When should the National Opt-out be applied

Each patient’s NHS numbers MUST be screened against the national opt out list at NHS Digital prior to ANY of their data being entered onto the SSNAP webtool. 

As it is possible for a patients to subsequently opt out after a previous team has checked the database. All teams participating in SSNAP should not assume that because the record is on SSNAP it means the patient has not opted out. It is important that the national opt out database is checked prior to any data entry on SSNAP

This must be applied to any data entry that occurs after the 29th of September 2021 even if a patient had their stroke prior to this National Opt-out compliance deadline.
