Abstract
INTRODUCTION European countries use various terminologies for self-harm and attempted suicide, which are sometimes used interchangeably. This complicates cross-country comparisons of incidence rates. This scoping review aimed to examine the definitions used and the possibilities to identify and compare incidence rates of self-harm and attempted suicide in Europe. METHODS A literature search was conducted in Embase, Medline and PsycINFO for studies published from 1990 to 2021, followed by grey literature searches. Data were collected for total populations originating from health care institutions or registries. Results were presented in tabular form supplemented by a qualitative summary by area. RESULTS A total of 3160 articles were screened, resulting in 43 studies included from databases and further 29 studies from other sources. Most studies used the term 'suicide attempt' rather than 'self-harm' and reported person-based rates with annual incidence rates from age 15+. None of the rates were considered comparable due to different reporting traditions related to classification codes and statistical approaches. CONCLUSION The present extensive literature on self-harm and attempted suicide cannot be used to compare findings between countries because of the high degree of heterogeneity among studies. International agreement on definitions and registration practices is needed to improve knowledge and understanding of suicidal behaviour.

Abstract
This study aimed to identify the sociodemographic and clinical factors associated with the occurrence and recurrence of intentional self-poisoning with medications (ISP-M), and suicide deaths by ISP-M in the state of Mato Grosso, Brazil. In this cross-sectional analytical study, we used logistic regression models to analyze data obtained through health information systems. Factors associated with use of ISP-M as a method were female gender, white skin color, occurrence in urban areas and at home. The ISP-M as a method was less reported in people presumed under the influence of alcohol. Lower chance of death by suicide using ISP-M was found among young people and adults (under 60 years old).

J Family Med Prim Care 2022; 11:233-239. [PMID: 35309643 PMCID: PMC8930158 DOI: 10.4103/jfmpc.jfmpc_1184_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 08/20/2021] [Accepted: 10/06/2021] [Indexed: 11/22/2022] Open
Abstract
Background: Deliberate self-poisoning and harm (DSPH) is an unabating problem with a wide variation in the methods used across the world. Hence, this study was conducted to understand the current spectrum of methods used for DSPH by patients in our geographic locality and catchment area with special emphasis on newer compounds and drugs used. Methods: This retrospective study included patients presenting with DSPH to the emergency department (ED) between January 2017 and December 2018. Results: This study included 1802 patients, with a mean age of 32 ± 12.7 years. Of the patients, 85% were in the young to middle age group (16–45 years). Agrochemicals (n = 604, 33.5%), drugs (n = 498, 27.6%), plant toxins (n = 150, 8.3%) and rodenticides (n = 145, 8%) were the predominantly used compounds. The major emergency resuscitation procedures required in the ED were intubation (n = 321, 18%), vasopressor support (n = 73, 4%) and cardiopulmonary resuscitation (n = 27, 1.4%). A quarter (23.2%) was discharged stable from the ED, whereas a further 56.5% were discharged stable after hospital admission. The in-hospital mortality rate was 3% (n = 47). Multivariate logistic regression analysis showed rodenticides (odds ratio (OR): 22.32; 95% confidence interval (CI): 8.05–61.88; P = 0.005) and plant poisons (OR: 23.92; 95% CI: 8.95–63.94; P = 0.005) to be the independent predictors of mortality. Conclusion: DSPH is prevalent in the highly productive young age group. Agrochemical ingestion and drug overdose are the most common methods used, whereas rodenticide and plant poisoning are associated with significant mortality.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph181910232. [PMID: 34639533 PMCID: PMC8508216 DOI: 10.3390/ijerph181910232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 09/25/2021] [Accepted: 09/26/2021] [Indexed: 12/04/2022]
Abstract
A relatively high proportion of attempted suicides employ self-poisoning with medication. Data from emergency department presentations can help to identify possible risk drug classes and provide a basis for preventive measures. This retrospective analysis included cases presenting at the emergency department of the University Hospital of Bern, Switzerland, from May 2012 to August 2016, after attempted suicide with drugs. We excluded attempted suicides with only alcohol or other non-medical substances. During the study period, there were 488 cases (466 patients) of attempted suicide with medical substances. The median patient age was 33 years (range 16–93) and 354 (73%) cases were female. The most commonly involved substances/drug classes were benzo-diazepines (n = 167, 34%), neuroleptics (n = 114, 23%) and paracetamol (n = 111, 23%). A total of 231 (47%) cases employed only a single substance. Common symptoms included somnolence (n = 245, 50%), tachycardia (n = 119, 24%) and nausea/vomiting (n = 76, 16%). In most cases, the poisoning was of minor severity (n = 231, 47%) and the patients were admitted to a psychiatric hospital (n = 264, 54%). Important preventive measures may include careful monitoring for suicidal behaviour when prescribing psychotropic drugs, in addition to restrictions in pack size. Efforts should also be made to enhance the awareness of health professionals qualified to prescribe or supply paracetamol.

Abstract
Background Concerns about the misuse of codeine led to the introduction of guidance restricting the supply of over-the-counter (OTC) codeine-containing products in Ireland in 2010. The aim of this study was to examine the impact of this guidance on the national rate of hospital-presenting self-harm involving codeine-related intentional drug overdose (IDO). Methods Presentations involving IDO to Irish general hospitals between 1 January 2007 and 31 December 2013, as recorded by the National Self-Harm Registry Ireland, were analyzed. Event-based rates per 100 000 were calculated using national population data. Poisson regression models were used to assess rate changes between pre- and post-guidance periods and to calculate excess presentations. Results Between January 2007 and December 2013, a total of 57 759 IDOs were recorded, with 4789 (8.3%) involving a codeine-containing product. The rate of codeine-related IDOs was 20% lower in the period following implementation of the guidance (incidence rate ratio: 0.80; 95% CI: 0.75 to 0.85), representing a total of 509 (95% CI: −624, −387) fewer codeine-related IDOs in that period. Reductions were observed across all ages and were more pronounced for females (0.76, 0.71 to 0.82) than males (0.87, 0.79 to 0.97). The rate of IDOs involving other drugs decreased by 3% in the same period (0.97, 0.95 to 0.98). Conclusion Our findings indicate that the rate of codeine-related IDOs was significantly lower in the period following the implementation of the guidance. There is a large body of evidence supporting the restriction of potentially harmful medication as an effective strategy in suicide prevention.

Abstract
BACKGROUND This study used individual-level linked data across general practice, emergency departments (EDs), outpatients and hospital admissions to examine contacts across settings and time by sex for self-harm in individuals aged 10-24 years old in Wales, UK. METHODS A whole population-based e-cohort study of routinely collected healthcare data was conducted. Rates of self-harm across settings over time by sex were examined. Individuals were categorised based on the service(s) to which they presented. RESULTS A total of 937 697 individuals aged 10-24 years contributed 5 369 794 person years of data from 1 January 2003 to 30 September 2015. Self-harm incidence was highest in primary care but remained stable over time (incident rate ratio (IRR)=1.0; 95% CI 0.9 to 1.1). Incidence of ED attendance increased over time (IRR=1.3; 95% CI 1.2 to 1.5) as did hospital admissions (IRR=1.4; 95% CI 1.1 to 1.6). Incidence in the 15-19 years age group was the highest across all settings. The largest increases were seen in the youngest age group. There were increases in ED attendances for both sexes; however, females are more likely than males to be admitted following this. This was most evident in individuals 10-15 years old, where 76% of females were admitted compared with just 49% of males. The majority of associated outpatient appointments were under a mental health specialty. CONCLUSIONS This is the first study to compare self-harm in people aged 10-24 years across primary care, EDs and hospital settings in the UK. The high rates of self-harm in primary care and for young men in EDs highlight these as important settings for intervention.

Abstract
BACKGROUND Intentional drug overdose (IDO) has been linked with marked increases in premature mortality risk due to suicide, accidents and other causes, yet little is known about how case fatality risk varies according to the type of drug/s taken. This study aimed to examine the incidence of IDO, to identify the predictors of fatal IDO and to establish which drugs are linked with greater risk of a fatal outcome. METHODS Data from the National Self-Harm Registry, and the National Drug-Related Deaths Index, 2007-2014, were used to calculate incidence, examine overdose characteristics and estimate case fatality risk ratios. RESULTS We examined 63,831 non-fatal and 364 fatal IDOs (incidence: 148.8 and 1.01 per 100,000 respectively). Compared to non-fatal IDOs, fatal cases were more often male (55.2% vs. 42.0%), older in age (median 44 vs. 35 years), and more frequently involved multiple drugs (78.3% vs. 48.5%). Tricyclic antidepressants were associated with a 15-fold increased risk of death and opioids a 12-fold increased risk, relative to the reference category (non-opioid analgesics). While the risk of fatal outcome was higher for males than females, the elevation in risk was greater in females when tricyclic antidepressants or opioids were taken. CONCLUSION Male gender, increasing age and multiple drug use were associated with fatal IDO outcome. Tricyclic antidepressants and opioids were associated with a significantly increased risk of death following intentional overdose. Clinicians need to consider the case fatality risk of drugs when determining treatment for patients at risk of or those who have previously harmed themselves.

Abstract
OBJECTIVE The aim of this study was to describe presentations to hospital as a result of self-harm or suicidal ideation and to examine patterns of repetition. METHOD Presentations made to hospital emergency departments in Northern Ireland following self-harm and ideation between April 2012 and March 2017 were recorded by the Northern Ireland Registry of Self-harm. Person-based rates per 100,000 were calculated using national population estimates. Risk of repeat attendance to hospital was examined using Kaplan-Meier analyses. RESULTS A total of 62,213 presentations to emergency departments following self-harm or with ideation were recorded. The rate of self-harm was more than twice the rate of hospital-presenting ideation. Rates of ideation were higher among men, and both self-harm and ideation rates peaked for girls aged 15-19 and men aged 20-24 years. The cumulative probability of repeat attendance to hospital was higher following ideation (52% after 12 months), primarily because 12% of ideation presentations were followed by a subsequent self-harm presentation, whereas 4% of self-harm presentations were followed by ideation. CONCLUSIONS Our findings indicate that hospital presenters with ideation are at high risk of future self-harm. The transition from ideation to suicidal behaviour is important to consider and research could inform effective and early intervention measures.

Medication used in intentional drug overdose in Flanders 2008-2013. PLoS One 2019; 14:e0216317.

Abstract
Background Intentional drug overdose is the most common method of self-harm. As psychiatric disorders are very common in self-harm patients, the medication used to treat these disorders can become the means for the self-harm act. The present study aimed at investigating an association between the use of prescribed medication (analgesics and antipyretics, anti-epileptics, antipsychotics, antidepressants and psychostimulants) as a method of self-harm and prescription rates of this medication in Flanders. We investigated the possible effect of gender, alcohol use during the self-harm act and a history of self-harm. Methods Data from the multicenter study of self-harm in Flanders between 2008 and 2013 were used. The significance of differences in percentages was calculated by GEE and the strength by odds ratios (OR). Results There was an increase in the odds of using antidepressants (0.8%) and antipsychotics (2%) among females when the rate of prescription increases. Analgesics and antipyretics (39.3/1,000) and antidepressants (124.9/1,000) were the most commonly prescribed drugs among females. Antidepressants (63.9/1,000) and antipsychotics (26.5/1,000) were the most commonly prescribed drugs among males. Antidepressants and analgesics and antipyretics were the most frequently used medications for self-harm. Analgesics and antipyretics during the self-harm act were more common among first-timers, while repeaters more commonly overdosed using antipsychotics and antidepressants. Conclusion These findings suggest that the availability of medication via prescriptions plays an important role in the choice of the medication ingested during the self-harm act. Precautions are necessary when prescribing medication, including restrictions on the number of prescriptions and the return of unused medication to pharmacies after cessation of treatment. These issues should be a focus of attention in the education and training of physicians and pharmacists.

Abstract
Background Intentional drug overdose (IDO) is the most common form of hospital-treated self-harm, yet no national study has systematically classified the range of drugs involved using a validated system. We aimed to determine the profile of patients engaging in overdose, to identify drugs frequently used and to quantify the contributions of multiple drug use and alcohol involvement. Methods Between 2012 and 2014, the National Self-Harm Registry, Ireland recorded 18 329 presentations of non-fatal IDO to Irish emergency departments. Information on demographic and overdose characteristics were obtained. Drugs were categorized using the Anatomical Therapeutic Chemical classification system. Results Analgesics (32.4%), antidepressants (21.9%), anxiolytics (21.2%) and hypnotics and sedatives (21.0%) were the most frequently used drugs types involved in overdose. Presentations involving analgesic and antidepressant medication were more common for females whereas males more often took illegal, anxiolytic and hypnotic and sedative drugs. Overdoses with drugs other than those which affect the nervous system were identified, including musculoskeletal drugs, taken in 12.0% of presentations. Paracetamol was the most frequently used drug, particularly among females (32.0%) and persons under 25 years (36.2%). Alcohol was most often present in overdoses involving anxiolytics and illegal drugs. Multiple drug use was a factor in almost half (47.1%) of presentations. Conclusions People who engage in IDO frequently take prescription only or sales restricted drugs, often involving alcohol and/or multiple drug use. These findings highlight the importance of addressing drug and alcohol misuse, potential inappropriate prescribing and the enforcement of legislation restricting specific drug sales.

Abstract
Abstract
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.

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.

A network analysis. J Affect Disord 2018; 240:262-270.

Abstract
BACKGROUND A history of self-harm is a major risk factor for suicide. Some patients are more likely than others to repeat suicidal behaviour after an episode of self-harm. Insight in the relation between current thoughts of self-harm, motives for the self-harm episode and perceived problems may improve prevention strategies. Network analysis allows to investigate the co-occurence of these factors and their association with each other. METHODS Ising model based networks are estimated on data collected between 2007-2015 within the Multicentre Study of Self-harm in Flanders. Patients were interviewed within 24 hours after hospitalization by a trained professional on their motives for the episode of self-harm and their perceived problems. Additionally, they were asked whether they had current thoughts of self-harm. Network analyses are used to determine which motives and problems are uniquely related to current thoughts of self-harm, and which are most central in the network. RESULTS Data were used of 6068 patients (2279 males and 3789 females). Four internal motives (wish to die, lost control, escape from situation, situation was unbearable), one external motive (show somebody how hopeless I was) and four perceived problems (psychiatric, loneliness, trauma, rejection) are directly related to current thoughts of self-harm. Of all motives and problems, the motive a wish to die is most strongly related to current thoughts of self-harm. However, external motives are more central in the network when compared to internal motives and perceived problems. LIMITATIONS Data most probably refer to a selected group of self-harm patients as many individuals who self-harm do not come to the attention of hospital services. Patients might be reluctant to tell professionals they had current thoughts of self-harm. CONCLUSIONS Many internal motives and problems are directly related to current thoughts of self-harm, but external motives are more central in the network. The clinically most important motive (wish to die) does not play a central role in the network.

Abstract
PURPOSE Rates of hospital-treated self-harm are highest among young people. The current study examined trends in rates of self-harm among young people in Ireland over a 10-year period, as well as trends in self-harm methods. METHODS Data from the National Self-Harm Registry Ireland on presentations to hospital emergency departments (EDs) following self-harm by those aged 10-24 years during the period 2007-2016 were included. We calculated annual self-harm rates per 100,000 by age, gender and method of self-harm. Poisson regression models were used to examine trends in rates of self-harm. RESULTS The average person-based rate of self-harm among 10-24-year-olds was 318 per 100,000. Peak rates were observed among 15-19-year-old females (564 per 100,000) and 20-24-year-old males (448 per 100,000). Between 2007 and 2016, rates of self-harm increased by 22%, with increases most pronounced for females and those aged 10-14 years. There were marked increases in specific methods of self-harm, including those associated with high lethality. CONCLUSIONS The findings indicate that the age of onset of self-harm is decreasing. Increasing rates of self-harm, along with increases in highly lethal methods, indicate that targeted interventions in key transition stages for young people are warranted.

Abstract
BACKGROUND Suicidal behaviour is the end result of the complex relation between many factors which are biological, psychological and environmental in nature. Network analysis is a novel method that may help us better understand the complex association between different factors. AIMS To examine the relationship between suicidal symptoms as assessed by the Beck Scale for Suicide Ideation and future suicidal behaviour in patients admitted to hospital following a suicide attempt, using network analysis. METHOD Secondary analysis was conducted on previously collected data from a sample of 366 patients who were admitted to a Scottish hospital following a suicide attempt. Network models were estimated to visualise and test the association between baseline symptom network structure and suicidal behaviour at 15-month follow-up. RESULTS Network analysis showed that the desire for an active attempt was found to be the most central, strongly related suicide symptom. Of the 19 suicide symptoms that were assessed at baseline, 10 symptoms were directly related to repeat suicidal behaviour. When comparing baseline network structure of repeaters (n=94) with the network of non-repeaters (n=272), no significant differences were found. CONCLUSIONS Network analysis can help us better understand suicidal behaviour by visualising the complex relation between relevant symptoms and by indicating which symptoms are most central within the network. These insights have theoretical implications as well as informing the assessment and treatment of suicidal behaviour. DECLARATION OF INTEREST None.

Abstract
Although suicide is a major public health issue worldwide, we understand little of the onset and development of suicidal behaviour. Suicidal behaviour is argued to be the end result of the complex interaction between psychological, social and biological factors. Epidemiological studies resulted in a range of risk factors for suicidal behaviour, but we do not yet understand how their interaction increases the risk for suicidal behaviour. A new approach called network analysis can help us better understand this process as it allows us to visualize and quantify the complex association between many different symptoms or risk factors. A network analysis of data containing information on suicidal patients can help us understand how risk factors interact and how their interaction is related to suicidal thoughts and behaviour. A network perspective has been successfully applied to the field of depression and psychosis, but not yet to the field of suicidology. In this theoretical article, I will introduce the concept of network analysis to the field of suicide prevention, and offer directions for future applications and studies.
