[An information system for the management support of a radiology institute. Critical analysis and experience]

Abstract

The Radiology Information System (RIS) for the management of the Radiology Department at the Trieste University Hospital is here presented. It consists of 3 subsystems: the first one is devoted to the management of the patients archive and to the examination scheduling function, the second deals with the statistical and administrative reporting task, and the third manages the archives of scientific data. Each subsystem is analysed in details, in terms of functions, hardware, software, archives, and personnel. The actual implementations of such systems are considered, with respect to the main functions of the Radiology Department, on the basis of the authors' actual experience. An attempt is made to set aside features related to the local situation, thus providing useful data for different realities. Specific quantitative measures are presented, whenever appropriate, to provide a solid ground to explain and motivate the most relevant aspects relative to the management of the Radiology Department in general and of the RIS in particular. Workloads and/or execution times of the main functions were collected and the RIS has turned out to yield significant benefits (e.g., easier and more confident access to the information). On the other hand, the costs are not negligible and must be carefully planned during the projecting phase. Some expected future developments of the RIS are outlined: in the short run the network conversion is devised, and a functional integration among the subsystems; in the medium run an autonomous system is planned, and in the long run a connection is considered with a Picture Archiving and Communication System (PACS) and with the Hospital Information System (HIS).
