The features of the proband advance directive concluded by the legislature stand in opposition to a successful implementation, particularly due to the necessary concrete clarification content far in advance for informed research participants. This article describes solution possiblities, which refer to the realization of the instrument of a proxy research authorization as well as the consideration of an advance research planning based on the advance care planning.
