Nurses in the Kanban: are there news meanings of professional practice in innovative tools for hospital care management?

Kanban is a care management tool that values multi-professional work and intensive use of data and has been growingly used in Brazil to address overcrowding in hospital emergency services (HES). The researchers monitored the Kanban for ten months in multiple wards of a municipal HES, and their observations were recorded in field diaries and discussed in biweekly research team meetings. The empirical material was organized from two questions: Are there changes in "traditional attributions" of Kanban-operating nursing? Are Medicine-Nursing interprofessional relationships transformed? A strong nurse adherence to this tool was observed, coupled with greater specialization and fragmentation of their work: nurses working as diarists assume more traditional administrative functions, while those on-call develop more direct assistance to patients. Nurses consider that clinical decisions are still in the doctors' hands, although Kanban provides them with a stronger influence on such decisions. Nurses' role in the management of significant mass of clinical and operational data, central to Kanban's operationalization, strengthens their professional authority.
