them nervousness (2.10.2), discomfort (2.10.3) or anxiety (2.10.4,) even if they are
being obliged to use it (2.7.4 and 2.7.5). In the remaining issues in this group, the
average response is between 3 and 4 points.
Final it was possible to observe that some of the respondents have difficulties to
perform the information search in the system (2.2.1) because, despite the average
associated with this question be very close to 3 points, the mode of answers is 2
points. In addition, the relative average of responses to question 2.4.1 is less than 3
points, which points to some difficulty in solving the problems occurred in the
system, without need technical support.

4.3 Global Analysis

Table 5 presents a summary table of the average and mode responses obtained as a
function of each set of constructs in this model (TAM3). By observation of this table,
it appears that the respondents are generally satisfied with the AIDA system, because
the values obtained for the four constructs is bigger than 3 points.
The obtained value for the PU and PEOU construct, allow checking that the
respondents are aware that the system is useful in providing healthcare and increases
their performance in the organization. The perception of the usefulness of the system
combined with the fact of being easy to use it, boosts its acceptability and provides
voluntary intention to use it, as is possible to check with the values obtained for the
constructs BI and UB.

5 Conclusions

Completing the study of the application of TAM 3, the users of AIDA platform
showed to be satisfied with their performance in respect to the pathological exams
log. However, can be point out some features and system functionality with which
users show a degree of dissatisfaction, and that, consequently, decrease their intention
to use it. Despite the weakness found, users are aware of the practical utility of this
system and its importance in enhancing the quality of care and safety of the users.
This perception of users, is reflected in their behavioral intention to use it, as
supported by the applied model.
It is also possible to conclude that the benefits associated with the electronic exams
registration overlaps the apprehension felt by some users with regard to the use of
