Analytics Services

CDSI provides various full service analytics services to support complex, ongoing research.

Northwestern Medicine Enterprise Data Warehouse (NMEDW)

The core resource for clinical research is the NMEDW. Created in 2007, the Northwestern Medicine Enterprise Data Warehouse (NMEDW) serves as the primary vehicle for data integration and transfer for both research and clinical operations. This dual-use model is one of the critical strengths of the NMEDW, and one that enables it to function as a unique bridge, integrating healthcare and research, as well as ensuring support from both the research and clinical partners. The NMEDW currently stores over 67 billion observations on 2.9 million patients. Each night it loads 44 million new data elements from 76 separate sources including electronic health records (EHR), pathology data from the hospital and research laboratories, biomarker data from research databases, and research transactional data from our eIRB and other institutional systems. The NMEDW has a mature data steward model, supported by an electronic workflow that enables rapid review of data requests.

Biostatistics, Epidemiology and Research Design (BERD)

Many of Northwestern University's Biostatistics, Epidemiology and Research Design (BERD) activities take place within the Biostatistics Collaboration Center (BCC). The BCC is housed within NUCATS and provides biostatistics expertise in all aspects of research including proposal development, study design, data management, statistical analysis, and manuscript preparation. In the past five years, BCC members have collaborated with more than 528 investigators in over 40 departments/divisions/centers across both Chicago and Evanston campuses and with all of our clinical partners.. The BCC consists of PhD faculty and Master’s level statisticians who are committed to and experienced in collaborating with clinical and translational investigators.
