[Operatory strategies and information management of nursing work in the hospital context]

The paper examines the relationship between operatory strategies and information process used by nurses, in hospital context, in order to regulate their ongoing activities. As a conceptual framework, a cognitive ergonomics model was adopted, linking concepts of work regulation and representation to action. The Ergonomics Work Analyses tool (EWA) was used to collect data. The results show that the cognitive strategies used by nurses, in the decision-making process, are based on their ongoing activities as in the preparation of personal notes, aiming, in particular, at reducing their mental workload and assuring the viability of their actions.
