Description of activity and work performed
There are two key points at which a dose management system (DMS) can help us comply with the directive: the establishment and the use of diagnostic reference levels (DRLs) in radiological tests, and the transfer of information regarding patient exposure to the medical-radiological report. To meet these two goals it is necessary for the dose management system to be integrated with the rest of the information systems: Picture Archiving and Communication System (PACS), Radiology Information System (RIS) and Hospital Information System (HIS), that collect dosimetric and demographic information.
Although there is controversy among professionals about what information must be recorded in the medical-radiological report, it is clear that, the best way to process dosimetric information from the equipment, is through a dose management system. These systems have several tools for the automatic determination of the local reference levels (institution, autonomous region) based on the statistical analysis of the data provided by the modalities; and they can also warn the user, through an alert notification system (Fig. 2) of possible surpassing of these reference levels.
For all this, the correct identification of the patient, within the dose management system, and the codification of both the description of the studies/procedures and each of the series that compose them, is essential. It is also important for the DMS to have filtering tools that allow multiple selection of descriptors, from both studies and series (e.g. if we use radiographic projection as a series descriptor and we have several descriptors for the lateral projection (RL, LL, etc.) it will be necessary that we can group them in order to be able to calculate for example the reference level of a THORAX LAT).
