Background: Suicide prevention is a health service priority. Homeless mental health patients present a challenge to services because of their complex health and social needs., Aims: To establish the numbers of homeless patients in contact with services who die by suicide; to describe their suicide methods and their social and clinical characteristics including aspects of clinical care., Method: A national clinical survey based on a 4-year (1996-2000) sample of people in England and Wales who died by suicide. Detailed data were collected on those who had been in contact with mental health services in the year before death., Results: A total of 131 individuals who died by suicide were reported to have been homeless at the time of death--3% of all suicides by psychiatric patients, over 30 per year. Hanging was the most common cause of death. The most frequent diagnosis was schizophrenia. Around half were in-patients at the time of death. Social and clinical risk factors for suicide were common, including drug and alcohol misuse, and recent suicidal ideas and behaviour. Despite this, their clinical care was characterised by disengagement from services as a result of missed contacts, self-discharge, lack of follow-up and lack of key worker., Conclusions: In order to reduce the number of deaths by suicide in those who are homeless and mentally ill, improvements in in-patient safety and engagement in the community are needed. This may be achieved through assertive community treatment, dual diagnosis services, and dedicated community mental health teams.

Background: Suicide prevention is a health service priority. Suicide risk may be greatest during psychiatric in-patient admission and following discharge., Aims: To describe the social and clinical characteristics of a comprehensive sample of in-patient and post-discharge cases of suicide., Method: A national clinical survey based on a 4-year (1996-2000) sample of cases of suicide in England and Wales who had been in recent contact with mental health services (n=4859)., Results: There were 754 (16%) current in-patients and a further 1100 (23%) had been discharged from psychiatric in-patient care less than 3 months before death. Nearly a quarter of the in-patient deaths occurred within the first 7 days of admission; 236 (31%) occurred on the ward, the majority by hanging. Post-discharge suicide was most frequent in the first 2 weeks after leaving hospital; the highest number occurred on the first day., Conclusions: Suicide might be prevented among in-patients by improving ward design and removing fixtures that can be used in hanging. Prevention of suicide after discharge requires early community follow-up and closer supervision of high-risk patients.

Background: There have been few studies of the most serious cases of deliberate self-harm (DSH). These cases represent an important clinical problem. They may also be suitable as a "proxy" for suicide in research studies., Methods: We developed a definition of "near-fatal" deliberate self-harm (NFDSH) and identified all cases attending accident and emergency departments in an urban area during an 18-month period. We compared them to less severe DSH on social and clinical characteristics, and examined their initial clinical management. We compared their age and gender profile with that of completed suicides. NFDSH cases who agreed to be interviewed were asked about their experiences of seeking help and their views on prevention of suicide., Results: 158 cases were identified, 8% of all DSH. The most common method of self-harm was self-poisoning. The most common psychiatric diagnosis was depression. Compared to less severe DSH, near-fatal cases had higher rates of several social and clinical risk factors for suicide and showed evidence of greater suicidal intent. Forty-one percent were allowed home following assessment. Most admissions lasted 2 days or less. The age and gender profile was closer to that of suicide than in DSH generally. Few subjects agreed to be interviewed; those who did described poor previous experiences of services., Limitations: We did not assess each case of DSH individually but applied a workable definition of NFDSH. Firm conclusions cannot be drawn from the qualitative part of the study because of the low rate of agreement to interview., Conclusions: NFDSH is an important clinical phenomenon associated with indicators of high suicide risk. This high risk is frequently not reflected in clinical management. Further studies of NFDSH could contribute to what is known about suicide prevention but the reluctance of NFDSH subjects to be interviewed may be a difficulty for future research.

Background: Life events are often reported to precede suicide. This paper aims to determine the frequency, timing and type of life events preceding suicide by young people and those with and without a mental illness., Method: Informants, usually family members, were interviewed for a sample of young (less than 35 years) suicides. Information was recorded on events occurring in the 6 months before death. Equivalent information was obtained for living controls who had been matched for age and gender and obtained through the general practices of the suicides., Results: Suicide was associated with life events in the previous 3 months, and particularly in the previous week. Specifically, interpersonal and forensic (being arrested, charged or sentenced) events distinguished suicides and controls. The number of life events in the different time periods under study did not distinguish suicides with and without severe mental illness, although more suicides without a severe mental illness had a reported life event in the week before their death., Conclusions: Adverse life events frequently precede suicide in young people with and without severe mental illness. However, recent life events may have a lesser causal role in those with severe mental illness. Clinical and health promotion measures to improve the way that young people cope with interpersonal problems and other crises may be an important part of any suicide prevention strategy.

Background: Self-asphyxiation using car exhaust gas is a common method of suicide in England and Wales, particularly in young males. The introduction of catalytic converters has reduced the toxicity of car exhausts. The main aims of the study were: to seek evidence of a fall in car exhaust suicides in the general population and in age and gender groups; to relate any fall to changes in car exhaust systems, particularly since legislation on car exhaust emissions in 1993; and to examine rates of suicide by other methods for evidence of method substitution., Methods: Population study in England and Wales using national suicide statistics for 1987 to 1998., Results: There was a fall in suicide by car exhaust asphyxiation in all age and gender groups. This change was most marked after 1993. The overall population suicide rate (all methods) also fell but there was no overall change in suicides by young males or females. In these groups suicide by hanging increased., Conclusions: Legislation on catalytic converters appears to have contributed to a fall in car exhaust suicides. However, the effect on overall suicide rates in young people has been reduced by method substitution.

Background: The death of the Princess of Wales in 1997 was followed by widespread public mourning. Such major events may influence suicidal behaviour., Aims: To assess the impact of the Princess's death on suicide and deliberate self-harm (DSH)., Method: Analysis, using Poisson regression, of the number of suicides and open verdicts ('suicides') in England and Wales following the Princess's death compared to the 3 months beforehand, and the equivalent periods in 1992-1996. Similar analysis on DSH presentations to a general hospital., Results: Suicides increased during the month following the Princess's funeral (+17.4%). This was particularly marked in females (+33.7%), especially those aged 25-44 years (+45.1%). Suicides did not fall in the week between the death and the funeral. Presentations for DSH increased significantly during the week following the death (+44.3%), especially in females (+65.1%). Examination of case notes suggested that the influence of the death was largely through amplification of personal losses or exacerbation of existing distress., Conclusions: The death of a major public figure can influence rates of suicidal behaviour. For DSH, the impact may be immediate, but for suicide it may be delayed.

Background: In the past two decades the suicide rate in young people has risen in the UK and other countries., Aims: To identify the characteristics of people aged under 35 who commit suicide., Method: Psychological autopsy study with case-control design. Cases were 84 suicides and probable suicides (open verdicts). Controls were 64 age- and gender-matched non-suicides obtained through the general practices of the matched cases., Main Variables: social, including employment status, marital status and living circumstances; life events and interpersonal difficulties; clinical, including current psychiatric disorder, alcohol and drug misuse, previous self-harm and personality disorder., Results: A large number of highly significant social, interpersonal and clinical differences between suicides and controls was found. Factor analysis identified two groups of variables within each of the social, interpersonal and clinical domains which were independently linked to suicide, corresponding to: acute, severe mental disorder and chronic disorder of behaviour; rootlessness and social withdrawal; chronic and recent interpersonal problems., Conclusions: A broad prevention strategy is needed to reverse the recent rise in the suicide rate in young people.

Objective: To describe the clinical circumstances in which psychiatric patients commit suicide., Design: National clinical survey., Setting: England and Wales., Subjects: A two year sample of people who had committed suicide, in particular those who had been in contact with mental health services in the 12 months before death., Main Outcome Measures: Proportion of suicides in people who had had recent contact with mental health services; proportion of suicides in inpatients; proportion of people committing suicide and timing of suicide within three months of hospital discharge; proportion receiving high priority under the care programme approach; proportion who were recently non-compliant and not attending., Results: 10 040 suicides were notified to the study between April 1996 and March 1998, of whom 2370 (24%; 95% confidence interval 23% to 24%) had had contact with mental health services in the year before death. Data were obtained on 2177, a response rate of 92%. In general these subjects had broad social and clinical needs. Alcohol and drug misuse were common. 358 (16%; 15% to 18%) were psychiatric inpatients at the time of death, 21% (17% to 25%) of whom were under special observation. Difficulties in observing patients because of ward design and nursing shortages were both reported in around a quarter of inpatient suicides. 519 (24%; 22% to 26%) suicides occurred within three months of hospital discharge, the highest number occurring in the first week after discharge. 914 (43%; 40% to 44%) were in the highest priority category for community care. 488 (26% excluding people whose compliance was unknown; 24% to 28%) were non-compliant with drug treatment while 486 (28%; 26% to 30%) community patients had lost contact with services. Most people who committed suicide were thought to have been at no or low immediate risk at the final service contact. Mental health teams believed suicide could have been prevented in 423 (22%; 20% to 24%) cases., Conclusions: Several suicide prevention measures in mental health services are implied by these findings, including measures to improve compliance and prevent loss of contact with services. Inpatient facilities should remove structural difficulties in observing patients and fixtures that can be used in hanging. Prevention of suicide after discharge may require earlier follow up in the community. Better suicide prevention in psychiatric patients is likely to need measures to improve the safety of mental health services as a whole, rather than specific measures for people known to be at high risk.

Background: The suicide rate in young men, but not young women, is rising. One possible route to suicide prevention is through general practice but recent evidence suggests that young suicides are not likely to attend GP surgeries prior to death., Method: We carried out a retrospective examination of general practice contacts by a 2-year sample of suicides under 35 years of age in the 12 health districts of Greater Manchester. In the 61 young suicides who were known to attend a GP in the three months before death, we recorded (a) the number of consultations each week in the three months before suicide; (b) sex differences in rates of and reasons for consultation; (c) frequency of recorded risk assessment at the last GP visit before suicide., Results: The number of GP visits increased significantly before death. A monthly increase was more evident in males, but the increase in the week before death was more marked in females. There was no sex difference in the rate of GP visits before suicide; both sexes were most likely to attend for psychological reasons. Significant suicide risk had been noted at none of the final GP visits., Conclusions: There remains a potential role for GPs in preventing suicides by young people of both sexes. The recent increase in suicide by young males does not appear to be related to a lower rate of GP attendance before death. Future training of GPs in this area should focus on risk assessment.
