A personal health record (PHR) is a health record where health data and other information related to the care of a patient is maintained by the patient. This stands in contrast to the more widely used electronic medical record, which is operated by institutions (such as hospitals) and contains data entered by clinicians (such as billing data) to support insurance claims. The intention of a PHR is to provide a complete and accurate summary of an individual's medical history which is accessible online. The health data on a PHR might include patient-reported outcome data, lab results, and data from devices such as wireless electronic weighing scales or (collected passively) from a smartphone. Definition The term "personal health record" is not new. The term was used as early as June 1978, and in 1956, there was a reference was made to a "personal health log." The term "PHR" may be applied to both paper-based and computerized systems; usage in the late 2010s usually implies an electronic application used to collect and store health data. In the early 2000s, healthcare organizations began to propose formal definitions of the term. For example: It is important to note that PHRs are not the same as electronic health records (EHRs) or electronic medical records (EMRs), which are software systems designed for use by health care providers. Like the data recorded in paper-based medical records, the data in EHRs are legally mandated notes on the care provided by clinicians to patients. However, generally there is no mandate requiring patients to track their own health data. Like EHRs and EMRs, PHRs may still fall under the regulatory scope of governments, depending on their origin, but rigorous regulatory protection of their data is still lacking in parts of the world. PHRs can contain a diverse range of data, including but not limited to: Applicable diagnoses . medications, including over-the-counter and alternative treatments Past medical and surgical interventions There are two methods by which data can arrive in a PHR. A patient may enter it directly, either by typing into fields or uploading/transmitting data from a file or another website. The second is when the PHR is tethered to an electronic health record, which automatically updates the PHR. Not all PHRs have the same capabilities, and individual PHRs may support one or all of these methods. In addition to storing an individual's personal health information, some PHRs provide added-value
