Deliberate self-harm in rural and urban regions: A comparative study of prevalence and patient characteristics

Travel Distance to Hospital Is Associated With Self-Harm Hospital Presentation But Not Suicide

Background: Travel distance to hospital emergency departments (EDs) may be a more influential factor in the spatial variation in hospital-presenting self-harm than for suicide deaths. Aims: We investigated the associations of travel distance to the nearest ED with self-harm hospital presentations and suicides in a large city in Taiwan. Method: Data for self-harm and suicide were extracted from Taiwan's National Suicide Surveillance System (2012-2016). Results: Adjusted analyses using Bayesian hierarchical models showed that a longer travel distance to the nearest hospital ED was associated with lower self-harm hospital presentation rates but not suicide rates. Limitations: This is an ecological study; the area-level associations could not be directly implied at the individual level. Conclusion: Living in remote neighborhoods could be a barrier to seeking medical help after self-harm, and this has implications for suicide, surveillance, prevention and intervention strategies.

Contextual influences on deliberate self-harm among Chinese university undergraduates: A representative nationwide study

BACKGROUND

Numerous studies have identified factors associated with deliberate self-harm (DSH), but environmental influences have largely been neglected. This study explored regional and university contextual factors that impact DSH among undergraduate students in China.

METHODS

Subjects in this observational cross-sectional study totaled 5016 undergraduate students, who were identified through multistage survey sampling in 22 Chinese universities. Individual-level data were obtained through a self-administered questionnaire, and environmental variables were extracted from the National Bureau of Statistics database. Multilevel logistic regression models were used to examine regional correlates of DSH.

RESULTS

The overall prevalence of self-reported DSH in the study sample was 7.5 % (95 % CI: 4.1 %, 10.9 %). The full multilevel logistic model showed university rank and city size were inversely associated with DSH prevalence (Adjusted Odds Ratio (AOR): 0.24 and 0.55). Regional unemployment rates were positively associated with DSH prevalence (AOR: 1.98, 95 % CI: 1.48, 2.65).

DISCUSSION

Contextual disparities appear to contribute to DSH among Chinese undergraduates. Preventive initiatives must focus on redressing imbalances in the allocation of social and economic resources across universities and regions.

Self-harm, in-person bullying and cyberbullying in secondary school-aged children: A data linkage study in Wales

INTRODUCTION

Although the evidence base on bullying victimization and self-harm in young people has been growing, most studies were cross-sectional, relied on self-reported non-validated measures of self-harm, and did not separate effects of in-person and cyberbullying. This study aimed to assess associations of self-harm following in-person bullying at school and cyberbullying victimization controlling for covariates.

METHODS

School survey data from 11 to 16 years pupils collected in 2017 from 39 Welsh secondary schools were linked to routinely collected data. Inverse probability weighting was performed to circumvent selection bias. Survival analyses for recurrent events were conducted to evaluate relative risks (adjusted hazard ratios [AHR]) of self-harm among bullying groups within 2 years following survey completion.

RESULTS

A total of 35.0% (weighted N = 6813) of pupils reported being bullied, with 18.1%, 6.4% and 10.5% being victims of in-person bullying at school only, cyberbullying only and both in-person bullying at school and cyberbullying respectively. Adjusting for covariates, effect sizes for self-harm were significant after being in-person bullied at school only (AHR = 2.2 [1.1-4.3]) and being both in-person bullied at school and cyberbullied (AHR = 2.2 [1.0-4.7]) but not being cyberbullied only (AHR = 1.2 [0.4-3.3]). Feeling lonely during recent summer holidays was also a robust predictor (AHR = 2.2 [1.2-4.0]).

CONCLUSIONS

We reaffirm the role of in-person bullying victimization on self-harm. Pupils were twice as likely to self-harm following in-person bullying as their nonvictimised peers. Interventions for young people that minimize the potential impacts of bullying on self-harm should also include strategies to prevent loneliness.

A Systematic Review of the Effects of Urban Living on Suicidality and Self-Harm in the UK and Ireland

We conducted a systematic review to answer the following: (a) Is there any evidence to support increased prevalence of suicidality and self-harm (i.e. self-harm or suicidality) in urban versus rural environments? (b) What aspects of the urban environment pose risk for suicidality and self-harm? Thirty-five studies met our criteria. Our findings reflect a mixed picture, but with a tendency for urban living to be associated with an increased risk of suicidality and self-harm over rural living, particularly for those living in deprived areas. Further research should focus on the clustering and additive effects of risk and protective factors for suicidality and self-harm in urban environments.

Rapid response pathway united to reduce self-harm (RUSH): a case study of a pilot pathway for children and young people

Purpose

In response to elevated local self-harm and suicide rates, and the lack of a dedicated pathway for children and young people (CYP) who self-harm, a rapid response pathway united to reduce self-harm (RUSH) was developed and implemented within Norwich (Norfolk, England). This public health case study aims to describe the pathway model and share its outcomes, learnings, and reflections over the pilot year.

Design/methodology/approach

RUSH was a community-based pilot pathway aiming to support CYP, 11–18 years old, engaging in or at risk of engaging in repeated self-harm and subsequently at risk of repeated attendance at local emergency departments. From May 2020 to April 2021, RUSH supported 61 CYP using funding from NHS England and Improvement.

Findings

This case study shares the pathway’s outcomes, through a mixed-method evaluation. Results indicate statistically significant reductions in self-harm frequency (p = 0.01) and anxiety and depression symptomatology (p < 0.001); a statistically significant increase in progress towards goals (p < 0.001); and a general downward trend in re-attendance at local emergency departments following RUSH. Findings also illustrate high service user satisfaction. Framework analysis of focus group data highlights positive experiences with hope for recommissioning from a staff perspective.

Originality/value

This study will be valuable for services looking to develop and implement a similar service provision, in response to the need to tackle self-harm rates as a broader approach to suicide prevention. In light of the NHS long-term plan (2019), it also serves as an example of how to develop and use a strategic co-production group, and work collaboratively with the voluntary, community and social enterprise sectors.

First responder, clinician, and non‐clinical support staff knowledge, attitudes, and behaviours towards people presenting for emergency care following self‐harm: a mixed evidence synthesis

This is a protocol for a Cochrane Review (qualitative). The objectives are as follows:

The objectives of this review are threefold, as follows.

Firstly, to assess the content of knowledge, attitudes, and behaviours of first responders, clinicians, and non‐clinical support staff towards service users with SH presentations. 

Secondly, to understand how service user and staff characteristics (e.g. age, gender, sociodemographic background), type of SH presentation (e.g. method, repetition), and contextual factors (e.g. hospital environment, presence of bystanders) affect the knowledge, attitudes, and behaviours of first responders, clinicians, and non‐clinical support staff in providing acute care.

Thirdly, to assess whether clinicians' knowledge, attitudes, and behaviours have evolved over time.

Patients with first versus multiple episodes of self-harm: how do their profiles differ?

BACKGROUND

Self-harm (SH) is among the strongest predictors of further episodes of SH, suicide attempt, and death by suicide. People who repeteadly harm themselves are at even higher risk for suicide. Factors influencing the repetition are important to identify when assessing suicidal risk and thereafter to offer specific interventions. Therefore, this study aimed to compare first versus multiple episodes characteristics in a large sample of patients in french-speaking Switzerland.

METHOD

We used the database from the French-speaking Swiss program for monitoring SH. Data of the psychiatric assessment of all adults admitted for SH were collected in the emergency department of four Swiss city hospitals between December 2016 and October 2019.

RESULTS

1730 episodes of SH were included. Several variables were significantly associated with multiple episodes, including diagnosis (over representation of personality disorders and under representation of anxiety disorders), professional activity (Invalidity insurance more frequent) and prior psychiatry care.

CONCLUSIONS

Patients suffering from a personality disorder and those with invalidity insurance are at risk for multiple episodes of SH and should be targeted with specific interventions.

Deliberate self-harm and associated risk factors in young adults: the importance of education attainment and sick leave

PURPOSE

The prevalence of deliberate self-harm (DSH) is high in young adults. However, few studies have examined risk in this specific age group. We, therefore, examined the relative influence and interactive nature of a wide range of potential sociodemographic and sick leave related risk factors in young adults, aged 18-35 years, using Norwegian register data.

METHODS

All subjects with at least one episode of hospital presentation for DSH registered in the Norwegian Patient Register during the period 2008-2013 were compared with age, gender and date matched population controls using a nested case-control design. The relative influence of factors and their interactions were assessed using conditional logistic regression and recursive partitioning models.

RESULTS

9 873 study cases were compared to 186 092 controls. Socioeconomic status, marital status, sick leave and several demographic factors influenced risk for DSH. Specifically, low education (OR 7.44, 95% CI 6.82-8.12), current sick leave due to psychiatric disorders (OR 18.25, 95% CI 14.97-22.25) and being previously married (OR 3.83, 95% CI 3.37-4.36) showed the highest effect sizes. Importantly, there was an interaction between education and sick leave, where those with either low education and no sick leave (OR 13.33, 95% CI 11.66-15.23) or high education and sick leave (OR 18. 87, 95% CI 17.41-24.21) were the subgroups at highest risk.

CONCLUSION

DSH in young adults is associated with multiple sociodemographic and health disadvantages. Importantly, the two high-risk subgroups imply different pathways of risk and a need for differentiated preventative efforts.

Rural youth in distress? Youth self-harm presentations to a rural hospital over 10 years

Introduction Despite growing awareness of increasing rates of youth suicide and self-harm in New Zealand, there is still little known about self-harm among rural youth. Aim This study compared: (1) rates of youth self-harm presentations between a rural emergency department (ED) and nationally available rates; and (2) local and national youth suicide rates over the decade from January 2008 to December 2017. Methods Data were requested on all presentations to Ashburton Hospital ED coded for 'self-harm' for patients aged 15-24 years. Comparative data were obtained from the coroner, Ministry of Health and the 2013 census. Analyses were conducted of the effects of age, time, repetition, method, ethnicity and contact with mental health services on corresponding suicide rates. Results Self-harm rates in Ashburton rose in the post-earthquake period (2013-17). During the peri-earthquake period (2008-12), non-Māori rates of self-harm were higher than for Māori (527 vs 116 per 100000 youth respectively), reflecting the national trend. In the post-earthquake period, although non-Māori rates of self-harm stayed stable (595 per 100000), there was a significant increase in Māori rates of self-harm to 1106 per 100000 (Chi-squared = 14.0, P < 0.001). Youth living within the Ashburton township showed higher rates than youth living more rurally. Discussion Youth self-harm behaviours, especially self-poisoning, have increased since the Canterbury earthquakes in the Ashburton rural community. Of most concern was the almost ninefold increase in Māori self-harm presentations in recent years, along with the increasing prevalence among teenagers and females. Possible explanations and further exploratory investigation strategies are discussed.

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.

Spatial patterning and correlates of self-harm in Manchester, England

AIMS

To investigate the spatial distribution of self-harm incidence rates, their socioeconomic correlates and sex/age differences using data on self-harm presentations to emergency departments from The Manchester Self-Harm Project (2003-2013).

METHODS

Smoothed standardised incidence ratios for index self-harm episodes (n = 14 771) and their associations with area-level socioeconomic factors across 258 small areas (median population size = 1470) in the City of Manchester municipality were estimated using Bayesian hierarchical models.

RESULTS

Higher numbers and rates of self-harm were found in the north, east and far southern zones of the city, in contrast to below average rates in the city centre and the inner city zone to the south of the centre. Males and females aged 10-24, 25-44 and 45-64 years showed similar geographical patterning of self-harm. In contrast, there was no clear pattern in the group aged 65 years and older. Fully adjusted analyses showed a positive association of self-harm rates with the percentage of the unemployed population, households privately renting, population with limiting long-term illness and lone-parent households, and a negative association with the percentage of ethnicity other than White British and travel distance to the nearest hospital emergency department. The area-level characteristics investigated explained a large proportion (four-fifths) of the variability in area self-harm rates. Most associations were restricted to those aged under 65 years and some associations (e.g. with unemployment) were present only in the youngest age group.

CONCLUSIONS

The findings have implications for allocating prevention and intervention resources targeted at high-risk groups in high incidence areas. Targets for area-based interventions might include tackling the causes and consequences of joblessness, better treatment of long-term illness and consideration of the accessibility of health services.

Self-harm in midlife: analysis using data from the Multicentre Study of Self-harm in England

BACKGROUND

In England suicide rates are highest in midlife (defined as age 40-59). Despite a strong link with suicide there has been little focus on self-harm in this age group.AimTo describe characteristics and treatment needs of people in midlife who present to hospital following self-harm.

METHOD

Data from the Multicentre Study of Self-harm in England were used to examine rates over time and characteristics of men and women who self-harm in midlife. Data (2000-2013) were collected via specialist assessments or hospital records. Trends were assessed by negative binomial regression models. Comparative analysis used logistic regression models for binary outcomes. Repetition and suicide mortality were assessed by Cox proportional hazards models.

RESULTS

A quarter of self-harm presentations were made by people in midlife (n = 24 599, 26%). Incidence rates increased over time in men, especially after 2008 (incidence rate ratio [IRR] 1.07, 95% CI 1.02-1.12, P < 0.01), and were positively correlated with national suicide incidence rates (r = 0.52, P = 0.05). Rates in women remained relatively stable (IRR 1.00, 95% CI 1.00-1.02, P = 0.39) and were not correlated with suicide. Alcohol use, unemployment, housing and financial factors were more common in men; whereas indicators of poor mental health were more common in women. In men and women 12-month repetition was 25%, and during follow-up 2.8% of men and 1.2% of women died by suicide.

CONCLUSION

Self-harm in midlife represents a key target for intervention. Addressing underlying issues, alcohol use and economic factors may help prevent further self-harm and suicide.Declaration of interestK.H. and N.K. are members of the Department of Health's National Suicide Prevention Advisory Group.

The association between self-harm and area-level characteristics in Northern Ireland: an ecological study

Background

Factors contributing to suicidal behaviour are complex and multi-faceted. This study took an ecological approach to examine the association between area-level factors and rates of self-harm in Northern Ireland.

Methods

Data on self-harm presentations to emergency departments (EDs) were obtained from the Northern Ireland Self-harm Registry. The study included residents of Northern Ireland aged 16–64 years. Deprivation was measured using the Northern Ireland Multiple Deprivation Measure 2017. Population density and social fragmentation were calculated using measures from the 2011 census. Associations between area-level factors and self-harm rates were explored using negative binomial regression.

Results

Between 2013 and 2015, 14 477 individuals aged 16–64 years presented to EDs in Northern Ireland following self-harm. The rate of self-harm was 472 per 100 000 and was higher for male residents (478 vs. 467). Self-harm rates were highest in urban areas—680 per 100 000 in Belfast City and 751 per 100 000 in Derry City. Rates of self-harm in Northern Ireland were more than four times higher in the most deprived areas. A positive association with rates of self-harm held for the deprivation domains of employment, crime, education, health and income. There was a moderate association with population density. Some gender differences emerged, with associations with male rates of self-harm more pronounced.

Conclusion

These findings indicate that self-harm rates are highest for those residing in highly deprived areas, where unemployment, crime and low level of education are challenges. Community interventions tailored to meet the needs of specific areas may be effective in reducing suicidal behaviour.

Spatial patterning of self-harm rates within urban areas

PURPOSE

Urban areas are usually found to have higher rates of self-harm, with deprivation the strongest predictor at area-level. We use a disease mapping approach to examine how self-harm is patterned within an urban area and its associations with deprivation, urbanness and ethnicity.

METHODS

Data from clinical records on individuals admitted for self-harm for 725 small areas in South East London were included. Bayesian hierarchical models explored the spatio-temporal patterns of self-harm admission rates and potential associations with proximity to city centre, population density, percentage greenspace and non-white ethnic-minority populations. All models were adjusted for area-level deprivation, social fragmentation and hospital of admission.

RESULTS

There were 8327 first admissions for self-harm during the study period. Self-harm admission rates varied fourfold across the study area, with lower rates close to the city centre [adjusted standardised admission ratio, closest versus furthest quartile 0.71(95% CrI 0.54-0.96)]. Deprivation was associated with self-harm but partially masked rather than explained the spatial pattern, which strengthened after adjustment. After adjustment for deprivation, hospital of admission and social fragmentation, greenspace, population density and ethnicity were not associated with self-harm rates.

CONCLUSION

Proximity to the city centre was associated with lower rates of self-harm, but the usual operationalisations of urbanness, population density and greenspace, were not. Deprivation did not explain the spatial patterning, nor did ethnicity. While nationally self-harm rates are higher in urban and deprived areas, this cannot be extrapolated to mean that within cities the inner-city is the highest risk area nor that risk will be principally patterned according to deprivation.

Paramedics' perceptions of the care they provide to people who self-harm: A qualitative study using evolved grounded theory methodology

BACKGROUND

Self-harm (SH) accounts for over 5% of the workload of emergency ambulance services, and therefore Paramedics are often the first health professional in contact with people who SH. The authors of this paper have reported elsewhere the significant gaps in our understandings which exist surrounding this early care interaction, and some of the challenges paramedics and opportunities in paramedic care for people who SH. This study aimed to explore paramedics' perceptions of caring for those who SH using Evolved Grounded Theory Methodology.

METHODS

This study took place between 2014-2016 in one UK ambulance service covering a population of three million people. Semi structured interviews were conducted, purposively sampling paramedics until saturation was reached. Interviews were recorded, transcribed verbatim, and coded through open, axial, and selective levels of coding, identifying the Basic Social Process (BSP) and developing a Grounded Theory. A second researcher (SH) independently reviewed early results, which were also member-checked with participants.

RESULTS

Eleven paramedics were interviewed. The following six categories emerged: Context; Judgements and values; Isolation and system failure; Managing risk; Competence at the boundary of mental and physical health needs; Professional, legal and ethical tensions. The BSP Decision making in a context of risk was identified. The final Grounded Theory that emerged was one of 'Wicked Complexity of paramedic care for people who SH, which includes usual factors such as tiredness and frequent callers, heightened factors including lack of support and pathways, and factors specific to SH such assessing mental health and suicide risk.

CONCLUSIONS

This study builds on a very small body of literature to have explored paramedic care for people who SH and has found that this care interaction provides uniquely complex challenges. The multiple influences within the categories defined in this study need considering conjointly when making improvements to care.

Incidence of suicide, hospital-presenting non-fatal self-harm, and community-occurring non-fatal self-harm in adolescents in England (the iceberg model of self-harm): a retrospective study

BACKGROUND

Little is known about the relative incidence of fatal and non-fatal self-harm in young people. We estimated the incidence of suicide, hospital-presenting non-fatal self-harm, and community-occurring non-fatal self-harm in adolescents in England.

METHODS

We used national mortality statistics (Jan 1, 2011, to Dec 31, 2013), hospital monitoring data for five hospitals derived from the Multicentre Study of Self-Harm in England (Jan 1, 2011, to Dec 31, 2013), and data from a schools survey (2015) to estimate the incidence of fatal and non-fatal self-harm per 100 000 person-years in adolescents aged 12-17 years in England. We described these incidences in terms of an iceberg model of self-harm.

FINDINGS

During 2011-13, 171 adolescents aged 12-17 years died by suicide in England (119 [70%] male and 133 [78%] aged 15-17 years) and 1320 adolescents presented to the study hospitals following non-fatal self-harm (1028 [78%] female and 977 [74%] aged 15-17 years). In 2015, 322 (6%) of 5506 adolescents surveyed reported self-harm in the past year in the community (250 [78%] female and 164 [51%] aged 15-17 years). In 12-14 year olds, for every boy who died by suicide, 109 attended hospital following self-harm and 3067 reported self-harm in the community, whereas for every girl who died by suicide, 1255 attended hospital for self-harm and 21 995 reported self-harm in the community. In 15-17 year olds, for every male suicide, 120 males presented to hospital with self-harm and 838 self-harmed in the community; whereas for every female suicide, 919 females presented to hospital for self-harm and 6406 self-harmed in the community. Hanging or asphyxiation was the most common method of suicide (125 [73%] of 171), self-poisoning was the main reason for presenting to hospital after self-harm (849 [71%] of 1195), and self-cutting was the main method of self-harm used in the community (286 [89%] of 322).

INTERPRETATION

Ratios of fatal to non-fatal rates of self-harm differed between males and females and between adolescents aged 12-14 years and 15-17 years, with a particularly large number of females reporting self-harm in the community. Our findings emphasise the need for well resourced community and hospital-based mental health services for adolescents, with greater investment in school-based prevention.

Suicide attempters examined in a Parisian Emergency Department: Contrasting characteristics associated with multiple suicide attempts or with the motive to die

Among patients examined after a suicide attempt in a Parisian emergency department, we aimed to compare individual characteristics of i) first time and multiple suicide attempters, ii) attempters whose principal motive was "to die" and attempters who had any other motive. Information regarding sociodemographics, clinical characteristics, prior mental health care and outgoing referral was collected in 168 suicide attempters using a standardized form. Associations of these variables with suicide attempt repetition (yes or no) and with the motive underlying the attempt (to die or not) were examined using descriptive statistics and multivariable logistic regression models. Multiple attempters were more likely to have no occupation and to report previous mental health care: mental health follow-up, psychiatric medication or psychiatric hospitalization. The motive to die was not associated with the risk of multiple suicide attempts but related to past suicidal ideation and to some specific precipitating factors, including psychiatric disorder. Patients who intended to die were also more likely to be referred to inpatient than to outpatient psychiatric care. Multiple attempters and attempters who desire to die might represent two distinct high-risk groups regarding clinical characteristics and care pathways. They would probably not benefit from the same intervention strategies.

Biting myself so I don't bite the dust: prevalence and predictors of deliberate self-harm and suicide ideation in Azorean youths

Objective:

To characterize non-suicidal self-injury (NSSI) behaviors, methods, and functions as well as suicide ideation in the adolescent population of a Portuguese community in São Miguel Island, Azores. Increasing rates of NSSI behaviors among adolescents have been observed globally, while suicidal behavior has been pointed as a major cause of death during adolescence.

Methods:

A sample of 1,763 adolescents, aged 14 to 22, was randomly drawn from public and private schools and administered a set of self-report questionnaires. Descriptive and regression analyses were used to look for specific relationships and predictors of NSSI and suicide ideation in this isolated community.

Results:

Approximately 30% of youths reported at least one NSSI behavior, a rate that is twice as high as most studies carried out in mainland Portugal and in other European countries. Biting oneself was the most frequent form of NSSI, and NSSI behaviors served predominantly automatic reinforcement purposes (i.e., regulation of disruptive emotional states). NSSI and suicide ideation encompassed different distal and proximal risk factors.

Conclusions:

Exploring and characterizing these phenomena is necessary to provide a better understanding, enhance current conceptualizations, and guide the development of more effective prevention and intervention strategies in youths.

Self-Harm in Adolescents: A Self-Report Survey in Schools from Lisbon, Portugal

The study aims to determine the prevalence of self-harm (SH) and related psychosocial factors in a large sample of Portuguese adolescents. A total of 1,713 pupils, aged 12 to 20 years, completed an anonymous questionnaire in a school setting. In all, 7.3% reported at least 1 episode of SH: rates were 3 times higher for females than males. Almost half reported repeated SH, most commonly self-cutting. Anxiety, depression, and substance abuse were linked to SH, and particularly repeated SH. Anxiety, trouble with the police, and exposure to SH or suicide of others, were independently associated with SH in both genders. These findings indicate that SH is a public health concern in Portugal as in other European countries.

Surgical and psychiatric profile of patients who self-harm by burning in a regional burn unit over an 11-year period

Introduction

Patients admitted to hospital for deliberate self-harm by burning (DSHB) provide a challenge for medical, surgical and psychological management. We retrospectively reviewed all the patients admitted to a Scottish regional burn unit with DSHB over an 11-year period to assess demographics and outcome.

Methods

Ward admission data were used to identify DSHB patients admitted to the South East Scotland regional burn unit in Livingston, UK between 2002 and 2012, as well as a control group of accidental burn patients. Data were extracted concerning burn injury, psychiatric history and inpatient management.

Results

A total of 53 DSHB patients with 58 attendances over the 11-year period were compared to 49 accidental burns patients. Compared to controls, DSHB patients were more likely to be unemployed, live alone and have a previous psychiatric diagnosis ( p < 0.01). DSHB patients had more severe burns, a longer hospital stay and were more likely to undergo surgery ( p < 0.01). DSHB patients with previous self-harm, suicide attempts and diagnoses of personality and eating disorder all had significantly less severe burns than DSHB patients without these risk factors ( p < 0.05).

Conclusions

In our experience, DSHB patients have more severe burn injuries and require longer, resource-intensive hospital stays. Burn units should have an appropriate specialist psychologist/psychiatrist who works within the Burn multi-disciplinary team to help manage this complex group of patients’ healthcare needs and reduce their risk of further self-harm.

Epidemiology and trends in non-fatal self-harm in three centres in England, 2000-2012: findings from the Multicentre Study of Self-harm in England

OBJECTIVES

Self-harm is a major health problem in many countries, with potential adverse outcomes including suicide and other causes of premature death. It is important to monitor national trends in this behaviour. We examined trends in non-fatal self-harm and its management in England during the 13-year period, 2000-2012.

DESIGN AND SETTING

This observational study was undertaken in the three centres of the Multicentre Study of Self-harm in England. Information on all episodes of self-harm by individuals aged 15 years and over presenting to five general hospitals in three cities (Oxford, Manchester and Derby) was collected through face-to-face assessment or scrutiny of emergency department electronic databases. We used negative binomial regression models to assess trends in rates of self-harm and logistic regression models for binary outcomes (eg, assessed vs non-assessed patients).

PARTICIPANTS

During 2000-2012, there were 84,378 self-harm episodes (58.6% by females), involving 47,048 persons.

RESULTS

Rates of self-harm declined in females (incidence rate ratio (IRR) 0.98; 95% CI 0.97 to 0.99, p<0.0001). In males, rates of self-harm declined until 2008 (IRR 0.96; 95% CI 0.95 to 0.98, p<0.0001) and then increased (IRR 1.05; 95% CI 1.02 to 1.09, p=0.002). Rates of self-harm were strongly correlated with suicide rates in England in males (r=0.82, p=0.0006) and females (r=0.74, p=0.004). Over 75% of self-harm episodes were due to self-poisoning, mainly with analgesics (45.7%), antidepressants (24.7%) and benzodiazepines (13.8%). A substantial increase in self-injury occurred in the latter part of the study period. This was especially marked for self-cutting/stabbing and hanging/asphyxiation. Psychosocial assessment by specialist mental health staff occurred in 53.2% of episodes.

CONCLUSIONS

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.

Beyond medicalization: Self-injuring acts revisited

For too long, medical/psychiatric and psychological studies, with focus on emotional sensitivity, personality traits, and correlation with psychopathology, have dominated research on self-injuring acts. The phenomenon thus has been defined as a predominantly medical issue. However, a large body of community prevalence studies show self-injuring acts to be a common phenomenon in society, and most of those who self-injure are unknown in psychiatric or other clinical settings. This article describes and analyzes the medicalization of self-injuring acts and argues a need to move research on self-injuring acts out of the medical paradigm. There is a need to explicitly explore the impact of social, cultural, structural, and gendered factors surrounding and influencing self-injuring acts. A non-medical approach, beyond the limits of the medical perspective, would feed research forward and create a more nuanced view on this widespread social phenomenon.

Pattern of acute poisoning at two urban referral hospitals in Lusaka, Zambia

BACKGROUND

Poisoning remains an important public health problem contributing significantly to the global burden of disease. Evidence on the exact burden and pattern of acute poisoning in Zambia is limited. We aimed to characterise acute poisoning with regard to demographic and epidemiologic factors of cases reported at the University Teaching Hospital and Levy Mwanawasa General Hospital; two large referral hospitals in Lusaka, Zambia.

METHODS

This was a cross-sectional study involving retrospective collection of data on all poisoning cases recorded in hospital records from 1 January to 31 December 2012. A pretested data collection form was used to extract demographic and other data such as poisonous agents used, circumstance of poisoning, route and outcome of poisoning. All analyses were performed in STATA (StataCorp. 2013. Stata Statistical Software: Release 13. College Station, TX: StataCorp LP).

RESULTS

A total of 873 poisoning cases were reviewed with almost similar proportions of males (52 %) and females (49 %). Poisoning cases were highest in the 0-12 years age category (36 %) followed by the 20-30 years age category (31 %). Accidental poisoning characterised most (65 %) cases in children aged < 13 years. The common route of exposure to poisonous agents was ingestion. Overall, the mortality rate was 2.6 per 100 cases, the majority of deaths were observed in men (78 %). Poisonous agents associated with most cases were pesticides (57 %) and pharmaceuticals (13 %).

CONCLUSIONS

The high risk of accidental poisoning observed in children calls for special health education on chemical safety, tailored for mothers and caregivers to prevent chemical exposure in this important age group whose access to toxic agents is mainly in homes or their immediate environment. The results also call for additional regulatory controls on pesticides and pharmaceuticals, which were the most common toxic agents.

Non-fatal repetition of self-harm in Taipei City, Taiwan: cohort study

BACKGROUND

Repeat self-harm is an important risk factor for suicide. Few studies have explored risk factors for non-fatal repeat self-harm in Asia.

AIMS

To investigate the risk of non-fatal repeat self-harm in a large cohort of patients presenting to hospital in Taipei City, Taiwan.

METHOD

Prospective cohort study of 7601 patients with self-harm presenting to emergency departments (January 2004-December 2006). Survival analysis was used to examine the rates, timing and factors associated with repeat self-harm.

RESULTS

In total 778 (10.2%) patients presented to hospital with one or more further episodes of self-harm. The cumulative risk of non-fatal repetition within 1 year of a self-harm episode was 9.3% (95% CI 8.7-10.1). The median time to repetition within 1 year was 105 days. Females had a higher incidence of repeat self-harm than males (adjusted hazard ratio 1.25, 95% CI 1.05-1.48) but males had shorter median time to repetition (107 v. 80 days). Other independent risk factors for repeat self-harm within 1 year of an index episode were: young age, self-harm by medicine overdose and increasing number of repeat episodes of self-harm.

CONCLUSIONS

The risk of non-fatal repeat self-harm in Taipei City is lower than that seen in the West. Risk factors for repeat non-fatal self-harm differ from those for fatal self-harm. The first 3 months after self-harm is a crucial period for intervention.

Self-harm and ethnicity: A systematic review

AIMS

This review will focus on the rates, clinical characteristics, risk factors and methods of self-harm and suicide in different ethnic groups in the United Kingdom, providing an update synthesis of recent literature.

METHODS

Studies that met the inclusion criteria between 2003 and 2013 were reviewed using the following databases: MEDLINE, PsycINFO, EMBASE and CINAHL. The methodological quality of each study was then assessed using a structured scoring system.

RESULTS

A total of 2,362 articles were retrieved, 10 of which matched the inclusion criteria were reviewed. Significant differences were found in the rates of self-harm between ethnic groups with Asian males being least likely to self-harm and Black females being most likely to self-harm. Also, Black and South Asian people were less likely to repeat self-harm. Factors that may help protect or predispose individuals to self-harm or attempt suicide (such as religion, mental health and coping styles) also differ between ethnic groups.

CONCLUSIONS

There are clear ethnic differences in self-harm and suicide, which may be affected by factors such as cultural pressures and prevalence of mental illness. An awareness of these differences is vital to help prevent further attempts of self-harm and suicide. Further research into differences between ethnic and cultural groups and self-harm continues to be important.

Hospital-Treated Deliberate Self-Harm in the Western Area of Northern Ireland

Background: The Northern Ireland Registry of Deliberate Self-Harm was established as an outcome of the Northern Ireland Suicide Prevention Strategy and Action Plan - Protect Life, beginning in the Western Health and Social Care Trust area. Aims: The study aimed to establish the incidence of hospital-treated deliberate self-harm in the Western Area of Northern Ireland, and to explore the profile of such presentations. Method: Deliberate self-harm presentations made to the three hospital emergency departments operating in the area during the period 2007-2012 were recorded. Results: There were 8,175 deliberate self-harm presentations by 4,733 individuals. Respectively, the total, male, and female age-standardized incidence rate was 342, 320, and 366 per 100,000 population. City council residents had a far higher self-harm rate. The peak rate for women was among 15-19-year-olds (837 per 100,000) and for men was among 20-24-year-olds (809 per 100,000). Risk of repetition was higher in 35-44-year-old patients if self-cutting was involved, but was most strongly associated with the number of previous self-harm presentations. Conclusion: The incidence of hospital-treated self-harm in Northern Ireland is far higher than in the Republic of Ireland and more comparable to that in England.

Use of health services following self-harm in urban versus suburban and rural areas: a national cross-sectional study

OBJECTIVES

This study examines whether there is a difference between urban versus suburban and rural adolescents in their use of health services following two types of self-harm distinguished as self-harm with or without suicide intent.

SETTING

A nationwide cross-sectional school survey of 11 406 Norwegian adolescents aged 13-19 years in 73 Norwegian junior and senior high schools.

PARTICIPANTS

Adolescents who reported self-harm and provided valid responses to a follow-up question about having received subsequent help or treatment (n=959) were included in the study. Adolescents were divided into urban versus suburban and rural depending on: (1) the location of municipalities where they attended school and (2) the place of residence. Associations between urban versus suburban and rural areas and the use of health services following self-harm were assessed in those who self-harmed with and without suicide intent.

PRIMARY OUTCOME MEASURE

Use of health services following self-harm.

RESULTS

1 in 4 adolescents reported using health services following self-harm. Adolescents reporting self-harm with suicide intent were more likely to use health services than those who self-harmed without suicide intent. Following self-harm without suicide intent, adolescents in urban areas were four times more likely to use health services than adolescents in suburban and rural areas. There was no statistically significant area difference in the use of health services following self-harm with suicide intent.

CONCLUSIONS

This study found a geographical variation in the use of health services following self-harm without suicide intent, but not following self-harm with suicide intent. Differences in perception of self-harm and help-seeking behaviour between areas and different accessibility to services are suggested as possible explanations. There is a need to better understand how the interplay between individual characteristics and accessibility to services influences adolescents' use of health services following self-harm. We suggest that multilevel models are a valuable approach to achieve this goal.

Assessing the impact of socioeconomic variables on small area variations in suicide outcomes in England

Ecological studies of suicide and self-harm have established the importance of area variables (e.g., deprivation, social fragmentation) in explaining variations in suicide risk. However, there are likely to be unobserved influences on risk, typically spatially clustered, which can be modeled as random effects. Regression impacts may be biased if no account is taken of spatially structured influences on risk. Furthermore a default assumption of linear effects of area variables may also misstate or understate their impact. This paper considers variations in suicide outcomes for small areas across England, and investigates the impact on them of area socio-economic variables, while also investigating potential nonlinearity in their impact and allowing for spatially clustered unobserved factors. The outcomes are self-harm hospitalisations and suicide mortality over 6,781 Middle Level Super Output Areas.

A nationwide, population-based, long-term follow-up study of repeated self-harm in Taiwan

Background

Previous follow-up studies of repeated self-harm show that the cumulative risk of repeated self-harm within one year is 5.7%–15%, with females at greatest risk. However, relatively few studies have focused on the Far East. The objective of this study was to calculate the cumulative risk of repeated self-harm over different lengths of follow-up time (3 months, 6 months, and 1–8 years), to determine factors influencing repeated self-harm and to explore the interaction between gender and self-harm methods.

Methods

We used self-harm patient who hospitalized due to first-time self-harm between 2000 and 2007 from 1,230 hospitals in Taiwan. Hospitalization for repeated self-harm among members of this cohort was tracked after 3 months, 6 months, and 1–8 years. Tracking continued until December 31, 2008. We analyzed the cumulative risk and risk factors of repeated self-harm by using negative binomial regression.

Results

Of the 39,875 individual study samples, 3,388 individuals (8.50%) were found to have repeatedly self-harmed. The cumulative risk of repeated self-harm within three months was 7.19% and within one year was 8%. Within 8 years, it was 8.70%. Females were more likely to repeatedly self-harm than males (RR = 1.21, 95% CI = 1.15–1.76). The main method of self-harm was solid or liquid substances (RR = 1.88, 95% CI = 1.23–2.04) or cutting or piercing (RR = 1.36, 95% CI = 1.02–1.82), and in patients with psychiatric disorders were more likely to self-harm (RR = 1.61, 95% CI = 1.48–1.75).

Conclusions

The key time for intervention for repeated self-harm is within three months. Appropriate prevention programs should be developed based on gender differences.
