COI usecase teleconference 23June (today) 15:00 - 16:00

There will be a discussion of the use cases studied in the Clinical
Observations Interoperability HCLS task force today at 15:00 EDT
(21:00 CDT, 12:00 PDT). Interested members of HCLS are invited.

The COI task force is exploring the use of RDF mapping technologies to
ease data interoperability problems within and between health care and
clinical trials. Both ares require the recording of a patient's vital
signs, disease states, diagnoses, medications/treatments, etc.

A couple voiced goals are to:

  1 convince hospitals and clinics to use RDF as a data or at least
    exchange format.
  2 develop and recommend ontologies

So far, we have part of a Clinical Practices Ontology (CPO), based on
an expression of CDISC SDTM in RDF, and a Clinical Trials Ontology
(CTO), similarly derived from HL7/RIM. Cleveland Clinic has an
ontology called CPR which is built from scratch in RDF/OWL.

The predominant use case involves expressing a hospital's diabetes
patient database as RDF, in CPO, and expressing clinical trial
protocols as SPARQL queries on CTO. The mapping between CPO and CTO is
being written in n3
  http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability/InterOntologyMapping.html
and has been tested by executing CTO queries on the CPO data:
  http://www.w3.org/2008/04/DiabeticPatientsDataSet/end-to-end

The Cleveland Clinic CPR ontology aligns fairly well with the CTO
ontology. One perspective is that we could invest our time developing
the CPR and cherry-picking terms and classes from it to flush out the
CTO. The counter argument is that the community will be less motivated
by mapping successes if one side of the map is to CPR, rather than an
ontology based on the more familliar SDTM.

Come to the meeting and discuss this and you may win one of our
fabulous door prizes.
