Classification of function linkages

In NTUH, the number of function linkages is numerous, over 300. Moreover, in the previous

portal, the links are not classified. It is not easy to scroll and select the target links. After

reviewing existing function links, we classify 7 groups and establish a hierarchical, dropdown

navigation menu as shown at top row of Figure 3. Each sub-tree or branch of the

hierarchical classification rooted at the portal represents a major subject area such as clinical

care, patient care, health services administration, research, and teaching. In here, the groups

are categorized into: HIS, Healthcare Supporting Services (HSS), Administrative

Information System (AIS), Digital Learning (DL), Information Security (IS), Personal Data

Management (PDM), and Other Resources (OR).

HIS and HSS involve most healthcare associated services. In HIS, it includes the major

healthcare information services, e.g., Registration, Ward, Laboratory, Pathology, Pharmacy,

and Billing. Medical Report Review Services, Critical Healthcare Alerts, and IC card tools

are classified in the HSS group. The AIS consists of Human Resources, Accounting, and

Medicine Inventory. The DL contains: educational instructions, discussion forums,

questionnaires, as well as on-line exams. Secured, classified documents and materials are

stored in IS. It provides privacy and security. Users’ personal information functions are

maintained in PDM group. These functions include personal password, e-mails, and control

access. Finally, the other administrative information is preserved in OR group, e.g.,

individual department home pages as well as announcements. Based on the classification,

the NTUH users can operate the portal intuitively and effectively.
