Analysing the use of a computerized system by hospital managers

Case study, with a non-ex perimental design, conducted in a general hospital. The instrument used was based on the technological acceptance model. The population was composed of 63 managers and, based on the inclusion criteria, 60 managers were included in the study sample.

Results:

The system was considered useful by 90.5% of managers, while 84.7% agreed on its ease of use. The analyzed external variables (age, ease of using the technology, provision of training and technical support, computer availability, and favorability of use), showed an influence on satisfaction with the ease of use. The age and provided training did not influence satisfaction on the usefulness of the system.

Conclusion:

The managers showed greater satisfaction with the usefulness of the system when compared to the ease of use, due to the characteristics of the system and the institution.
