Practicum Project"To improve patient outcomes, proactively identify chronic and high-risk patients in this new environment, and effectively manage their financial performance, healthcare organizations must be able to provide analytics at the point of service and rely on historical and longitudinal data to manage patient populations.”Health Research Institute (2012).

The Biomedical Informatics Core (BIC) of the Center for Clinical and Translational Research (CCTR) supports research with various data services.

i2b2 Informatics for Integrating Biology & the Bedside

• Name of the software and an NIH-funded National Center for Biomedical Computing based at Partners HealthCare System in Boston, MA.

• Software is open source and modular.• Developed for

translational research.• Doesn’t require IRB approval to

use at VCU• www.i2b2.org

Ontologies used in i2b2Librarians know ontologies!• International Classification of Diseases, Ninth

How can we help?

Be Aware of EHR Data Problems• Clinicians don't always document everything.• Billing codes aren't always the best

description of problem.• Too many variations of disease names.• Coding errors.• Narrative versus structured data.

Published Uses of EHR Data

Open DataLibrary and information professionals: • need to become more involved with semantic

web or users will reinvent wheel (i.e. ontologies)

• have the interpersonal and subject specialization for reference/consultation that IT doesn't have
