VistAWeb is a portal accessible through CPRS (Computerized Patient Recordkeeping System), the graphical user interface for the ''Veterans Health Information Systems and Technology Architecture'' (VistA), the electronic health record used throughout the United States Department of Veterans Affairs (VA) medical system (known as the Veterans Health Administration (VHA)). This portal has been implemented throughout the VA system, allowing healthcare providers at remote VA facilities to view records contained within the VistA electronic health record system at the patient's primary facility. As originally created, the VA health systems has 21 regional data systems (VISN), each with some differences in data collection and storage. The usage of VistA throughout the VA has helped to standardize records, but there has until recently not been an easy way for accessing records from a different VISN service area. If a patient travels or is injured or sick and visits a VA facility far from their home, VistAWeb will allow the physician or other healthcare provider access to the records at that patient's home institution. == Introduction == Veterans Health Information Systems and Technology Architecture (VistA) VistAWeb is an intranet web application used to review remote patient information found in VistA, the Federal Health Information Exchange (FHIE) system, and the Health Data Repository (HDR) databases. To a large extent, VistAWeb mirrors the reports behavior of the Computerized Patient Record System (CPRS) and Remote Data View (RDV). However, by permitting a more robust and timely retrieval of remote-site patient data, VistAWeb is also an enhancement to CPRS/RDV. There are three ways to access VistAWeb. VistAWeb can be made available by adding it to the CPRS Tools Menu, and it can be selected as the default method of retrieving data from the Remote Data Available button in CPRS. These two methods are referred to as CPRS-spawned versions of VistAWeb. They are compliant with the Health Level 7 (HL7) Clinical Context Object Workgroup (CCOW) standards and therefore maintain context with the patient selected in CPRS. As a third option, VistAWeb can be accessed in a standalone mode from its website at (https://vistaweb.med.va.gov/ ). The standalone version of VistAWeb is connected to neither CPRS nor the clinical context management application. Standalone VistAWeb serves an important function for users who have been granted special access to multiple sites, such as for National Programs, Veterans Administration (VA) researchers, and others. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VistA Web」の詳細全文を読む スポンサード リンク
