Consent and research governance in biobanks: evidence from focus groups with medical researchers

Much is known about patient attitudes to ethical and legal questions in the context of biobanking, particularly regarding privacy protection and consent. However, little is known about the attitudes of medical researchers who use biobanks for research to these issues. Four focus groups with medical researchers in the UK were conducted in 2010-2011. The study highlights a range of issues associated with the research oversight and consent process (including obtaining ethical approval to use biobank samples and particular concerns for international studies), the benefits and limitations of broad consent and the possibilities of revoking consent. Many of these issues originate in the relatively static consent processes that currently govern the biobanking process. However, it is now possible to develop reliable, dynamic processes using information technology that can resolve many of these ethical and legal concerns. The 'dynamic consent' approach therefore offers the opportunity to fundamentally transform the process of medical research in a manner that addresses the concerns of both patients and medical researchers.

Research priorities. ELSI 2.0 for genomics and society

We need an international infrastructure for the ethical, legal and social implications of genomic research.

Navigating the perfect [data] storm

Bioscience has recently undergone a series of knowledge-based and technological revolutions. A critical consequence has been increasing recognition of the need to invest in infrastructure. Good access to data (and samples) from multiple studies is axiomatic to the value of this infrastructure. Access must be streamlined, secure, and based upon transparent and ‘fair’ decision making. It must be clear who has created and who has used which data. Ethico-legal policies and guidelines, which reflect dominant local cultural and societal norms, must take account of the increasingly global nature of bioscience research. A robust data infrastructure must also be attentive to the translational aims and social impact of its knowledge generation. In order to maintain the trust of its constituency – the general public as well as professional, political, commercial stakeholders – it must develop mechanisms to take account of all of these perspectives. These considerations form the basis of an emerging data economy. Building on extant achievements and pursuing the ideas outlined here could revolutionise the way we use and manage large-scale data. They have critical implications for biomedical and public health research communities and will be of central relevance for healthcare managers and policy makers, governments and industry. However, if the major challenges are to be met we must continue to invest,both nationally and internationally, in developing the cooperative infrastructures that provide a complementary foil to competitive resourcing mechanisms that drive hypothesis-driven science.

Embedding biobanks as tools for personalised medicine

Many governments are seeking to improve the translation of medical research innovation by developing mechanisms to aid the flow of information between the laboratory and the clinic. The intention is that the combination of new research insights and the use of next generation sequencing technology in the clinic will lead to more and better personalised medicine outcomes. However, existing healthcare structures often maintain the sharp line between research and the clinic, which slows down the bidirectional flow of information that is needed to enable effective translation. At the same time, within the biobanking field, infrastructures are being built to enable more efficient and better quality research. As with translational research, there are a number of challenges for these biobanking initiatives. Questions remain as to the best way to utilise biobanks for translational research. Other challenges are how to ensure the sustainability of individual biobanks and the biobank infrastructures that are being developed. Sustainability requires public support for long-term funding, as well as the on-going commitment of patients and research participants to provide the raw material for biobanks and regular use by researchers. One possible solution to the challenges that are found in these two areas is to embed a biobank within the healthcare structure and to use it for healthcare and research purposes simultaneously. This paper discusses the CuraRata and the EnCoRe dynamic consent models that in combination could provide sustainability for biobanks and at the same time enable translational research.

ELSI challenges and strategies of national biobank infrastructures

National biobank infrastructures are now being implemented in several European countries. Individually, biobanks are invaluable as national research resources; collectively, they are the critical elements needed for the actualization of the pan-European biobank infrastructure. The national biobank infrastructures are confronted with a number of challenges of legal, ethical, political, societal, financial and educational nature which must be articulated and addressed in order to optimize the use of the biobanks in national and international research. The community of researchers involved with these biobanks has charted the most pressing issues experienced by the national biobanks in their nascent stages of development. Our findings reveal great commonalities in the nature of the challenges that the national hubs are facing. These challen ges and the strategies developed to address them are described in this paper

From patients to partners: participant-centric initiatives in biomedical research

Advances in computing technology and bioinformatics mean that medical research is increasingly characterized by large international consortia of researchers that are reliant on large data sets and biobanks. These trends raise a number of challenges for obtaining consent, protecting participant privacy concerns and maintaining public trust. Participant-centred initiatives (PCIs) use social media technologies to address these immediate concerns, but they also provide the basis for long-term interactive partnerships. Here, we give an overview of this rapidly moving field by providing an analysis of the different PCI approaches, as well as the benefits and challenges of implementing PCIs.

The tension between data sharing and the protection of privacy in genomics research

Next-generation sequencing and global data sharing challenge many of the governance mechanisms currently in place to protect the privacy of research participants. These challenges will make it more difficult to guarantee anonymity for participants, provide information to satisfy the requirements of informed consent, and ensure complete withdrawal from research when requested. To move forward, we need to improve the current governance systems for research so that they are responsive to individual privacy concerns but can also be effective at a global level. We need to develop a system of e-governance that can complement existing governance systems but that places greater reliance on the use of technology to ensure compliance with ethical and legal requirements. These new governance structures must be able to address the concerns of research participants while at the same time ensuring effective data sharing that promotes public trust in genomics research.

Consent forms in genomics: the difference between law and practice

Consent forms are the principal method for obtaining informed consent from biomedical research participants. The significance of these forms is increasing as more secondary research is undertaken on existing research samples and information, and samples are deposited in biobanks accessible to many researchers. We reviewed a selection of consent forms used in European Genome-Wide Association Studies (GWAS) and identified four common elements that were found in every consent form. Our analysis showed that only two of the four most commonly found elements in our sample of informed consent forms were required in UK law. This raises questions about what should be put in informed consent forms for research participants. These findings could be beneficial for the formulation of participant information and consent documentation in the future studies.

From genomic databases to translation: a call to action

The rapid rise of international collaborative science has enabled access to genomic data. In this article, it is argued that to move beyond mapping genomic variation to understanding its role in complex disease aetiology and treatment will require extending data sharing for the purposes of clinical research translation and implementation.

Towards a data sharing Code of Conduct for international genomic research

Data sharing is increasingly regarded as an ethical and scientific imperative that advances knowledge and thereby respects the contributions of the participants. Because of this and the ever-increasing amount of data access requests currently filed around the world, three groups have decided to develop data sharing principles specific to the context of collaborative international genomics research. These groups are: the international Public Population Project in Genomics (P3G), an international consortium of projects partaking in large-scale genetic epidemiological studies and biobanks; the European Network for Genetic and Genomic Epidemiology (ENGAGE), a research project aiming to translate data from large-scale epidemiological research initiatives into relevant clinical information; and the Centre for Health, Law and Emerging Technologies (HeLEX). We propose seven different principles and a preliminary international data sharing Code of Conduct for ongoing discussion.

From consent to institutions: designing adaptive governance for genomic biobanks

Biobanks are increasingly hailed as powerful tools to advance health research. The social and ethical challenges associated with the implementation and operation of biobanks are equally well-documented. One of the proposed solutions to these challenges involves trading off a reduction in the specificity of informed consent protocols with an increased emphasis on governance. However, little work has gone into formulating what such governance might look like. In this paper, we suggest four general principles that should inform biobank governance and illustrate the enactment of these principles in a proposed governance model for a particular population-scale biobank, the British Columbia (BC) Generations Project. We begin by outlining four principles that we see as necessary for informing sustainable and effective governance of biobanks: (1) recognition of research participants and publics as a collective body, (2) trustworthiness, (3) adaptive management, and (4) fit between the nature of a particular biobank and the specific structural elements of governance adopted. Using the BC Generations Project as a case study, we then offer as a working model for further discussion the outlines of a proposed governance structure enacting these principles. Ultimately, our goal is to design an adaptive governance approach that can protect participant interests as well as promote effective translational health sciences.

Correlates of constipation in people with Parkinson's

PURPOSE

To investigate clinical, demographic and dietary factors associated with constipation in a sample of community dwelling people with Parkinson's disease, recruited through a specialist outpatient clinic. Partners/carers provided a convenience control group.

SCOPE

Participants completed a baseline questionnaire (background information, diet and exercise, activities of daily living: mobility and manual dexterity, health-related quality of life (SF-12), stool frequency and characteristics, extent of concern due to constipation, laxative taking), and a four-week stool diary. The Rome criterion was used to determine constipation status. Multiple regression methods were used to explore the correlates of constipation. Baseline data were provided by 121 people with Parkinson's, (54 controls), of whom 73% (25%) met the Rome criterion. Prospective diary data from 106 people with Parkinson's (43 controls) showed lower proportions: 35% (7%) meeting the Rome criterion. Among all study subjects, i.e. Parkinson's patients and controls taken together, the presence of constipation is predicted by having Parkinson's disease (p = .003; odds ratio 4.80, 95% CI 1.64-14.04) and mobility score (p = .04; odds ratio 1.15, 95% CI 1.01-1.31), but not by dietary factors. Amongst people with Parkinson's constipation is predicted by number of medications (p = .027). Laxative taking masks constipation, and is significantly associated with wearing protection against bowel incontinence (p = .009; odds ratio 4.80, 95% CI: 1.48-15.52).

CONCLUSIONS

Constipation is disease-related, not a lifestyle factor. More research is needed on optimal management and laxative use.

Identifiability, genomics and U.K. data protection law

Analyses of individuals' genomes--their entire DNA sequence--have increased knowledge about the links between genetics and disease. Anticipated advances in 'next generation' DNA-sequencing techniques will see the routine research use of whole genomes, rather than distinct parts, within the next few years. The scientific benefits of genomic research are, however, accompanied by legal and ethical concerns. Despite the assumption that genetic research data can and will be rendered anonymous, participants' identities can sometimes be elucidated, which could cause data protection legislation to apply. We undertake a timely reappraisal of these laws--particularly new penalties--and identifiability in genomic research.

Assessing the privacy risks of data sharing in genomics

The protection of identity of participants in medical research has traditionally been guaranteed by the maintenance of the confidentiality of health information through mechanisms such as only releasing data in an aggregated form or after identifying variables have been removed. This protection of privacy is regarded as a fundamental principle of research ethics, through which the support of research participants and the public is maintained. Whilst this traditional model was adopted for genetics and genomics research, and was generally considered broadly fit for purpose, we argue that this approach is increasingly untenable in genomics. Privacy risk assessments need to have regard to the whole data environment, not merely the quality of the dataset to be released in isolation. As sources of data proliferate, issues of privacy protection are increasingly problematic in relation to the release of genomic data. However, we conclude that, by paying careful attention to potential pitfalls, scientific funders and researchers can take an important part in attempts to safeguard the public and ensure the continuation of potentially important scientific research.
