Making the connection: the VA-Regenstrief project

Abstract

The Regenstrief Automated Medical Record System is a well-established clinical information system with powerful facilities for querying and decision support. My colleagues and I introduced this system into the Indianapolis Veterans Affairs (VA) Medical Center by interfacing it to the institution's automated data-processing system, the Decentralized Hospital Computer Program (DHCP), using a recently standardized method for clinical data interchange. This article discusses some of the challenges encountered in that process, including the translation of vocabulary terms and maintenance of the software interface. Efforts such as these demonstrate the importance of standardization in medical informatics and the need for data standards at all levels of information exchange.
