BMC Clinical Data Warehouse for Research (CDW-R):
CDW-R pausing receipt of new data set extraction requests

Thank you for your interest in BMC CDW-R research data set extraction services. The research data set extraction request form is currently unavailable.

As announced in February, the BMC Health System is undertaking several data warehouse infrastructure improvement efforts leading up to Fall 2024. To ensure continued access to high-quality data for research purposes, the CDW-R must divert analyst efforts to data migration activities from April 1, 2024 to July 8, 2024. The only CDW-R service that will be impacted during the downtime is new data set extraction requests. More details are on the BMC CDW-R website.

Data set extraction requests that were not finalized by March 22 will be triaged for data extraction to begin when the downtime lifts. A finalized CDW-R data set extraction request includes all of the following: IRB determination/approval; account number provided to CDW-R; fully completed Research Data Request form; and, where relevant, appropriate data sharing agreements executed.

Please review the information below for assistance with CDW-R services that will continue during the downtime.

CDW-R will continue to provide the following services throughout the downtime.
  • For medical record pre-screens and prospective recruitment lists (both for existing projects and for studies starting recruitment during the downtime) – Please email to coordinate medical record pre-screen/recruitment lists services during the downtime.
