Clinical Research Data Warehouse

The UNMC Clinical Research Data Warehouse (CRDW) is an IRB approved de-identified patient data set extracted from the Nebraska Medicine OneChart Electronic Health Record. The patient records are linked to other data sources such as the NAACCR cancer registry and CMS claims data. The Research Data Warehouse is built on the NIH funded i2b2 platform and allows investigators to query the data for research without separate IRB approval. The RDW currently contains selected, standardized data on over 600,000 patients and 3.5M encounters.
