This study showed that knowledge of patients' values and preferences is very important to properly adapt the giving of medical information and to further the process of shared decision-making. Shared decision-making (SDM) trainings should consider different strategies of talking about values. The right strategy depends largely on the patient's preferences in communication. To be aware of the role of values in SDM and to be able to switch communicative strategies might prove to be of particular value. A more systematic evaluation of the patient's decision-making preferences as part of routine procedures in hospitals might help to reduce value-related barriers in communication.
