MAR redaction is the removal of patient and staff IDs from a med chart. It meets the HIPAA Privacy Rule (45 CFR Part 164) for reuse. anonym.plus works locally and keeps the drug, dose, route, and timing grid that holds the value.
When this applies
These charts drive med-safety audits and pharmacy teaching. Each one names the patient and the nurse and carries the bed and MRN. Redaction keeps the grid, not the names.
How anonym.plus handles it
- Load the chart into anonym.plus on your device.
- It finds patient and staff names plus MRN and bed.
- The drug, dose, route, and time grid stays untouched.
- Black out items for audits, or swap them for analysis.
- Save the clean chart on your device.
What you need to provide
- The MAR or eMAR chart (PDF, DOCX, or EHR export).
- An operator (Redact for safety audits).
- Optional staff map for safety-event review.

Limitations & cautions
These charts are very tabular. Check that the signature and initials columns are mapped, since staff initials are easy to miss yet name the nurse. Drug names stay and are not treated as IDs.
Frequently asked questions
Are nurse initials IDs?
Yes. Initials and signatures name the nurse who gave the drug, so they go for de-identification. The drug entries stay.
Can I keep the dose data?
Yes. The drug, dose, route, and timing grid stays, so the chart is still useful for safety work.
Does this handle eMAR exports?
Yes. Printed charts and structured eMAR exports both work locally.
