Screening result de-identification is the removal of PHI from the file under the HIPAA Privacy Rule (45 CFR Part 164). anonym.plus runs it on your device. The outcome stays, but no person is named.
When this applies
A program 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
- Open the file (CSV, PDF, or scan) on your machine.
- Local OCR reads scanned pages so printed text is caught.
- The tool flags names, dates, and patient IDs.
- Review each flag and keep the outcome value.
- Swap each ID for a token, or remove it.
- 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 tiny area or a rare trait can still point to a person. The tool clears the listed IDs. You judge the rest before any release.
Frequently asked questions
Does the pass or fail outcome stay?
Yes. The outcome is a clinical value, not a patient ID. It stays in place so the audit can count totals.
Can a list of subjects be cleaned together?
Yes. The app flags the ID fields in each row. A whole batch of outcomes is handled in one pass.
How do I keep rounds linked per subject?
Use a name map. Each subject gets one stable token. Follow-up rounds stay grouped with no real name shown.
