The DUP is an easily measurable indicator, closely linked to prognosis and potentially modifiable, which has led to its wide use to guide the development of early identification programs. Great disparities exist across the world, between different countries and even different regions. France is unusually late, with an average DUP of at least 18 months. Several elements may contribute to explain this state in France: absence of a specific care program for FPE in the vast majority of psychiatric centers, significant stigmatization of psychiatric illnesses, the opacity of psychiatric care and of psychiatric care and lack of knowledge of its organization, in particular by the primary care network that receives patients with PEP in the first line. To date, there is no systematic program in France designed to rapidly identify FPE patients and hasten their specialized care. The objective of this study is to show the impact of an intervention facilitating access to specialized care for PEP on the reduction of DUP.
In addition, this study will seek to analyze the implementation factors of such an intervention in view of a possible generalization and perpetuation.
