The patient portal interface application communicates with a patient portal server to facilitate presentment of patient portal data to a user of the client EHR. The patient portal interface application provides a current context of the EHR to the patient portal server, and receives contextually-based patient portal data from the patient portal server. The contextual patient portal data is then displayed by way of a GUI of the patient portal interface application.
