The Unified Health System (SUS) as a large technological system: territory, technique and politic

The Uni ed Health System (SUS) constitutes a large technological system wi- thin the Brazilian territory since it aggregates a broad and diverse materiality in organizing and managing its ows. Additionally, it has two other attributes that make it unique: high sensibility to speci cities of different places; and technical and political centralization and decentralization of its actions. The macro dimen- sion is the SUS, leading it to be understood not simply as a health system, through its: multidimensionality – elements of other life instances (social, economic, cul- tural and political); broad and unequal spectrum of actors (state and non-state) who move it and the meanings of its actions; and the trans-scaleness of its con- cretion in places (local, national and international nexuses). As an infrastructure of everyday life, it is a hegemonic large technological system that acts upon objec- tive (technosphere) and subjective (psychosphere) conditions of existence, a con- ception that has important implications for health policy and territory integration
