A study investigated and compared usability across eight different computerised critical care information systems (CCIS) currently used in Germany. German intensive care unit (ICU) nurses and physicians completed a specialised, previously validated, web-based questionnaire which assessed CCIS usability based on three rating models: an overall rating of the systems, a model rating technical usability, and a model rating task-specific usability. This is the first study to compare how clinical users rate the usability of CCIS currently in clinical use and to perform an in-depth analysis of the underlying conditions determining high/low CCIS usability. MetaVision was one of the three systems that received the highest marks in overall ratings as well as in ratings of technical usability (i.e., the ease-of-use or user-friendliness of the system), and task-specific usability (i.e., the utility of the system or functions/features that a program offers to support specific clinical tasks). The authors conclude that, “Regardless of the program used, our results show that the overall rating of a CCIS is more dependent on the program’s ease-of-use than the actual scope of the features that a program has to offer. Furthermore, for most systems, the general scope of the functions offered is rated better than how well the functions are realized. This suggests that the time has come for manufacturers to shift some of their effort away from the development of new features and focus increasingly on improving the user-friendliness and quality of existing features.”
