Final answer:
The type of personal health record that allows portal access is known as a tethered personal health record. A tethered PHR enables patients to access their health data through an online portal connected to their healthcare provider's EHR system, which helps in maintaining up-to-date and private health records.
Step-by-step explanation:
The type of electronic personal health record that allows access through a portal is a tethered personal health record. Tethered, or connected, personal health records are linked to a specific health care organization's electronic health record (EHR) system.
Patients can access their information through a secure online portal, which not only facilitates the storage of personal health data but also ensures up-to-date information is directly fed from the healthcare provider's EHR system.
Sharing of digital records among health providers is a key method proposed to improve the quality and reduce the cost of healthcare in the U.S. However, it's important that these electronic records uphold a high standard of privacy to protect sensitive patient information.
