Representation of Changes to Anesthesia Work Domain and Activity Structures

In this paper, we examine an approach to representing the impact of technological change on work practice. Taking Cognitive Work Analysis as a point of departure, we discuss an approach with which one can analyze work domains and work activities and then use these analyses as a ‘field’ upon which to trace the impact of new technology. The relation between activity and work structure is explored. Then, a case study of the introduction of an electronic anesthesia record is examined. Associated changes to work structures and activities are represented and interpreted. Finally, we discuss the implications of the work and future directions.
