BRDIG/SDTM presentation by Steve Sandberg

<vipul> http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability?action=AttachFile&do=view&target=BRIDG-Project-Overview.ppt

start at http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability


steve: BAB: Bridge Advisory Board
... THC: architectural branch
... I'm participating in THC

[slide 3]

steve: sldie "BRIDG Content" shows the sources of BRIDG and where the terms came from
... all of these apps have submitted their models to the THC
... each of these models has vocabulary behind it
... BRIDG standardising these vocabularies

[slide 4]

steve: modelled as UML
... terms from HL7 datatypes

vipul: HL7 ciritisized for conflating acts with info

steve: we are trying to keep the consistent with the app space
... e.g. we separate study from study results
... there is a mapping document (spreadsheet) that maps imported models to BRIDG terms

[slide 5]

steve: defining semantics of classes and attributes, as well as terminology

vipul: i had heard that you would bind to SNOMED and
... RxNorm (vocab for medications)

steve: we are binding at the CADSR level to the classes

[slide 6]

entities: blue, Roles: yellow, Participation: red

[slide 7]

steve: circle in the LR corner is where meds fit

[slide 8]

steve: e.g. labs would show up in PerformedObservations and PerformedObservationsResults

[slide 9]

[slide 10]

<vipul> BRIDG - SDTM mapping available at: http://esw.w3.org/topic/HCLS/ClinicalObservationsInteroperability?action=AttachFile&do=get&target=BRIDG+Release+1.1+Mapping+Document.xls

steve: column F shows the mapping to BRIDG
... empty columns aren't mapped 'cause the didn't below in the BRIDG model

[slide 11]

vipul: lossless mapping possible?

steve: we are expecting changes on both sides to achieve that
... we are not expecting it on rev 1

Helen: what's a lossless mapping

vipul: roundtripping; don't map a Person to a GraduateStudent

steve: HL7 doesn't relate participation to participation. BRIDG does
... BRIDG has evolved a lot over the last year
... expect it's somewhat more stable now
... BRIDG reports through the ARCRIM committee

[slide 13]

steve: ASPIRE and CRFQ are also working on eligibility criteria

vipul: would like to have a prototype running
... we've scoped down to labs, meds and vitals
... probably too premature to present to them before we have a prototype
... do these (ASPIRE, CRFQ) extend to pharma?
... e.g. they appear to only model an academic medical institute

rachel: are mapping docs available?

vipul: posted above

steve: SDTM and other tabs show you the contributions to BRIDG

<vipul> q

eneumann: BRIDG site is mostly in the language of using UML tools
... are there pages for the less UML-endowed?
... e.g. images

steve: not yet

vipul, scribe is off for 5 mins

<vipul> ACTION: Create UML views of the BRIDG models: Helen [recorded in http://www.w3.org/2008/04/01-hcls-minutes.html#action01]

<vipul> Open Source Tools... Omondo: http://www.eclipsedownload.com

<vipul> Eric: Stanford's project for mapping the BRIDG model into OWL

<vipul> Eric: Lead by Amar Das' group at Stanford

<vipul> Eric: should be available sometime this summer.

Helen: if you want to translate from UML to OWL, there are fundamental differences
... e.g. is UML, X is a subClassOf Y, that is different from rdfs:subClassOf
... in UML they are adding more attributes to that class

eneumann: Standford has a axiomatic mapping of the BRIDG UML to OWL
... though they keep extra info as comments and annotations

steve: you can send Qs to me or Jyoti

vipul: over the long term, we want to map HL7/RIM to OWL and BRIDG to OWL
... for now, we'd like to work on the demo

<Helen> Eric N, is there is a pointer you can share about the "UML-.OWL" mapping in stanford?

<vipul> display agenda

ericP: do we have contacts for ASPIRE and CRFQ?

rachel: i know some ASPIRE folks

eneumann: i met charlie mead only twice

vipul: we can contact these folks when we're ready

<vipul> show agenda

rachel: anything that Charlie Mead does will come into BRIDG

Clinical Trials Ontology

vipul: we'll have a small meeting with holger, rachel, jennifer, and anyone else interested

Mappings from ACGT ontology to SDTM and other standards

vipul: how well does ACGT model SDTM?

holger_stenzhor: we have a student doing the work, but he's not a med professional
... current mappings are paper-only
... he developed his own mapping format in XML
... pointed me at a mapping engine being worked on in madrid
... i don't have any real feedback from them
... that's all i know now

vipul: will the greek group be willing to share?

holger_stenzhor: i expect so
... the mappings seem pretty straigh-forward

vipul: could they share a spreadsheet with us?

<holger_stenzhor1> http://wiki.healthgrid.org/index.php/ACGT:TOP_CRF_database/Pretreatment_histopathological_tumour_type

holger_stenzhor1: i can ask those guys if they can give us a small introduction
