The tissue biobanking of specific biological residual materials, which constitutes a useful resource for medical/scientific research, has raised some ethical issues, such as the need to define which kind of consent is applicable for biological residual materials biobanks.

ZusammenfassungEthische Aspekte von Biobanken-basierter Forschung werden zunehmend kontrovers diskutiert. In diesem Artikel wird die Debatte um ethisch angemessene Formen der Einwilligung in Biobanken-basierte Forschung nachgezeichnet. Nach einer Einführung in etablierte Einwilligungsmodelle skizziert der Beitrag kurz die Entwicklung alternativer Ansätze und diskutiert die damit verbundenen ethischen und regulatorischen Herausforderungen. Dabei wird dargestellt, welche ethischen Prinzipien in diesen Diskussionen eine Rolle spielen. Der Beitrag schließt mit einem Ausblick für Deutschland.

Background Dynamic consent has been proposed as a process through which participants and patients can gain more control over how their data and samples, donated for biomedical research, are used, resulting in greater trust in researchers. It is also a way to respond to evolving data protection frameworks and new legislation. Others argue that the broad consent currently used in biobank research is ethically robust. Little empirical research with cohort study participants has been published. This research investigated the participants’ opinions (...) of adding a dynamic consent interface to their existing study. Methods Adult participants in the Extended Cohort for E-health, Environment and DNA longitudinal cohort study who are members of the EXCEED Public and Participant Engagement Group were recruited. Four focus groups were conducted and analysed for thematic content. Discussion topics were derived from a review of the current literature on dynamic consent. Results Participants were in favour of many aspects of a dynamic consent interface, such as being able to update their information, add additional data to their records and choose withdrawal options. They were supportive provided it was simple to use and not intrusive. Participants expressed a markedly high level of trust in the study and its investigators and were unanimously happy with their current participation. No strong support was found for adding a dynamic consent interface to EXCEED. Conclusions Trust in the study researchers was the strongest theme found. Openness and good data security were needed to retain their trust. While happy to discuss dynamic consent, participants were satisfied with the current study arrangements. There were indications that changing the study might unnecessarily disturb their trust. This raised the question of whether there are contexts where dynamic consent is more appropriate than others. This study was limited by the small number of participants who were committed to the study and biased towards it. More research is needed to fully understand the potential impact of adding a dynamic consent interface to an existing cohort study. (shrink)

The economic aspects of biobanking are intertwined with the social and scientific aspects. We describe two problems that structure the discussion about the economics of biobanking and which illustrate this intertwining. First, there is a ‘sustainability problem’ about how to maintain biobanks in the long term. Second, and representing a partial response to the first problem, there is a ‘commercialisation problem’ about how to deal with the voluntary altruistic relationship between participants and biobanks, and the potential commercial relationships that a (...) biobank may form. Social scientists have argued that the commercialisation problem is inadequate as a way to construct the multiple tensions that biobanks must negotiate. We agree that the commercialisation problem is an inadequate framework; turning to alternative accounts of bioeconomy, we suggest that contemporary consideration of the economics of biobanking primarily in terms of participants and their bodily tissue may reproduce the very commodification of science that these scholars critique. We suggest that an alternative conception of the economics of biobanking beyond the logics of commodification, which may thereby allow broader questions about the social and economic conditions and consequences of biobanks to be posed.

The unknown nature of tomorrow’s research makes informed consent in biobank research a challenge. Whether the consent given by biobank participants is ‘broad’ or ‘narrow’, the ever present question remains the same: are new activities covered by the original consent? In this article, we focus on the meaning of, and the relation between, broad consent and re-consent in biobank research. We argue that broad consent should be understood as consenting to a framework—a framework which covers aims, core conditions for acceptable (...) use, governance and how these affect participants. Changes that alter the framework in a fundamental way call for re-consent. Three biobank cases of current international interest are used to debate when re-consent is an ethical necessity: whole-genome sequencing, data sharing and commercial utilization. These reflections give us a more nuanced view on what consent is for. We claim that the introduction of broad consents in biobank research has not represented a betrayal of individual participant interests, as some critics have asserted. Broad consents combined with the possible use of re-consent are in certain settings not inferior, but rather ethically superior to narrow consents. In population-based research biobanks, they allow for a reconciliation between individual interest and public matters in society at large. (shrink)

Appropriate information and consent has been one of the most intensely discussed topics within the context of biobank research. In parallel to the normative debate, many socio-empirical studies have been conducted to gather experiences, preferences and views of patients, healthy research participants and further stakeholders. However, there is scarcity of literature which connects the normative debate about justifications for different consent models with findings gained in empirical research. In this paper we discuss findings of a limited review of socio-empirical research (...) on patients’ and healthy research participants’ experiences and views regarding consent to biobank research in light of ethical principles for appropriate information and consent.

The current ethical norms of genomic biobanking creating and maintaining large repositories of human DNA and/or associated data for biomedical research have generated criticism from every angle, at both the practical and theoretical levels. The traditional research model has involved investigators seeking biospecimens for specific purposes that they can describe and disclose to prospective subjects, from whom they can then seek informed consent. In the case of many biobanks, however, the institution that collects and maintains the biospecimens may not itself (...) be directly involved in research, instead banking the biospecimens and associated data for other researchers. Moreover, the future uses of biospecimens may be unknown, if not unknowable, at the time of collection. Biobanking may thus stretch the meanings of inform and consent to their breaking point: if you cannot inform subjects about what their biospecimens will be used for, what can they consent to? Given that informed consent by individual subjects is the ethical gold standard, the seeming dilution of the concept in the context of biobanking is a profound problem. (shrink)
