such failure, such as costs, resistance to change, fear or attempt to avoid technology.
However, increasingly, their low level of usability has been recognized as the
fundamental element for the adoption of information systems in hospitals. In this way, it
is essential to take measures to ensure that the information systems and their interfaces
are designed in a simple and interactive way, making them easily usable and accepted
working practices of health professionals. After their implementation, usability
assessments are fundamental in order to increase the satisfaction of its users, and
therefore their acceptance and willingness to use them [4, 5]. In order to assess the
technology of electronic registration exams in Pathologic Anatomy Service of Centro
Hospitalar Alto Ave (CHAA), the most recent version of Technology Acceptance
Model (TAM3) was adopted. This paper is divided in six sections and presents a brief
overview of the context, the work made and the main achieved results.

Background
2.1
AIDA
Information systems have great potential for integration and automation of information.
However, healthcare organizations are represented computationally by a set of
heterogeneous systems, distributed and ubiquitous that use different languages, integrate
different medical equipment and are customized for different entities with different
purposes. Thus, communication between the systems is difficult to obtain. The solution
is to integrate, disseminate and archive all information in a dynamic structure that
enables the sharing of information with all information systems. To this end, it was
developed AIDA platform [6][7]. AIDA provides a set of electronic intelligent agents,
called proactive agents, responsible for the execution of tasks such as communication
between heterogeneous systems, sending and receiving information (e.g. medical and
clinical reports, images, data set and prescriptions), storage and information
management, and response to requests, through the use of features that allow its correct
performance in real time. As a way of facilitating access to information and means of
communication, AIDA also supports web services. AIDA takes a central role in
Hospital Management System (HMS), ensuring not only the archive of medical
information but also communication between different subsystems, namely [6,7,8]:
Administrative Information System (AIS); The Medical Support Information System
(MIS); The Nursing Support Information System (NIS); The Information Systems (DIS)
and Radiological information systems and medical imaging (PACS).

Electronic Register of Reports of Medical Examinations in CHAA
The AIDA platform is already in CHAA and allows the electronic registration of
exams. When a physician requests a laboratory examination it is scheduled in
management platform (SONHO), by the corresponding administrative service.
Subsequently, the AIDA platform access to the scheduling information and starts all
the electronic registration process made request. This process is divided into three
distinct phases: reception, register and report. At the reception stage it is possible to
carry out an exam by different research fields (type of task, process number, episode
