title: [Use of medical treatment data outside of the patient supply: best way pseudonymisation].
abstract: The use of data pending during the patient supply to research, quality assurance                     as also to education is desirable. However, this use is not allowed in every                     German federal land without approval of the patient. Just in the case of                     retrospective research an approval of the patient is often not to be received.                     For the use of medical routine data for the research the pseudonymisation is                     good therefore. Pseudonymisation is a procedure by which all person-related data                     within a data record is replaced by one artificial identifier. Therefore                     pseudonymisation facilitates the linking of medical data and the data                     identifying the patient only under certain, before defined and controllable                     conditions. Through that medical data can be passed on to third party without                     this third party being able to identify the person who the medical data belong                     to. Under consideration of the present possibilities of the information                     technology as also the available technical preparations for the use of the                     pseudonymisation and the advantages being inherent in the pseudonymisation the                     pseudonymisation represents the method of choice during the use of data of the                     patient supply to the research, quality assurance as well as education.
