[From a registry to a clinical information system. Development of the Datacor system at the surgery department A, Rikshospitalet].

: Based on a simple register for thoracic and cardiovascular operations a modulated system has been built up at Department of Surgery A. The register covers waiting list, a basic patient record, extensive operative data, the postoperative course and the final outcome. A local area network includes 36 microcomputers with approximately 75 users. Owing to lack of commercially available programs, local applications based on dBase have been developed. In this article we discuss our positive experiences from use of the local system with respect to administration, quality assurance and local research, its future place within a larger hospital system interconnected via a backbone, the need for better support and graphic user interface.
