UK LLC makes available a number of ‘core’ files with each project, including the core ‘denominator’ file.
This file serves as the UK LLC’s ‘spine’ as it incorporates all participants across all LPS.

Each project in the TRE is automatically provisioned a file named ‘CORE_denominator_file1_v0000_YYYYMMDD’.

The date in the dataset name relates to the “File 1” freeze (permissions) that a project is fixed to. Participant permissions are correct and applied to each dataset as of this date, and updated by the LPS on a quarterly basis.

The core denomininator includes:

  • has one row per UK LLC participant

  • inthe name of the LPS to which they belong

  • all UK LLC configurable permissions for the different domains of data (e.g. NHS England, place-based).

The denominator file enables users to:

  • calculate linkage rates (when joined to linked datasets)

  • contextualise LPS participants within UK LLC in relation to the LPS datasets.

UK LLC also provides ‘core’ datasets based on NHS England and place-based data.

More details to be added shortly
