RESUMO

BACKGROUND: The annual number of homicide convictions in England and Wales is increasing. Previous studies have highlighted the aetiological role of alcohol and drugs in homicide. AIMS: To examine rates of alcohol and drug misuse and dependence in people convicted of homicide; the role of alcohol and drugs in the offence; the social and clinical characteristics of alcohol- and drug-related homicides; and the social and clinical characteristics of patients with dual diagnosis who commit homicide. METHODS: A national clinical survey based on a 3-year (1996-9) consecutive sample of people convicted of homicide in England and Wales. Information on rates of alcohol and drug misuse/dependence, the role of alcohol and drugs in the offence and social and clinical characteristics of perpetrators were collected from psychiatric reports prepared for the court in homicide convictions. Detailed clinical information was gathered from questionnaires completed by mental health teams for those in contact with mental health services. RESULTS: Of the 1594 homicide perpetrators, more than one-third (42%) occurred in people with a history of alcohol misuse or dependence and 40% in people with a history of drug misuse or dependence. Alcohol or drug misuse played a contributory role in two-fifths of homicides. Alcohol played a major role in 52 (6%) and a minor role in 364 (39%) homicides. Drugs played a major role in six (1%) and a minor role in 138 (14%) homicides. Forty-two homicides (17%) were committed by patients with severe mental illness and substance misuse. Alcohol- and drug-related homicides were generally associated with male perpetrators who had a history of violence, personality disorders, mental health service contact and with stranger victims. CONCLUSIONS: Substance misuse contributes to the majority of homicides in England and Wales. A public health approach to homicide would highlight alcohol and drugs before severe mental illness.

RESUMO

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.

RESUMO

BACKGROUND: Previous studies of people convicted of homicide have used different definitions of mental disorder. AIMS: To estimate the rate of mental disorder in people convicted of homicide; to examine the relationship between definitions, verdict and outcome in court. METHOD: 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. RESULTS: 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. CONCLUSIONS: 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.

RESUMO

BACKGROUND: Information on suicide by psychiatric patients from ethnic minority groups is scarce. AIMS: To establish the number of patients from ethnic minorities who kill themselves; to describe their suicide methods, and their social and clinical characteristics. METHOD: 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. RESULTS: 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. CONCLUSIONS: In order to reduce the number of suicides by ethnic minority patients, services should address the complex health and social needs of people with severe mental illness.
