Suicide in young people aged 15-24: a psychological autopsy study.

BACKGROUND: The suicide rate in young people in the United Kingdom has increased over the last decade. As there is a paucity of information about the characteristics of young suicides we have undertaken a detailed investigation of suicides in people aged 15-24 years by means of the psychological autopsy approach. METHODS: The sample consisted of 27 subjects (25 males, two females) whose deaths received a verdict of suicide (N=24) or undetermined cause (N=3). Information was collected from informant interviews, coroners' inquest notes, medical records and psychiatric case notes. A sub-sample of 22 male subjects was compared with an age-matched sample of male deliberate self-harm (DSH) patients. RESULTS: Psychiatric disorders were diagnosed in 19 (70.4%) subjects. These were most commonly depressive disorders (55.5%). Very few individuals were receiving treatment for their disorders. Substance abuse disorders were uncommon but a substantial proportion of individuals had problems with alcohol or drug misuse. Personality disorders were present in 29.6% of subjects and disorders or personality trait accentuation in 55.6%. Comorbidity of psychiatric disorders was found in a third of subjects. The suicides were often the end-point of long-term difficulties extending back to childhood or early adolescence. In addition to mental disorders, relationship and legal difficulties were identified as relatively common contributory factors to the suicides. In comparison to deliberate self-harm patients, male suicides were more likely to use dangerous methods and live alone. LIMITATIONS: Several potential informants could not be interviewed and there was no general population control sample. CONCLUSIONS: The process leading to suicide in young people is often long term, with untreated depression in the context of personality and/or relationship difficulties being a common picture at the time of death. The prevention of suicide in the young clearly requires multiple strategies.

The influence of the economic and social environment on deliberate self-harm and suicide: an ecological and person-based study.

BACKGROUND: Geographic variations in the incidence of deliberate self-harm (DSH) and suicide have been shown to be associated with area-based measures of socio-economic deprivation and social fragmentation. Previous studies have been subject to methodological limitations. None has investigated whether ecological associations are reflected in characteristics of individuals involved in suicidal behaviour. METHODS: DSH patients presenting to a general hospital between 1985 and 1995 and suicides (including open verdicts) from the same catchment area were studied. Mean annual rates of DSH and suicide by gender were calculated for electoral wards. The wards were amalgamated into 20 groups according to their ranking for socio-economic deprivation (Townsend) and social fragmentation scores. Associations of these variables with DSH and suicide rates were investigated. Characteristics of DSH patients living in ward groups with the highest and lowest socio-economic deprivation and social fragmentation scores were compared. RESULTS: Socio-economic deprivation was associated with DSH rates among males (r = 0.89) and females (r = 0.87). After controlling for social fragmentation the associations remained relatively strong, particularly in young males. Associations with social fragmentation in both genders (males, r = 0.83; females, r = 0.86) were attenuated after controlling for socio-economic deprivation. For suicide, the only significant association was with socio-economic deprivation in males (r = 0.79), but this was attenuated after controlling for social fragmentation. The characteristics of individual DSH patients reflected those of the areas where they lived. CONCLUSIONS: Reducing socio-economic deprivation and its associated problems may be an important strategy in the prevention of suicidal behaviour, especially in young men.

The efficacy of problem-solving treatments after deliberate self-harm: meta-analysis of randomized controlled trials with respect to depression, hopelessness and improvement in problems.

BACKGROUND: Brief problem-solving therapy is regarded as a pragmatic treatment for deliberate self-harm (DSH) patients. A recent meta-analysis of randomized controlled trials (RCTs) evaluating this approach indicated a trend towards reduced repetition of DSH but the pooled odds ratio was not statistically significant. We have now examined other important outcomes using this procedure, namely depression, hopelessness and improvement in problems. METHOD: Six trials in which problem-solving therapy was compared with control treatment were identified from an extensive literature review of RCTs of treatments for DSH patients. Data concerning depression, hopelessness and improvement in problems were extracted. Where relevant statistical data (e.g. standard deviations) were missing these were imputed using various statistical methods. Results were pooled using meta-analytical procedures. RESULTS: At follow-up, patients who were offered problem-solving therapy had significantly greater improvement in scores for depression (standardized mean difference = -0.36; 95% CI -0.61 to -0.11) and hopelessness (weighted mean difference =-3.2; 95% CI -4.0 to -2.41), and significantly more reported improvement in their problems (odds ratio = 2.31; 95% CI 1.29 to 4.13), than patients who were in the control treatment groups. CONCLUSIONS: Problem-solving therapy for DSH patients appears to produce better results than control treatment with regard to improvement in depression, hopelessness and problems. It is desirable that this finding is confirmed in a large trial, which will also allow adequate testing of the impact of this treatment on repetition of DSH.

Outcome of women admitted to hospital for depressive illness: factors in the prognosis of severe depression.

BACKGROUND: A previous study of women 9 months after discharge from in-patient treatment for depression found that low self-esteem as measured by a self-report questionnaire at admission was associated with a worse prognosis. This study investigates the womens' outcome more than 4 years after discharge and the continued prognostic relevance of self-esteem and other variables. METHOD: Fifty-six women who had been admitted to hospital with major depression and studied in detail during their admission and 9 months following discharge were traced 4-5 years later. Possible prognostic factors were investigated in relation to time to recovery and recurrence, and to a global outcome measure. RESULTS: In keeping with other published work only 16 out of 52 (31%) women had recovered and remained well. Fifteen out of 52 (29%) subjects had experienced depressive symptoms for more than 70% of the follow-up time or died from unnatural causes. Low self-esteem scores recorded at the initial admission correlated with slow recovery but not subsequent recurrence of depression. The occurrence of one or more life events in the year preceding admission was associated with a better prognosis. CONCLUSIONS: The poor long-term prognosis of many women with severe depression was confirmed. Social factors, such as social support and marital relationships were less important for prognosis than in previous studies of less severely ill subjects. The prognostic value of self-esteem warrants further investigation and appears to have therapeutic implications.

Deliberate self-harm patients with alcohol disorders: characteristics, treatment, and outcome.

Deliberate self-harm (DSH) patients with alcohol problems present a considerable challenge for clinical services. In a study of a sample of 150 DSH patients who were representative of all such patients seen at a general hospital during the study period, 40 patients with an ICD-10 diagnosis of alcohol dependence or harmful use of alcohol were compared with the remainder of the sample. The treatment of the patients with alcohol disorders before and after the episode of DSH and the outcome 12-20 months later were also investigated. Compared with other DSH patients, those with an alcohol diagnosis were older and more often male, living alone, unemployed, sick, disabled, or with a past history of DSH. They also had higher scores on measures of anger, aggression, and impulsivity. Comorbid psychiatric disorder was present in 37 (92.5%) patients, this being depression in three-quarters of those cases. Fourteen (35.0%) patients were receiving treatment from the psychiatric services prior to DSH, and 33 (82.5%) were subsequently offered treatment. Of the patients who were followed up, 37.9% remained in contact with psychiatric services, 55.2% showed poor compliance with treatment and 44.8% reported a further episode of DSH. All patients presenting after DSH need to be carefully screened for alcohol disorders and for comorbid psychiatric diagnoses. Treatment of DSH patients with alcohol disorders should include the treatment of any comorbid depressive illness.

Suicide in doctors: a study of risk according to gender, seniority and specialty in medical practitioners in England and Wales, 1979-1995.

STUDY OBJECTIVE: To investigate the suicide risk of doctors in England and Wales, according to gender, seniority and specialty. DESIGN: Retrospective cohort study. Suicide rates calculated by gender, age, specialty, seniority and time period. Standardised mortality ratios calculated for suicide (1991-1995), adjusted for age and sex. SETTING: England and Wales. SUBJECTS: Doctors in the National Health Service who died by suicide between 1979 and 1995, identified by death certificates. Population at risk based on Department of Health manpower data. MAIN RESULTS: Two hundred and twenty three medical practitioners in the National Health Service who died by suicide or undetermined cause were identified. The annual suicide rates in male and female doctors were 19.2 and 18.8 per 100 000 respectively. The suicide rate in female doctors was higher than in the general population (SMR 201.8; 95% CI 99.7, 303.9), whereas the rate in male doctors was less than that of the general population (SMR 66.8; 95% CI 46.6, 87.0). The difference between the mortality ratios of the female and male doctors was statistically significant (p=0.01), although the absolute suicide risk was similar in the two genders. There were significant differences between specialties (p=0.0001), with anaesthetists, community health doctors, general practitioners and psychiatrists having significantly increased rates compared with doctors in general hospital medicine. There were no differences with regard to seniority and time period. CONCLUSIONS: There is an increased risk of suicide in female doctors, but male doctors seem to be at less risk than men in the general population. The excess risk of suicide in female doctors highlights the need to tackle stress and mental health problems in doctors more effectively. The risk requires particular monitoring in the light of the very large increase in the numbers of women entering medicine.

Psychiatric and personality disorders in deliberate self-harm patients.

BACKGROUND: Previous UK studies have reported much lower rates of psychiatric and personality disorder in those who attempt suicide than in those who die by suicide. AIMS: To determine the nature and prevalence of psychiatric and personality disorders in deliberate self-harm (DSH) patients. METHOD: A representative sample of 150 DSH patients who presented to a general hospital were assessed using a structured clinical interview and a standardised instrument. Follow-up interviews were completed for 118 patients approximately 12-16 months later. RESULTS: ICD-10 psychiatric disorders were diagnosed in 138 patients (92.0%), with comorbidity of psychiatric disorders in 46.7%. The most common diagnosis was affective disorder (72.0%). Personality disorder was identified in 45.9% of patients interviewed at follow-up. Comorbidity of psychiatric and personality disorder was present in 44.1%. CONCLUSIONS: Psychiatric and personality disorders, and their comorbidity, are common in DSH patients. This has important implications for assessment and management.

Psychosocial and pharmacological treatment of patients following deliberate self-harm: the methodological issues involved in evaluating effectiveness.

Development of effective treatments for patients following deliberate self-harm (self-poisoning or self-injury) is a very important element in suicide prevention. The randomized controlled trial (RCT) is the mainstay of evaluation of treatments. In a systematic review of the literature, the effectiveness of treatments based on RCTs was examined and the quality of the RCTs was assessed. Twenty trials were identified, and where possible, these were grouped on the basis of similarities among the types of treatment. In this paper, we examine the methodological aspects of the trials and consider what may be learned that will assist in the design of future studies in this field. The methodological quality of the trials was reasonable, but most trials included too few participants to detect clinically important differences in rates of repeated self-harm. In planning future trials, the following major issues should be addressed: investigators should perform power calculations to determine the number of subjects necessary to detect clinically important effects, provide information on method of randomization and interventions, use standard measures of outcome, and focus on homogeneous subgroups of patients. Improving the methodology of future studies in this field will be essential if sound evidence is to be obtained which can inform effective service provision for deliberate self-harm patients.

Studying survivors of nearly lethal suicide attempts: an important strategy in suicide research.

The series of articles in this special issue of SLTB from the Centers for Disease Control and Prevention (CDC) study of nearly lethal suicide attempts represents an important contribution to research on suicidal behavior. The investigative approach used is attractive, yet also challenging in terms of research methodology. In this commentary I take the opportunity to highlight certain aspects of this line of research as well as to comment on the specific findings of the CDC study and their relationship to existing knowledge. I also discuss the future potential for this research approach and further questions that might be addressed by it.

Suicide in older people: mode of death, demographic factors, and medical contact before death.

OBJECTIVE: To determine the demographic characteristics, mode of death, and nature and timing of medical contacts in the year before death in a sample of suicides in older people. DESIGN: Descriptive study of a case series of 195 suicides in older people. SETTING: Four counties and one large urban area in central England, UK. SUBJECTS: Individuals 60 years old and over at time of death, who had died between 1 January 1995 and 1 May 1998, and whose deaths has received a coroner's verdict of suicide, or an open or accidental verdict where the circumstances of death indicated probable suicide. MAIN OUTCOME MEASUREMENTS: Demographic details and information on mode of death and medical contact prior to death derived from coroners' inquest notes, General Practitioners' (GP) case-notes and psychiatric records. MAIN RESULTS: 67.7% were male. A higher proportion of men than women were single or divorced. The commonest methods of suicide were hanging in men and drug overdose in women, 49.8% had seen their GP in the month before death, although over half these last consultations were for physical complaints. Only 15.4% were under psychiatric care at the time of death. CONCLUSIONS: Older men are at higher risk of suicide than women. Given the high proportion of drug overdoses in the sample, effective strategies to prevent suicide in older people might include improving the prescribing of analgesics and antidepressants. Although older people at risk of suicide often consult their GP shortly before death, GPs may have difficulty identifying those at risk because of the high proportion of physical complaints.

Psychosocial versus pharmacological treatments for deliberate self harm.

OBJECTIVES: To identify and synthesise the findings from all randomised controlled trials that have examined the effectiveness of treatments of patients who have deliberately harmed themselves. SEARCH STRATEGY: Electronic databases screened: MEDLINE (from 1966-February 1999); PsycLit (from 1974-March 1999); Embase (from 1980-January 1999); The Cochrane Controlled Trials Register (CCTR) No.1 1999. Ten journals in the field of psychiatry and psychology were hand searched for the first version of this review. We have updated the hand search of three specialist journals in the field of suicidal research until the end of 1998. Reference lists of papers were checked and trialists contacted. SELECTION CRITERIA: All RCTs of psychosocial and/or psychopharmacological treatment versus standard or less intensive types of aftercare for patients who shortly before entering a study engaged in any type of deliberately initiated self-poisoning or self-injury, both of which are generally subsumed under the term deliberate self-harm. DATA COLLECTION AND ANALYSIS: Data were extracted from the original reports independently by two reviewers. Studies were categorized according to type of treatment. The outcome measure used to assess the efficacy of treatment interventions for deliberate self-harm was the rate of repeated suicidal behaviour. We have been unable to examine other outcome measures as originally planned (e.g. compliance with treatment, depression, hopelessness, suicidal ideation/thoughts, change in problems/problem resolution). MAIN RESULTS: A total of 23 trials were identified in which repetition of deliberate self-harm was reported as an outcome variable. The trials were classified into 11 categories. The summary odds ratio indicated a trend towards reduced repetition of deliberate self-harm for problem-solving therapy compared with standard aftercare (0.70; 0.45 to 1.11) and for provision of an emergency contact card in addition to standard care compared with standard aftercare alone (0.45; 0.19 to 1.07). The summary odds ratio for trials of intensive aftercare plus outreach compared with standard aftercare was 0.83 (0.61 to 1.14), and for antidepressant treatment compared with placebo was 0.83 (0. 47 to 1.48). The remainder of the comparisons were in single small trials. Significantly reduced rates of further self-harm were observed for depot flupenthixol vs. placebo in multiple repeaters (0. 09; 0.02 to 0.50), and for dialectical behaviour therapy vs. standard aftercare (0.24; 0.06 to 0.93). REVIEWER'S CONCLUSIONS: There still remains considerable uncertainty about which forms of psychosocial and physical treatments of self-harm patients are most effective, inclusion of insufficient numbers of patients in trials being the main limiting factor. There is a need for larger trials of treatments associated with trends towards reduced rates of repetition of deliberate self-harm. The results of small single trials which have been associated with statistically significant reductions in repetition must be interpreted with caution and it is desirable that such trials are also replicated.

Deliberate self-harm in adolescents in Oxford, 1985-1995.

Deliberate self-harm (DSH) has been one of the major health problems of adolescents in the U.K. for many years. Any changes in rates of DSH or the demographic characteristics of the patient population are likely to have important implications for clinical services and for future suicidal behaviour. Following a decline in rates in the late 1970s and mid 1980s, there were signs in the late 1980s that rates were beginning to increase again. We have used data collected by the Oxford Monitoring System for Attempted Suicide on the basis of patients presenting to the general hospital in Oxford to review trends in DSH in under 20-year-olds between 1985 and 1995. There was a substantial increase in the numbers of teenage DSH patients during the 11-year study period, with an increase between 1985-1986 and 1994-1995 of 27.7% in males, 28.3% in females, and 28.1% overall. There were no demographic changes within the catchment area to explain a change of this size. As rates of repetition of DSH also increased in both sexes during the study period the overall number of episodes of DSH rose even more between 1985-1986 and 1994-1995 (+56.9% in males, +46.3% in females, and +49.4% overall). As in previous studies the majority of adolescents had interpersonal problems and/or difficulties with studying or employment. Self-poisoning with paracetamol and paracetamol compounds became increasingly common such that by 1995 these were used in almost two-thirds of overdoses. The recent increase in DSH in adolescents has important implications for general hospital and adolescent psychiatric services. The greater frequency of repetition of DSH may herald increased future suicide rates. The case for restricting the amount of paracetamol available is overwhelming. Evaluative trials of specific interventions following adolescent DSH are urgently required.

Recommended care for young people (15-19 years) after suicide attempts in certain European countries.

Data on recommended care for young people aged 15-19 years after attempted suicide from nine European research centres during the period 1989-1992 were analysed in terms of gender, history of previous suicide attempt and methods used. Altogether 438 suicide attempts made by 353 boys and 1,102 suicide attempts made by 941 girls were included. Analyses of the total data from all centres showed that young people with a history of previous suicide attempt and those using violent methods had significantly higher chance of being recommended aftercare than first-time attempters or those choosing self-poisoning. There were no significant differences of being recommended care between genders. Logistic regression analyses of the material were performed and the results were similar. Both having previous attempted suicide (odds ratio 2.0, 95% CI 1.53-2.61) and using "hard" methods (odds ratio 1.71, 95% CI 1.49-1.96) were significantly associated with increased possibility of being recommended aftercare. When individual centres were analysed, large disparities of recommended care after suicide attempts were found and there were no uniform criteria of recommending care for young suicide attempters in Europe.

Methods used for parasuicide: results of the WHO/EURO Multicentre Study on Parasuicide.

BACKGROUND: National suicide statistics show remarkable differences in the frequencies of various methods used for completed suicide. The WHO/EURO Multicentre Study on Parasuicide makes possible for the first time an international comparison of the frequencies of methods used in attempted suicide, because the data are based on geographical catchment areas of medical institutions. METHOD: Ongoing standardized monitoring of attempted suicide in all medical institutions serving the catchment areas was performed in 14 centres in 12 European countries. The data analysis is based on 20,649 events involving 15,530 persons, recorded between 1989 and 1993. RESULTS: The comparison of rates per 100,000 shows striking differences between the centres. The highest rates for drug overdoses were found for female attempters in Oxford (347/100,000), Helsinki (238/100,000) and Stockholm (221/100,000). Guipuzcoa had the lowest rates (61/100,000). The differences were most prominent in the age group 15-24, with outstanding rates for women in Oxford (653/100,000), which was mainly due to the frequent use of analgesics. Szeged had outstandingly high rates for pesticides and solvents. In some centres the use of multiple methods was frequent. CONCLUSIONS: There is a need, especially for areas with high frequencies for certain methods, to understand the factors involved and to develop new and specific prevention projects and to monitor their effects. The WHO/EURO Multicentre Study on Parasuicide has proved to be a useful and reliable instrument for continuous monitoring of trends in parasuicide.

Deliberate self poisoning with antidepressant drugs: a comparison of the relative hospital costs of cases of overdose of tricyclics with those of selective-serotonin re-uptake inhibitors.

BACKGROUND: Debate continues over the relative merits of tricyclics and selective serotonin re-uptake inhibitors (SSRIs) as first line antidepressant treatment for depression. SSRIs are safer in overdose but more expensive than tricyclics. This report compared the hospital costs of cases of overdose with both groups of drug. METHODS: Records of all persons aged over thirteen years presenting to a general hospital in one year were analysed for demographic information and details of their attendance. RESULTS: There were 1165 episodes of self-poisoning, 151 involving tricyclics as the sole antidepressant and 69 SSRIs as the sole antidepressant. Those taking SSRIs had a shorter (1.96 vs. 2.59 days) and less expensive ( pound330 vs. pound567) stay. A large proportion of this difference in cost was due to a small number of admissions to the Intensive Care Unit. LIMITATIONS: This study used only hospital costs, so excluding costs associated with primary care. CONCLUSIONS AND CLINICAL RELEVANCE: If there were similar cost differences countrywide, the difference in hospital costs of self poisoning with SSRIs and tricyclics would represent an additional pound3.87 million per year due to self poisoning with tricyclics across the whole of England and Wales. This is a small proportion of the estimated pound100 million cost of switching to first-line prescribing of SSRIs for depression.

Doctors who kill themselves: a study of the methods used for suicide.

Medical practitioners have a relatively high rate of suicide. Death entry data for doctors who died by suicide or undetermined cause between 1979 and 1995 in England and Wales were used to compare methods used for suicide by doctors with those used by the general population. Methods used were analysed according to gender, occupational status and speciality, to assess the extent to which access to dangerous means influences the pattern of suicide. Self-poisoning with drugs was more common in the doctors than in general population suicides (57% vs. 26.6%; OR=3.65, 95% CI 2.85-4. 68), including in retired doctors. Barbiturates were the most frequent drugs used. Half of the anaesthetists who died used anaesthetic agents. Self-cutting was also more frequently used as a method of suicide. The finding that the greater proportion of suicide deaths in doctors were by self-poisoning may reflect the fact that doctors have ready access to drugs, and have knowledge of which drugs and doses are likely to cause death. The specific finding that a large proportion of suicides in anaesthetists involved anaesthetic agents supports this explanation. Availability of method may be a factor contributing to the relatively high suicide rate of doctors. This fact might influence clinical management of doctors who are known to be depressed or suicidal.

Suicide in psychiatric hospital in-patients. Risk factors and their predictive power.

BACKGROUND: Psychiatric hospital in-patients are known to be at high risk of suicide, yet there is little reliable knowledge of risk factors or their predictive power. AIMS: To identify risk factors for suicide in psychiatric hospital in-patients and to evaluate their predictive power in detecting people at risk of suicide. METHOD: Using a case-control design, 112 people who committed suicide while in-patients in psychiatric hospitals were compared with 112 randomly selected controls. Univariate analysis and multivariate analyses were used to estimate odds ratios and adjusted likelihood ratios. RESULTS: The rate of suicide in psychiatric in-patients was 13.7 (95% CI 11.7-16.1) per 10,000 admissions. There were five predictive factors with likelihood ratios > 2, following adjustment: planned suicide attempt, 4.1; actual suicide attempt, 4.9; recent bereavement, 4.0; presence of delusions, 2.3; chronic mental illness, 2.2; and family history of suicide, 4.6. On this basis, only two of the patients who committed suicide had a predicted risk of suicide above 5%. CONCLUSIONS: Although several factors were identified that were strongly associated with suicide, their clinical utility is limited by low sensitivity and specificity, combined with the rarity of suicide, even in this high-risk group.
