Picture Archiving and Communications Systems are sophisticated computer systems designed to store and display medical images. It has been suggested that these systems may be more cost effective than film in practicing radiology because of better access to images by multiple users, better integration of information from multiple studies, and more rapid delivery of diagnostic reports to clinical physicians. Development of these systems is in its early stages and questions have arisen as to what functions an image management system should have and how it should interact with stand alone radiology information systems (RIS) and hospital information systems (HIS)1. Over the past decade, computer systems have undergone gradual reorganization from highly centralized hospital (or medical center) information systems toward decentralized departmental systems. The former systems often provided global functions but did not have the flexibility to meet the needs of individual departments. Some individual departmental systems were developed to meet specific requirements, but they were often unable to communicate with other systems within a medical center. Today many RIS’s have the ability to provide departmental management tools, as well as to communicate with external systems. In order to achieve a filmless environment, PACS and HIS must be integrated with RIS systems to provide the level of information currently available. An additional goal of these systems is to automate operations and reduce the workload for technologists, admission personnel, file room staff, and radiologists. In 1986, we developed a long-range plan to convert to an all electronic department through the integration of three stand alone systems: RIS, PACS, and HIS. Because of our experience with a fully functional RIS since 1981, we elected to use it as the center to which the remaining systems could be integrated. Utilizing the RIS as the hub provides continuity to the department while the other systems are being developed and will thereby reduce overall disruptions within the working department. An image management system was installed in 1987. This system was initially independent from the RIS and patient demographic data needed to be entered into both systems when a study was performed. Between January 1987 and October 1988, we have worked with the commercial venders to integrate the RIS and PACS. This manuscript will discuss our early experience in integrating an RIS to an expanding PACS system2.
