Adverse event narrative redaction is the removal of patient and reporter identifiers from free-text case prose. It supports ICH E2B(R3) safety reporting. anonym.plus runs offline and keeps the medical account readable.
When this applies
A safety team shares a case story for review or training. The narrative names the patient, the reporter, and the hospital in plain text.

Limitations & cautions
A rare reaction plus a small town can still hint at one person. The tool removes named people, dates, and places. You weigh whether an unusual clinical detail in the prose needs a wider edit before the story is shared.
Frequently asked questions
What is an E2B narrative?
It is the free-text account of a safety case, sent in the E2B(R3) format to authorities. It often holds patient and reporter details. A redacted copy lets staff learn from the case without seeing who is involved.
Will redaction harm the safety detail?
No. The reaction, the suspect drug, the dose, and the outcome stay. Only the named people, places, and exact dates are removed.
Can I process a folder of narratives?
Yes. Point anonym.plus at a folder and it works through each file on your own device, one after another.
