[The 'interesting case' and patient privacy: handling patient data in medical education]

The use of patient histories has become an essential part of medical education. Patient histories are important for the relevance, effectiveness and appeal of medical education. The sharing of patient-related information in education and further training is expected to increase in the coming years. The sharing of patient information with colleagues, students or other interested parties can conflict with the rules protecting patient privacy. The most important rule in this context is that it is the patients who decide whether their cases can be shown to others for educational purposes. Patient consent is not required if the data or images used have been fully anonymized. If the information can be traced to the patient, consent is required, preferably documented in writing. The teaching physician is responsible for the storage, protection and destruction of patient data and for controlling access to information.
