[Technological change and work organization: usage producing competence. Case study of nursing records computerization in a cardiac surgical unit. Haut-Leveque Hospital, Bordeaux].
The computerisation of the nursing care file represents a technological change affecting the tools of the nursing processes. What is its incidence on the working procedures and the actors' knowledge? The computerised file appropriation comes within the scope of the instrumental genesis producing individual and collective skills. It requires the actors' ingenuity, mobilises their subjectivity, and implements co-operation dynamics which reconstruct the activity social dimension. The instrument considered here is a semiotic tool which mediatises the use of nursing methodological aids. It participates in the subject's action as a means of his action. How does the training then meet the demands of the people, the activity and its contexts? Between training logic and apprenticeship, the training proposed in a working situation becomes a training by work at the expense of people's contribution to the multiple collective regulations.
