Effect of death of Diana, princess of Wales on suicide and deliberate self-harm.

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.

Suicide within 12 months of contact with mental health services: national clinical survey.

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.

Mental disorder and clinical care in people convicted of homicide: national clinical survey.

OBJECTIVES: To estimate the rate of mental disorder in those convicted of homicide and to examine the social and clinical characteristics of those with a history of contact with psychiatric services. DESIGN: National clinical survey. SETTING: England and Wales. SUBJECTS: Eighteen month sample of people convicted of homicide. MAIN OUTCOME MEASURES: Offence related and clinical information collected from psychiatric court reports on people convicted of homicide. Detailed clinical data collected on those with a history of contact with psychiatric services. RESULTS: 718 homicides were reported to the inquiry between April 1996 and November 1997. Of the 500 cases for whom psychiatric reports were retrieved, 220 (44%; 95% confidence interval 40% to 48%) had a lifetime history of mental disorder, while 71 (14%; 11% to 17%) had symptoms of mental illness at the time of the homicide. Of the total sample, 102 (14%; 12% to 17%) were confirmed to have been in contact with mental health services at some time, 58 (8%; 6% to 10%) in the year before the homicide. The commonest diagnosis was personality disorder (20 cases, 22%; 13% to 30%). Alcohol and drug misuse were also common. Only 15 subjects (18%; 10% to 26%) were receiving intensive community care, and 60 (63%; 53% to 73%) were out of contact at the time of the homicide. CONCLUSIONS: There are substantial rates of mental disorder in people convicted of homicide. Most do not have severe mental illness or a history of contact with mental health services. Inquiry findings suggest that preventing loss of contact with services and improving the clinical management of patients with both mental illness and substance misuse may reduce risk, but clinical trials are needed to examine the effectiveness of such interventions.

Determinants of folic acid knowledge and use among antenatal women.

BACKGROUND: Although recommendations on folic acid use were issued by health authorities in a number of countries in the early 1990s, uptake of peri-conceptional folic acid is still disappointingly low. Regardless of food fortification policies, folic acid promotion will probably be required in most countries to optimize folate levels among women of child-bearing age. The aim of this study was to examine folic acid knowledge and use, and their determinants among antenatal women in the east of Ireland in 1997. METHODS: Three hundred antenatal women attending their initial booking appointment in three Dublin maternity hospitals were surveyed. An interviewer-administered questionnaire was used with questions on folic acid knowledge and use, and demographic and obstetric questions. A univariate analysis of data was undertaken followed by a multivariate analysis using logistic regression to determine factors predicting knowledge and use of folic acid. RESULTS: Seventy-six per cent of respondents had heard of folic acid, 16 per cent had taken it before pregnancy and 51 per cent during pregnancy. Women who had planned their pregnancy, were married and were relatively affluent were significantly more likely to have heard of folic acid, to know that it could prevent neural tube defects and to have taken it peri-conceptionally. Less affluent women tended to use their general practitioner (GP) more as a source of information and advice than those who were better off. In multivariate analysis, marriage and planned pregnancy were important predictors of folic acid knowledge whereas planned pregnancy advice given before pregnancy and relative affluence were predictive of peri-conceptional use. CONCLUSIONS: Many women know of folic acid but do not take it peri-conceptionally. Women may associate folic acid with pregnancy and less with pre-pregnancy. Greater emphasis on peri-conceptional use should improve folic acid uptake. Focusing on less affluent women for folic acid promotion by GPs and other primary care professionals is also important.

Folic acid knowledge and use among expectant mothers in 1997: a comparison with 1996.

This study examined changes in folic acid knowledge and use among antenatal women in Dublin maternity hospitals between 1996 and 1997, following a campaign to improve the very low uptake of peri-conceptional folic acid. The results showed significant improvements between the two years. Almost 76% of respondents had heard of folic acid in 1997 compared with 54% in 1996 (p < 0.01), with a shift in the proportion of people hearing of folic acid from hospital doctors to general practitioners (GP). Almost 43% of respondents in 1997 knew that folic acid can prevent spina bifida compared with 21% in 1996 (p < 0.01). A higher proportion was taking folic acid prior to conception in 1997 (16% vs 6%, p < 0.01). We conclude that the improvements may have been in part due to the promotional campaign among health professionals, women's groups and the media. However, less than a fifth of women were taking folic acid peri-conceptionally in 1997 and there is still scope for much improvement.

Knowledge and use of peri-conceptional folic acid among antenatal patients.

Peri-conceptional folic acid can prevent more than half of all neural tube defects (NTDs). A cross-sectional interviewer administered study was undertaken among 300 women attending their first antenatal appointment in the three major Dublin maternity hospitals. The aim of the study was to monitor knowledge and behaviour with respect to peri-conceptional folic acid among antenatal patients. There was a 98% (295/300) response rate. 53.6% (158/295) had heard of folic acid. Such knowledge was significantly associated with age over 30 years (p < 0.001), a planned pregnancy (p < 0.001) and being married (p < 0.001). The majority (58.2%) found out about folic acid from lay sources such as friends or the media. One eighth (12.9%, 38/295) had been advised to take folic acid before pregnancy, the majority (58.3%, 21/38) having been advised by doctors. 21% (62/295) knew that it prevented spina bifida. 5.8% (17/295) had taken it before becoming pregnant. Taking folic acid before pregnancy was significantly associated with having a planned pregnancy (p < 0.005) and being married (p < 0.005). This study highlights the poor impact of health promotion campaigns to date and provides a challenge to health professionals.

Using research to implement change: the introduction of group activities on a psychiatric unit.

Staff in a psychiatric unit of a general hospital proposed the introduction of a programme of structured group activities, based on their casual observation that patients were sometimes unoccupied and bored. It was decided to collect data systematically in order to inform the implementation of activities. An activities record sheet was developed to list all activities taking place over a 1-week period. Questionnaires were administered to patients (n = 23) and staff (n = 20) on the unit to seek their views on the value, type, timing, frequency and location of activities as well as on other related aspects. Overall, staff made practical and realistic suggestions regarding the implementation of structured group activities. The data collected, although useful in planning change, raised questions about the poor quality of patients' responses and the low response rate (50%) from staff. Implications of these and other issues are discussed.
