Nursing-note anonymisation removes personal details so the file is no longer health data under UK GDPR Art. 9. Once it is truly anonymous (Recital 26), it falls outside that scope. anonym.plus does this on a local device.
When this applies
Ward notes are special-category health records under Art. 9 and need a legal basis to use. Make them anonymous and you drop that burden for staffing, teaching, or audit.
How anonym.plus handles it
- Open the notes in anonym.plus on a local device.
- The tool spots patient names, care dates, room, and contacts.
- Swap each one for a non-reversible label to reach true anonymity.
- Keep no name map if you want the data outside that scope.
- Save the clean file on your device.
What you need to provide
- The file (DOCX, PDF, TXT, or EPR export).
- Replace, with the reversible map turned off for full anonymity.
- Optional language setting for Welsh or other tongues.

Limitations & cautions
True anonymity is a high bar. It is anonymous only if no one can re-identify it. If you keep a reversible map, the file is pseudonymous, not anonymous, and stays in scope. Turn off the map and apply the ICO motivated-intruder test first.
Frequently asked questions
Anonymous or pseudonymous — what is the difference?
Pseudonymous output keeps a key that can re-link it, so it stays personal data under UK GDPR. Anonymous output drops that key for good. Only then does Recital 26 take it out of scope.
Does it handle Welsh and other languages?
Yes. The tool reads many languages. That matters, since identifiers and date formats differ.
Can I reuse the file without patient consent?
Truly anonymous data is no longer personal data, so UK GDPR consent rules do not apply. You must be sure the result cannot be reversed.
