What system is linked to patient portals?

The correct answer is EHRs (Electronic Health Records). Patient portals are typically integrated with EHR systems, which allow patients to access their health information online. This includes viewing lab results, scheduling appointments, communicating securely with healthcare providers, and managing personal health data. The link between patient portals and EHRs is critical because EHRs serve as the central data repository for patient information, thus enabling the functionalities of the patient portal.

The incorporation of patient portals within EHRs enhances patient engagement by promoting easier access to information and facilitating communication between patients and providers. This system not only improves the experience for patients but also helps healthcare providers manage patient care more efficiently.

Other systems mentioned, such as patient management systems and practice management software, may support certain administrative and billing functions but are not primarily designed to provide patients with direct access to their health records. Health Information Exchanges focus more on the sharing of data across different healthcare organizations rather than providing a direct patient interface. Therefore, EHRs are the most appropriate answer as they are directly linked to the functionalities provided through patient portals.
