Important Updates About the CTSI Clinical Research Data Warehouse

Important Updates About the CTSI Clinical Research Data Warehouse


Our Froedtert data warehouse toolset (i2b2, TriNetX, and Honest Broker) is now being refreshed on a weekly basis, every Wednesday at 5:00pm.


We have a new toolset called Jupyter Hub which contains all of the Honest Broker tables. This environment has both Python and R available to query across the tables for hypothesis testing and analysis. You do not need to use the i2b2 or TriNetX query tools to access the data in this environment, but access is limited, and knowledge of SQL and either Python or R is required. Contact Bradley Taylor for more information.


Research teams using i2b2 that are looking for patients with SARS-cov2 RNA testing results can find them under the Diagnostic Results (Labs) domain in Search by Names.

These patients can be further refined in i2b2 using the parameter pop-up box to select a specific result value.


  • Re-activation: If you have not used the CRDW toolset in a while, we will be happy to facilitate your re-activation. Please contact Kris Osinski.
  • Adding project team members, PIs, and delegates: If you would like us to grant access to new project team members, PIs (or their delegates) must complete a Data Release Agreement.
  • Other Questions: If you have other questions not covered in information above, please feel free to contact Kris Osinski directly.

NIH Funding Acknowledgment: Important Reminder – Please acknowledge the NIH when publishing papers, patents, projects, and presentations resulting from the use of CTSI resources by including the NIH Funding Acknowledgement.
