BC|RQuest software is available to use by all authorised researchers and allows them to create their query and view the responses to their query. This software has been provided to CO-CONNECT ‘white labelled’ meaning there is no BC Platforms branding and the software has been rebranded as the HDR Cohort Discovery tool. BC Platforms help maintain the software (such as upgrades) but the server that runs the software is under the control of Health Data Research UK and hosted in the United Kingdom.
