Users' perceptions of a computerised information system in intensive care (ABICUS) on introduction and after 2 months use.

The aim of the present study was to assess the perceived utility of a computerised information system in an intensive care unit (ICU). Questionnaires were devised in which ICU staff indicated the ease or difficulty of obtaining and recording information (a) under the previous manual system, (b) soon after the introduction of the computerised system and (c) two months after computerisation. Results indicated the system was well received immediately and this favourable attitude persisted unchanged after two months experience. The questionnaire method also served to pinpoint some particular interface problems which are to be remedied in future versions of the system.
