Abstract
The Department of Veterans Affairs has developed a bidirectional HL7 - ACR-NEMA V 2.0 interface for connecting existing federal government hospital/radiology information systems (HIS/RIS) to commercial picture archive and communication systems (PACS). The interface has been in use since October 1993 at the Baltimore VAMC between the VA's HIS/RIS (DHCP) and a commercial PACS, and handles both text and image transfer. The text-only portion of the interface has been ported to work with a second vendor's PACS, and to work with the Department of Defense HIS/RIS (CHCS). Currently the interface is in production at two VA and three DoD sites. The common benefit experienced at all these sites is that passing patient, order, and report information directly from the HIS/RIS to the PACS greatly improves the flow of work in the Radiology Department. Image transfer to the DHCP Imaging System at the Baltimore VAMC demonstrated the advantage of providing `reference quality' (1K X 1K X 8-bit) radiology images to treating clinicians throughout the hospital. Experience has shown that the gateway must handle transactions between the HIS/RIS and the PACS quickly in order to keep up with the volume, and must provide an audit trail for system diagnostic purposes. Work is underway to construct a HL7 - DICOM gateway built upon the operational experience gathered from the existing interface.
