Suicide-related internet use (SRIU), defined as internet use related to one's own feelings of suicide, can be both a risk and protective factor, especially for isolated individuals. Despite its influence on suicidality, clinicians face challenges in assessing SRIU because of the private nature of internet usage. Current recommendations on enquiring about SRIU in a clinical setting concern mostly young people.

To address the gap in understanding SRIU among patients of all ages, this study aims to explore mental health clinicians’ experiences, attitudes and beliefs regarding enquiring about SRIU, as well as the risks and benefits it presents in the assessment and management of patients. Finally, the study aims to establish the role SRIU potentially plays in the assessment and management of patients.

Twelve clinicians practising at secondary mental health services in England participated in interviews. Thematic analyses were used for data interpretation.

Clinicians who participated in interviews rarely initiate discussions on SRIU with their patients despite considering this an important factor in suicidality. Age of both patients and clinicians has the potential to influence enquiry into SRIU. Clinicians recognise the potential benefits of patients finding supportive online communities but also express concerns about harmful and low-quality online content related to suicide.

Integrating SRIU enquiry into standard clinical practice, regardless of the patient's age, is an important step towards comprehensive patient care. Broader training for clinicians on enquiring about online behaviours is essential to mitigate potential risks and harness the benefits of SRIU in mental health patients.

Homicide rates have fallen markedly in the UK over the past decade. There has been little research on whether homicides by people with mental disorder have contributed to this downward trend. Furthermore, there is limited information on trends in court outcomes for people with mental disorder who commit homicide.

To examine trends in general population homicide and homicide by people with mental disorder, and to explore court outcome.

We conducted a national, consecutive case series of homicide in England and Wales (1997–2015). Data were received from the Home Office Statistics Unit of Home Office Science. Clinical information was obtained from psychiatric reports and mental health services.

There has been a fall in the homicide rate in England and Wales since 2008. Despite this, the relative contribution of mental disorder as a proportion of all homicide has increased. Our findings also showed the inappropriate management of people with serious mental illness convicted of homicide. Of those who committed homicide and were diagnosed with schizophrenia, a third were imprisoned, and there was a marked fall in hospital order referrals. We found this to be linked to substance misuse comorbidity.

The proportional increase in homicide by people with schizophrenia suggests more complex factors may be driving rates, such as substance misuse. Addressing substance misuse comorbidity and maintaining engagement with services may help prevent patient homicide. Despite their complex needs, people with serious mental illness continue to be imprisoned. Improvements in assessment and the timely transfer of prisoners to health services are required.

It is estimated that 1 in 10 people have a personality disorder. People with emotionally unstable personality disorder are at high risk of suicide. Despite being frequent users of mental health services, there is often no clear pathway for patients to access effective treatments.

To describe the characteristics of patients with personality disorder who died by suicide, examine clinical care pathways and explore whether the care adhered to National Institute for Health and Care Excellence guidance.

National consecutive case series (1 January 2013 to 31 December 2013). The study examined the health records and serious incident reports of patients with personality disorder who died by suicide in the UK.

The majority had a diagnosis of borderline/emotionally unstable or antisocial personality disorder. A high proportion of patients had a history of self-harm (n = 146, 95%) and alcohol (n = 101, 66%) or drug misuse (n = 79, 52%). We found an extensive pattern of service contact in the year before death, with no clear pathway for patients. Care was inconsistent and there were gaps in service provision. In 99 (70%) of the 141 patients with data, the last episode of care followed a crisis. Access to specialised psychological therapies was limited; short-term in-patient admissions was adhered to; however, guidance on short-term prescribing for comorbid conditions was not followed for two-thirds of patients.

Continuity and stability of care is required to prevent, rather than respond to individuals in crisis. A comprehensive audit of services for people with personality disorder across the UK is recommended to assess the quality of care provided.

To explore the portrayal of homicide-suicide in newspaper articles, particularly how mental illness was reported. We carried out a qualitative study in England and Wales (2006–2008). Data from newspaper articles obtained via the LexisNexis database were used to examine a consecutive series of 60 cases.

A fascination with extreme violence, vulnerable victims and having someone to blame made homicide-suicides newsworthy. Some offenders were portrayed in a stereotypical manner and pejorative language was used to describe mental illness. The findings showed evidence of inaccurate and speculative reference to mental disorder in newspaper reports.

The media should avoid speculation on people's mental state. Accurate reporting is essential to reduce stigma of mental illness, which may in turn encourage people to seek help if they experience similar emotional distress.

The rise in homicides by those with serious mental illness is of concern, although this increase may not be continuing.

To examine rates of mental illness among homicide perpetrators.

A national consecutive case series of homicide perpetrators in England and Wales from 1997 to 2006. Rates of mental disorder were based on data from psychiatric reports, contact with psychiatric services, diminished responsibility verdict and hospital disposal.

Of the 5884 homicides notified to the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness between 1997 and 2006, the number of homicide perpetrators with schizophrenia increased at a rate of 4% per year, those with psychotic symptoms at the time of the offence increased by 6% per year. The number of verdicts of diminished responsibility decreased but no change was found in the number of perpetrators receiving a hospital order disposal. The likeliest explanation for the rise in homicide by people with psychosis is the misuse of drugs and/or alcohol, which our data show increased at a similar magnitude to homicides by those with psychotic symptoms. However, we are unable to demonstrate a causal association. Although the Poisson regression provides evidence of an upward trend in homicide by people with serious mental illness between 1997 and 2006, the number of homicides fell in the final 2 years of data collection, so these findings should be treated with caution.

There appears to be a concomitant increase in drug misuse over the period, which may account for this rise in homicide. However, an increase in the number of people in contact with mental health services may suggest that access to mental health services is improving. Previous studies have used court verdicts such as diminished responsibility as a proxy measure of mental disorder. Our data indicate that this does not reflect accurately the prevalence of mental disorder in this population.

Suicide prevention is a health service priority. Suicide risk may be greatest during psychiatric in-patient admission and following discharge.

To describe the social and clinical characteristics of a comprehensive sample of in-patient and post-discharge cases of suicide.

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).

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.

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.

Suicide prevention is a health service priority but the most effective approaches to prevention may differ between different patient groups.

To describe social and clinical characteristics in cases of suicide from different age and diagnostic groups.

A national clinical survey of a 4-year (1996–2000) sample of cases of suicide in England and Wales where there had been recent (< 1 year) contact with mental health services (n=4859).

Deaths of young patients were characterised by jumping from a height or in front of a vehicle, schizophrenia, personality disorder, unemployment and substance misuse. In older patients, drowning, depression, living alone, physical illness, recent bereavement and suicide pacts were more common. People with schizophrenia were often in-patients and died by violent means. About athird of people with depressive disorder died within a year of illness onset. Those with substance dependence or personality disorder had high rates of disengagement from services.

Prevention measures likely to benefit young people include targeting schizophrenia, dual diagnosis and loss of service contact; those aimed at depression, isolation and physical ill-health should have more effect on elderly people.

Previous studies of people convicted of homicide have used different definitions of mental disorder.

To estimate the rate of mental disorder in people convicted of homicide; to examine the relationship between definitions, verdict and outcome in court.

A national clinical survey of people convicted of homicide(n=1594) in England and Wales (1996–1999). Rates of mental disorder were estimated based on: lifetime diagnosis, mental illness at the time of the offence, contact with psychiatric services, diminished responsibility verdict and hospital disposal.

Of the 1594, 545 (34%) had a mental disorder: most had not attended psychiatric services; 85 (5%) had schizophrenia (lifetime); 164 (10%) had symptoms of mental illness at the time of the offence; 149 (9%) received a diminished responsibility verdict and 111 (7%) a hospital disposal – both were associated with severe mental illness and symptoms of psychosis.

The findings suggest an association between schizophrenia and conviction for homicide. Most perpetrators with a history of mental disorder were not acutely ill or under mental healthcare at the time of the offence. Some perpetrators receive prison sentences despite having severe mental illness.

Information on suicide by psychiatric patients from ethnic minority groups is scarce.

To establish the number of patients from ethnic minorities who kill themselves; to describe their suicide methods, and their social and clinical characteristics.

A national clinical survey was based on a 4-year sample of suicides in England and Wales. Detailed data were collected on those who had been in contact with mental health services in the year before death.

In total 282 patients from ethnic minorities died by suicide – 6% of all patient suicides. The most common method of suicide was hanging; violent methods were more common than in White patient suicides. Schizophrenia was the most common diagnosis. Ethnic minority patients were more likely to have been unemployed than White patients and to have had a history of violence and recent non-compliance. In around half, this was the first episode of self-harm. Black Caribbean patients had the highest rates of schizophrenia (74%), unemployment, living alone, previous violence and drug misuse.

In order to reduce the number of suicides byethnicminority patients, services should address the complex health and social needs of people with severe mental illness.
