QR Code Applications in Healthcare
Patient Wristband QR Codes
QR codes on inpatient wristbands are scanned before medication or tests to prevent patient mix-ups. Scanning displays electronic medical record information, enabling instant verification of prescriptions and allergy information.
Storing more data than barcodes, QR codes can include blood type and allergy information beyond patient ID. Wristbands wrap around curved surfaces, leveraging QR codes' distortion resistance.
Prescription and Medication Verification
QR codes on prescriptions are scanned during dispensing to accurately import prescription data into electronic systems, preventing transcription errors and improving dispensing safety and efficiency.
GS1 DataMatrix (a two-dimensional code like QR codes) is printed on pharmaceutical packages, storing product codes, lot numbers, expiration dates, and serial numbers, also helping prevent counterfeit drug distribution.
Medical Device Traceability
QR codes engraved on surgical instruments and medical devices track usage history, sterilization records, and maintenance logs. Tracing when instruments were sterilized and in which surgeries improves infection control accuracy.
Laser-engraved QR codes on metal surgical instruments withstand repeated washing and sterilization. Micro QR codes or rMQR codes may be used on small instruments.
