1 August 1990 HIS-PACS coupling in perspective
Author Affiliations +
Within the framework of the Dutch PACS project (a cooperation in the PACS field of BAZIS, the Utrecht University Hospital and Philips Medical Systems) a coupling between a HIS and a prototype PACS was realized and evaluated during clinical practice. This one-way coupling is a first step towards a so-called Image Information System, which can be seen as (logically) one system instead of two (a HIS for storage and retrieval of administrative and medical data, and a PACS for the images). The BAZIS/HIS is an integrated HIS, containing about 70 subsystems including a RIS, which is now used in about 40 hospitals in the Netherlands. The main reasons for coupling/integrating a HIS and a PACS can be summerized as: a) the user need for both functional and information integration and b) the need to have access to HIS data for optimizing image database and network management in order to get acceptable response times. As follow-up to the paper presented in the 1989 conference this paper will focus on the experiences gained with this one-way coupling. The event-driven communication took place by sending messages from HIS to PACS in ACRNEMA format. From these experiences recommendations for a next phase: a two-way link between a HIS and a PACS will be given. The necessity for bidirectional datatransfer will be discussed. Directions for future research e.g. on prefetching strategies will be pointed out.
