In recent decades, the definition of psychiatric emergencies (PEs) has changed. These differences derive from the radical reorganization of the treatment system, including psychiatric drugs, which in turn is closely connected with the shift of attention toward the patients’ environment and social inequalities, change of the psychiatric paradigm oriented toward a global management of the disorders, involvement of relatives and stakeholders and increasing awareness of the stigma of mental illness (even by professionals). Among the many differentiating factors of EPs, we must include the patients’ socioeconomic conditions, but also the different inequalities in the environment in which they live, including inequalities in access to care. EPs are also deeply related to the duration of untreated psychosis, whose average length in Western countries is 72 weeks. It seems essential to conduct a review of national legislations and deepen the debate on the medical, legal, and social concepts of dangerousness, in particular for compulsive admissions (CA) and to revise how to deal with these interventions often seen by patients as traumatic and useless. It is essential to keep in mind the warning on the overreliance in psychiatry and mental health education on the biomedical model which marginalizes social determinants.
