An Electronic Health Record (EHR) is an electronic version of a patients medical history, and may include all of the key administrative clinical data relevant to that persons care under a particular provider, including demographics, progress notes, problems, medications, vital signs, past medical history, immunizations, laboratory data and radiology reports. EHRs are designed to be used by multiple care providers and healthcare organizations. This facilitates sharing accurate data over time. Without EHRs, patients and/or care providers would still bear the administrative burden of arranging the transfer of the medical records to another care provider or multiple care providers.
