The Street Clinic (CnaR) is a programme offered by the Unified Health System (SUS) and was approved in 2011 through the National Primary Care Policy (PNAB) with Ordinance 2. 488/11.

The aim of this study was to investigate the practices of the CnaR service from the perspective of the professionals who make up the team in the city of Aracaju, SE. In the field research, qualitative data was collected through semi-structured interviews with 6 professionals who made up the team.

The aim was to understand how the work of these teams has been carried out, especially from an interdisciplinary perspective; what challenges they face; and what the common demands of users are. As a result, it was possible to capture congruences between the professionals' statements, identifying core and field practices within the expanded clinic, with the formation of bonds between professionals and users, but challenges were also perceived in terms of articulation with the network and bureaucracy.

Based on this investigation, a critical reflection can be made within the country's public health system, comparing the theory of the documents that established the Unified Health System in Brazil with the practice in its status quo. .
