Knowledge and power necessary to reconstruct nursing after management changes at a teaching hospital.

This study was carried out at a teaching hospital in Southern Brazil, which adopted a management model that provoked the dismantling of the nursing service and the disbandment of nursing professionals. Its general goal was to promote changes that would be implemented in the re-organization of nursing work. It is a case study with a historical-dialectic approach, whose data were collected in March and April 2005 through the focal group technique. The study subjects were eight nurses, two technicians and two nursing auxiliaries. Data were analyzed through thematic content analysis. Results evidenced that the greatest challenges nursing faced at this hospital were: to construct a new identity, carry out teamwork while maintaining its professional identity, acquire visibility in the institution, change care and expand management.
