Jefferson i2b2 Research Data Mart• Built on “informatics for integrating biology and the bedside” (i2b2)

framework from the NIH-funded National Center for Biomedical Computing based at Partners HealthCare System (Harvard).

• RDM data are de-identified. Re-identification possible via an honest broker, who has access to a re-identification application.

• Currently > 40 million observations on > 400,000 patients. Data refreshed weekly.

Current uses of Jefferson’s Research Data Mart

i2b2 query interface is the primary access portal for identifying biospecimens available for research.

The RDM provides cohort size estimates for prospective studies grant applications, and is used in the design phase of clinical trials to estimate of recent patient population satisfying proposed eligibility rules.

The RDM provides comprehensive patient annotation for ongoing research projects.

And, in support of Personalized Medicine, the RDM is used in Next Generation Sequencing (NGS) studies to discover cancer biomarkers for targeted treatment of individual patients.
