[Networks for dialogue and coordination of health activities: a study on a regional mobile emergency care service].

Coordination of health services networks is one of the main challenges for health systems and requires an intricate web of interactions between service providers. This study assumes a model that uses communications networks as a central component of coordination and analyzes such networks in the Mobile Emergency Care Service (SAMU) in Greater Metropolitan Rio de Janeiro State Area II, Brazil. The study specifically seeks to analyze how verbal interactions influence this process. The research used direct observation and taping of meetings with data collection and analysis of conversation as the methodological strategy. The findings feature the identification of two main conversation networks as the mechanism for coordinating actions. The article highlights the importance of the concept of dialogical coordination as a tool for the analysis and improvement of coordination in health services systems.
