Intimate Partner Violence Victimization, Mental Health, and Unemployment: Year One of the Covid-19 Pandemic.

We assessed the impact of mental health and participant and partner unemployment on physical, sexual, and psychological intimate partner violence (IPV). Data were collected within 1 month of individual state Covid-19 mandates (Time I) and 2 months after mandates eased (Time II). Sexual IPV was highest when both partners were unemployed for reasons other than Covid-19 while physical IPV was highest when both partners were unemployed due to Covid-19. Physical IPV victims reported more depression and somatization at Time II than at Time I. Nonvictims did not. There were no differences in IPV prevalence during and after restrictions. Clinical and policy implications are discussed.

Self-harm in university students: A comparative analysis of data from the Multicentre Study of Self-harm in England.

BACKGROUND: Increases in poor mental health and suicide have been identified among university students in the UK. However, little is known about self-harm in this group. AIMS: To describe and identify care needs of university aged-students who self-harm via comparisons with an age-equivalent non-student group who self-harm. METHODS: Observational cohort data from The Multicentre Study of Self-harm in England were used to investigate students aged 18 to 24 years who presented to emergency departments for self-harm, 2003 to 2016. Data were collected via clinician reports and medical records from five hospitals in three English regions. Characteristics, rates, repetition, and mortality outcomes were investigated. RESULTS: The student sample included 3491 individuals (983, 28.2 % men; 2507, 71.8 % women; 1 unknown) compared to 7807 (3342, 42.8 % men; 4465, 57.2 % women) non-students. Self-harm increased over time in students (IRR 1.08, 95%CI 1.06-1.10, p < 0.01) but not in non-students (IRR 1.01, 95%CI 1.00-1.02, p = 0.15). There were differences in monthly distribution of self-harm with more presentations by students in October, November, and February. Characteristics were broadly similar, but students reported more problems with studying and mental health. Repetition (HR 0.78, 95%CI 0.71-0.86, p < 0.01) and mortality (HR 0.51, 95%CI 0.33-0.80, p < 0.01) were lower in students than non-students. CONCLUSIONS: Self-harm in students may be directly related the student experience, such as academic pressure, relocation, and the transition to independent living. Wellbeing initiatives targeting these factors, alongside mental health awareness training for academic and non-academic staff may help to support students at risk.

The characteristics, life problems and clinical management of older adults who self-harm: Findings from the multicentre study of self-harm in England.

BACKGROUND: Older adults have a high risk of suicide following self-harm. Contemporary information on self-harm in this population is needed to inform care provision. OBJECTIVES: To examine subgroup differences in the incidence of self-harm, sociodemographic and clinical characteristics, preceding life problems and outcomes in individuals aged 60 years and over presenting to hospital following self-harm. METHOD: Data on Emergency Department (ED) presentations for self-harm from 2003 to 2016 from three centres in the Multicentre Study of Self-Harm in England were analysed. Changes in self-harm rates were examined using Poisson regression. Univariable logistic regression was used to investigate factors associated with 12-month self-harm repetition. RESULTS: There were 3850 presentations for self-harm by 2684 individuals aged 60 years and over. Self-harm rates increased over time for 60-74-year-old men (Incident Rate Ratio = 1.04, 95% Confidence Interval 1.02-1.06, p < 0.0001). Problems most frequently reported to have preceded self-harm were mental health (40.5%) and physical health (38.3%) concerns. Problems with alcohol, finances, employment and relationship with partner were found more frequently in 60-74-year-olds compared with those aged over 74 years. Physical health problems were common with increasing age, as were problems with alcohol for men. One in ten (10.8%) individuals presented to hospital with self-harm within 12 months of their index presentation. CONCLUSIONS: Self-harm-related ED attendances in older men have increased, particularly for men aged 60-74 years. Prevention and clinical management should involve a comprehensive psychosocial assessment to target common precipitants for the wide range of problems preceding self-harm and may include support with physical and mental wellbeing and advice on safer alcohol use.

Risk of suicide in patients who present to hospital after self-cutting according to site of injury: findings from the Multicentre Study of Self-harm in England.

BACKGROUND: We compared the risk of death by suicide following hospital presentation for self-harm according to site of self-cut/stab. METHOD: We included 54 999 self-harm presentations (involving 31 419 individuals) to hospitals in the Multicentre Study of Self-harm in England (1/1/2004-31/12/2014), with mortality follow-up to 31/12/2019. Information on method of self-harm was obtained through monitoring in hospitals. Information about mortality was obtained through linkage with NHS Digital. We assessed the association of site of self-cut with death by suicide using mixed effect models. RESULTS: In total, 10 790 (19.6%) hospital presentations involved self-cutting/stabbing, 7489 of which (69.4%) were due to laceration to the arm/wrist alone, 1846 episodes (17.1%) involved cutting elsewhere on the body, and 1455 (13.5%) were due to laceration to unknown site. Controlling for confounders, presentation to a hospital following self-cut/stab to bodily parts other than wrist/arm was associated with greater chance of subsequent suicide relative to presentation after self-poisoning alone [adjusted odds ratio (aOR) 1.75, 95% confidence interval (CI) 1.03-2.96, p = 0.038]. The likelihood of suicide after presentation for cutting/stabbing the wrist/arm alone was comparable to that of patients who had self-poisoned alone. Presentations after laceration involving the neck were associated with a four-fold greater chance of subsequent suicide relative to self-poisoning (aOR 4.09, 95% CI 1.80-9.30, p = 0.001). CONCLUSIONS: Patients who attend hospital after self-cutting/stabbing are a heterogeneous group in terms of characteristics, methods of cutting/stabbing and risk of subsequent suicide. Risk of suicide is greater in individuals who self-cut/stab to parts of the body other than the wrist or arm, especially the neck.

Socio-economic disparities in patients who present to hospital for self-harm: patients' characteristics and problems in the Multicentre Study of Self-harm in England.

BACKGROUND: We examined disparities in sociodemographic and clinical characteristics and in problems preceding self-harm across levels of socio-economic deprivation (SED) in persons who presented to hospital for self-harm. METHOD: 108,092 presentations to hospitals (by 57,306 individuals) following self-harm in the Multicentre Study of Self-harm in England (1/1/2000-31/12/2016). Information on area-level SED was based on the English Index of Multiple Deprivation. Information about patients' characteristics and problems was obtained from self-harm monitoring systems in the hospitals. We assessed the association of SED with the characteristics of interest using descriptive statistics. RESULTS: Overall, 45 % of the presentations were by individuals from areas ranked nationally as most deprived, while 13 % of episodes were by individuals from the least deprived areas. Males and non-white ethnic groups were over-represented in the most deprived SED stratum. Previous self-harm was more prevalent in the two most deprived groups. Relationships difficulties with partners and other family members were reported more commonly by individuals from less socio-economically deprived areas, as were problems pertaining to finances and employment or studies. Problems in relationships with friends were more prevalent in the most deprived group relative to other groups. LIMITATIONS: Information about problems which preceded self-harm was available only for patients who received psychosocial assessment. CONCLUSIONS: Patients vary considerably across area-level SED strata in terms of gender, ethnicity, and the problems which preceded their self-harm. These findings emphasise the need to use an individualised approach to patients in understanding the unique circumstances which contribute to their self-harm and their specific care needs.

Self-harm in people experiencing homelessness: investigation of incidence, characteristics and outcomes using data from the Multicentre Study of Self-Harm in England.

BACKGROUND: People who experience homelessness are thought to be at high risk of suicide, but little is known about self-harm in this population. AIMS: To examine characteristics and outcomes in people experiencing homelessness who presented to hospital following self-harm. METHOD: Data were collected via specialist assessments and/or hospital patient records from emergency departments in Manchester, Oxford and Derby, UK. Data were collected from 1 January 2000 to 31 December 2016, with mortality follow-up via data linkage with NHS Digital to 31 December 2019. Trend tests estimated change in self-harm over time; descriptive statistics described characteristics associated with self-harm. Twelve-month repetition and long-term mortality were analysed using Cox proportional hazards models and controlled for age and gender. RESULTS: There were 4841 self-harm presentations by 3270 people identified as homeless during the study period. Presentations increased after 2010 (IRR = 1.09, 95% CI 1.04-1.14, P < 0.001). People who experienced homelessness were more often men, White, aged under 54 years, with a history of previous self-harm and contact with psychiatric services. Risk of repetition was higher than in domiciled people (HR = 2.05, 95% CI 1.94-2.17, P < 0.001), as were all-cause mortality (HR = 1.45, 95% CI 1.32-1.59. P < 0.001) and mortality due to accidental causes (HR = 2.93, 95% CI 2.41-3.57, P < 0.001). CONCLUSIONS: People who self-harm and experience homelessness have more complex needs and worse outcomes than those who are domiciled. Emergency department contact presents an opportunity to engage people experiencing homelessness with mental health, drug and alcohol, medical and housing services, as well as other sources of support.

Cost-effectiveness of psychosocial assessment for individuals who present to hospital following self-harm in England: A model-based retrospective analysis.

BACKGROUND: Guidance in England recommends psychosocial assessment when presenting to hospital following self-harm but adherence is variable. There is some evidence suggesting that psychosocial assessment is associated with lower risk of subsequent presentation to hospital for self-harm, but the potential cost-effectiveness of psychosocial assessment for hospital-presenting self-harm is unknown. METHODS: A three-state four-cycle Markov model was used to assess cost-effectiveness of psychosocial assessment after self-harm compared with no assessment over 2 years. Data on risk of subsequent self-harm and hospital costs of treating self-harm were drawn from the Multicentre Study of Self-Harm in England, while estimates of effectiveness of psychosocial assessment on risk of self-harm, quality of life, and other costs were drawn from literature. Incremental cost-effectiveness ratios (ICERs) for cost per Quality Adjusted Life Year (QALY) gained were estimated. Parameter uncertainty was addressed in univariate and probabilistic sensitivity analyses. RESULTS: Cost per QALY gained from psychosocial assessment was £10,962 (95% uncertainty interval [UI] £15,538-£9,219) from the National Health Service (NHS) perspective and £9,980 (95% UI £14,538-£6,938) from the societal perspective. Results were generally robust to changes in model assumptions. The probability of the ICER being below £20,000 per QALY gained was 78%, rising to 91% with a £30,000 threshold. CONCLUSIONS: Psychosocial assessment as implemented in the English NHS is likely to be cost-effective. This evidence could support adherence to NICE guidelines. However, further evidence is needed about the precise impacts of psychosocial assessment on self-harm repetition and costs to individuals and their families beyond immediate hospital stay.

Life problems in children and adolescents who self-harm: findings from the multicentre study of self-harm in England.

BACKGROUND: Self-harm, a significant and increasing global problem in children and adolescents, is often repeated and is associated with risk of future suicide. To identify potential interventions, we need to understand the life problems faced by children and adolescents, and by sub-groups of younger people who self-harm. Our aims were to include the following: (a) investigate the type and frequency of life problems in a large sample of children and adolescents who self-harmed. (b) Examine whether problems differ between those who repeat self-harm and those who do not. METHODS: We analysed data for 2000 to 2013 (follow up until 2014) from the Multicentre Study of Self-harm in England on individuals aged 11 to 18 years who presented to one of the five study hospitals following self-harm and received a psychosocial assessment including questions about problems, which precipitated self-harm. RESULTS: In 5648 patients (12,261 self-harm episodes), (75.5% female, mean age 16.1 years) the most frequently reported problems at first episode of self-harm were family problems. Problems around study/employment/study and relationships with friends also featured prominently. The types of problems that precede self-harm differed between late childhood/early adolescence. Abuse, mental health problems and legal problems significantly predicted repeat self-harm for females. CONCLUSION: The most common problems reported by both genders were social/interpersonal in nature, indicating the need for relevant services embedded in the community (e.g. in schools/colleges). Self-harm assessment and treatment choices for children and adolescents must take age and gender into account. To prevent future self-harm, individualised supports and services are particularly needed for abuse, mental health and legal problems.

Identifying Suicide and Self-Harm Research Priorities in North West England.

Background: Understanding and effectively managing self-harm and suicide require collaborative research between stakeholders focused on shared priorities. Aims: We aimed to develop a consensus about suicide and self-harm research priorities in the North West of England using the Delphi method. Method: Items for the Delphi survey were generated through group discussions at a workshop with 88 stakeholders and subsequent thematic analysis of key themes. A total of 44 participants who were experts-by-experience, researchers, and clinicians based within health services including third-sector organizations completed the Delphi survey. Results: A three-round survey reached consensus on 55 research priority items identifying key priorities in each of the following groups: offenders, children and young people, self-harm in community settings, and crisis care in the community. Limitations: The pool of delegates at the workshop and subsequent self-selection into the Delphi may have introduced bias into the study. Conclusion: The current paper highlights specific actionable priorities were identified in four areas that can be used to inform research efforts and future policy and practice, based on shared areas of perceived importance and concern. Future work is needed to confirm the significance of these priority areas, including the use of evidence synthesis approaches to ascertain the extent to which these priorities have already been investigated and where gaps in understanding remain.

Self-harm in children 12 years and younger: characteristics and outcomes based on the Multicentre Study of Self-harm in England.

BACKGROUND: Very little is known about self-harm in children. We describe the characteristics and outcomes of children under 13 years who presented following self-harm to five hospitals in England. METHODS: We included children under 13 years who presented after self-harm to hospitals in the Multicentre Study of Self-harm in England. Information on patients' characteristics and method of self-harm was available through monitoring of self-harm in the hospitals. Area level of socioeconomic deprivation was based on the English Index of Multiple Deprivation (IMD). RESULTS: 387 children aged 5-12 years presented to the study hospitals in 2000-2016, 39% of whom were 5-11 years. Boys outnumbered girls 2:1 at 5-10 years. The numbers of boys and girls were similar at age 11, while at 12 years there were 3.8 girls to every boy. The proportion of study children living in neighbourhoods ranked most deprived (43.4%) was twice the national average. 61.5% of children self-poisoned, 50.6% of them by ingesting analgesics. Of children who self-injured, 45.0% self-cut/stabbed, while 28.9% used hanging/asphyxiation. 32% of the children had a repeat hospital presentation for self-harm, 13.5% re-presented within a year. CONCLUSIONS: Gender patterns of self-harm until age 11 years are different to those of adolescents, with a male preponderance, especially in 5-10 years, and hanging/suffocation being more common. The frequent use of self-poisoning in this age group highlights the need for public health messages to encourage safer household storage of medicines. Self-harm in children is strongly associated with socioeconomic deprivation; understanding the mechanisms involved could be important in effective prevention.

Victim and Perpetrator Acknowledgement of Intimate Partner Violence and Victim Psychopathology.

The present study assesses differences between acknowledged and unacknowledged victims in post-victimization psychopathology, abuse disability and coping. Few studies have examined abuse acknowledgment among intimate partner violence (IPV) victims. To our knowledge, this study is the first to use an experimental manipulation to assess changes in acknowledgment among IPV victims. Female undergraduate students currently in dating relationships completed demographic, coping and psychopathology questionnaires, and the Conflict Tactics Scale (CTS). They then watched a video of an IPV perpetrator who either acknowledged abuse or did not acknowledge abuse. Following the video, participants completed a psychopathology questionnaire and a post-video acknowledgment assessment. Approximately 38% of the sample reported IPV victimization. Only 7.89% acknowledged victimization. Acknowledged IPV victims had the highest mean victimization score but reported psychopathology similar to nonvictims on all subscales except phobic anxiety. Unacknowledged victims reported greater psychopathology, depression, anxiety, and hostility than nonvictims and were more symptomatic overall. Unacknowledged victims reported more frequent use of avoidant coping strategies than nonvictims. These strategies included substance use, self-blame, and behavioral disengagement. Acknowledged and unacknowledged victims reported greater abuse disability than nonvictims, and acknowledged victims reported greater life restriction than unacknowledged victims. Following the video, the number of acknowledged victims nearly doubled, and acknowledged victims reported increased depression. On the basis of these findings, clinicians and researchers should carefully consider acknowledgment as a potential factor in post-victimization mental health and explore ways to increases victim acknowledgment.

Self-harm in children and adolescents by ethnic group: an observational cohort study from the Multicentre Study of Self-Harm in England.

BACKGROUND: Studies report an increasing incidence of self-harm in children and adolescents, but the extent to which this is seen in different ethnic groups is unclear. We aimed to investigate rates of emergency department presentations for self-harm in children and adolescents by ethnicity, as well as to examine their demographic characteristics, clinical characteristics, and outcomes. METHODS: In this observational cohort study, we used data on hospital emergency department presentations for self-harm in children and adolescents aged 10-19 years between 2000 and 2016 from the Multicentre Study of Self-harm in England. This study collects data from five general hospitals in Manchester, Oxford, and Derby in the UK, and defines self-harm as any act of intentional self-injury or self-poisoning, regardless of intent. All children and adolescents aged 10-19 years for whom ethnicity data were available were included. Mortality follow-up was available through linkage with mortality records from the Office for National Statistics. Rates of self-harm over time, demographic and clinical characteristics, and self-harm methods were investigated by ethnic group. Risk of repeat self-harm and mortality following an initial presentation for self-harm was compared by ethnic group using Kaplan-Meier curves and Cox proportional hazards models. FINDINGS: Of 14 894 individuals who presented at hospitals with self-harm, 11 906 had data for ethnicity, of whom 10 211 (85·8%) were White, 344 (2·9%) were Black, 619 (5·2%) were South Asian, and 732 (6·1%) were other non-White. Rates of self-harm were highest in White children and adolescents but increased between 2009 and 2016 in all ethnicities. Mean annual rates of self-harm per 100 000 population were 574 for White, 225 for Black, 260 for South Asian, and 344 for other non-White groups. Increases in rates of self-harm between 2009 and 2016 appeared slightly greater in Black groups (incidence rate ratio 1·07 [95% CI 1·03-1·11]), South Asian groups (1·05 [1·01-1·09]), and other non-White groups (1·11 [1·06-1·16]) than in White groups (1·02 [1·00-1·03]). Children and adolescents from a minority ethnic background were more likely to live in areas of high deprivation and were less likely to receive a specialist psychosocial assessment than were White children and adolescents. Children and adolescents from minority ethnic groups were also less likely to repeat self-harm. However, there were no differences in suicide mortality by ethnic group, although the numbers were small. INTERPRETATION: Minority ethnic children and adolescents accounted for an increased proportion of self-harm presentations to hospital over time compared with White ethnic groups. The minority ethnic groups also tended to be more socioeconomically disadvantaged and were less likely to receive a psychosocial assessment. Socioeconomic disparities need to be addressed, and equitable access to culturally sensitive comprehensive psychosocial assessments must be ensured. FUNDING: UK Department of Health and Social Care.

Community Outpatient Psychotherapy Engagement Service for Self-harm (COPESS): a feasibility trial protocol.

BACKGROUND: People who self-harm are at high risk for future suicide and often suffer considerable emotional distress. Depression is common among people who self-harm and may be an underlying driver of self-harm behaviour. Self-harm is often repeated, and risk of repetition is highest immediately after an act of self-harm. Readily accessible brief talking therapies show promise in helping people who self-harm, but further evaluation of these approaches is needed. A brief talking therapy intervention for depression and self-harm has been designed for use in a community setting. This mixed methods feasibility study with repeated measures will examine the feasibility and acceptability of the Community Outpatient Psychological Engagement Service for Self-Harm (COPESS) for people with self-harm and depression in the community, compared to routine care. METHODS: Sixty participants with a history of self-harm within the last six months, who are also currently depressed, will be recruited to take part in a feasibility single-blind randomised controlled trial (RCT). Participants will be randomised 1:1 to receive COPESS plus treatment as usual (TAU) or TAU alone. Recruitment will be via General Practitioners (GP) and self-referral. Assessment of feasibility and acceptability will be assessed via quantitative and qualitative methods including measures of recruitment and retention to the feasibility trial, participants' experience of therapy, completion/completeness of outcome measures at relevant time-points and completion of a service use questionnaire. DISCUSSION: The results will indicate whether it is feasible to conduct a definitive full trial to determine whether COPESS is a clinically and cost effective intervention for people who self-harm in the community. Qualitative and quantitative data will in addition help identify potential strengths and/or challenges of implementing brief community-based interventions for people who self-harm. TRIAL REGISTRATION: NCT04191122 registered 9th December 2019.

Threat Bias and Emotion Recognition in Victims of IPV.

Although there is growing evidence of the association between threat bias and psychopathology in many trauma-exposed populations, there are few studies with intimate partner violence (IPV) victims. The present study assessed threat bias in IPV victims. It also examined potential differences in facial recognition ability between victims and nonvictims. Participants were 153 female college students currently in a dating relationship. Participants completed demographic and abuse severity measures. They then completed a dot-probe task to assess threat bias, and a facial expression recognition task to assess speed and accuracy of recognition. Approximately 32% of the students sampled were currently in a physically abusive relationship. Results indicated that IPV victims had a bias toward fearful faces, and showed worse recognition of happy faces than nonvictims. These data suggest that the psychological impact of threat bias might vary temporally. Vigilance during threat may serve as a protective mechanism, whereas postthreat vigilance might be associated with psychopathology. Researchers should carefully consider the presence of threat bias in victim samples and include other victim groups in future assessments of threat bias. It will be important to test these relationships in other IPV victim samples, such as help-seeking victims and other community living victims.

Paracetamol self-poisoning: Epidemiological study of trends and patient characteristics from the multicentre study of self-harm in England.

BACKGROUND: Paracetamol is frequently used for intentional self-poisoning, especially in the UK, despite pack size restrictions introduced in 1998. Knowing more about paracetamol self-poisoning may identify further approaches to prevention. METHODS: We used data from the Multicentre Study of Self-harm in England for 2004-2014 to calculate incidence rates of presentations to Emergency Departments following self-poisoning with pure paracetamol alone. National estimates for England for 2011-2014 were extrapolated using indirect age-standardised rates. The characteristics of individuals taking paracetamol overdoses and the size of the overdoses were investigated. RESULTS: A third of 54,863 intentional overdoses presenting to the five Emergency Departments involved paracetamol without other drugs (N = 18,011), taken by 13,171 individuals (63.4% female).  The proportion of paracetamol self-poisonings was similar in the three centres. Extrapolation suggested there were approximately 50,000 paracetamol overdoses in England annually during 2011-2014. Females had higher rates of paracetamol overdose than males.  Males and older individuals took larger overdoses.  Nearly a quarter of individuals (24.2%) consumed more than 32 tablets. Alcohol was involved in 53.7% of paracetamol overdoses. LIMITATIONS: Data were collected in three centres with predominantly urban populations. Extrapolation from local to national rates should be interpreted with caution. CONCLUSIONS: Paracetamol overdose remains a major problem in the UK. It is more common in females and younger patients, but males and older patients consume larger overdoses. Consideration should be given to further restriction in pack sizes and sources of sales, in keeping with those of several other European countries.

Incidence and general hospital costs of self-harm across England: estimates based on the multicentre study of self-harm.

AIMS: The aim of this study was to estimate incidence of self-harm presentations to hospitals and their associated hospital costs across England. METHODS: We used individual patient data from the Multicentre Study of Self-harm in England of all self-harm presentations to the emergency departments of five general hospitals in Oxford, Manchester and Derby in 2013. We also obtained cost data for each self-harm presentation from the hospitals in Oxford and Derby, as well as population and geographical estimates from the Office for National Statistics. First, we estimated the rate of self-harm presentations by age and gender in the Multicentre Study and multiplied this with the respective populations to estimate the number of self-harm presentations by age and gender for each local Clinical Commissioning Group (CCG) area in England. Second, we performed a regression analysis on the cost data from Oxford and Derby to predict the hospital costs of self-harm in Manchester by age, gender, receipt of psychosocial assessment, hospital admission and type of self-harm. Third, the mean hospital cost per age year and gender were combined with the respective number of self-harm presentations to estimate the total hospital costs for each CCG in England. Sensitivity analysis was performed to address uncertainty in the results due to the extrapolation of self-harm incidence and cost from the Multicentre Study to England. RESULTS: There were 228 075 estimated self-harm presentations (61% were female) by 159 857 patients in 2013 in England. The largest proportions of self-harm presentations were in the age group 40-49 years (30%) for men and 19-29 years (28%) for women. Associated hospital costs were approximately £128.6 (95% CI 117.8-140.9) million in 2013. The estimated incidence of self-harm and associated hospital costs were lower in the majority of English coastal areas compared to inland regions but the highest costs were in Greater London. Costs were also higher in more socio-economically deprived areas of the country compared with areas that are more affluent. The sensitivity analyses provided similar results. CONCLUSIONS: The results of this study highlight the extent, hospital costs and distribution of self-harm presentations to hospitals in England and identify potential sub-populations that might benefit from targeted actions to help prevent self-harm and assist those who have self-harmed. They can support national as well as local health stakeholders in allocating funds and prioritising interventions in areas with the greatest need for preventing and managing self-harm.

The significance of site of cut in self-harm in young people.

BACKGROUND: Self-cutting in young people is associated with high risk of repetition and suicide. It is important, therefore, to identify characteristics of self-cutting that might impact on repetition and aspects of care by staff. This study aimed to explore differences in clinical (e.g., previous self-harm) and psychological characteristics (intent, mental state, precipitants) of self-cutting in young people based on whether site of cut was visible or concealed. METHODS: Data were from a large prospective self-harm monitoring database that collected data on hospital emergency department presentations for self-harm in the City of Manchester, UK, between 2005 and 2011. Clinical and psychological characteristics, as well as onward referral/clinical management from the emergency department, of 799 young people (totalling 1,196 episodes) age 15-24 who self-cut in visible or concealed areas were compared using logistic regression. RESULTS: During the study period 500 (40%) episodes were in a concealed location. Concealed self-cutting was more likely to be precipitated by specific self-reported precipitants such as abuse and characterised by the following: previous self-harm, current psychiatric treatment, premeditation, and greater risk of repetition within the study period. Receiving a psychosocial assessment and referral to psychiatric services from the emergency department were less likely, however. Repetition and referral to psychiatric treatment were not significantly associated with site of injury when adjusting for other factors. CONCLUSIONS: There are meaningful differences in characteristics associated with location of cut. We recommend that all young people who present to hospital following self-harm receive a psychosocial assessment, in line with NICE guidance.

Mortality in children and adolescents following presentation to hospital after non-fatal self-harm in the Multicentre Study of Self-harm: a prospective observational cohort study.

BACKGROUND: Self-harm and suicide in children and adolescents are growing problems, and self-harm is associated with a significant risk of subsequent death, particularly suicide. Long-term follow-up studies are necessary to examine the extent and nature of this association. METHODS: For this prospective observational cohort study, we used data from the Multicentre Study of Self-harm in England for all individuals aged 10-18 years who presented to the emergency department of five study hospitals in Oxford, Manchester, and Derby after non-fatal self-harm between Jan 1, 2000, and Dec 31, 2013. Deaths were identified through the Office for National Statistics via linkage with data from NHS Digital up until Dec 31, 2015. The key outcomes were mortality after presentation to hospital for self-harm, categorised into suicide, accidental deaths, and death by other causes. We calculated incidence of suicide since first hospital presentation for self-harm and used Cox proportional hazard models to estimate the associations between risk factors (sex, age, previous self-harm) and suicide. FINDINGS: Between Jan 1, 2000, and Dec 31, 2013, 9303 individuals aged 10-18 years presented to the study hospitals. 130 individuals were excluded because they could not be traced on the national mortality register or had missing data on sex or age, thus the resulting study sample consisted of 9173 individuals who had 13 175 presentations for self-harm. By the end of the follow-up on Dec 31, 2015, 124 (1%) of 9173 individuals had died. 55 (44%) of 124 deaths were suicides, 27 (22%) accidental, and 42 (34%) due to other causes. Of the 9173 individuals who presented for self-harm, 55 (0·6%) died by suicide. Most suicide deaths involved self-injury (45 [82%] of 55 deaths). Switching of method between self-harm and suicide was common, especially from self-poisoning to hanging or asphyxiation. The 12-month incidence of suicide in this cohort was more than 30 times higher than the expected rate in the general population of individuals aged 10-18 years in England (standardised mortality ratio 31·0, 95% CI 15·5-61·9). 42 (76%) of 55 suicides occurred after age 18 years and the annual incidence remained similar during more than 10 years of follow-up. Increased suicide risk was associated with male sex (adjusted hazard ratio 2·50, 95% CI 1·46-4·26), being an older adolescent at presentation to hospital for self-harm (1·82, 0·93-3·54), use of self-injury for self-harm (2·11, 1·17-3·81; especially hanging or asphyxiation [4·90, 1·47-16·39]), and repeated self-harm (1·87, 1·10-3·20). Accidental poisoning deaths were especially frequent among males compared with females (odds ratio 6·81, 95% CI 2·09-22·15). INTERPRETATION: Children and adolescents who self-harm have a considerable risk of future suicide, especially males, older adolescents, and those who repeated self-harm. Risk might persist over several years. Switching of method from self-harm to suicide was common, usually from self-poisoning to self-injury (especially hanging or asphyxiation). Self-harm is also associated with risk of death from accidental poisoning, particularly involving drugs of abuse, especially in young males. FUNDING: UK Department of Health and Social Care.
