Personal Health Records
There is an important distinction between electronic medical records (EMR) and personal health records (PHR). This distinction can be defined in multiple dimensions including who controls the data, what is the use of the data, what type of data are included, what is the source of data, and what are policies governing the data, to name a few. In great simplification, one can say that PHRs are controlled by patients and EHRs are controlled by providers. There are usually many medical records for the same patients.
It is also important not to confuse patient portals offered by providers with PHRs. These are not the same. This video gives brief overview presented by Dr. Farrokh Alemi.
