IHE needs SOLE!StandardizedOperationalLog ofEvents

The Problem

• Effective and Efficient Practice Management Requires Good Business Intelligence

• Until SWIM, there were no standards for representing the workflow steps in medicine

• A consequence is that it is hard to– Combine information from different systems into 1

BI tool for 1 enterprise– Compare information from different enterprises to

determine best practices

What is SWIM?

• SIIM Workflow Initiative in Medicine• First effort was set of about 140 events in

imaging department, about 10 states, and about 10 KPIs defined in terms of events

• SWIM was adopted by RadLEX and now have RadLEX IDs

• But, a Lexicon is not enough, just as DICOM was not enough to allow image interoperability

Basic Use Case

• Systems which perform events send messages to an event logger– Time, EventID (RadLEX), SystemID

• Events Consumers query Event Logger– BI tools for dashboards– WFEs for practice management

The Pieces vs Standards

• Event Creators: must use accept list of event terms (RadLEX – SWIM for medical imaging events. May expand outside imaging)

• Event Log: similar to ATNA Log?• Event Consumers: Query mechanism that may

mirror the ATNA log / REST?
