Cohort Discovery

Cohort Discovery is a Gateway feature that allows users to carry out a more specific search and assessment on a subset of datasets listed in the Gateway, without having access to the underlying data.

Users can specify defined characteristics relevant to their proposed analysis (e.g. patients that don’t smoke aged between 18-30 and who live in England) through the Cohort Discovery user interface. This requirement is then sent as a query to multiple pseudonymised datasets, with results returned in the form of a numerical count of individuals that meet those criteria.

Undertaking Cohort Discovery before requesting access to the relevant data improves research productivity, by avoiding requests for data not suitable for the research need and by improving the specificity of future data access requests where a cohort of sufficient size is identified.

This collection shows you the datasets that are currently onboarded onto Cohort Discovery. Further datasets will be added over the coming months.
