Objectives Enable Patient Safety in clinical trials anonymisation of clinical site anonymisation of clinical data Build a semantically-interlinked medical information space recruit patients across European clinical data sets adverse event detection Support effective organization and execution of clinical trials embedding governance / legal / ethics in process Convergence Meeting: Semantic Interoperability for Clinical Research & Patient Safety in Europe 5/15
Safety First – Ethical & Legal Aspects Convergence Meeting: Semantic Interoperability for Clinical Research & Patient Safety in Europe Respect patients’ anonymity, data’s ownership and privacy Not possible to transfer or copy patient data from the originating institutions All machines that hold patient data are need to remain off- line Clinical data will not be identifiable and should not lead to the identification of a person’s identity (either directly or indirectly e.g. back-tracing) Strictly adhere to consent form requirements and all ethical and legal issues (European and national) 6/15
