Self harm is a complex behaviour that can be best thought of as a maladaptive response to acute and chronic stress, often but not exclusively linked with thoughts of dying. Patients presenting with self harm usually have current psychosocial difficulties, are likely to be suffering from mental health problems, and are at significant risk of further self harm and suicide. Recent guidelines suggest that all self harm attendees should receive an initial risk assessment at triage in the emergency department. A more detailed mental health assessment and an assessment of psychological and social needs should then be performed by trained staff, ideally specialist mental professionals experienced in this area. Risk of subsequent suicide is particularly high in those with high unresolved suicidal intent, depressive disorder, chronic alcohol and drug misuse, social isolation, and current physical illness. Patients with one or more of these risk factors should be offered enhanced care that may include inpatient or outpatient follow up care, a list of local support resources, and, where possible, self help material. Frequent repeaters, those with alcohol and substance use problems, those with physical or mental illness, and those who are isolated also require input from specialist mental health professionals. It is also recommended that adolescents and elderly people warrant a mandatory specialist assessment.
