Suicide and accidental deaths in children and adolescents in England and Wales, 2001-2010

Suicide and Self-Harm in Recent Immigrants in Ontario, Canada: A Population-Based Study

OBJECTIVE

To estimate the rates of suicide and self-harm among recent immigrants and to determine which immigrant-specific risk factors are associated with these outcomes.

METHODS

Population-based cohort study using linked health administrative data sets (2003 to 2017) in Ontario, Canada which included adults ≥18 years, living in Ontario (N = 9,055,079). The main exposure was immigrant status (long-term resident vs. recent immigrant). Immigrant-specific exposures included visa class and country of origin. Outcome measures were death by suicide or emergency department visit for self-harm. Cox proportional hazards estimated adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs).

RESULTS

We included 590,289 recent immigrants and 8,464,790 long-term residents. Suicide rates were lower among immigrants (n = 130 suicides, 3.3/100,000) than long-term residents (n = 6,354 suicides, 11.8/100,000) with aHR 0.3, 95% CI, 0.2 to 0.3. Male-female ratios in suicide rates were attenuated in immigrants. Refugees had 2.1 (95% CI, 1.3 to 3.6; rate 6.1/100,000) and 2.8 (95% CI, 2.5 to 3.2) times the likelihood of suicide and self-harm, respectively, compared with nonrefugee immigrants. Self-harm rate was lower among immigrants (n = 2,256 events, 4.4/10,000) than long-term residents (n = 68,039 events, 9.7/10,000 person-years; aHR 0.3; 95% CI, 0.3 to 0.3). Unlike long-term residents, where low income was associated with high suicide rates, income was not associated with suicide among immigrants and there was an attenuated income gradient for self-harm. Country of origin-specific analyses showed wide ranges in suicide rates (1.4 to 9.9/100,000) and self-harm (1.8 to 14.9/10,000).

CONCLUSION

Recent immigrants have lower rates of suicide and self-harm and different sociodemographic predictors compared with long-term residents. Analysis of contextual factors including immigrant class, origin, and destination should be considered for all immigrant suicide risk assessment.

Hanging and near hanging in children: injury patterns and a clinical approach to early management

Near hanging refers to survival following suspension by the neck. This is a devastating injury which can lead to mortality or serious long-term morbidity. Children and young people present to emergency departments following accidental or deliberate near hanging. This article describes the patterns of injury, the initial management and important prognostic factors.

Predictive validity and interrater reliability of the FACE-CARAS toolkit in a CAMHS setting

BACKGROUND

The FACE-CARAS (Functional Analysis in Care Environments-Child and Adolescent Risk-Assessment Suite) toolkit has been developed to support practitioners in Child and Adolescent Mental Health Services (CAMHS) in performing a structured risk assessment. It covers a number of risk domains including violence, suicide, self-harm, experienced abuse, and exploitation. Interrater and internal reliability has already been established but not predictive validity.

AIMS/HYPOTHESIS

Our aim was to establish the predictive validity of the FACE-CARAS in a CAMHS population.

METHODS

Records from 123 young people with FACE-CARAS ratings completed by clinicians were examined in a retrospective file review to extract data on a relevant list of adverse outcomes at three and at 6 months following the assessment. Although this was not a prospective longitudinal study, researchers were blind to the clinicians' ratings, allowing valid testing of predictive power. Cases were drawn from across generic and specialist CAMHS teams in approximately equal proportions. Data were analysed using receiver operator characteristic statistics.

RESULTS

Areas under the curve values in five of the seven risk areas approached or were greater than 0.8 indicated that the FACE-CARAS profile score was a good potential predictor of risks of self-harm, suicidal behaviours, serious self-neglect, abuse or exploitation by others, and violence to others at both 3 and 6 months. It was weakly "predictive" of accidental self-harm and no better than chance at signalling physical ill health.

CONCLUSIONS

Findings support the use of the "profile summary" section of the tool as likely to generate clinically useful risk predictions. We were concerned that clinical use of the scale did not conform to research standards and often left subscales incompletely rated; however, the fact that the tool nonetheless proved a good predictor of most key adversities under scrutiny may add weight to its value in clinical practice. Further work with the FACE-CARAS subscales is recommended.

Suicide in adolescents: findings from the Swiss National cohort

Suicide in adolescents is the second most common cause of death in this age group and an important public health problem. We examined sociodemographic factors associated with suicide in Swiss adolescents and analysed time trends in youth suicide in the Swiss National Cohort (SNC). The SNC is a longitudinal study of the whole Swiss resident population, based on linkage of census and mortality records. We identified suicides in adolescents aged 10-18 years from 1991 to 2013. A total of 2.396 million adolescents were included and 592 suicides were recorded, corresponding to a rate of 3.7 per 100,000 [95% confidence interval (CI) 3.4-4.0]. Rates increased with age from 0.0 per 100,000 at age 10 years to 14.8 per 100,000 (95% CI 12.6-17.5) at 18 years in boys, and from 0.0 to 5.4 per 100,000 (4.1-7.2) in girls. Being a boy, living in a single parent household, being an only or middle-born child, and living in rural regions were factors associated with a higher rate of suicide. Hanging was the most common method in boys, and railway suicides were most frequent in girls. There was no clear evidence for an increase or decrease over calendar time. We conclude that familial and socioeconomic factors including type of household, birth order and urbanity are associated with youth suicide in Switzerland. These factors should be considered when designing prevention programmes for youth suicide.

Suicide patterns in children and adolescents: a review from a pediatric institution in England

Suicide is a catastrophic event to both families and communities yet it is potentially preventable. This study aims to determine incidence and patterns of suicide in children and young adolescents in our region, raise awareness of this entity as a potentially preventable cause of death in this age group, and identify its possible associated risk factors. We retrospectively reviewed suicide cases presenting as sudden unexpected death in children and adolescents that underwent coronial post-mortems at our institution. This is the largest pathological review of completed suicide in children and young adolescents within a single institution in the United Kingdom. We identified 23 suicide cases during a 12 year period from 2003 to 2015, in which 18 cases (78%) were male and 5 cases (22%) were female. The age range was from 8 to 16 years (mean age 12.82 +/- 2.52 SD). With the exception of one case, all of the victims were Caucasian. The majority, 19 cases (81%), were found dead inside their place of residence, 15 of whom were discovered in their own bedrooms. Twenty-one cases (91%) died from neck compression due to hanging; 6 cases (26%) had used the cord of a dressing gown and 5 (22%) opted to use a belt as the ligature. Two cases (9%) that died from multiple-drug toxicity were female. In 7 cases (30.5%) there was evidence of self-harm and in 3 cases (13%) there was a history of previous suicide attempts. Petechial hemorrhages were found at autopsy in more than half of hanging victims and only three cases (14%) displayed dual distribution of post-mortem hypostasis (back and legs). Seven victims (30.5%) left some form of suicide message to family members and friends, 2 of which wrote the message on their arm. Parental separation, conflict with parents, and depression, were common amongst decedents prior to committing suicide. Substance abuse was uncommon in suicide within our cases. Valuable information is available from thorough review of suicide data in children and young adolescents from a single institution. Pathologists and clinicians can play crucial roles in identifying potential risk factors that may contribute to prevent future deaths.

Influences on antidepressant prescribing trends in the UK: 1995-2011

PURPOSE

The number of antidepressants prescribed in the UK has been increasing over the last 25 years; however, the reasons for this are not clear. This study examined trends in antidepressant prescribing in the UK between 1995 and 2011 according to age, sex, and drug class, and investigated reasons for the increase in prescribing over this period.

METHODS

This is a retrospective analysis of antidepressant prescribing data from the Clinical Practice Research Datalink: a large, anonymised, primary care database in the UK. The dataset used in this study included 138 practices, at which a total of 1,524,201 eligible patients were registered across the 17-year period. The proportion of patients who received at least one antidepressant prescription and the number of patients who started a course of antidepressants were calculated for each year of the study. We used person years (PY) at risk as the denominator. The duration of treatment for those starting antidepressants was also examined.

RESULTS

23% of patients were prescribed an antidepressant on at least one occasion over the 17-year study period. Antidepressant prescriptions rose from 61.9 per 1000 PY in 1995 to 129.9 per 1000 PY in 2011. This was largely driven by an increase in prescribing of selective serotonin reuptake inhibitors and 'other' antidepressants. In contrast, incidence rates of those starting antidepressants remained relatively stable (1995: 21.3 per 1000 PY; 2011: 17.9 per 1000 PY). The duration of treatment increased with later starting years, with an increasing proportion of long-term use, and decrease in short-term use.

CONCLUSION

The increase in antidepressant prescribing over the study period appears to be driven by an increase in long-term use of these medications.

Trends in external causes of child and adolescent mortality in Poland, 1999-2012

OBJECTIVES

To examine the pattern and trend of deaths due to external causes among Polish children and adolescents in 1999-2012, and to compare trends in Poland's neighboring countries.

METHODS

Death records were obtained from the Central Statistical Office of Poland. External causes mortality rates (MR) with 95 % confidence interval were calculated. The annual percentage change of MR was examined using linear regression. To compare MR with Belarus, Ukraine, Czech Republic and Germany, data from the European Mortality Database were used.

RESULTS

MR were the highest in the age 15-19 years (33.7/100,000) and among boys (22.7/100,000). Unintentional injuries including transport accidents, drowning, and suicides (especially in children over 10 years old), were the main cause of death in the analyzed groups. Between 1999 and 2012 annual MR for unintentional injuries declined substantially. MR due to injuries and poisoning in Poland were higher compared with Czech Republic and Germany and lower in comparison with Belarus and Ukraine.

CONCLUSIONS

Deaths due to unintentional injuries are still the leading cause of death among Polish children and adolescents. There are differences in death rates between Poland and neighboring countries.

Analysis of trends in adolescent suicides and accidental deaths in England and Wales, 1972-2011

BACKGROUND

Previous analyses of adolescent suicides in England and Wales have focused on short time periods.

AIMS

To investigate trends in suicide and accidental deaths in adolescents between 1972 and 2011.

METHOD

Time trend analysis of rates of suicides and deaths from accidental poisoning and hanging in 10- to 19-year-olds by age, gender and deprivation. Rate ratios were estimated for 1982-1991, 1992-2001 and 2002-2011 with 1972-1981 as comparator.

RESULTS

Suicide rates have remained stable in 10- to 14-year-olds, with strong evidence for a reduction in accidental deaths. In males aged 15-19, suicide rates peaked in 2001 before declining. Suicide by hanging is the most common method of suicide. Rates were higher in males and in 15- to 19-year-olds living in more deprived areas.

CONCLUSIONS

Suicide rates in adolescents are at their lowest since the early 1970s with no clear evidence that changes in coroners' practices underlie this trend.

Mechanisms, patterns and outcomes of paediatric polytrauma in a UK major trauma centre

Introduction Paediatric trauma is a significant burden to healthcare worldwide and accounts for a large proportion of deaths in the UK. Methods This retrospective study examined the epidemiological data from a major trauma centre in the UK between January 2012 and December 2014, reviewing all cases of moderate to severe trauma in children. Patients were included if aged ≤16 years and if they had an abbreviated injury scale score of ≥2 in one or more body region. Results A total of 213 patients were included in the study, with a mean age of 7.8 years (standard deviation [SD]: 5.2 years). The most common cause of injury was vehicle related incidents (46%). The median length of hospital stay was 5 days (interquartile range [IQR]: 4-10 days). Approximately half (52%) of the patients had to stay in the intensive care unit, for a median of 1 day (IQR: 0-2 days). The mortality rate was 6.6%. The mean injury severity score was 19 (SD: 10). Pearson's correlation coefficient showed a positive correlation for injury severity score with length of stay in hospital (p<0.001). Conclusions There is significant variation in mechanism of injury, severity and pattern of paediatric trauma across age groups. A multidisciplinary team approach is imperative, and patients should be managed in specialist centres to optimise their care and eventual functional recovery. Head injury remained the most common, with significant mortality in all age groups. Rib fractures and pelvic fractures should be considered a marker for the severity of injury, and should alert doctors to look for other associated injuries.

Unexpected deaths of children and young people in the UK

Aims and method To review the deaths of children and young people who took their own life. We conducted a retrospective analysis of serious incident reports from a National Health Service trust and reviews by the child death overview panels of the local safeguarding children boards. Results We identified 23 deaths, with annual rates varying considerably between local authorities and over time. Over half of the children (n = 13, 56%) were not known to specialist child and adolescent mental health services, with 11 having no contact with any agency at the time of their death. Hanging was the most common method (n = 20, 87%) and of these, half (n = 11, 55%) were low-level hangings. Clinical implications Training is required to improve awareness, recognition and the assessment of children at risk of taking their own life. Specialist child mental health services should directly assess plans or attempts at hanging and offer advice about the seriousness of attempting this. National data (by age) on children and young people who take their own life should be routinely published to inform clinical and preventive services.

Suicide rates in children aged 10-14 years worldwide: changes in the past two decades

BACKGROUND

Limited research is focused on suicides in children aged below 15 years.

AIMS

To analyse worldwide suicide rates in children aged 10-14 years in two decades: 1990-1999 and 2000-2009.

METHOD

Suicide data for 81 countries or territories were retrieved from the World Health Organization Mortality Database, and population data from the World Bank data-set.

RESULTS

In the past two decades the suicide rate per 100 000 in boys aged 10-14 years in 81 countries has shown a minor decline (from 1.61 to 1.52) whereas in girls it has shown a slight increase (from 0.85 to 0.94). Although the average rate has not changed significantly, rates have decreased in Europe and increased in South America. The suicide rates remain critical for boys in some former USSR republics.

CONCLUSIONS

The changes may be related to economic recession and its impact on children from diverse cultural backgrounds, but may also be due to improvements in mortality registration in South America.

A focus on recent cases of suicides among Italian children and adolescents and a review of literature

Suicidal behaviors are among the leading causes of death worldwide. The large spread of suicide suggests that educational programs and literature to parents or guardians should include information about the potential risks and potential consequences of the onset of the idea of suicide in children. We identified 55 cases of suicide among children and young adults <18-year-old occurring in Italy between 1st January, 2011 and 31st December, 2013. The results point to the need to increase our understanding of the dramatic rise in suicidal behaviors during childhood/adolescence and of the causal pathways linking these behaviors to child-adolescent mental disorders. During routine care visits, pediatricians should be skilled to recognize risk factors for adolescent suicide in order to intervene appropriately.
