Return of Individual Research Results: A Guide for Biomedical Researchers Utilizing Human Biospecimens

GBA/GBN-position on the feedback of incidental findings in biobank-based research: consensus-based workflow for hospital-based biobanks

Incidental research findings pose a considerable challenge to hospital-based research biobanks since they are acting as intermediaries between healthcare and research. In a joint action the centralized biobank ibdw (Interdisciplinary Bank of Biomaterials and Data Wuerzburg) together with local authorities drafted a coherent concept to manage incidental research findings in full compliance with relevant ethical and data privacy regulations. The concept was developed and elaborated in close collaboration with the German Biobank Alliance (GBA). Comprehensive documentation of all steps guarantees the traceability of the process. By a mandatory assessment of the findings prior to re-identification of the individual concerned, unnecessary measures can be avoided. The individual's "right not to know" is respected according to the stipulations of the informed consent. As a general principle any communication with the individual occurs exclusively through the hospital and by competent physicians with appropriate knowledge and communication skills. We propose this scheme as a blueprint for reporting workflows for incidental research findings at hospital-based biobanks.

Return of Individual Research Results: Participant Perspectives in a Longitudinal Community-Based Sample

The last decade has witnessed growing calls for the return of individual research results. Prior work in genetic studies has shown that individual, contextual, and cultural factors influence participants' preferences for individual research results. There is a gap in knowledge about participants' views about other types of results, specifically those lacking clinical significance. This study investigates the perspectives of 1587 mothers enrolled in the Northern Plains Environmental Influences on Child Health Outcomes (ECHO) Program. Participants were presented with hypothetical scenarios to determine their perceived value of individual research results based on result type and the ability to interpret them within a normative context. Irrespective of the result type, participants attributed higher perceived value to results that were well understood than results of unknown significance.

How do Hispanics/Latinos Perceive and Value the Return of Research Results?

Introduction: Interest in the return of research results has been increasing; however, little is known about how Hispanics/Latinos perceive and value receiving results. This study examined differences among Hispanics/Latinos by education and income in the experience and expectations about the return of research results, perceived value of specific types of information, and the least and most valuable specific information. Method: Retrospective observational design using a cross-sectional national survey sample of Hispanics/Latinos (n = 327). Results: Higher educational attainment was positively associated with the expectation to receive research results, likelihood to participate in research if given study findings, and likelihood to trust researchers if given results. Higher income was positively associated with the perceived value of getting results. Respondents with higher education specifically perceived greater value in information about how lifestyle and genetics affect their risk of disease, how genetics affect how they respond to medications, their ancestry, available clinical trials near them, and how to connect with other study participants. Respondents with higher income perceived greater value in information about how genetics affect their risk of disease and how they respond to medications. Conclusion: The findings offer important insights for planning research initiatives and for developing culturally targeted educational materials for Hispanics/Latinos.

Returning Individual Research Results to Vulnerable Individuals

Although issues associated with returning individual research results to study participants have been well explored, these issues have been less thoroughly investigated in vulnerable individuals and populations. Considerations regarding return of research results to these individuals and populations, including how best to ensure truly informed consent, how to minimize the risks and benefits of the return of research results, and how best to ensure justice may differ from those of the population at large. This article discusses the issues and challenges associated with the return of individual research results (such as genomic, proteomic, or other biomarker data) to potentially vulnerable individuals and populations, including those who may be vulnerable for cognitive, communicative, institutional, social, deferential, medical, economic, or social reasons. It explores factors that should be considered in the design, conduct, and oversight of ethically responsible research involving the return of research results to vulnerable individuals and populations and discuss recommendations for those engaged in this work.

The burden of pathogenic variants in clinically actionable genes in a founder population

Founder populations may be enriched with certain genetic variants of high clinical impact compared to nonfounder populations due to bottleneck events and genetic drift. Using exome sequencing (ES), we quantified the load of pathogenic variants that may be clinically actionable in 6136 apparently healthy adults living in the Lancaster, PA Old Order Amish settlement. We focused on variants in 78 genes deemed clinically actionable by the American College of Medical Genetics and Genomics (ACMG) or Geisinger's MyCode Health Initiative. ES revealed 3191 total variants among these genes including 480 nonsynonymous variants. After quality control and filtering, we applied the ACMG/AMP guidelines for variant interpretation and classified seven variants, across seven genes, as either pathogenic or likely pathogenic. Through genetic drift, all seven variants, are highly enriched in the Amish compared to nonfounder populations. In total, 14.7% of Lancaster Amish individuals carry at least one of these variants, largely explained by the 13% who harbor a copy of a single variant in APOB. Other studies report combined frequencies of pathogenic/likely pathogenic (P/LP) variants in actionable genes between 2.0% and 6.2% in outbred populations. The Amish population harbors fewer actionable variants compared to similarly characterized nonfounder populations but have a higher frequency of each variant identified, offering opportunities for efficient and cost-effective targeted precision medicine.

Returning individual-specific results of a dementia prevalence study: insights from prospective participants living in Switzerland

OBJECTIVES

To explore prospective participants' preferences regarding the return of their individual-specific results from a dementia prevalence study (a probabilistic diagnosis of dementia).

METHODS/DESIGN

We conducted a qualitative study with 22 individuals aged 45 to 86 and resident in the Canton of Ticino (Switzerland). Participants had previously joined the validation phase of an epidemiological study into dementia and its impact.

RESULTS

We found that individuals welcome the return of their individual-specific results, provided these meet a number of validity, clinical, and personal utility criteria. They justify researchers' duty to return study findings with the principles of beneficence (eg, providing information that can help participants' medical decision-making) and justice (eg, acknowledging participants' efforts to help research by sharing their personal information). Furthermore, individuals anticipate societal benefits of the return of individual specific study findings, including improved interpersonal relationships among individuals and decreased dementia-related stigma.

CONCLUSIONS

Our findings suggest that researchers should address the return of individual-specific study results early on during study design and involve prospective participants in identifying both the conditions under which results should be offered and the perceived individual and societal benefits returning can have.
