Discovering how to think about a hospital patient information system by struggling to evaluate it: a committee's...

Parallel to the monumental problem of replacing paper-and-pen-based patient information management systems with electronic ones is the problem of evaluating the extent to which the change represents an improvement. All clinicians must grapple with this daunting challenge; those with little or no informatics expertise may be particularly surprised by the attendant difficulties. To do so successfully, they must be able to explicitly conceptualize the daily clinical work-a prerequisite for appreciating and reasonably evaluating it. Further, few of these evaluators may have reflected on the dynamic interaction between their work and their tools-how changing a tool necessarily changes the work. This article illuminates these problems by telling the story of how one patient care information systems committee first learned to think about the purpose of a patient information management system, and second, how to evaluate the impact of its implementation.
