CIDR 2007


Foreign dataspaces
Foreign Dataspaces

Data sources seem to appear by spontaneous generation

Often up to someone else to interpret them

Description can be minimal, lacking or wrong

CIDR 2007


Rxsafe dataspace
RxSafe Dataspace

Medication records

Assisted living facilities, Primary care clinics, Hospital, Pharmacies

Standards for medication information

  • National Drug Code Directory (NDCD), FDA, packaged drugs

  • RxNorm, NLM, describing clinical drugs

  • National Drug File – Reference Terminology (NDF-RT), VA, drug classes

CIDR 2007


RxNorm Published Structure[RxNorm: A Guide for the Perplexed, http://www.nlm.nih.gov/umls/rxnorm/rxnorm_guide.pdf]

CIDR 2007



Issues
Issues

  • Internal properties of sources

    What is a key, foreign key in NDCD

  • Generic vs. domain-specific structure

  • Comparability

    Tradename (NDCD) vs. Brand Name (RxNorm)

CIDR 2007


Connectivity rxnorm and ndf rt
Connectivity: RxNorm and NDF-RT

Classes for 54%of brand names

Dataspace profiling
Dataspace Profiling

Interactive tool suite (Dataspace Workbench) for dataspace characterization and customization

CIDR 2007


Architectural framework
Architectural Framework

Modules for different property types, with 3 components

  • Probe: property verification or inference

    <c1,hasForm,c2>c1=clinical drug, c2=dose form

  • Switch: customization that exploits property

    hasForm(Clinical_Drug, Dose_Form)

  • Check: ensure updates don’t invalidate

    Might be easier than probe
