What is OpenEHR?
OpenEHR is a virtual community working on interoperability and computability in e-health. It mainly focus on electronic patient records (EHRs) and systems [1]. In other words, we could think openEHR as the open source health equivalent of the iPod/iPhone platform – a technical framework which will allow any compatible application, organization or provider to share ‘plug and play’ access to standardized data. This is openEHR’s innovation – the focus on ensuring that the underlying health data is correct, robust and trustworthy [2].
OpenEHR Archetypes
The Concise Oxford Dictionary defines an archetpye as "an original model, prototype or typical specimen"[3].In openEHR, an archetype is the model for the capture of clinical information, allowing clinician and domain expert to design and collaborate of standardized clinical content specifications for electronic health records[4].Archetypes are a keystone of the openEHR architecture. Each archetype describes a complete clinical knowledge concept, such as 'diagnosis' or 'rest result'.The openEHR enables an openEHR-enabled software application to exchange clinical data in order to be understood and viewed in another unrelated clinical application[5]. With OpenEHR, clinicians are not only use of openEHR-enabled software and systems passively, but actively determine the possible breadth, depth and richness of patient data kept in EHR systems and directly affect the quality of patient care by creating, revising and updating archetypes[6].
There are four main classes of archetypes, each defined as part of the openEHR Reference Model, and each of the classes are used for different parts of the clinical recording and workflow processes[7].
- Composition Class: all information stored within EHR will be contained within this class.
- Section Class: mainly used to provide a framework to the Entry and Cluster class archetypes, for example, physical examination, social history ect.
- Entry Class: commonly used to group information together meaningfully and re-used in many different settings, for instance, blood pressure, weight, pulse etc.
- Cluster Class: used to represent fundamental domain patterns that are required in many archetypes and clinical scenarios - for example size, symptom, inspection and so forth.
The CEN/ISO EN13606 standard
The CEN/ISO EN13606 is an approved international ISO standard, which is designed to achieve semantic interoperability for EHR communication.[8]. The overall objective of CEN/ISO 13606 standard is to define a rigorous and stable information architecture for communicating EHR of a single subject of patient care between EHR systems, or between EHR systems and a centralized EHR data repository [9]. The CEN/ISO EN13606 standard defined a model driven software development methodology for health information systems [10]. Since health information distributed to different independent systems that may not be compatible, the solution is to transform openEHR archetypes into ISO/EN 13606 and vice versa by combining Semantic Web and Model-driven Engineering technologies [11]. As one of the most promising modeling efforts in the EHR system, Detailed Clinical Model (DCM) is proposed to transform its concepts into ISO/EN 13606/openEHR archetypes or HL7 models as well [12]. Therefore, clinical information distributed among several independent systems could be accessed by professional clinicians.
OpenEHR Foundation
Definition
The openEHR Foundation is currently a voluntary organization with no paid employees and is established as a not-for-profit company and community at UCL in London,facilitating the creation and sharing of health records by consumers and clinicians via open-source, standards-based implementations[13] [14].It is regulated under the UK Companies Acts 1985 and 1989. The name 'openEHR' has been registered internationally as a Trade Mark[15].
Vision
The vision of openEHR is the healthcare in worldwide routinely obtain benefit from ICT, especially for the life-long interoperable EHR and computing on EHR to improve the quality of health care and research[16].
Mission
The openEHR Foundation is organised under the four Programs[17]:
- Specification Program:develop open specifications validated by implementation;
- Clinical Models Program:develop clinical models (archetypes and templates), terminology interfaces;
- Software Program:develop open-source software and tools;
- Localisation Program:working with national standards organisations;
All of the above openEHR Programs will support health informatics education.
