A&E record anonymisation removes identifiers from an emergency department attendance — triage, assessment, and disposition — while the time-stamped course survives. The national flow for this data is the Emergency Care Data Set, mandated across NHS providers by a data provision notice under Health and Social Care Act 2012 s.259. anonym.plus works locally and keeps the intervals that make flow analysis possible.
When this applies
A&E departments also share anonymised assault data with community safety partnerships under the Information Sharing to Tackle Violence standard, with Crime and Disorder Act 1998 s.115 as the disclosure power. That only works if the extract really is anonymous before it leaves the department.
How anonym.plus handles it
- Load the A&E file into anonym.plus on your device.
- It finds triage, attendance, and disposition identifiers.
- Shift arrival and departure times while the intervals stay.
- Swap or black out the confirmed identifiers.
- Save the clean file on your device.
What you need to provide
- The A&E chart or triage file (PDF, DOCX, or EPR export).
- A date-shift option to keep elapsed-time analysis.
- An operator to suit the later use.

Limitations & cautions
A&E free text often holds incident locations and bystander names, which are indirect identifiers. Date-shift preserves intervals but breaks links to outside logs such as ambulance timings, unless you shift those by the same offset. Violence-prevention sharing under s.115 assumes the extract is genuinely anonymous, so verify that before you send it.
Frequently asked questions
How does date-shift keep A&E data useful?
Every date and time in one record moves by a single steady offset. The minutes between arrival, assessment, and departure are unchanged, so four-hour standard and flow analysis still work, while the real clock times that would place a person at a location are hidden.
What is Information Sharing to Tackle Violence?
It is the standard under which emergency departments pass anonymised assault details — type of weapon, location, time band — to community safety partnerships so violence can be mapped and prevented. Crime and Disorder Act 1998 s.115 provides the power to disclose, and the whole model depends on the data carrying no patient identity.
Are paramedic and bystander names removed?
Yes. Anyone named in the record can be flagged and swapped, not only the patient. Ambulance crew, accompanying relatives, and named bystanders are all identifiable individuals whose data sits in the same document.
