Explanation:

A PHR, which stands for a public health record, can be used in three forms. First is a paper based system. Second is a portal based system on which data is uploaded by the healthcare institute and can only be viewed by patients and to professionals that are granted access to the patients records. And third is connected or tethered in which different institutes can access and retrieve information. However, this data is only for viewing and can only be changed by the data provider or the source of the data unless a healthcare professional has been provided special access to add to that patient's data file.
