How can usability measurement affect the re-engineering process of clinical software procedures?

Abstract

As a consequence of the dramatic improvements achieved in information technology standards in terms of single hardware and software components, efforts in the evaluation processes have been focused on the assessment of critical human factors, such as work-flow organisation, man-machine interaction and, in general, quality of use, or usability. This trend is particularly valid when applied to medical informatics, since the human component is the basis of the information processing system in health care context. With the aim to establish an action-research project on the evaluation and assessment of clinical software procedures which constitute an integrated hospital information system, the authors adopted this strategy and considered the measurement of perceived usability as one of the main goals of the project itself: the paper reports the results of this experience.
