Ethics challenge for Sub-Saharan Africa big data research

A recent study highlights the need for the training of research ethics committees tasked with reviewing data-intense research protocols where data protection and sharing are important.

This is to better handle the ethical, legal and social implications of big data-related research, which are inadequately supported by legislative and enforcement frameworks, say the authors.

The sharing of research data is of increasing interest, with many funders advocating for, or even requiring researchers to share data sets as a condition of funding to maximise their utility and value.

However, write Nezerith Cengiz, Siti Kabanda, Tonya Esterhuizen and Keymanthri Moodley in University World News, despite the benefits of data sharing, finding the right balance between making data accessible and safeguarding privacy, preventing misuse, determining authorship, and protecting intellectual property, is challenging.

This challenge is greater in low- and middle-income countries like those in Sub-Saharan Africa (SSA) because of the gap in decision-making between data producers and users.

Some SSA countries have introduced data protection regulations in response to the recent digital revolution, initiating regulatory and legal data-protection frameworks to safeguard valuable information from exploitation, compromise and loss or theft – in other words, data governance.

These frameworks govern how certain data types are collected, processed and shared. This secures the privacy, availability and integrity of data through frameworks that set out how sensitive data, in particular, and privacy should be managed via the provision of tools and policies that restrict the unauthorised access, use and-or transfer of data.

Variations in legal and ethical frameworks



Yet legal and ethics frameworks that guide data-sharing and protect the interests of data donors in the region appear to vary considerably in their structure, terms, procedures and authority.

There are governance challenges relating to data protection in research, as not all countries in SSA have a legal framework to regulate the use of big data in research – that is, large volumes of a variety of raw data processed at high speed and frequency.

Instead, a spectrum of legal regulation ranges from the strict, comprehensive protection of data to no legal frameworks at all. Likewise, research ethics policies and guidelines suffer the same level of variability across the subcontinent where big data are concerned.

Unfortunately, data governance within SSA continues to be inadequately supported by legislative and enforcement frameworks.

Research ethics committees (RECs) have traditionally been established to protect the rights of research participants. However, they also play a key role in reviewing data-intense research protocols where data protection and data sharing are important.

The recent pandemic has placed increasing demands on RECs as research engaging with big data and artificial intelligence (AI) was accelerated.

Our study, published in the SA Journal of Science, aimed to determine REC members’ perceptions of data governance (safeguarding valuable information from exploitation, compromise and loss or theft) in SSA and to describe related challenges.

It is unclear how REC members navigate governance structures and processes and review such protocols. This study is part of a bigger project exploring the ethical, legal and social implications of big data and AI in SSA.

Findings


We found that only 58% of the REC members surveyed indicated that laws existed at a national level, with the remainder indicating no knowledge or uncertainty about the existence of such laws.

More specifically, a quarter (24%) of REC members were uncertain about whether such frameworks existed within their respective countries or institutions.
Although just under two-thirds of respondents were unaware of laws relating to data-intense research, only half were aware of laws relating to the cross-border transfer of data.

This suggests that research data may be crossing borders without agreements or export permits in place. Suboptimal awareness of the existence of data protection laws or the lack thereof among REC members in the sample was concerning. This will impact negatively on how data-intense protocols are reviewed.

Most worrying is the apparent lack of legislative frameworks for the cross-border transfer of big data on the subcontinent and out of Africa to other parts of the world.

The lack of legal and ethics expertise within RECs was recognised as a challenge in adequately reviewing research protocols that related to big data, research transfer agreements and in developing frameworks and policies.

This is important because of the historical concern with data and samples leaving SSA in an unregulated manner, which raises concerns about exploitative research practices.

Notably, although our findings indicate the absence of Data Transfer Agreements (DTAs) or Material Transfer Agreements (MTAs) at some institutions within SSA, most respondents (74%) indicated that their RECs were still responsible for reviewing these legal documents with data sharing-related research protocols when required.

Training for ethical committees


This raises concerns about the quality of review being conducted on the Data Transfer Agreements or Material Transfer Agreements submitted to RECs.

A DTA is a legal contract governing the transfer of de-identified human subject data, or identifiable human subject data in cases where a respondent has given voluntary, informed and electronic consent.
In many countries in SSA, biological samples are regulated in legislation via MTAs.

However, data, and particularly big data, are excluded.
Respondents emphasised that these DTAs should be stringent, with importance placed on institutions instigating mechanisms to improve regulatory compliance.
Suggestions included consultation with legal experts in the development of new DTAs, or improvements to current DTAs to ensure that they are aligned to existing laws or regulations.

The implementation of access control systems that concentrate on standard criteria for data use and propositions may reduce the likelihood of data misuse, and may legally complement data transfer across borders.

Our study highlights the need for the training of REC members in Africa to better handle the ethical, legal and social implications of big data-related research. These members recognised a deficit in their experience and expertise pertaining to the review of research protocols involving big data and related research transfer agreements.

In addition, established RECs across SSA would benefit from the reformation of practices and oversight mechanisms, expertise and regulations to better cater for the big data research context.

Transparent, robust and standardised data governance may promote shared ethical values to conduct research with big data on the subcontinent.

Equipping RECs with basic epistemological advantages, in the form of skills and knowledge in big data, would allow them to better fulfil their roles in effectively reviewing data-sharing protocols.

Abstract

Interest in the governance of big data is growing exponentially. However, finding the right balance between making large volumes of data accessible, and safeguarding privacy, preventing data misuse, determining authorship and protecting intellectual property remain challenging. In sub-Saharan Africa (SSA), research ethics committees (RECs) play an important role in reviewing data-intense research protocols. However, this regulatory role must be embedded in a context of robust governance. There is currently a paucity of published literature on how big data are regulated in SSA and if the capacity to review protocols is sufficient. The aim of this study was to provide a broad overview of REC members’ awareness and perceptions of big data governance in SSA. A descriptive cross-sectional survey was conducted from April to July 2022. We invited 300 REC members to participate in our online survey via Research Electronic Data Capture (REDCap). A total of 140 REC members, representing 34 SSA countries, completed the online survey. Awareness of data governance laws, policies and guidelines was variable across the subcontinent. A quarter of respondents (25%) indicated that national regulations on the transborder flow of research data are inadequate. Institutional policies on research data protection were also regarded as being inadequate. Most respondents (64%) believed that they lacked experience in reviewing data-intense protocols. Data governance and regulation in SSA need to be strengthened at both national and institutional levels. There is a strong need for capacity development in the review of data-intense research protocols on the subcontinent.

Significance
This is the first empirical survey in SSA in which awareness and perspectives of REC members have been explored specifically relating to the review of data-intense research protocols. Big data have raised new ethics and legal challenges, and this survey provides a broad overview of these challenges in SSA. Our study confirms that knowledge and awareness of legislative frameworks and ethics guidance in SSA vary considerably where big data are concerned. The research results could be useful for a range of stakeholders, including RECs, data scientists, researchers, research and academic institutions, government decisionmakers and artificial intelligence (AI) coders.
