Feasibility Query Tool

i2b2 (Informatics for Integrating Biology & the Bedside) is a web-based tool that allows scientists, students and staff to develop and run simple queries against a subset of data in the NMEDW. This gives users the ability to quickly determine the feasibility of conducting a study.

i2b2 lets you look for the number of patients that have been diagnosed with a disease, had a procedure, meet certain demographic criteria, had a laboratory result and were prescribed to a medication. Currently, only these variables are available to be searched. It can help you auickly determine the feasibility of conducting a research study or clinical trial and iteratively work through hypothesis generation by modifying your own searches.

The i2b2 system is already available to all Northwestern University researchers and affiliates. You can access i2b2 here from the NU Network or VPN. If you need help using i2b2, or have questions about your results, please contact

Visit the i2b2 system site, developed by Partners Healthcare, to learn more.
