(of 395,005attributions,or 20.27%)

Subject-Protocol Attributions

• 395,005 total attributions

• 126,533 verified by Medical Records

• 44,142 verified by IC systems

• 1,966 verified by users

• 363 unverified subjects “not on protocol”

• 236 verified subjects “not on protocol”

Re-using Data in De-Identified Form

• Look for unexpected correlations

• Pose hypothetical research questions

• Determine potential subject sample sizes

• Find potential collaborators

Access to De-identified Data

• De-identified data available to NIH intramural research community

• NIH researchers wanted access policy to ensure protection of intellectual property and first rights to publication

• Resolved through three means:– Association of data with an NIH PI– Status of protocol– Age of data

d) Active Protocol

Access to De-identified (Coded) Data

a) Data Outside Any Protocol

Period

b) Terminated Protocol – PI Gone

c) Terminated Protocol –

Capabilities of Data Model

• Storage of like data in meaningful model

• Preservation of original data details

• Can “promote” commonalities to main table

• Preservation of original meanings

• Queries based on users’ aggregations

Informatics Challenges

• Understanding data sources• Finding the right balance for unified data model• Modeling in the Research Entities Dictionary• Organizing the Research Entities Dictionary• Understanding researchers’ information needs• User interface (including Cognos customization)• Keeping up with report requests• Integration into multiple research workflows• Access to deidentified data• New policies on contribution and use

So What?• Easier access to protocol data from EHR• Easier access to archived data• Protocol data integrated from multiple sources• User empowerment• Concept-based queries• Data feeds to institute systems• Data model flexible but not too flexible• Rapid development timeline (under budget)• User adoption can be considered good• High user satisfaction• Success with NIH policy• Success with data sharing

Future Directions

• Finish historical data• Add more institutes and centers
