Preventing self-harm and suicide in prisoners: job half done

Prison populations have grown worldwide, and now exceed 10 million people globally. 1 Although some countries have clear and independent mechanisms of inspection, scant information is available about the conditions in which many prisoners are held. By necessity, published work in prisons represents a skewed sample of those countries from which evidence is made available. We must bear this discrepancy in mind because we know so little. What we do know is that prisoners have high levels of mental health morbidity. 2 Suicide is the prevailing cause of death in prison worldwide, with mortality rates more than three times higher than the general population. 3 The risk of death is highest in the early period after prison reception. 4 In male prisoners, deaths occur most typically in local adult prisons that take people directly from the courts, whereas self-harm happens widely in female prisons. 5 Mental disorder, substance misuse, white ethnic origin, violent off ending, awaiting trial, and having suicidal ideas are risk factors for death, many of which are common globally. 6 Although most risk factors for suicide are also prevalent in the general population, their frequency in prison is alarming. 2 Writing in The Lancet, Keith Hawton and colleagues 7 provide important confi rmation of risk factors for self-harm and suicide in prison. They did a 6-year epidemiological study in the prison population of England and Wales and recorded 139 195 self-harm incidents among 26 510 prisoners over 5 years. High annual self-harm rates were noted, in 5–6% of male inmates and 20–24% of female prisoners. Self-harm incidents accumulated in younger people and those of white ethnic origin, and an association was noted with prison type, serving a life sentence, or being unsentenced. Violent off ending behaviour raised the risk of self-harm in female prisoners, and recurrence was common. The reported clustering of self-harm in time and location (adjusted intra-class correlation 0·15, 95% CI 0·11–0·18) highlights the importance of the priso n context in understanding self-harm.

Hawton and colleagues showed a temporal link between self-harm and completed suicide; 109 suicides in prison were reported in individuals who self-harmed, and more than half the deaths occurred within a month of self-harm.These fi ndings indicate the importance of swift intervention after an incident of self-harm, and this work has already had an eff ect on the way the Prison Service in England and Wales manages people at risk. 8The risk factors identifi ed for self-harm are similar to those identifi ed elsewhere for suicide, thereby challenging the notion that self-harming behaviour and suicide might represent diff erent entities: instead, a direct link seems to exist for many prisoners.Hawton and colleagues make a vital contribution to answering the questions of who self-harms and how often does it happen, which complements previous work to address why people self-harm and what methods work to reduce self-harm and suicidal behaviour. 9,10However, additional work is now needed to address these questions, to reduce self-harm in prison further. 5lthough this work by Hawton and colleagues will assist practice in prisons in England and Wales, a broad range of risk factors have been incorporated into assessment training and processes provided by the Prison Service for some years. 8To mitigate against diminishing returns through expansion, we need to understand why most prisoners do not self-harm and why some who harm themselves are propelled towards suicide whereas others are not.The answers to these questions do not necessarily sit with further examination of over-represented groups, but instead could be studied by focusing on process, 3 including specifi c investigation of prisoners from groups with enhanced vulnerabilities-eg, inmates who are foreign nationals, or people with neurodevelopmental problems, including those with learning diffi culties.For many individuals, including 102 female prisoners reported by Hawton and colleagues who accounted for around 17 000 self-harming incidents, an examination that goes beyond generalised risk factors is crucial.
In England and Wales, a welcome and sustained reduc tion in the overall number of self-infl icted prison deaths has been noted, from 96 in 2004 to 60 in 2012. 4his fall has happened after several initiatives were introduced, including safer custody measures through the ACCT (Assessment, Care in Custody, and Teamwork) process, 8 enhanced mental health services, and piece meal environmental improvements.Although dis entangling specifi c causal factors can be diffi cult from a pure research perspective, in view of confounders, the evaluative focus of the Independent Advisory Panel on Deaths in Custody allows cautious optimism.With attention now turning to self-harm management, avail able evidence indicates a key role for multi-agency collaboration, in which "suicide is everyone's concern", 11 rather than being the sole preserve of health-care staff .As such, collaboration between organisations-with responsibility held jointlycould be an important preventive measure, for both selfharm and suicide.Prison offi cers can provide practical support, which could calm distress and play a central part in identifi cation and management of risk, and have a key role in recognition of undetected psychiatric morbidity. 12To harness this potential and thereby avoid so-called silo working, a focus on eff ective joint systems and a widening of the scope of specialist training and supervision (currently only available to a few prison workers in the UK) is recommended.
Despite clear gains in the care of prisoners and prevention of self-harm and suicide in prisons in England and Wales, much work remains to be done.Linking epidemiological samples and ground-level improve ments is not easy.A renewed approach is needed that seeks to understand better the connection between suicidal ideation and completed suicide.We need to invest in the wide inclusion of all people who, on the ground, can listen to prisoners who are experiencing distress, mobilise concern, and help to deliver joined-up care.
