Abstract [en]

Work in intensive care units requires interaction with several medical devices and interpretation of dynamic information from several sources. The aim of the current study was to gain understanding of the work domain to support the development of a holistic information environment and further analyses of risky situations. A total of 18 hours of bed-side observations at an intensive care unit and interviews with three experienced intensive care unit nurses were conducted in order to receive input data for the modelling of the work domain. The domain was modelled in an abstraction hierarchy, as according to the first phase of the cognitive work analysis framework. The results show that the ultimate purpose of the work carried out in an intensive care unit is keeping patients alive while gaining time for treatment, but also to perform treatment and relieve symptoms. The purpose is represented at the top level of the model, and lower levels include functions as supporting the patients’ vital functions and avoiding secondary complications. With this work domain analysis as a basis, three different design challenges identified can be dealt with systematically.

Abstract [en]

The design of IT systems for complex work environments is essential for workers to be able to operate more effectively and efficiently. To design a system that supports the workers' specific tasks we need to understand the work demands and the context in which the system operates. However, this is a difficult task because of the dynamic nature of complex systems. The thesis investigates how the cognitive work analysis (CWA) framework (Vicente, 1999) can be applied to understand a domain under transformation by (1) developing methods to manage challenges associated with applying CWA to real-world complex systems and (2) investigating how models from the CWA framework can be used to contend with the moving target for development. The studies are carried out within two quite different application domains: long-haul driving and health care. An activity prioritization method was suggested as a useful technique to focus the analyzing efforts during the analysis of tasks and strategies. However, adaption to practical constraints has to be done thoughtfully in order not to lose the value of the analysis. Moreover, workshops were proposed as a means to bridge the gap between the analysis and design by finding design metaphors and possible future work strategies from the domain knowledge of the drivers. Third, a study was done using the abstraction hierarchy (AH) to learn about digitization in health care, which is an example of ongoing change in a work domain. The AH was also adapted to model health IT systems as a means to provide an overview and consistent vision of strategic decisions. Using the AH as an overview of sub-systems that were developed by different organizations or organizational units would make it possible to identify collaboration needs or a lack of connectivity and integration between systems. The AH can therefore be applied to support the development of an IT system that is to be part of a transforming work domain.
