Abstract

Intermountain Healthcare has designed and implemented a publish-subscribe (PubSub) infrastructure to support essential event processing workflows across our organization. A recent implementation of a commercial EMR highlighted the need to provide this capability on top of the EMR to support external applications and services that require access to triggering events within the EMR. A description of the PubSub architecture is presented. Use cases for health information exchange, public health reporting, and pulmonary embolism diagnosis that utilize PubSub are described, along with benefits of using the paradigm. Besides providing support for these external applications, the PubSub infrastructure allows additional event handling functionality not available in the commercial EMR. The open, standards-based nature of the design should allow other organizations to implement the system in their information systems environment.
