Biobanks are large-scale libraries of biological samples such as blood, tissue and DNA. They are integral to medical research, especially when conducting population-wide studies. However as biobanks contain human biological materials, ethical considerations surrounding the use of such samples cannot be overlooked. This article will outline some of the ethical standards and guidelines that biobanks must follow to protect individuals’ rights, focusing on the importance of informed consent, the rights to privacy and confidentiality, and right to withdrawal. Moreover, the article will cover the importance of benefit sharing, ensuring ethical oversight and return of the results back to individuals. Compliance of these ethical regulations ensures the protection of patients’ rights and helps further medical research. 

Informed Consent 

Informed consent is a process in which the patient voluntarily agrees to participate in the medical intervention following fully understanding the all necessary information about the medical intervention, including its risks and benefits. It is the duty of the healthcare provider (in our case biobank operator) to deliver the full scope of information about the medical intervention to the participant in a manner in which the individualin question will fully understand. Informed consent is a legal obligation in many jurisdictions across the world and therefore is an integral part of biobank participation.¹

Informed consent discussion includes: going over the nature of the procedure, risks and benefits associated with it and the potential effects on participant’s health, available alternatives, risks and benefits of the alternatives, and finally an assessment, often in a form of a Q & A of the participant’s understanding of the above outlined discussion points.¹ The agreement to participate in the medical intervention by the individual must be voluntary – by no means should anyone feel coerced to be a part of the medical intervention. 

In biobanks, informed consent would often encompass asking questions regarding retention of samples and patient’s personal information for a period of time and whether the samples can be used for studies. Moreover as the study progresses, the participants must be continuously informed throughout about their rights. 

Privacy and Confidentiality 

Privacy and confidentiality is another “pillar” of biobank’s patients rights. It involves ensuring protection of a participant's personal information from unauthorised access and maintaining an anonymous identity. In the case of biobanks, privacy and confidentiality is maintained by ensuring that personal information about the participant is never shared with the researchers.² 

Some of the methods by which biobanks can ensure privacy and confidentiality include data anonymisation and controlled access to the data and samples. In case of data anonymisation, biobanks often de-identify samples from the participants and assign code identifiers which cannot be traced back to the participants which provided this sample. Samples are then stored under these new codes in secure places under databases which prevent unauthorised access. Access of sample data is strictly limited to personnel of biobank and researchers, when required. Privacy and confidentiality is a patient’s right and it is encompassed in data protection laws. 

Right to Withdraw 

Participation in any clinical research study or biobank have the right to leave the study/biobank at any given time with no repercussions.³ Upon withdrawal, the samples and data must be removed from the biobank storage and databases. In the caseof biobanks, the samples must be destroyed according to clearly outlined protocols. 

Benefit sharing 

When a patient is participating in biobank study, they must be informed of any updates regarding research utilising their samples, especially if this research promotes greater advancements in medicine. In essence, in one way or another participants must benefit from such medical advancements or health improvements which came following their participation in research.⁴ 

Moreover, if there are any results obtained from a participant’s samples, they must be returned to the patient, for their own discretion. These results must be accompanied with sufficient information which outlines potential health implications and relevance to the participant’s own health. Individuals must also be allowed to opt-out of receiving results, if they prefer not to. 

Ethical Oversight 

For biobanks to operate, ethical oversight must be performed periodically to ensure that the biobanks comply with legislatures and ensure patient’s rights. Ethical oversight often consists of ethics committees and audit processes. Before biobanks can operate and before a clinical study using biobank’s samples begins, ethics committees have to review protocols and proposed practices to ensure they comply with ethical standards. During the operation of a biobank, any activity must be audited to also ensure ethical standards are being adhered and maintained. 

Conclusion

In conclusion, complying with ethical standards in biobank research is paramount for protection of participant’s rights. By obtaining informed consent, protecting privacy and confidentiality, allowing withdrawal if desired and returning results, biobanks can operate under ethical standards, with oversight from ethics committees and auditors to ensure continued compliance. Honoring a patient's rights not only safeguards individuals, but also fosters public confidence and ongoing engagement in clinical researchto help drive medical advancement forward.

FAQs

What are biobanks? 

Biobanks are reservoirs of human samples, which are used for research. These samples can include blood, tissue, DNA. Often, clinical researchers use samples from biobanks in their studies. 

What are the main aspects of biobanks’ patients’ rights? 

The core pillars of patient’s rights in biobank participants or at large, in any clinical study include informed consent, privacy and confidentiality, right to withdraw, benefit sharing. These are required by law when dealing with human specimens.
