An electronic personal health record (EPHR) allows patients to maintain and manage their personal health information privately and securely through an online application. EPHRs are beneficial because they make a patient's health records accessible anytime through mobile devices, which can be crucial in emergencies by providing medical personnel with important health details. While electronic health records are maintained by medical providers, EPHRs are owned by patients. Personal health records can contain a variety of health-related information to help patients and providers manage care. There are two main types of personal health records: standalone PHRs where patients directly input data, and connected PHRs that are linked to provider medical records and allow two-way sharing of information.
