Screening Result De-Identification with anonym.plus

Healthcare Solution · Medical Imaging & Diagnostics · DPA 2018 & NHS Confidentiality Code

Screening result de-identification is the removal of patient data from the file under the DPA 2018 and the NHS Code of Confidentiality (common-law duty of confidence). anonym.plus runs it on your device. The outcome stays, but no person is named.

When this applies

A programme audit needs a batch of outcomes. The result column can stay, yet each name, date, and ID has to be hidden first.

How anonym.plus handles it

1. Open the file (CSV, PDF, or scan) on your machine.
2. Local OCR reads scanned pages so printed text is caught.
3. The tool flags names, dates, and patient IDs.
4. Review each flag and keep the outcome value.
5. Swap each ID for a token, or remove it.
6. Save the clean file. The source stays with you.

What you need to provide

• The file (CSV, PDF, DOCX, or image scan).
• An operator: Replace (swap), Redact (remove), or Mask (partial).
• Optional: a name map for follow-up rounds.

Limitations & cautions

An outcome paired with a small area or a rare trait can still point to a person. The tool clears the listed identifiers. You judge the rest before any release.
