affiliates were primarily staff/administrators (60%); the rest (8%) filled other roles such as quality assurance and regulatory compliance.

The majority of our participants (74%) reported having experience dealing with GIFs, suggesting that their survey responses were informed by experience. Respondents expressed moderate confidence in their understanding of ethical issues raised by GIFs (19% very confident, 52% somewhat confident, 35% slightly confident); and slightly lower confidence in their genomic knowledge (9% very confident, 36% somewhat confident, 35% slightly confident). This self-assessment was in line with genetic literacy scores.¹³ When asked about limits of genomic sequencing, only 18% of respondents fell into the high literacy category (56% medium literacy, 26% low literacy). Slightly more than half of the respondents (51%) had high literacy regarding the benefits of genomic sequencing (36% medium literacy, 12% low literacy). Most subjects (73%) had received some training about GIFs, though among those about half (37%) described having only “a little” training. About half (47%) felt at least somewhat well prepared to grapple with GIFs.

A Duty to Disclose GIFs

In general, respondents indicated that researchers have some obligation to disclose GIFs to participants. The majority (65%) indicated that there was “sometimes” an obligation to disclose GIFs; 13% indicated that there was “always” an obligation, and another 13% indicated that there was “rarely” an obligation. Only 2% believed there was never an obligation, and 7% did not know.

Respondents who were grouped into the high genomic literacy cohort (limits scale only) were slightly more likely to be guarded in their agreement of an obligation to disclose GIFs. Although the total percentage of participants who stated that there was always or sometimes an obligation was generally consistent across genomic literacy levels (low=82%, medium=80%, high=72%), the strength of agreement varied by genomic literacy. Participants in the high literacy group were less likely (5%) to answer “yes, always” than those in the low (29%) literacy groups (p>0.05).

Ethical reasoning

Respondents were divided when asked about the ethical principles that might support an obligation to disclose GIFs. The principle with the strongest support was a duty to warn, with 84% of respondents either strongly agreeing or agreeing that researchers should disclose GIFs because of a duty to warn participants if the participants are in significant, imminent danger. Other principles that were widely supported included respect for autonomy of participants (80% of respondents strongly agreed or agreed) and beneficence (79% strongly agreed or agreed). As a cross-check, the participants were asked to rank the top three principles that supported an obligation to disclose GIFs. The top-cited principles remained beneficence, respect for autonomy, and duty to warn. Respondents were more divided in their agreement vs. disagreement on other principles, including professional responsibility (67% vs. 23%), a need to maintain public trust in research (58% vs. 32%), a need to maintain an institution's professional reputation (36% vs. 52%), a need to treat research participants like clinical patients (34% vs. 54%), and reciprocity (34% vs. 56%). Even though professional responsibility and public trust in research garnered more than 50% agreement, close examination of the top three ranking reasons reveals that support for these principles is lower than support for duty to warn, beneficence and autonomy based on the relative percentages of first and second place rankings received (see Figure 1).

Figure 1.

Ethical Principles, top three ranking

A number of participants indicated that they were unsure about certain principles. Most significantly, 18% percent were unsure about whether a concern for legal liability supported an obligation to disclose, and 13% were unsure about whether participants' right to know their own genetic information supported an obligation to disclose. There was some variability related to genomic literacy, with low literacy respondents being significantly more likely (p<0.05) to endorse certain principles (participants should be treated like patients, professional responsibility, and duty to warn) than high literacy respondents.

There were only two potential factors that respondents strongly endorsed as diminishing an obligation to disclose GIFs. Respondents were significantly more likely (p<0.05) to endorse inadequate clinical and analytical validity of the genetic screening information (71%) and inadequate demonstrated clinical utility of the genetic risk information (66%) as valid reasons for reducing an obligation. For the other factors considered, respondents did not believe they negatively affected an obligation to disclose GIFs. Most significantly, only 7% of respondents either agreed or strongly agreed that the additional time and effort required for the researcher to disclose GIFs was great enough to reduce an obligation to do so. Additionally, only 18% of respondents agreed or strongly agreed with the idea that clinical researchers have different responsibilities from those of practicing physicians and thus do not have an obligation to disclose GIFs. Respondents generally also did not accept (23% agreed or strongly agreed) that participants are not likely to understand genetic risk information sufficiently to disclose GIFs, and did not indicate (22% agreed or strongly agreed) that the potential psychological impact on participants of learning their genetic risk information is too high. Finally, only 29% of respondents agreed or strongly agreed that a lack of funding, resources or infrastructure can diminish an obligation to disclose GIFs. There was some variability related to genomic literacy, with high literacy respondents being significantly (p<0.05) more likely than low literacy respondents to identify certain reasons that reduce an obligation to disclose (inadequate scientific validity, inadequate clinical validity, and scientists having different responsibilities as clinicians).

Right not to know

Almost all respondents (96%) indicated that it is either definitely or probably acceptable for a participant to elect not to receive any GIFs. These views shifted when applied to specific case studies, however. Case A involved a participant who had chosen not to receive any GIFs, but whose research team had identified genetic evidence of Hereditary Non-Polyposis Colon Cancer (HNPCC, a serious and actionable disease, also known as Lynch Syndrome). In this case, 26% of respondents replied that the researchers should definitely or probably disclose this finding, 63% replied that researchers should definitely not or probably not disclose this finding, and 11% were unsure. Case B was similar to Case A, but the original participant was deceased, and researchers were debating whether to inform the deceased participant’s family about this potentially significant information. In this case, 51% of respondents believed that researchers should definitely or probably contact the family, 35% thought that researchers should definitely not or probably not contact the family, and 14% were unsure.

DISCUSSION

Questions about whether researchers have a responsibility to disclose genetic incidental findings (GIFs) have been widely debated in the literature. This is the first national (U.S.) survey empirically examining IRB professionals' empirical understanding of GIFs and beliefs about researchers’ obligations to disclose GIFs. Our data demonstrate that a majority of IRB professionals believe that researchers do have a duty to disclose GIFs to research participants. Underlying this perspective is a broad range of opinions about the ethical underpinnings of a duty to disclose GIFs and the various considerations that may or may not limit such a duty.

When the research ethics community began thinking about incidental findings, genomic sequencing technology was in its infancy. The turnaround time from obtaining blood to generating results was long, the cost was prohibitive, and the meaning of much of the information was uncertain. There were real questions about the frequency with which researchers would generate results that would be meaningful to individual participants. Today, with several of these limitations overcome, incidental findings have become more common and the line between research and clinical care has continued to blur. Unsurprisingly, given recent advances in sequencing power, our data suggest that most IRBs today are actively dealing with GIFs; three-quarters of respondents indicated some experience in thinking through these issues. This is no longer a theoretical problem, and we assume that many of our participants’ responses were informed by their actual experiences.

It appears, however, that IRBs are only moderately prepared to face these incidental findings problems. Although 73% of respondents had received some training about GIFs, about half of these (36%) described this training as “a little.” Moreover, while a majority (71%) were very or somewhat confident about their knowledge of the ethical issues GIFs raise, many respondents seemed to desire additional information about genomic science. Only 47% were very or somewhat confident about their genomic knowledge. Overall, respondents reported that they were only moderately prepared to deal with issues raised by GIFs, with fewer than half (47%) indicating that they were very well prepared or somewhat well prepared.

To what extent do IRBs think that there is a duty to disclose GIFs?

Our survey began with a threshold question about whether there is a general duty to offer to disclose incidental findings to participants. Although a majority (78%) of study respondents agreed that there was either sometimes or always an obligation to disclose genetic incidental findings, our data indicate that there is still not complete agreement on this issue. Importantly, a minority of respondents (15%) indicated that there is either rarely or never an obligation to disclose GIFs. This may reflect a general uncertainty or apprehension about the state of genomic science and clinical genomics, a supposition supported by the majority of participants who agreed that a mistrust of scientific accuracy and clinical utility were factors that may reduce an obligation to disclose GIFs. This could also represent a manifestation of the spectrum of approaches to disclosure of GIFs, from research-focused to autonomy-focused, as described by Wilfond and Ravitsky.¹⁵ Whatever the reason for this division, our data reflects a similar split expressed in the literature, providing a good sense for the distribution of IRB support for and against an obligation to offer incidental findings to participants. Although we had hypothesized that views on the existence of an obligation to disclose incidental findings would vary by professional training (e.g., MD vs. PhD) and role (e.g., clinical vs. scientific), there were no statistically significant differences between these groups. There was a modest relationship between genetic literacy (limits scale) and the strength of a perceived duty to disclose; high literacy respondents were less likely to indicate that there is always an obligation to return genetic findings.

What ethical reasons are cited in support of an obligation to disclose GIFs?

Consensus about the scope of researchers’ obligations regarding incidental findings has been elusive. This lack of agreement might be due to the fact that the contours of an obligation will necessarily shift depending on the underlying principle(s) one puts forward.^16,17 In order to learn more about how IRBs are thinking through the incidental findings problem, we asked survey participants about the principles they endorse in support of an obligation to disclose GIFs. While IRB members’ views on certain principles are not dispositive proof of the correct normative view, such data can provide an insight into their ethical reasoning.

Respondents did not endorse a single dominant principle in support of an obligation to disclose GIFs. The three ethical principles that most respondents indicated as supporting an obligation to disclose GIFs were 1) a duty to warn; 2) respect for autonomy; and 3) beneficence (see Table 3). Although these principles can all be used to defend an obligation to disclose GIFs, they can conflict in the breadth of their implied obligation. For example, relying on a duty to warn principle may only require disclosing GIFs that represent significant risk of a serious disease, while beneficence may suggest that all potentially useful or relevant GIFs be disclosed. Similarly, basing this obligation on participant autonomy might suggest returning all GIFs and allowing participants to decide for themselves which ones are most important. Again, we had hypothesized that professional training and role would be correlated with support for different principles, but this did not appear to be the case.

Table 3.

Ethical Principles in Support of an Obligation to Disclose

	Strongly agree or agree
Duty to warn	658 (84%)
Respect for autonomy	626 (80%)
Beneficence	615 (79%)
Professional responsibility	520 (67%)
Public trust in research	450 (58%)
Right to know	418 (54%)
Institutional reputation	278 (36%)
Legal liability	267 (34%)
Participants = patients	264 (34%)
Reciprocity	261 (34%)

Support was quite limited for a number of practical justifications in support of an obligation to disclose, suggesting that our study population found broad philosophical principles more persuasive. Only about a third of respondents agreed with the idea that maintaining an institution's professional reputation and avoiding legal liability supported an obligation to disclose GIFs. Interestingly, a relatively large percentage of respondents (19%) were uncertain about whether a concern for legal liability supported an obligation to disclose GIFs, perhaps due to the lack of existing case law or lack of legal education of respondents. It is possible that views on this rationale for disclosure of GIFs might shift as legal precedent evolves, particularly if the actual risk of liability for non-disclosure increases substantially.

Additionally, 34% of respondents agreed or strongly agreed that an obligation to disclose GIFs rests on a belief that research participants should be treated like clinical patients, with no significant difference between clinicians (40%), scientists (29%) and others (33%), demonstrating that some IRB professionals may see GIFs as existing in a liminal space between research and clinical care, while many others prefer a firm line between the two. Ascertaining this boundary—or lack thereof—is important: while the American College of Genetics and Genomics (ACMG) has released guidelines for disclosing certain GIFs in the context of clinical genomics,¹⁸ there have been no equivalent guidelines suggested for the research realm as of yet. Instead, many institutions rely on a local advisory board in collaboration with IRBs who ultimately accept or reject a request to disclose genetic findings. If, as our survey suggests, some IRB professionals believe that research participants should be treated like clinical patients, this may lend credence to concerns about the appropriateness of applying the ACMG guidelines to the research realm.¹⁹

The other principle that respondents disagreed with most strongly (56% either disagreed or strongly disagreed) was reciprocity between researchers and participants, or the idea that researchers should disclose GIFs because they owe participants something in exchange for their contribution to the research endeavor. This support for the principle of reciprocity was surprisingly low, given that it is often cited in the literature in support of an obligation to disclose GIFs,²⁰ suggesting that these arguments have less traction in the way that IRBs think about the incidental findings problem. A significant portion of respondents were also unsure about whether an obligation to disclose GIFs is supported by an inherent right of research participants to know their own genetic information, possibly indicating survey respondents’ uncertainty about the existence of such a right.

Limitations of an obligation to disclose GIFs

When asked about the factors or circumstances that could potentially reduce an obligation to disclose GIFs, respondents largely found many of the suggested factors unconvincing. In particular, respondents surprisingly rejected excuses such as a lack of resources to disclose GIFs or the burden of additional time and effort required to do so, both of which are identified within the literature as significant obstacles to declaring a broad obligation to disclose.^21,22 Respondents agreed only that inadequate clinical or scientific information reduces an obligation to disclose GIFs. Since both of these factors are based on the current state of science and clinical medicine, it is possible that as the evidence base develops, opinions on whether GIFs should be disclosed may also change.

Survey respondents also rejected arguments based on paternalistic concern for research participants, reaffirming the data indicating that an obligation to disclose GIFs rests at least partly on respect for participant autonomy. Over two thirds of respondents (70%) disagreed that an obligation to disclose GIFs is reduced by a worry that participants are not likely to understand genetic risk information, and 67% of respondents disagreed that the potential psychological impact on participants of learning their genetic risk information is too significant to disclose GIFs.

Interestingly, 73% of participants either disagreed or strongly disagreed with the idea that the unique role of the clinical investigator, and particularly the lack of clinical responsibilities equivalent to those of practicing physicians, excuses researchers from disclosing GIFs. This suggests that respondents believe clinical researchers should behave similarly to physicians. Most respondents, however, also rejected the idea that research participants should be treated like clinical patients. This inconsistency in beliefs about the difference between research and clinical care underlines again how incidental findings are calling into question the distinction between these two spheres, thereby further complicating efforts to evaluate GIF disclosure policies within clinical research protocols.

Right Not to Know

The question of whether research participants have a “right not to know” certain genetic information about themselves continues to be a controversial issue, particularly after the release of the ACMG recommendations.^23,24,25 It is clear from our data that while respondents may have strong beliefs about this right in theory, in practice their views are more complicated. Almost all respondents indicated that it is definitely or probably acceptable for a participant to elect not to receive any GIFs, but this strong consensus wavered in the face of a specific case. When considering Case A, in which a research team found a highly significant and actionable GIF in the genomic data of a research participant who had elected not to receive any GIFs, a full quarter of respondents said that the research team should either definitely or probably disclose the GIF anyway. In Case B, where the original research participant was deceased but had similarly elected not to receive any GIFs, half of respondents thought the research team should either definitely or probably contact the participant's family.

The data supporting these case studies are consistent with the strong consensus that an obligation to disclose GIFs rests on a duty to warn participants who are in significant, imminent danger. It is important, then, for the research ethics community to come to a clear consensus about whether there is truly a strict right for participants not to know any genetic information about themselves, and for this position to be communicated and enforced throughout the informed consent process. Holding an inconsistent position in this area could potentially compromise participant trust in research, as well-meaning researchers disclose information to participants who had previously elected not to receive it. Additionally, in order to ensure that research participants truly understand the meaning and implications of not receiving GIFs, it might be necessary to change the process of consent and have a second discussion about the significance of findings once results are obtained without disclosing the actual results.

Study Limitations

Our study has several important limitations. First, our response rate was moderate and nonresponse bias may affect the generalizability of the results. Second, it is possible that subjects were influenced by social acceptability bias. There has been significant discussion about incidental findings, and the field has been moving towards a view that there is an obligation to disclose some set of findings, which could have influenced what respondents thought was the desirable answer. Third, our sample was primarily comprised of non-voting IRB professionals and was also disproportionately female. While it is possible that non-voting IRB professionals could hold different views from voting IRB members, or men from women, we found no statistically significant differences between these groups given our sample size. Furthermore, we believe our study population is appropriately representative of the human subjects research ethics community since it was drawn from PRIM&R, the preeminent organization for the research ethics profession. Fourth, we found few differences by professional training or role, although this could have been due to the small size of some of these subgroups. Given these limitations, additional research would be helpful to more confidently assess the views of IRB members, particularly to see how they change over time in this rapidly evolving field.

CONCLUSION

The debate about whether or not to disclose genetic incidental findings has been vigorous and continues to evolve, but it has lacked empirical data about the deliberative processes being used to oversee management in the research setting. This study is the first exploration of how IRBs are actually grappling with the ethical issues presented by the massive amount of data generated by genomic research. Our research indicates that IRBs are actively engaged with this problem, but like the rest of the field, have not yet reached clear consensus. The majority of respondents, however, think that return of GIFs is appropriate, and have apparent discomfort with arguments that might constrain a duty to return GIFs. This could indicate that IRBs are providing at least some significant portion of the impetus for the trend towards returning incidental findings, although interesting questions remain about the relative contribution of other stakeholders, such as academic bioethicists, researchers, research participants, or funding agencies.
