ABSTRACT
Primary health care (PHC) in Brazil is based on Family Health Strategy (FHS) teams. These teams are supported by Expanded Family Health and Primary Care Centers (Nuclei) (NASF-AB) whose services are backbone elements for comprehensive health care within PHC. NASF-AB encompass several professional groups that aim to increase the responsiveness and scope of actions of the FHS teams. The objective of this study was to identify the dimensions of collaboration in the work dynamics of NASF-AB in the capital of Northeast Brazil. The study was a descriptive and exploratory research using a qualitative approach through semi-structured interviews with nine NASF-AB workers and three district health managers. Three analytical categories were identified following content analysis: "Interprofessional and inter-organizational collaboration," "Mainstays of collaboration in the relationship between NASF-AB and FHS," and "Challenges for a culture of collaboration in health care work." The results revealed important characteristics for interprofessional collaboration, including recognition of the attributions of the different teams and the key role of communication and planning. Participants highlighted roadblocks for interprofessional collaboration that hampered comprehensive care, such as the shortage of manpower and material resources, work overload, and lack of availability of professionals for effective teamwork.
