REPORT ON THE CLINICAL WORKSTATION AND CLINICAL-DATA REPOSITORY UTILIZATION AT UNC HOSPITALS

On December 1, 1993, we implemented version 2.1 of the Clinical Workst ation-Clinical Data Repository application in the Ambulatory Care Cent er. This version of the workstation allowed access of laboratory data from the clinical data repository that had been populated by a real-ti me HL7 interface between the Clinical Data Repository and the Laborato ry Information System. This implementation completed a major part of t he Clinical Workstation project. Also in December, we implemented a se curity system that records the date and time, user logon code, clinica l workstation functions used, and the patient medical record number on whom data were displayed. In addition to the security function, this system has proven to be a valuable tool in evaluating the utilization of the clinical workstation and is the source of the data presented in this paper.
