Excerpt

1.2. Historical overview VistA, an acronym for Veterans Health Information Systems and Technology Architecture, has its roots in the late 1970s. 1.3. VistA present DHCP system has evolved considerably since its initial deployment in 1983. For example, the implementation of a separate visual layer written in Delphi began the move to a ‘‘three-tiered’’ architecture. As a reflection of this evolution, its name was changed to VistA in 1996. VistA functionality has expanded greatly. At the beginning of 2002, VistA included 99 applications. ...........two new applications: the computerized patient record system (CPRS) and bar code medication administration (BCMA). 1.7. Computerized patient record system CPRS [25,26] represents a dramatic upgrade in the steady evolution of VistA. First, it advances a patient-centered approach to clinical computing rather than a department centered approach. Patient-centered computing began in the early 1990s with the release of health summary package. Second, it was VA’s first concerted effort at client server programming with a GUI. Third, its deployment at the VA medical centers enables a work process shift from paper-based charting to computer based charting. CPRS includes provider order entry and provider-entered electronic progress notes. Both are often believed to be difficult to deploy. CPRS was initially released in 1996. Its installation was mandated nationally in 1999 and virtually all clinicians in VA now use it. CPRS is an umbrella program that integrates numerous existing programs for the clinical user. Its tabbed chart metaphor organizes problem lists, pharmacy data, orders, lab results, progress notes, vital signs, radiology results, transcribed documents, and reports from various studies such as echocardiograms in a clinically relevant manner (Fig. 3). Providers using CPRS can enter, edit, and electronically sign documents and orders. 1.8. Bar code medication administration BCMA is a bedside application that validates the administration of medications. It was installed nationwide in the 1999*/2000 timeframe. BCMA enables nursing to use a bedside computerized medication administration record (MAR) implemented via wireless laptop computers and hand-held scanners.....To administer a medication, the nurse scans the patient’s wristband, the packaged medication, and the employee id card. The data are sent to an electronic MAR. Advantages include positive verification of patient identification and prescribed medication at the point of care, an immediate alerting capability to prevent the wrong medication from being administered, precise medication administration documentation noting on time, early and late dosing, and automated missing dose requisition.
