Recent WHO guidelines emphasize on empowering communities to take ownership of their healthcare needs. Brazil’s UHS is a model for delivering community-based care through Family Health Strategy (FHS) interdisciplinary teams - ACS, nurses, and physicians. Our study compares nurses, physicians and ACS on their perceptions of work environment, professional skills, cognitive capacities and job context. Global health administrators and policy makers can leverage on comparisons across providers to develop interprofessional training and implement system-level interventions.
