Overview

• Integrating electronic patient records.
• Data integration challenges.
• Successes in biological data modeling.
• Group details.

Current HCLS Activity

• BioRDF — model and query biological processes
• COI (Clinical Observations Interoperability) — use cases for common clinical data model

Electronic Patient Records Integration.

Requires shared terms:

• Alice measures Blood Pressure (血圧).

  test1 systolicBP "120"^^:mmHg .
  

• Bob measures supine (仰向け) BP.

  test7 systolicBP "118"^^:mmHg ;
        bodyPos    supine .
  

• Eve measures left arm BP with a cuff.

  test3 systolicBP "121"^^:mmHg ;
        location   leftArm ;
        device     BPcuff .
  

Study Data Tabulation Model (STDM)

What is a Blood Pressure?

• systolic, diastolic
• units (mm of Hg, bar, ...)
• extensible context (measurement location, patient position, activity, ...)

Reuse Issues

• These BPs are not exactly the same
• These BPs are close enough for many purposes
  • patient history in emergency room.

  • SELECT ?bp
    WHERE { ?test systolicBP ?bp }

• They can be distinguished when necesary.
  • drug response statistics

  • SELECT ?bp
    WHERE { ?test systolicBP ?bp ;
            location    leftArm ;
            device      BPcuff }

Challenges

• Social
  • patient privacy
  • health care proviser collaboration
• Technical
  • data unification
  • modelling

Data Unification

Integrating large, independent databases:

• Historically difficult
• Easier with Semantic Web
• Proven on bilogical data in the Banff Demo results
