title: [Modular project of the Picture Archiving and Communication System (PACS). Preliminary operational experience. I].
abstract: Since september 1988 a PAC System (Comm View by AT & T and Philips) has been operating in the Radiology Department of the University Hospital, Trieste. A research project is presently in progress aiming at providing factual evidence for the evaluation of this kind of systems as far as operational, technical, clinical and economic aspects are concerned. The general approach to this research consists in implementing and monitoring a PACS in a stepwise way, starting with a small system connected to some digital modalities only, in order to test the feasibility and effectiveness of the system within a Radiology Department, and to test the possibility of matching the PACS to the Radiological System. The present paper describes in detail the present configuration of this entry-level system and its technical features. The planned development (october 1989) is also depicted. Further developments devise at managing in an integrated way all the radiological images of the four hospitals of Trieste. At present, the PACS is currently used to manage and store on optical disks all the images acquired from the connected modalities plus the related reports, and to perform the reporting sessions for CT examinations (brain and abdomen). The present research effort is devoted to two main areas: clinical evaluation and operational analysis. The object of the operational analysis was the assessment of the impact of PACS on the operations of a Radiology Department. The general approach followed for this research consists in analysing the procedures as they are performed in the conventional way (manual operations), and comparing them to the way they are, or could be, performed using a PACS System (automatic operations). This stage of the project is divided into three phases, concerning respectively the analysis of the organization and operations before PACS, the analysis of the impact of PACS in its initial configuration and the forecast of the influence of PACS in its future setting. A first evaluation concerned the activities carried out from the moment the images are generated to the moment they are ready to be achieved. They include image acquisition, reporting, delivering and returning of images from the departments. The time required to carry out each of the activities involved was recorded, both in the manual and in the automatic version; furthermore, a more detailed analysis was performed on the reporting procedure. The conclusions reached through this analysis are that this kind of operation is mostly affected by the way the Radiology Department is managed, rather than by the tools employed.(ABSTRACT TRUNCATED AT 400 WORDS)
