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
