[The care team, from roots to new challenges].

The team is a fundamental and structuring dimension of care, founded on the principles of complementarity, interdependence, and shared objectives and responsibilities towards the patient. As a result of the pandemic and the rationalization of public hospitals, teams are faced with changes in the role of supervisors and the arrival of new figures such as advanced practice nurses. While these changes can bring new dynamism and questioning of practices, they can also be destabilizing. The institution must preserve the role of the team and its members.
