Only 53% of people hospitalised for self-harm get their mental health assessed


People hospitalised by self-harm are at higher risk of suicide - but less than half receive a mental health assessment afterward, a new study has revealed.

More than 84,000 cases over 12 years were looked at by the Multicentre Study of Self-harm in England, which found a "psychosocial assessment" by specialist staff occurred in 53.2% of them.

Guidelines issued by the National Institute for Health and Care Excellence in 2004 say assessments should be given in all cases.

Writing in the online journal BMJ Open, the team led by Professor Keith Hawton from the University of Oxford said people who "self-injured" were less likely, compared to those "self-poisoning" by taking overdoses, to receive a mental health assessment.

They wrote: "Our finding that only a little over half of individuals presenting to hospital after self-harm were offered psychosocial assessment and that individuals who self-injured were least likely to receive an assessment, coupled with the rise in self-injury as a method of self-harm and the link between such methods and suicide, may have important implications for the management of self-harm in hospitals.

"These include efforts to increase the overall rate of psychosocial assessment of patients who self-harm and, especially, to ensure that more of those who present with self-injury receive an assessment than appears to be current practice."

The paper also noted that while the "vast majority" of cases involved poisoning, "there is a stronger risk of suicide following self-cutting compared to self-poisoning".

The study, which involved Oxford, the University of Manchester and Derbyshire Healthcare NHS Foundation Trust, looked at 84,378 episodes of self-harm involving 47,048 people at five hospitals in Oxford, Manchester and Derby between 2000 and 2012.

Their definition of self-harm included "intentional injury and overdosing on prescription drugs".

It found that almost four out of 10 people (38%) were under 25, and nearly two thirds (62%) were under 35. Almost a third (30%) of the total patients were receiving some form of psychiatric care when they self-harmed.

Almost three quarters (74.6%) of self-harm admission to hospital were caused by an intentional overdose alone.

The researchers also found an increase in cases involving cutting and hanging or strangulation in the second half of the study period.

It concluded: "Trends in rates of self-harm and suicide may be closely related; therefore, self-harm can be a useful mental health indicator. Despite national guidance, many patients still do not receive psychosocial assessment, especially those who self-injure."
