Introduction

National Taiwan University Hospital (NTUH) is a large scale healthcare centre and has been

operating over hundred years. Currently, it includes different generations of Healthcare

Information Systems (HIS); there are over 30 major independent systems in NTUH. These

systems consist of clinical information applications focusing on patient cares, pharmacy,

laboratory and radiology systems, administrative facilities, financial systems, resource

management, claims processing, etc. The portal is an essential entity to integrate, glue these

systems, platforms together. An effective, convenient as well as user friendly portal can

provide adequate information for NTUH staff, medical practitioners’ daily operations.

Moreover, a Single Sign on Service (SSOS) design is crucial to unify, simplify various

systems log-on processing.

As NTUH users’ requirements increase rapidly, the number of menu selections, i.e.,

applications or function linkages, grows exponentially. The scrollable extension menu,

implemented in the previous portal, is not spatial, temporal sufficiently and efficiently. The

maintainability of menu items is hampered under the situation. Furthermore, in general, a

user normally accesses not more than 10 function selections. In order to trace individual

behaviours for frequently executed functions, a logging scheme, containing a list of actions,

is proposed. Assistive web technologies for persons with disabilities are initiated. Therefore,

to improve the NTUH portal, we explore and launch a new one to achieve the targets.
