Bio-medical Ontologies Maintenance and Change Management

Design of an Online Physician-Mediated Personal Health Record System 275
treatment history is presumed to be stored in the hospital’s online EMR system.
We show a prototype implementation of the framework design in Oracle 10g database
at the backend and Apache/Tomcat web server at the frontend tomcat web
server using https protocol.
5.1 User Logons
This screen is designed as a secure access point to Personal Health Office online
system. The users of the system are patients and physicians (see Fig. 3). When
the user logs in as a patient, the user is authenticated by the authentication engine
and the appropriate menu is displayed based on the user access level.

5.2 EMR Access Request and Approvals
(a) (b)
The first time the patient Henry Wayne requests any EMR access, he needs to
identify his physician. In Fig. 4, we show that the patient may search physician
from the physician directory, and the Authorization Engine will retrieve a list of
primary physicians for the patient and displays to the patient. The patient then
selects pre-associated physician “Dr. Alexander Anthony” from the PHO system.
Once a selection of a physician is submitted, the patient can wait for the outcome
from his selected doctor.
There are two different user interfaces, one for the patient and the other for
the physician, that may be used to check/act on the status of patient EMR online
