The new legislation, in particular the General Regulation on Personal Data Protection (GDPR), constitutes relatively demanding criteria on healthcare. However, the institute of medical secrets, which is an ancient medical practice and is part of various legal and professional regulations, contains many elements of today's protection of personal data and is not new among the professional medical public. Under the GDPR, however, there are steps that can be labelled as at least controversial. Such disputable measures have recently been to introduce electronic queue management systems, as we know from post offices. They are not a necessary measure for the protection of personal data in the waiting rooms of ambulances, they are not required by law, even with regard to GDPR and from the point of view of medical ethics are even at least problematic. If GDPR is applied in a similar way, it does not really benefit from the protection of personal data, and a useful tool like GDPR will be undoubtedly discredited.
