Electronic health records (EHRs) are a digital version of a patient’s medical, family, and personal history, collected from multiple sources. It includes protected health information (PHI) such as prescription information, laboratory test results, radiology images, and billing information. Electronic medical records (EMRs), by contrast, are a digital version of a patient’s medical chart collected from a single source. It is more focused on a patient’s medical history that can be quickly referenced during patient visits. Both types of records contain protected health information (PHI), however, EHRs typically contain significantly more PHI.
