Data sets

Our national data sets collect information from care records, systems and organisations on specific areas of health and care. This is used to inform policy and monitor and improve care.

The Department of Health and NHS England tell us to collect data so they can learn about specific areas of policy interest and measure the progress of policy initiatives. We work with these partners and groups of health and social care professionals, patients, and IT systems suppliers to design and develop these collections.

Our standards and collections section, details the assurance for all national data sets.
