Cognitive evaluation: how to assess the usability of information technology in healthcare.
As the adoption of information technology has increased, so too has the demands that these systems become more adapted to the physicians and nurses environments, to make access and management of information easier. The developers of information systems in Healthcare must use quality management techniques to ensure that their product will satisfy given requirements. This underlines the importance of the preliminary phase where Users Requirements are elicited. Some methodologies, such as KAVAS (E.M.S. Van Gennip, F. Grémy, Med. Inform. 18, 1993, 179) chose to use a continuous assessment protocol as a key strategy for quality management. At each stage of the conception and development of a prototype, the assessment checks that it conforms to the expectation of the users' requirements. The methodology of evaluation is then seen as a dynamic process which is able to improve the design and development of a dedicated system. The purpose of this paper is to demonstrate the necessity to include a cognitive evaluation phase in the process of evaluation by: (1) evaluating the integration (usability) of the I.T. in the activity of the users; and (2) understanding the motives underlying their management of information. This will help the necessary integration of information management in the workload of the healthcare professionals and the compatibility of the prototypes with the daily activity of the users.
