[Health organizations from the perspective of complex care system]

The construction of new practices of care presupposes a new look for the health organizations. The objective of this text is to interpret the complexity theme in health and in Nurse fields in the care systems perspective, in order to promote a reflection of the practices of care in the health organizations context. The complex thought brings a new way to conceive the action and the human condition under different perspectives. It appears as a possibility for the visualization of a care system as a complex system in your structures and properties, in the movements of interretroactions in the organizational spaces and in possible auto-organizers processes. It is hoped a transforming action of the health organizations that considers the ambiguities, the uncertainties and the contemporary social dynamics for a healthier living.
