Electronic medical records (EMRs) and electronic health records (EHRs) are often used interchangeably, but they have some differences. An EMR is a digital version of the paper charts in the clinicians office, containing the medical and treatment history of the patients in one practice. EMRs allow clinicians to track data over time, easily identify which patients are due for preventive screenings or checkups, monitor and improve overall quality of care within the practice, and check how their patients are doing on certain parameters such as blood pressure readings or vaccinations. EMRs are part of EHRs and contain patient registration, billing, preventive screenings, or checkups, patient appointment and scheduling, tracking patient data over time, and monitoring and improving overall quality of care. EHRs contain the patients records from doctors and include demographics, test results, medical history, history of present illness (HPI), and medications. EMRs and EHRs are valuable to cyber attackers because of the Protected Health Information (PHI) they contain and the profit they can make on the dark web or black market. EMRs are considered potentially one of the drivers for the transformation of healthcare, and from a patient care perspective, EMR is expected to improve patient outcomes, reduce medical errors, and increase patient satisfaction.
