 So I just want to summarise the ethical considerations in research data sharing. There is plentiful international and national guidance which is consistent in supporting research data sharing and reuse. But ethics committees are particularly interested that research studies must satisfy certain quality standards and these are assessed during the ethical review process. There should be a plan that all researchers have to maximise the benefit of their research including the future use of research data and that plan should be evident from the application. The ethics committee is interested in seeing these future possibilities defined and having the privacy and confidentiality standards set out in the submitted documents and those submitted documents include not just the protocol but any agreements that they may be and also the participant information material. So it's absolutely paramount that participants are well informed about the current and future research that they may be with their data and that they are given options for consent to each. So that would be separate consent potentially depending on the nature of the research for a current research project and future research which would reuse those data. And in the subsequent research project the use of research data must comply with that prior consent and with any other agreements that may pertain with participants, community groups or organisations unless these are renegotiated.
