About

An electronic health record (EHR) is an evolving concept defined as a systematic collection of electronic health information about individual patients or populations.[1] It is a record in digital format that is theoretically capable of being shared across different health care settings. In some cases this sharing can occur by way of network-connected enterprise-wide information systems and other information networks or exchanges. EHRs may include a range of data, including demographics, medical history, medication and allergies, immunization status, laboratory test results, radiology images, vital signs, personal stats like age and weight, and billing information.

Terminology

The terms EHR, EPR (electronic patient record) and EMR (electronic medical record) are often used interchangeably, although differences between them can be defined. The EMR can, for example, be defined as the patient record created in hospitals and ambulatory environments, and which can serve as a data source for the EHR.[2][3] It is important to note that an EHR is generated and maintained within an institution, such as a hospital, integrated delivery network, clinic, or physician office, to give patients, physicians and other health care providers, employers, and payers or insurers access to a patient's medical records across facilities.

A personal health record (PHR) is, in modern parlance, generally defined as an EHR that the individual patient controls.
