Abstract
ContextIn many cases, informed consent of participants is considered a prerequisite even for exclusively data-based medical research. In this context, a model of broad consent is being discussed. In Germany, the Medizininformatik-Initiative (Medical Informatics Initiative) has developed a proposal for broad consent for German hospitals which suggests a validity period of 30 years.Definition of the problemAgainst this background, the article discusses how the claim of consent beinginformedhas to be regarded in a temporal perspective. The practice of consent is here understood to be oriented towards the realization of well-being, personal sovereignty, and trust. In the context of medical research, an asymmetry of access to information between research participants, researchers, and data-storing institutions has to be assumed.Argument and conclusionThe article argues that in order to appropriately address this information asymmetry, a continuous dissemination of comprehensibly prepared information to research participants is necessary to enable personal sovereignty.
