ReviewPsychiatric disorders in patients presenting to hospital following self-harm: A systematic review
Section snippets
Background
Suicide and self-harm can result from a wide range of contributory factors (Hawton and Van Heeringen, 2009, Skegg, 2005). These include genetic, biological, childhood, psychological, psychiatric and social influences. The importance of psychiatric disorders in completed suicide has long been recognised (Barraclough et al., 1974, Harris and Barraclough, 1998) and been confirmed in many psychological autopsy studies (Cavanagh et al., 2003). On average, at least 90% of individuals dying by suicide
Method
We sought to identify all relevant studies of psychiatric disorders in individuals who had presented to general hospitals following an episode of self-harm. The latter included intentional self-poisoning or self-injury, irrespective of suicidal intent, and also attempted suicide and parasuicide. We included studies of individuals of all ages but aimed to report separately those of adults or mixed samples, those of adolescents and young people (up to age 25 years), and those of older persons
Included studies
The flow diagram for identification of studies for the review is shown in Fig. 1. We identified a total of 50 studies reported in 53 papers which met our inclusion criteria (Table 1). The studies were conducted in 24 countries. Seven of the studies were from the UK, five from India, four from the USA, three each from China, Hungary, Italy and Greece, two each from Denmark, Iran, Spain, Sweden, and Switzerland and one each from New Zealand, Australia, Hong Kong, Canada, Turkey, Finland, France,
Discussion
We have conducted a systematic review and meta-analyses of 50 studies conducted in 24 countries in which psychiatric disorders have been assessed in self-harm patients presenting to general hospitals.
Conclusions
Psychiatric disorders are found in over 80% of self-harm patients presenting to general hospitals, with depression, anxiety disorders and alcohol misuse being particularly common. This is similar to what has been found in people dying by suicide. Mental illness appears to be as prevalent in children and adolescents, in whom ADHD and conduct disorders are also quite common. Psychosocial assessment of self-harm patients should include careful screening for psychiatric disorder. In future, more
