Report on the clinical workstation and clinical data repository utilization at UNC Hospitals.

Abstract On December 1, 1993, we implemented version 2.1 of the Clinical Workstation-Clinical Data Repository application in the Ambulatory Care Center. This version of the workstation allowed access of laboratory data from the clinical data repository that had been populated by a real-time HL7 interface between the Clinical Data Repository and the Laboratory Information System. This implementation completed a major part of the Clinical Workstation project. Also in December, we implemented a security system that records the date and time, user logon code, clinical 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.
