According to EHR Scope’s blog:
An Electronic Medical Record (EMR) is a system that enables physicians’ to have electronic patient charts. This system is solely for the physician, therefore, the legal record of a patient encounter is owned by the physician. The EMR is not interactive, and all patient information is stored within the physician’s computer.
An Electronic Health Record (EHR) is a system that focuses on the word ‘Health,’ which implies the scope of a patient’s well-being. The most important term that you must associate with an EHR is interconnectivity. An EHR has the ability to transfer data to other EHRs, hospitals, labs. It is about the PATIENT receiving the best care and is not dependent on the physical location of the patient.
Others define EHR as a longitudinal electronic record of patient health information generated by one or more encounters in any care delivery setting and includes a variety of patient information such as demographics, medications, past medical history etc.
