Architecture • • • Data acquisition Database Controlled terminology User data entry Search tool

Data Model • Store similar data in main tables • Store extra data in generic tables • Can “promote” from generic to main table • Preserve original meanings • Queries based on concepts of the users

What is in BTRIS? • Clinical Center MIS (1976 -2004) and CRIS (2004 -) • Demographics • Vital signs • Laboratory results • Medications (orders and administration) • Problems and diagnoses • Reports (admission, progress, discharge, radiology, cardiology, PFTs) • National Institute of Allergy and Infectious Disease • Medication lists • Laboratory results • Problems • National Institute of Alcohol Abuse and Alcoholism • Clinical assessments

BTRIS Reports per Week

BTRIS Users and Subjects 115 BTRIS Users thru March 2010 619 Unique Protocols + 130 Non. BTRIS PIs = 245 BTRIS Beneficiaries 80, 073 Attributed Subjects (of 395, 005 attributions, 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

Access to De-identified (Coded) Data b) Terminated Protocol – PI Gone a) Data Outside Any Protocol Period c) Terminated Protocol – PI at NIH d) Active Protocol

Data Available for De-Identified Reports Total Subjects: 430, 196 Attributed to Protocol: 181, 068 Terminated > 5 yrs: 36, 467 Not attributed to any protocol: 249, 128

Data Available for De-Identified Reports Available Subjects – 285, 595 (66. 4%)

OHSR Exemption Process • Required for all de-identified data queries • Automated process replaces OHSR “Form 1” paper process for exemption

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
