The meeting of the HL7 Working Group (WGM) held recently in Sydney, Australia Ocean Informatics, the company leads the openEHR platform and is based in Australia, showed a shift in its strategy.
Grahame Grieve, who has participated in HL7, openEHR as well as presented a plan to create a technical paper on the differences and similarities between HL7 and openEHR.
In the past the differences between HL7 and openEHR are public and conspicuous on both sides, but perhaps more insistently by openEHR continually insisted that this is the only platform that can meet all the needs of professionals.
develop Grahame The document will mark the differences between HL7 and openEHR, HL7 making it clear that define the interoperability standards their use in a flexible and adaptable to different needs of schools and environments.
This leads to very rich information models, and self in HL7, for one can not really make any assumptions about an application host, or station, must be an independent environment of the architecture of our electronic medical records. OpenEHR
not specify interoperability openEHR architecture specifies a medical history and behavior. The main difference leads to a different vision of how to model health data.
However, substantial areas of overlap: both approaches are based on the use of a model reference (a model of high-level information) and a layer of limited models.
In both environments is necessary to obtain information on the details of the clinical models, terminology, etc.
During the sessions of the working group meeting it was decided to create a feasibility project to see if models can be expressed openEHR clinical archetypes, with the transformation of HL7 templates. OpenEHR
has the tools that allow people with a clinical history to define archetypes - we hope that these definitions can be reused in the context of HL7.
One of the important steps of openEHR is to remove the speech reference model is better, this is not relevant in the current context. Having
greater cooperation will benefit all of us, there are many things we can learn from each other.
The process of innovation includes the study of their products through different eyes from time to time, and this is what makes organizations endure and consolidate.
Some may think it is the beginning of the end of openEHR but my opinion is that openEHR has landed and took land after a long time on the moon. Carlos Gallego carlos@cgallego.es
