QR Codes for Medication Adherence Tracking: Blister Pack Scanning and Remote Monitoring

1. The Adherence Problem

Non-adherence to prescribed medication causes preventable hospitalisations and disease progression. A QR on a blister pack can connect the physical act of taking medication to a digital log.

2. Scan to Log

The patient scans a QR on the blister pack when removing a tablet. The scan logs the timestamp and dose number. The caregiver or clinician sees the log remotely.

3. Smart Blister Packs

Some manufacturers print unique QR codes per dose cavity. Scanning the QR for a specific cavity confirms that dose was taken, creating a tamper-evident dose record.

4. Caregiver Alerts

If a scan is not recorded within a defined window of the scheduled dose time, the system sends an alert to the caregiver. Non-critical missed doses are logged; critical missed doses trigger a call.

5. Regulatory and Privacy Notes

Medication adherence data is sensitive health information. Storage, access, and sharing must comply with HIPAA, GDPR, or applicable local law. Obtain explicit informed consent before monitoring.
