In recent years, mental health policies have undergone significant changes, which have been reflected in a range of legislative, regulatory and institutional developments. They have also benefited from broader developments in health policies. In 2009, the creation of regional health agencies and health territories added two additional geographical dimensions to the psychiatric sectors, around which mental health care has been organised since the sixties. Maintained in their functional dimension, psychiatric sectors must now be linked to the regional level and health regions. The Law of 5 July 2011, as amended by the Law of 27 September 2013, also revamped the arrangements for treating patients receiving treatment without consent. In addition to full-time hospitalisation, compulsory care may be prescribed on a part-time or outpatient basis. This legislative reform also provides for the systematic intervention of a judge of freedoms and detention in order to strengthen the rights of persons treated without their consent. The definition and implementation of several ‘mental health plans’, the last of which covered the years 2011 to 2015, accompanied and encouraged professional and organisational changes in care and support. the Law of 26 January 2016 on the modernisation of our health system, through the ‘Territorial Public Health Service’, strengthens an organisation of mental health policy involving health, social and medico-social actors in the same area.
