A fully archetype-based openEHR clinical system covering a number of hospital departments in the Ljubljana Medical Centre. The experience in construction of this system and its ongoing development shows that the openEHR archetype, template and querying approach can change the rules of software engineering economics.
Married to standard IHE services, the overall system is proving extremely flexible and adaptable to the continuous stream of new requirements.
This presentation covers the experience and lessons from this system over its 2 year development lifecycle, and discusses how it can inform strategic thinking for EHR / CDR development in three key areas:
1. the use of openEHR archetypes and templates to flexibly and efficiently store and retrieve all clinical content
2. the power of the Archetype Query Language (AQL), it's use in clinical applications and decision support systems
3. a new approach to enhance the IHE ecosystem with content querying capabilities based on archetypes enabling answers to population queries
