From the reading I've been doing lately about personal health records I have collated/synthesized twelve characteristics that a personal health record (PHR) should have.

1. Provide patient education
    Along with storing a patient's health records, a personal health record should provide education about a patient's conditions, surgeries, medications, etc.

2. Lifelong and comprehensive
    The information in a personal health record needs to consist of the entire health history of a patient and include all health care providers the patient has seen.

3. Accessible from any place at any time
    The personal health record needs to be accessible by the patient and the health care provider whenever and wherever it is required.

4. Provide health management tools
    Features need to include tools that allow the patient to record their data and compare it to what it should be so that the patient can improve their health.

5. Private and secure
    Obviously, this characteristic is very important.  The patient information, both entered by the patient and what comes from the Electronic Medical Record (EMR), needs to be kept private and appropriate (or even more than necessary) security measures need to be used to keep the data secured.

6. Capture self reported values
    A personal health record must allow a patient to enter their own information if the data is missing or incomplete in what exists.

7. Patient controls what data is entered into their PHR
    The patient is able to add items to their personal health record and is able to control what data is put into their PHR, like data from their electronic medical record.

8. Access to the patient's EMR data
    To increase patient adoption, a personal health record must have the ability to interact with a patient's electronic medical record.  Information should flow to the PHR from the EMR and the patient should be able to send data to the EMR (which can be accepted or rejected by the physician as needed).

9. Secure patient-provider communications
    Not only should a personal health record provide health management tools, but a PHR should provide patients a method to communicate with their physician(s) to ask questions, report health measurements, etc.

10. Patient controls who has access to their information in the PHR
    A patient should be able to share data in their personal health record to whomever they feel is appropriate.  The patient should be able to control this at the level of each individual item in the personal health record, like a single condition, medication.

11. Transparent
    An audit trail needs to be available to the patient to see where the data items came from that are in their personal health record, who entered it, who has viewed each item and when.

12. Interoperability
    The information in a personal health needs to be in a format that can be exported or shared between personal health records, electronic medical records, etc.
