Electronic Health Record

Electronic health records (EHR) digitally store patient diagnoses, test results, prescriptions, and allergy information. QR codes on patient wristbands enable instant access to records, and three-point verification (reading the codes for the administering staff member's ID, the patient's wristband, and the medication label, then confirming that all three agree) prevents medication errors while recording who administered what to whom.

QR-coded prescriptions eliminate transcription errors between hospitals and pharmacies. Standardized formats ensure interoperability across healthcare institutions.
