Access Clinical Data for Research
The Boston Medical Center (BMC) Clinical Data Warehouse for Research (CDW-R) is a centralized resource to access patient-level and population-level data for research. CDW-R analysts extract clinical information from BMC's Electronic Health Records (EHR) and other health system-related data streams to leverage data for research. The CDW-R team also collaborates with Departments and Divisions to increase research infrastructure and better leverage data for research purposes.

Current Wait Times
If you are preparing for a study: CDW-R provides investigators with cohort size simple counts (i.e. aggregated data, not supplied at the patient level) to prepare for a research study or IRB protocol submission. Simple count services are free-of-charge. CDW-R aims to deliver aggregate data within 7 business days of a finalized request.
If you need data for a study: Research teams should plan for several weeks between submission of a finalized CDW-R data extraction request (including confirmation of IRB protocol approval/determination, confirmation of any special approvals, a fully completed CDW-R data extraction request form, and identification of an account number to pay for services) and receipt of the data.
Research teams are encouraged to plan according to the wait times below:
