In order to adapt to the best Parisian proximity, territory and use device, the CHT is committed to understanding the populations served in terms demographic and epidemiological through the development of the mapping tool. The CHT thus equipped with a device of epidemiology in collaboration with Directorate of Social Action and the health of the city of Paris and the Atelier Parisien d'urbanisme.

The study of the Parisian socio-demographic determinants is an essential tool for the care to respond to the needs of the population served.

Work in epidemiology projects focus on three main themes:

  • The management of the crisis and the urgency in Psychiatry, and more particularly on the suicidal crisis
  • Characterization of hospitalized psychiatric patients
  • And the issue of care without consent.

The epidemiology of the CHT group is also working on the implementation of two major studies: one to characterise in terms demographic and clinical patients seen following an attempt of suicide in emergency services; the other concerned the decision criteria to support patients without their consent.

The density of doctors psy and use CHT card

Paris has, in 2014, 2610 psychiatrists. The density of psychiatrists is particularly low (less than 1 psychiatrist per 1,000) in the boroughs of the northern outskirts of the capital and especially in the 18th, 19th and 20th arrondissements, where it is less than 0, 5‰. Conversely, the 4th, 5th, 6th, 9th and 14th arrondissements are more than 2 psychiatrists per 1000 inhabitants.

The CHT institutions welcome near a Parisian on 40 (25.7 ). If the use of a facility of the CHT is less than 20 people per 1,000 in the 2nd and 16th arrondissements, it appears particularly high in the 13th (38.3 ‰) and 14th (36.1 ‰) arrondissements of Paris. The proximity of the ASM13 and the centre hospitalier Sainte-Anne could be a reason, as well as the large number of places of homes for people in precarious situations in the 13th arrondissement (3909 in 2011).
