QR Codes on Patient Wristbands: Safety, Privacy, and Workflow

1. Safety-Critical Role

A patient wristband QR links to the correct patient record at every care step: medication administration, specimen collection, imaging, and surgery. Scanning catches misidentifications that visual checks miss.

2. What the Code Encodes

Best practice encodes only an opaque patient token, not personal data or health information. The token resolves to the full record in the hospital information system. This limits exposure if a wristband is read by an unauthorised device.

3. Privacy

The wristband is worn visibly. A token-only payload reduces risk; a direct patient identifier or health number in plain text is discouraged.

4. Wristband Durability

Wristbands face water, hand sanitiser, and physical wear. Use thermal direct labels on approved medical-grade wristband stock tested for durability in clinical conditions.

5. Workflow

1. Print at point of registration using the HIS-generated token. 2. Apply and verify at the bedside. 3. Scan and confirm identity at each care event. 4. Never re-use wristbands or tokens across patients.
