[The analysis of a mobile mental health outreach team activity: from psychiatric emergencies on the street to practice of hospitalization at home for homeless people].

Context And Objective: Since their creation in 2005 in France, mobile mental health outreach teams (EMPP) have been working to improve the health of the homeless who, for 30 to 50% of them, present severe mental disorders. Their missions are defined by ministerial circular's specifications. Few studies have been undertaken in France to analyze the practices of these teams' professionals, nor the characteristics of the populations with whom they are involved.
