Abstract: Data processing system for patient data. The invention refers to a data processing system for the processing of patient data, which includes person identifying data of a respective patient and corresponding health data (GD), with a central system (3), which includes a database (4) storing the health data, and with terminal devices (1), which are connected with the central station for the request of health data from the database and/or for the input of health data into the central database. According to the invention, health data is stored in the central database without assignment to person identifying data, a data record identification code (DIC) being assigned to a health data set of a respective patient, where a retrieval of the health data set necessitates the input of the corresponding data record identification code. The invention can be used e.g. for a system managing patient data records.
