Dear All,
There is an effort spearheaded by the AAFP to create a standard for the
content of a primary care record, the CCR. I've been in contact with
David Kibbe, MD, the "EHR Centrality" for the AAFP, who is wondering how
they can collaborate with the open-source EHR community.
well, they might start thinking about generic solutions, which
incorporate clinical models separated from their XML schemas for a
start. They need to consider:
- high-quality, clear clinical models like those being developed for
Australia, shown at http://oceaninformatics.biz/archetypes/
- a well-designed, ontologically sound model to underpin it, such as the
openEHR model. CDA is (sadly) no longer particuarly well designed, due
to the ad hoc and over-specialised collection of Entry subtypes, and
having been converted into an RMIM form. The XML-schema of openEHR will
be published very soon (it has taken a while to ensure it can be done
automatically from the models; we are nearly there).
Single level XML approaches don't have much long term future in my
opinion, because they don't properly separate clinical models from
information representation, which is required to allow compositional
clinical models and specialisable clinical models to be built
independently from the software.
I think that the ASTM report is right in one thing: the CDA and CCR are
two different beasts. The right way to do the CCR would be as a set of
archetypes and templates over the top of an openEHR schema. Then it is easy.
