Contacts with primary and secondary healthcare before suicide by those under the care of mental health services: case-control, whole-population-based study using person-level linked routine data in Wales, UK during 2000-2015.

BACKGROUND: People under the care of mental health services are at increased risk of suicide. Existing studies are small in scale and lack comparisons. AIMS: To identify opportunities for suicide prevention and underpinning data enhancement in people with recent contact with mental health services. METHOD: This population-based study includes people who died by suicide in the year following a mental health services contact in Wales, 2001-2015 (cases), paired with similar patients who did not die by suicide (controls). We linked the National Confidential Inquiry into Suicide and Safety in Mental Health and the Suicide Information Database - Cymru with primary and secondary healthcare records. We present results of conditional logistic regression. RESULTS: We matched 1031 cases with 5155 controls. In the year before their death, 98.3% of cases were in contact with healthcare services, and 28.5% presented with self-harm. Cases had more emergency department contacts (odds ratio 2.4, 95% CI 2.1-2.7) and emergency hospital admissions (odds ratio 1.5, 95% CI 1.4-1.7), but fewer primary care contacts (odds ratio 0.7, 95% CI 0.6-0.9) and out-patient appointments (odds ratio 0.2, 95% CI 0.2-0.3) than controls. Odds ratios were larger in females than males for injury and poisoning (odds ratio: 3.3 (95% CI 2.5-4.5) v. 2.6 (95% CI 2.1-3.1)). CONCLUSIONS: We may be missing existing opportunities to intervene, particularly in emergency departments and hospital admissions with self-harm presentations and with unattributed self-harm, especially in females. Prevention efforts should focus on strengthening routine care contacts, responding to emergency contacts and better self-harm care. There are benefits to enhancing clinical audit systems with routinely collected data.

Suicide after leaving the UK Armed Forces 1996-2018: A cohort study.

BACKGROUND: There are comparatively few international studies investigating suicide in military veterans and no recent UK-wide studies. This is important because the wider context of being a UK Armed Forces (UKAF) veteran has changed in recent years following a period of intensive operations. We aimed to investigate the rate, timing, and risk factors for suicide in personnel who left the UKAF over a 23-year period. METHODS AND FINDINGS: We carried out a retrospective cohort study of suicide in personnel who left the regular UKAF between 1996 and 2018 linking national databases of discharged personnel and suicide deaths, using survival analysis to examine the risk of suicide in veterans compared to the general population and conditional logistic regression to investigate factors most strongly associated with suicide after discharge. The 458,058 individuals who left the UKAF accumulated over 5,852,100 person years at risk, with a median length of follow-up of 13 years, were mostly male (91%), and had a median age of 26 years at discharge. 1,086 (0.2%) died by suicide. The overall rate of suicide in veterans was slightly lower than the general population (standardised mortality ratio, SMR [95% confidence interval, CI] 94 [88 to 99]). However, suicide risk was 2 to 3 times higher in male and female veterans aged under 25 years than in the same age groups in the general population (age-specific mortality ratios ranging from 160 to 409). Male veterans aged 35 years and older were at reduced risk of suicide (age-specific mortality ratios 47 to 80). Male sex, Army service, discharge between the ages of 16 and 34 years, being untrained on discharge, and length of service under 10 years were associated with higher suicide risk. Factors associated with reduced risk included being married, a higher rank, and deployment on combat operations. The rate of contact with specialist NHS mental health services (273/1,086, 25%) was lowest in the youngest age groups (10% for 16- to 19-year-olds; 23% for 20- to 24-year-olds). Study limitations include the fact that information on veterans was obtained from administrative databases and the role of pre-service vulnerabilities and other factors that may have influenced later suicide risk could not be explored. In addition, information on contact with support services was only available for veterans in contact with specialist NHS mental health services and not for those in contact with other health and social care services. CONCLUSIONS: In this study, we found suicide risk in personnel leaving the UKAF was not high but there are important differences according to age, with higher risk in young men and women. We found a number of factors which elevated the risk of suicide but deployment was associated with lower risk. The focus should be on improving and maintaining access to mental health care and social support for young service leavers, as well as implementing general suicide prevention measures for all veterans regardless of age.

Recent GP consultation before death by suicide in middle-aged males: a national consecutive case series study.

BACKGROUND: Reducing suicide risk in middle-aged males (40-54 years) is a national priority. People have often presented to their GP within 3 months before suicide thus highlighting an opportunity for early intervention. AIM: To describe the sociodemographic characteristics and identify antecedents in middle-aged males who recently consulted a GP before dying by suicide. DESIGN AND SETTING: This study was a descriptive examination of suicide in a national consecutive sample of middle-aged males in 2017 in England, Scotland, and Wales. METHOD: General population mortality data were obtained from the Office for National Statistics and National Records of Scotland. Information was collected about antecedents considered relevant to suicide from data sources. Logistic regression examined associations with final recent GP consultation. Males with lived experience were consulted during the study. RESULTS: In 2017, a quarter (n = 1516) of all suicide deaths were in middle-aged males. Data were attained on 242 males: 43% had their last GP consultation within 3 months of suicide; and a third of these males were unemployed and nearly half were living alone. Males who saw a GP recently before suicide were more likely to have had recent self-harm and work-related problems than males who had not. Having a current major physical illness, recent self-harm, presenting with a mental health problem, and recent work-related issues were associated with having a last GP consultation close to suicide. CONCLUSION: Clinical factors were identified that GPs should be alert to when assessing middle-aged males. Personalised holistic management may have a role in preventing suicide in these individuals.

Bereavement and suicide bereavement as an antecedent of suicide in children and young people: Prevalence and characteristics.

INTRODUCTION: There is limited research into bereavement and suicide bereavement as an antecedent of suicide in young people. METHODS: We extracted information on the antecedents of suicide from official reports, primarily coroner inquests, on a 3-year national consecutive case series of all UK deaths by suicide in people aged 10-19. RESULTS: Between 2014 and 2016, there were 595 suicides by young people. 134 (25%) had been previously or recently bereaved; 51 (9%) by suicide, mainly of a friend or acquaintance. This is equivalent to 1 in 4 and 1 in 11, respectively, of all young people who die by suicide. Bereavement added to existing adversities - many antecedents of suicide were more likely in young people who were bereaved compared to those who were not, but there were few differences in the experiences of young people bereaved by suicide compared to other causes. LIMITATIONS: This was an observational, not a risk factor study, and we did not use a control group. It is difficult to obtain data on non-suicide controls due to the ethical implications in contacting families, and the fact of suicide itself, its impact on disclosure and the reluctance of potential controls distorting any comparisons. CONCLUSION: Lasting bereavement support needs to be routinely and immediately available for young people, including those who have experienced the death of a friend or acquaintance. Vigilance of agencies for bereaved young people is required, especially if there is evidence of other adversities.

Suicide in England in the COVID-19 pandemic: Early observational data from real time surveillance.

BACKGROUND: There have been concerns that the COVID-19 pandemic may lead to an increase in suicide. The coronial system in England is not suitable for timely monitoring of suicide because of the delay of several months before inquests are held. METHODS: We used data from established systems of "real time surveillance" (RTS) of suspected suicides, in areas covering a total population of around 13 million, to test the hypothesis that the suicide rate rose after the first national lockdown began in England. FINDINGS: The number of suicides in April-October 2020, after the first lockdown began, was 121•3 per month, compared to 125•7 per month in January-March 2020 (-4%; 95% CI-19% to 13%, p = 0•59). Incidence rate ratios did not show a significant rise in individual months after lockdown began and were not raised during the 2-month lockdown period April-May 2020 (IRR: 1•01 [0•81-1•25]) or the 5-month period after the easing of lockdown, June-October 2020 (0•94 [0•81-1•09]). Comparison of the suicide rates after lockdown began in 2020 for the same months in selected areas in 2019 showed no difference. INTERPRETATION: We did not find a rise in suicide rates in England in the months after the first national lockdown began in 2020, despite evidence of greater distress. However, a number of caveats apply. These are early figures and may change. Any effect of the pandemic may vary by population group or geographical area. The use of RTS in this way is new and further development is needed before it can provide full national data. FUNDING: This study was funded by the Healthcare Quality Improvement Partnership (HQIP).The HQIP is led by a consortium of the Academy of Medical Royal Colleges, the Royal College of Nursing, and National Voices. Its aim is to promote quality improvement in patient outcomes, and in particular, to increase the impact that clinical audit, outcome review programs and registries have on healthcare quality in England and Wales. HQIP holds the contract to commission, manage, and develop the National Clinical Audit and Patient Outcomes Program (NCAPOP), comprising around 40 projects covering care provided to people with a wide range of medical, surgical and mental health conditions. The program is funded by NHS England, the Welsh Government and, with some individual projects, other devolved administrations, and crown dependencies.

Evaluating the impact of patient and carer involvement in suicide and self-harm research: A mixed-methods, longitudinal study protocol.

BACKGROUND: Patient and public involvement (PPI) is becoming more commonplace in mental health research. There are strong moral and ethical arguments for good quality PPI. Few studies have documented and evaluated PPI in self-harm and suicide research. Inconsistent reporting of PPI makes it difficult to discern practices that deliver quality, effective and meaningful involvement. It is important to understand and address emotional support needs of PPI members contributing to sensitive topics such as suicide and self-harm. Therefore, this study will examine the effect of PPI on self-harm and suicide research and explore patients', carers' and researchers' experiences and views in relation to the quality of PPI practice and provision of appropriate support for PPI members. METHODS: This protocol outlines the longitudinal, mixed methodological approach that will be taken. Qualitative and quantitative data will be collected via baseline and repeated questionnaires, document review and semi-structured interviews. Both PPI members and researchers will be invited to participate in this study. The two-year data collection period will enable evaluation of PPI throughout the entire research cycle. An integrated approach will be taken to data analysis, using inductive thematic analysis and descriptive and repeated measures analyses, to address specified study aims. DISSEMINATION: Findings from this study will inform practical guidance to support self-harm and suicide researchers in effectively involving people with experiential knowledge in their research. Analyses will offer insight into the effect of PPI throughout the research process and assess changes in PPI members' and researchers' experiences of involvement across a two-year period.

Suicide risk assessment in UK mental health services: a national mixed-methods study.

BACKGROUND: Risk assessments are a central component of mental health care. Few national studies have been done in the UK on risk assessment tools used in mental health services. We aimed to examine which suicide risk assessment tools are in use in the UK; establish the views of clinicians, carers, and service users on the use of these tools; and identify how risk assessment tools have been used with mental health patients before suicide. METHODS: We did a mixed-methods study involving three components: collection and content analysis of risk assessment tools used by UK mental health services; an online survey of clinicians, service-users, and carers; and qualitative telephone interviews with clinicians on their use of risk assessment tools before a suicide death and their views of these tools. The online survey was advertised through the National Confidential Inquiry into Suicide and Safety in Mental Health's (NCISH) website and social media, and it included both quantitative and open-ended qualitative questions, and respondents were recruited through convenience sampling. For the telephone interviews, we examined the NCISH database to identify clinicians who had been responsible for the care of a patient who died by suicide and who had been viewed as being at low or no immediate risk of suicide. FINDINGS: We obtained 156 risk assessment tools from all 85 National Health Service mental health organisations in the UK, and 85 (one per each organisation) were included in the analysis. We found little consistency in use of these instruments, with 33 (39%) of 85 organisations using locally developed tools. Most tools aimed to predict self-harm or suicidal behaviour (84 [99%] of 85), and scores were used to determine management decisions (80 [94%]). Clinicians described positive aspects of risk tools (facilitating communication and enhancing therapeutic relationships) but also expressed negative views (inadequate training in the use of tools and their time-consuming nature). Both patients and carers reported some positive views, but also emphasised little involvement during risk assessment, and a lack of clarity on what to do in a crisis. INTERPRETATION: Assessment processes need to be consistent across mental health services and include adequate training on how to assess, formulate, and manage suicide risk. An emphasis on patient and carer involvement is needed. In line with national guidance, risk assessment should not be seen as a way to predict future behaviour and should not be used as a means of allocating treatment. Management plans should be personalised and collaboratively developed with patients and their families and carers. FUNDING: The Healthcare Quality Improvement Partnership.

Suicide in children and young people: Can it happen without warning?

BACKGROUND: Parents bereaved by suicide often say the death of their loved one happened "out of the blue". It is common for suicide in young people to be preceded by a number of indications of risk, including self-harm, the communication of suicidal ideas, and recent contact with services. We examined whether there is a group of young people who die by suicide without explicit warning signs, and if they indicate risk indirectly, through other suicide risk factors. METHODS: Using national mortality data, we identified a three-year UK national case series of deaths by suicide in people aged 10-19. We extracted information on the antecedents of suicide from coroner inquests and other official investigations into these deaths. RESULTS: There were 595 suicides by young people between 2014 and 2016. We obtained data for 544 (91%). Around a third (n = 161, 30%) had no known history of suicidal ideas or self-harm. This group also had low rates of other risk factors for suicide, including substance misuse, a mental health diagnosis, recent adverse life events, and of contact with services. LIMITATIONS: We relied on information provided to inquests and other investigations: under-reporting, especially on sensitive issues, is likely. Families and other witnesses may have under-reported warning signs that suggest they could have intervened. CONCLUSION: Suicide after minimal warning appears to be relatively common in young people. Suicidal ideas may develop rapidly in this age group and crisis services should therefore be widely available. Future prevention cannot rely on explicit expressions of risk.

Children and young people who die by suicide: childhood-related antecedents, gender differences and service contact.

BACKGROUND: Worldwide suicide is commonest in young people and in many countries, including the UK, suicide rates in young people are rising. AIMS: To investigate the stresses young people face before they take their lives, their contact with services that could be preventative and whether these differ in girls and boys. METHOD: We identified a 3-year UK national consecutive case series of deaths by suicide in people aged 10-19, based on national mortality data. We extracted information on the antecedents of suicide from official investigations, primarily inquests. RESULTS: Between 2014 and 2016, there were 595 suicides by young people, almost 200 per year; 71% were male (n = 425). Suicide rates increased from the mid-teens, most deaths occurred in those aged 17-19 (443, 74%). We obtained data about the antecedents of suicide for 544 (91%). A number of previous and recent stresses were reported including witnessing domestic violence, bullying, self-harm, bereavement (including by suicide) and academic pressures. These experiences were generally more common in girls than boys, whereas drug misuse (odds ratio (OR) = 0.54, 95% CI 0.35-0.83, P = 0.006) and workplace problems (OR 0.52, 95% CI 0.28-0.96, P = 0.04) were less common in girls. A total of 329 (60%) had been in contact with specialist children's services, and this was more common in girls (OR 1.86, 95% CI 1.19-2.94, P = 0.007). CONCLUSIONS: There are several antecedents to suicide in young people, particularly girls, which are important in a multiagency approach to prevention incorporating education, social care, health services and the third sector. Some of these may also have contributed to the recent rise.

Suicide in children and young people in England: a consecutive case series.

BACKGROUND: There is concern about the mental health of children and young people and a possible rise in suicidal behaviour in this group. We have done a comprehensive national multi-agency study of suicide in under 20s in England. We aimed to establish how frequently suicide is preceded by child-specific and young person-specific suicide risk factors, as well as all-age factors, and to identify contact with health-care and social-care services and justice agencies. METHODS: This study is a descriptive examination of suicide in a national consecutive sample of children and young people younger than 20 years who died by suicide in England between Jan 1, 2014, and April 30, 2015. We obtained general population mortality data from the Office for National Statistics (ONS). We collected information about antecedents considered to be relevant to suicide (eg, abuse, bullying, bereavement, academic pressures, self-harm, and physical health) from a range of investigations and inquiries, including coroner inquest hearings, child death investigations, criminal justice system reports, and the National Health Service, including data on people in contact with mental health services in the 12 months before their death. FINDINGS: 145 suicides in people younger than 20 years were notified to us during the study period, of which we were able to obtain report data about antecedents for 130 (90%). The number of suicides rose sharply during the late teens with 79 deaths by suicide in people aged 18-19 years compared with 66 in people younger than 18 years. 102 (70%) deaths were in males. 92 (63%) deaths were by hanging. Various antecedents were reported among the individuals for whom we had report data, including academic (especially exam) pressures (35 [27%] individuals), bullying (28 [22%]), bereavement (36 [28%]), suicide in family or friends (17 [13%]), physical health conditions (47 [36%]), family problems (44 [34%]), social isolation or withdrawal (33 [25%]), child abuse or neglect (20 [15%]), excessive drinking (34 [26%]), and illicit drug use (38 [29%]). Suicide-related internet use was recorded in 30 (23%) cases. In the week before death 13 (10%) individuals had self-harmed and 35 (27%) had expressed suicidal ideas. 56 (43%) individuals had no known contact with health-care and social-care services or justice agencies. INTERPRETATION: Improved services for self-harm and mental health are crucial to suicide prevention, but the wide range of antecedents emphasises the roles of schools, primary care, social services, and the youth justice system.

Mental health service changes, organisational factors, and patient suicide in England in 1997-2012: a before-and-after study.

BACKGROUND: Research into which aspects of service provision in mental health are most effective in preventing suicide is sparse. We examined the association between service changes, organisational factors, and suicide rates in a national sample. METHODS: We did a before-and-after analysis of service delivery data and an ecological analysis of organisational characteristics, in relation to suicide rates, in providers of mental health care in England. We also investigated whether the effect of service changes varied according to markers of organisational functioning. FINDINGS: Overall, 19 248 individuals who died by suicide within 12 months of contact with mental health services were included (1997-2012). Various service changes related to ward safety, improved community services, staff training, and implementation of policy and guidance were associated with a lower suicide rate after the introduction of these changes (incidence rate ratios ranged from 0·71 to 0·79, p<0·0001). Some wider organisational factors, such as non-medical staff turnover (Spearman's r=0·34, p=0·01) and incident reporting (0·46, 0·0004), were also related to suicide rates but others, such as staff sickness (-0·12, 0·37) and patient satisfaction (-0·06, 0·64), were not. Service changes had more effect in organisations that had low rates of staff turnover but high rates of overall event reporting. INTERPRETATION: Aspects of mental health service provision might have an effect on suicide rates in clinical populations but the wider organisational context in which service changes are made are likely to be important too. System-wide change implemented across the patient care pathway could be a key strategy for improving patient safety in mental health care. FUNDING: The Healthcare Quality Improvement Partnership commissions the Mental Health Clinical Outcome Review Programme, National Confidential Inquiry into Suicide and Homicide by People with Mental Illness, on behalf of NHS England, NHS Wales, the Scottish Government Health and Social Care Directorate, the Northern Ireland Department of Health, Social Services and Public Safety, and the States of Jersey and Guernsey.

Serious violence by people with mental illness: national clinical survey.

This study aimed to estimate the prevalence of mental disorder in offenders convicted of serious violence, examine their social and clinical characteristics, and compare them with patients convicted of homicide. We examined a national clinical survey of all people convicted of serious violence in England and Wales in 2004. Mental disorder was measured by contact with mental health services within 12 months of the offense. Of the 5,966 serious violent offenders, 293 (5%) had been in recent contact with mental health services. Personality disorder (63, 22%) and schizophrenia (55, 19%) were the most common diagnoses. Most had previous convictions for violence (168, 61%). Seventy-two (25%) patients were at high risk of violence and 34 (49%) were not subject to the Care Programme Approach. Compared with serious violence offenders, homicide offenders were more likely to have been patients (293, 5% vs. 65, 10%; p < .01). We conclude that patients were responsible for a small proportion of serious violent offenses; however, high-risk patients require closer supervision, and regular inquiry about changing delusional beliefs, thoughts of violence, and weapon carriage.

Patients with mental illness as victims of homicide: a national consecutive case series.

BACKGROUND: The media attention received by homicides committed by patients with mental illness is thought to increase stigma. However, people with mental illness can also be victims of violence. We aimed to assess how often victims of homicide are current mental health patients and their relationship to the perpetrators. METHODS: In a national consecutive case-series study, we obtained data for victims and perpetrators of all confirmed homicides between Jan 1, 2003, and Dec 31, 2005, in England and Wales. We requested information about contact with mental health services in the 12 months before the homicide for all victims and perpetrators. For victims and perpetrators who had contact with mental health services in the 12 months before homicide, we sent questionnaires to the clinician responsible for the patient's care. FINDINGS: 1496 victims of confirmed homicide died between Jan 1, 2003, and Dec 31, 2005, in England and Wales. Patients with mental illness were more likely to die by homicide than were people in the general population (incidence rate ratio 2·6, 95% CI 1·9-3·4). 90 homicide victims (6%) had contact with mental health services in the 12 months before their death. 213 patients with mental illness were convicted of homicide in the same 3 year period. 29 of 90 patient victims were killed by another patient with mental illness. In 23 of these 29 cases, the victim and perpetrator were known to each other, and in 21 of these cases, the victims and perpetrators were undergoing treatment at the same National Health Service Trust. In these 29 cases in which patient victims were killed by another patient with mental illness, alcohol and drug misuse (19 victims [66%], 27 perpetrators [93%]) and previous violence (7 victims [24%], 7 perpetrators [24%]) were common in both victims and, particularly, perpetrators. In seven of the 29 cases in which the victim was killed by another patient with mental illness, both victim and perpetrator were diagnosed with schizophrenia. INTERPRETATION: The high risk of patients with mental illness being victims of homicide is an important antistigma message, although this risk partly comes from other patients with mental illness; overall, the risk of patients committing homicide is greater than the risk of being a victim of homicide. Identification and safeguarding of patients at risk of violence should be prominent in clinical risk assessment. FUNDING: Healthcare Quality Improvement Partnership.

Homicide perpetrated by older people.

OBJECTIVE: This study aims to describe the circumstances in which older people commit homicide, the form of assessment they undergo and to examine the proportion of those who suffer from mental illness. METHODS: The study was carried out as part of the England and Wales National Confidential Inquiry into Suicide and Homicide by People with Mental Illness based on a five-year sample. The Inquiry was notified of the names of those over the age of 60 years convicted of homicide and also the details of the offence, sentencing and outcome in court by the Home Office. The Inquiry collected clinical data of those known to have had contact with mental health services from the responsible service and also retrieved psychiatric reports of those convicted. RESULTS: Homicide incidents perpetrated by older people typically involve a man killing his partner in an impulsive manner. The most common method was by using a sharp instrument (34%), followed by the use of a blunt instrument (26%). The use of firearms was rare (11%). Perpetrators aged 65 years and older were significantly more likely to kill a current or former spouse/partner and less likely to kill an acquaintance. Forty-four per cent of perpetrators over 65 years old suffered from depression at the time of the offence, whereas rates of schizophrenia and alcohol dependence were low. CONCLUSIONS: The information used in the study was extracted from a unique national database of homicide perpetrators. The characteristics and the circumstances of homicides perpetrated by older people are different to other age groups. An older-people homicide may be preventable if depression is identified early in older people.

Comparison of British national newspaper coverage of homicide committed by perpetrators with and without mental illness.

OBJECTIVE: Adverse newspaper reporting of mental illness and in particular, violence committed by a mentally ill person, is thought to contribute to stigma. However, violent events are also considered highly newsworthy by journalists. The aim of this study was to compare the likelihood of newspaper reporting for convicted perpetrators of homicide with and without a history of contact with mental health services. METHOD: A 12 month (April 2000-March 2001) cohort of 577 homicide perpetrators with and without a history of contact with mental health services in England and Wales was examined. These cases were identified by the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness. By examining 12 national newspapers, we compared the likelihood of reporting homicide perpetrators with and without mental illness. RESULTS: Under half (228 cases, 40%) of the homicide perpetrators were reported in at least one of the study newspapers. Under a fifth (94 cases, 16%) of perpetrators had a history of contact with mental health services and such previous contact did not increase the likelihood of newspaper reporting (odds ratio 1.0 (0.6-1.6)). CONCLUSIONS: Previous contact with mental health services did not influence the newsworthiness of a homicide perpetrator. The stigmatizing effect of reporting homicide by perpetrators with mental illness may relate more to the quality of reporting rather than selective over-reporting.

A population-based study of juvenile perpetrators of homicide in England and Wales.

This study aimed to describe the social, behavioural and offence characteristics of all convicted perpetrators of homicide aged 17 and under; to examine their previous contact with mental health services, and to discuss strategies for homicide prevention. An eight-year (1996-2004) sample of 363 juvenile homicide perpetrators in England and Wales was examined. The majority of perpetrators were male, used a sharp instrument, and most victims were acquaintances or strangers. Over half had previously offended. A history of alcohol and/or drug misuse was common, as was the prevalence of family dysfunction, abuse, educational difficulties or discipline problems. Previous contact with mental health services was rare. Earlier intervention targeting social and psychological adversity and substance misuse could help to reduce the level of risk for future violence, and may reduce homicide rates among juveniles. Strengthening engagement with young offenders and increasing resources to prevent recidivism may also be beneficial.

Suicide in dementia: 9-year national clinical survey in England and Wales.

BACKGROUND: Knowledge of suicide in people with dementia is limited to small case series. AIMS: To describe behavioural, clinical and care characteristics of people with dementia who died by suicide. METHOD: All dementia cases (n=118) from a 9-year national clinical survey of suicides in England and Wales (n=11 512) were compared with age- and gender-matched non-dementia cases (control group) (n=492) by conditional logistic regression. RESULTS: The most common method of suicide in patients with dementia was self-poisoning, followed by drowning and hanging, the latter being less frequent than in controls. In contrast to controls, significantly fewer suicides occurred within 1 year of diagnosis in patients with dementia. Patients with dementia were also less likely to have a history of self-harm, psychiatric symptoms and previous psychiatric admissions. CONCLUSIONS: Known indicators of suicide risk are found less frequently in dementia suicide cases than non-dementia suicide cases. Further research should clarify whether suicide in dementia is a response to worsening dementia or an underappreciation of psychiatric symptoms by clinicians.

The repetition of suicidal behavior: a multicenter cohort study.

OBJECTIVES: To determine the proportion of individuals who repeated nonfatal suicidal behavior within 12 months of an index episode, to investigate the timing of repetition, and to investigate risk factors associated with repetition and their population impact. METHOD: We carried out a prospective cohort study (1997-2002) in 4 large hospitals in North West England. We included subjects aged 15 years and over who attended with "self-harm" (an act of intentional self-poisoning or injury irrespective of the apparent purpose of the act). Following the episode, a standard assessment form, which included detailed demographic and clinical data, was completed by a clinician. RESULTS: 9213 individuals presented during the study period. The incidence of repetition within 12 months of the index episode was 13.6% (95% CI: 12.9% to 14.4%). The median time to first repetition was 73.5 days (interquartile range, 20 to 187 days). One in 10 subjects repeated within 5 days of the index episode. Independent risk factors for repetition included previous suicidal behavior, psychiatric treatment, being unemployed or registered sick, self-injury, alcohol misuse, and reporting suicidal plans or hallucinations at the time of the index episode. The combined population attributable fraction (an indicator of the potential population impact) for these variables was 65%. CONCLUSION: The repetition of suicidal behavior is common and occurs quickly. On a population level, our study suggests that the most important strategies to reduce repetition might include primary prevention of suicidal behavior, targeting psychiatric illness, and tackling social factors such as unemployment. Specific interventions may be required for individual subgroups.
