Question to the Department of Health and Social Care:

To ask His Majesty's Government which secure data environment is used by NHS England’s Cohorting as a Service system; and whether this is used by all current cohorting service projects.

Cohorting uses the same underlying technology platform as NHS England’s Secure Data Environment service. Cohorting is carried out in other national programmes such as screening, which do not use the Cohorting as a Service system. There are forms of cohorting for other purposes such as population health and research; the Cohorting as a Service system is not currently intended to be used for these.
