[Healthcare professions: a critical analysis of care].

The article focuses on the activities of nurses and physical therapists within Brazil's Unified Health System (Sistema Único de Saúde), especially the Family Health Program. With the appearance of new professions and redefinitions in the practices of traditional healthcare professions, the subsequent multi-professional, interdisciplinary type of work has presented challenges when it comes to training new generations of healthcare providers, all part of an endeavor to humanize care and provide universalist, integrated, high-quality services. Collective health has contributed to this effort by networking with other fields of knowledge and human sciences. Healthcare fields have also sometimes tended to disregard any type of exchange with the human sciences, preferring to limit interactions to biomedical fields.
