What is openEHR?
What is openEHR?An open specification for a health information model
capable of supporting an open platform ecosystem
vendor neutral
technology neutral
licensed to allow open and closed source business models

openEHR - key goalProvide specifications for an open eHealth platform
keeping the data in any openEHR system completely interoperable
regardless of programming language
regardless of human language
regardless of internal database technology
openEHR - SpecificationsNormal technical specifications with UML diagrams etc
openEHR Reference model how the health data is represented in a patient record
openEHR Archetype object model
how the clinical content definitions are represented separately from the Reference model
Two-level modelling
openEHR: Archetypesopen source computable models of discrete clinical concepts
Familiar components of a health record
Blood pressure, Body weight
Medication order, Family history
Urea, Creatinine results
‘Maximal dataset’ Capture as many clinical perspectives as possible
openEHR: TemplatesTemplates deliver the datasets by aggregating archetypes together
Key clinical endpoint and start point for generation of technical artefacts
i.e. openEHR archetypes and templates can be used directly
Class libraries, Message schema
GUI skeletons, API Profiles
AQL: Information-model querying
Information model querying, independent of the actual database querying
vendor/technology neutral querying
To query an openEHR system you only have to know which archetypes are in use.
However ….Building an openEHR back-end is easy
just follow the specifications
BUT building a high-quality openEHR back-end is hard
must understand archetypes
must support information-model querying
must be fast and flexible
This is not a trivial engineering exercise
The good news…You do not have to build your own openEHR back-end ‘CDR’…
over 10 providers of openEHR CDR services
the APIs are compact and easy to use once you understand the basic concepts
Database Compositions Template validation AQL GDL
