Cohort Discovery

Bunny and Relay are software tools that enable Data Custodians to provide Cohort Discovery services, allowing researchers to explore datasets securely and efficiently.

Cohort Discovery helps researchers and innovators to rapidly determine the size of the population which may be relevant to their research question within different datasets, without having to directly contact the individual organisations that hold the data.

Learn more about Cohort Discovery on the Health Data Research Gateway.

And the Cohort Discovery Implementation Guide on how to onboard to the HDR Gateway can be found here.

Cohort Discovery, originally developed as part of the CO-CONNECT programme, supported researchers to find and access COVID-19 data at pace, while ensuring peoples information was kept private and secure. If you would like to learn more about the CO-CONNECT development for the rapid discovery and data access to COVID-19 data, please read the CO-CONNECT Hybrid Architecture paper.
