Referral Assessment Redaction with anonym.plus

Pull identity from the referral assessment and keep the clinical history.

In simple terms, PII redaction is the on-device process of finding and masking personally identifiable information in a document before it is shared.

Redaction here means removing personal identifiers from a referral assessment. These pages hold dense personal history. The Data Protection Act 2018 and the NHS Code of Confidentiality govern these records. anonym.plus does the work on your machine. Sharing a referral assessment between services also sits under the Caldicott Principles, given statutory footing by the National Data Guardian for Health and Social Care Act 2018 — they set the information-governance test for whether a disclosure between providers is justified.

When this applies

The document was sent from an NHS Trust's single point of access (SPA) team to a receiving community mental health team, and lists the client, an emergency contact, and a prior provider. You want to file a sample for staff training, fully de-identified.

How anonym.plus handles it

  1. Open the document in anonym.plus on your device.
  2. Local OCR reads scanned questionnaires too.
  3. It flags client and contact names, dates, and providers.
  4. Review each flag and keep the history fields.
  5. Replace each value with a label, or hide it.
  6. Save the clean copy. The source stays local.

Limitations & cautions

These documents gather more detail than later notes. The tool removes named identifiers. You still review long free-text answers for a stray clue before you share the copy.

Frequently asked questions

Why are referral assessments sensitive?

They collect a full history at once: contacts, prior care, and personal events that a shorter note would never gather in one place. That density means more identifiers to catch, which the tool flags for you across the whole document.

Are emergency contacts removed?

Yes. A named relative or friend listed as an emergency contact is an identifier in its own right. The tool flags each one so the client cannot be traced through a contact even if their own name is already hidden.

What are the Caldicott Principles, and do they apply here?

They are the UK's long-standing information-governance test for sharing confidential patient information between organisations, now backed by the National Data Guardian for Health and Social Care Act 2018. A fully de-identified training sample never triggers that test, because it no longer identifies anyone the principles are there to protect.
