Abstract
Objective: To identify the importance in NASF-AB as a support strategy, expansion and innovation of primary care, highlighting the main challenges and its multiprofessional network. Bibliographic review: With the Federal Government's position, based on the technical note, which concerns the end of the registration of new NASF-AB teams, which still gives the municipal and state managers the freedom to register health professionals in the National Registry of Health Establishments (CNES), we observed a huge loss in the scope of Health. Final considerations: The professionals who work at NASF-AB, have developed health actions such as home and outpatient activities, group activities, educational activities in teams. Corroborating with the importance of NASF-AB for full access to health, the literature is clear with regard to the impacts that the presence of NASF-AB professionals has on the quality of life of SUS users, in addition to developing actions in education in health and contribute to continuing health education.
