The article presents a description and analysis of the implementation of a pre-hospital treatment system (SAMU) as part of the research project Diagnostic Analysis of the Implementation of a National Policy for the Reduction of Violence and Accidents. Implementation and organization of the SAMU service, together with the related materials, human resources, and equipment, was studied in five Brazilian State capitals with high morbidity and mortality rates from external causes: Curitiba (Paraná), Recife (Pernambuco), Brasília (Federal District), Rio de Janeiro, and Manaus (Amazonas). The study involved four phases, each developing exploratory and analytical cycles, combined with fieldwork, triangulating quantitative and qualitative data. Implementation of the pre-hospital treatment system is now a key health sector asset. Further necessary steps include: comprehensive legislation covering vehicles, personnel, and equipment; closer networking between mobile units and healthcare facilities; focus on information generated in this sub-system, thus facilitating planning; and maintaining and upgrading high qualifications for SAMU crews. The service is officially establishing, standardizing, and regulating a sub-system that is crucial for saving lives.
