EHR is the short form of Electronic Health Record, while PHR is the short form of Personal Health Record. From their full forms, it is very easy to figure out that both are not referring to the same thing. EHR is used by medical practitioners in the hospital for data collection. In contrast, PHR is a personal health record of an individual. Unlike in PHR, where the data can be documented either manually or electronically, the data in EHR is documented electronically.
EHR contains different data or information from different health providers, whereas the PHR contains certain information about an individual. Unlike EHR, which is created by the health practitioners, PHR is created by the user. A typical PHR usually reflects the special diet, medicine administered, symptoms of a particular disease, exercise programs, etc. In contrast, EHR contains comprehensive information about someone's health condition. With PHR, an individual can monitor their health, but EHR gives a medical practitioner a better understanding of the previous health issues of a patient so that better treatment can be provided.
