Current Danish guidance stipulates, that the physician responsible for treatment must assess, if resuscitation is medically indicated in patients with life-threatening illness. Nevertheless, terminally ill patients without medical indication for resuscitation are still asked about preferences for resuscitation rather than informed about the decision not to resuscitate. This review describes clinical dilemmas, which may arise, if these legal rights are misinterpreted. It provides a communication guide designed to assist physicians communicating with patients about the decision to resuscitate or not.
