What do we mean data sharing in research • Individual level health research data • De-identified • Sharing beyond primary research team
Illustration Quinine vs Artesunate for severe malaria in African children • Randomised controlled trial in 11 sites in 9 countries • Quinine vs artesunate 1:1, death is the primary outcome • 5425 children with severe malaria enrolled • Artesunate was proven better than quinine Dondorp et al, Lancet, 2010
What are the arguments for sharing data? What are the arguments against sharing data?
Why data sharing? • Transparency • Cost effective • New uses for data already collected • Bigger more powerful datasets • Reanalysis – new findings • Different statistical methods • Better data quality overall • Respecting participants • Improve science • Improve health
Why not? • Confidentiality • Misuse of data • Rogue analysis, cherry picking • Extra resources • Data quality • Data curation is expensive • Primary researchers • Exacerbates existing inequality • Ownership issues • Group harms • Any moral objections • Consent issues
Types of consent Which do you think works best?
Consent • When data are collected and stored for research purposes, either specific informed consent for a particular use or broad informed consent for unspecified future use must be obtained from the person from whom the data were originally obtained. • The ethical acceptability of broad informed consent relies on proper governance. CIOMS 2016 Guideline 12 - Data Sharing
Challenges around broad consent • Consent for the primary study is challenging enough • Analogy –“I am late for a date….” • Is broad consent considered “informed” consent? (2 opposing views) • What about children? • What aspects of data sharing are considered most important to inform participants? • How to explain data sharing to potential participants? • Little empirical data

Some findings What information should be provided to participants?
Conclusions from our study Broad consent • Broad consent is imperfect, so governance is important • Information will have to be tailored per context – or we crowd out important information • Empirical research and *community engagement is important *More on community engagement if we have time….
What does governance mean? Having a review process eg.data access committee • Who is applying? • What will the data be used for? • Social value - improvement health and science? • How would the primary investigators be credited? • Any potential for group harms • Any moral objections to certain research • Any potential for breach of confidentiality • Data access agreement
Many research questions • What are the REAL harms and REAL benefits of data sharing? • Who should be on a data access committee? • What should their roles be? • How do we make it equitable?
Illustration Quinine vs Artesunate for severe malaria in African children • Randomised controlled trial in 11 sites in 9 countries • Quinine vs artesunate 1:1, death is the primary outcome • 5425 children with severe malaria enrolled • Artesunate was proven better than quinine Dondorp et al, Lancet, 2010
The study was funded by a charitable UK funder (except for drugs) • The drugs used were donated by a pharmaceutical company • No prior consent for data to be shared with third parties • The trial resulted in change in WHO policy for treatment of malaria • Artesunate registered in many countries • Study can/will never be repeated
Time to vote • Apharmaceutical company requests for data for registration of IV artesunate in USA • Researchers in Europe want to merge datasets of severe malaria to find out causes of mortality in severe malaria Vote: Should the data be shared with the pharmaceutical company? Should the data be shared with the European researchers?
Ethics guidelines are not enough Some actions • required • prohibited • encouraged • permissible • Some areas covered by guidance are relatively uncontroversial, others make a judgement in areas of ongoing controversy amongst competing ethical obligations eg new areas like data sharing • What can we do? Community engagement can help address some of these issues • Examples of community engagement…
