Factors associated with suicide after parasuicide in young people.

OBJECTIVE--To determine factors associated with completed suicide in young parasuicide patients. DESIGN--Case-control study. SETTING--Regional poisoning treatment centre in a teaching general hospital. SUBJECTS--Patients who, between 1968 and 1985 when aged 15-24 years, were admitted to the regional poisoning treatment centre because of deliberate self poisoning or self injury. Cases (n = 62) consisted of those who by the end of 1985 had died locally from either suicide (n = 41) or possible suicide (n = 21). Controls (n = 124) were patients who were known not to have died locally during the study period. Two controls were selected for each case, matched by sex, age (within two years), and length of follow up. MAIN OUTCOME MEASURES--Possible predictors of completed suicide. RESULTS--Univariate analysis (conditional logistic regression) showed that risk of death due to suicide and possible suicide was associated with six factors: social class V (odds ratio 2.7, 95% confidence interval 1.1 to 6.7), unemployment (2.8, 1.4 to 5.8), previous inpatient psychiatric treatment (4.9, 2.2 to 10.9), substance misuse (3.3, 1.6 to 6.8), personality disorder (2.1, 1.03 to 4.4), and previous attempted suicide (2.3, 1.2 to 4.4). Multivariate analysis identified two factors as significantly contributing to the model that best discriminated between the cases and controls: substance misuse (alcohol or drugs, or both) (adjusted odds ratio 3.9) and previous inpatient psychiatric treatment (3.7). These factors seemed to be associated with suicide after attempted suicide in both the short term (less than 12 months) and the long term (one year or more) and were also identified when the analysis was restricted to subjects who definitely died by suicide and their controls. CONCLUSIONS--Suicide after parasuicide in young people is associated with substance misuse. This suggests that prevention of suicide in young people who attempt suicide might be improved by close liaison between general hospital services for patients who have attempted suicide and services for young substance misusers and by measures aimed at preventing substance misuse in young people.

Psychological treatment for atypical non-cardiac chest pain: a controlled evaluation

Thirty-one patients with atypical non-cardiac chest pain which had persisted despite negative medical investigation were treated in a controlled trial of cognitive-behavioural therapy. The average duration of pain was 4.7 years. Patients were randomized to either immediate treatment or as a control to assessment only. Treatment involved teaching patients how to anticipate and control symptoms, and modification of inappropriate health beliefs. The average number of sessions given was 7.2. There were significant reductions in chest pain. limitations and disruption of daily life, autonomic symptoms, distress and psychological morbidity in the treated group as compared with the control group who were unchanged. The assessment-only group were treated subsequently and showed comparable changes. Improvements were fully maintained by both treated groups at four- to six-months follow-up.

Deliberate self-harm patients who leave the accident and emergency department without a psychiatric assessment: a neglected population at risk of suicide

OBJECTIVES Deliberate self-harm (DSH) patients, despite their risk of suicide, are often discharged directly from accident and emergency (A&E) departments without undergoing a psychiatric assessment. The aims of this study were to determine the characteristics and outcome of these patients. METHODS The characteristics of DSH patients who were discharged directly from an A&E department over a 2-year period were investigated, comparing those who had a psychiatric assessment with those who did not. In a matched control design, the outcome of a group of patients who did not receive a psychiatric assessment was compared with that of a group of patients who were assessed. RESULTS Of DSH patients who were discharged directly from the A&E department 58.9% (145/246) did not have a psychiatric assessment. Nonassessed patients were more likely to have a past history of DSH, to be in the 20-34 year age group, and to have exhibited difficult behaviour in the A&E department. Patients presenting between 5 p.m. and 9 a.m. were less likely to be assessed than those attending between 9 a.m. and 5 p.m. Further DSH during the subsequent year occurred in 37.5% of the nonassessed patients compared with 18.2% of matched assessed patients. They were also more likely to have psychiatric treatment. CONCLUSION A substantial proportion of DSH patients discharged directly from A&E departments do not receive a psychiatric assessment. Nonassessed patients may be at greater risk of further DSH and completed suicide than those who are assessed. Hospital services need to be organised such that DSH patients managed in A&E departments can receive an assessment of psychosocial problems and risk.

Use of paracetamol for suicide and non-fatal poisoning in the UK and France: are restrictions on availability justified?

OBJECTIVE: To investigate the relationship between the availability of paracetamol and its use for overdose and suicide. DESIGN: Analysis of routinely collected information on time trends for paracetamol suicides, non-fatal overdoses, and sales. SETTING: England and Wales and France. RESULTS: There were strong correlations between trends in paracetamol sales in the UK and trends in non-fatal paracetamol overdose in Oxford between 1976 and 1993 (Spearmans r = 0.86; 95% confidence interval (CI) 0.54, 0.96) and between paracetamol sales and non-fatal overdoses in France between 1974 and 1990 (r = 0.99; 95% CI 0.97, 1.00). Sales figures were also correlated with paracetamol related suicides in both England and Wales, 1983-91 (r = 0.72; 95% CI 0.11, 0.94) and France, 1974-90 (r = 0.79; 95% CI 0.50, 0.92). Similarly strong relationships were observed between trends in non-fatal overdoses and suicide by paracetamol poisoning in England and Wales (r = 0.85; 95% CI 0.61, 0.95) and France (r = 0.79; 95% CI 0.50, 0.92). It is estimated that approximately 32,000 overdoses involving paracetamol occur annually in England and Wales. Fatality rates from paracetamol overdose were four times as high in England and Wales (0.4%, 95% CI 0.38, 0.46) as in France (0.1%, 95% CI 0.06, 0.17). CONCLUSION: Trends towards greater availability of paracetamol are paralleled by increases in its use for both non-fatal overdose and suicide. Paracetamol related morbidity and mortality seem to be less frequent in France where the quantity of paracetamol in a single purchase is limited. Although not conclusive, these data add to a body of evidence which suggests that restrictions in the quantity of paracetamol available as a single purchase in the UK may reduce suicide and liver failure related to paracetamol.

Recent clinical and epidemiological trends in parasuicide in Edinburgh and Oxford: a tale of two cities

This is a report of clinical and epidemiological trends in parasuicide in Edinburgh and Oxford over the period of 1976 to 1984. Rates of parasuicide declined in both cities, but more markedly among women than men. Male rates tended to be higher in Edinburgh and female rates higher in Oxford. Age-specific rates were similar for the two cities in 1983-84, with peak rates for females among 15-19 year olds and those for males among 20-24 year olds in Edinburgh and 25-34 year olds in Oxford. Parasuicide incidence was higher in lower social class groups and among the unemployed in both cities. During the study period there was a massive decline in barbiturate overdoses, a more modest decline in minor tranquillizer overdoses but, in Oxford, a marked increase in self-poisoning with paracetamol. By the end of the study period the proportion of patients receiving a diagnosis of drug addiction had doubled in Edinburgh, although it had remained fairly constant in Oxford. There were differences in patterns of aftercare offered to patients in the two cities; these almost certainly reflect differing clinical policies.

Association between epilepsy and attempted suicide

In a two-year study of patients admitted to hospital after deliberate self-poisoning or self-injury, a fivefold excess of patients with epilepsy was found compared with general population prevalence rates. Males with epilepsy were particularly over-represented. Patients with epilepsy were prone to make repeat attempts. Anticonvulsants, particularly barbiturates, were used in most cases of self poisoning.

The geographical distribution of suicides in farmers in England and Wales

Abstract Farmers in England and Wales have an elevated risk of suicide. The aim of this study was to investigate the geographical distribution of suicides in farmers. Rates of suicide (including suicide and open verdicts) of farmers in England and Wales between 1981 and 1993 were calculated on a county basis. Trends in rates and differences in rates between counties, regions and England and Wales were then analysed. There were 719 suicides (634 suicide verdicts and 85 open verdicts). There was evidence of a decline in annual rates of suicide in farmers during the study period in England but not Wales. There was no evidence of geographical heterogeneity of farming suicides according to counties, but a relatively high rate for Devon (N = 62 suicides). County farming suicide rates did not appear to be related to local general population suicide rates, density of farmers or type of farm holding. While identification of counties with relatively large numbers of farming suicides should assist targeting of local preventive programmes, it is clear that any significant prevention strategies should be implemented on a national basis.

Attempted suicide in Oxford University students, 1976-1990.

During the 14 years between the beginning of academic year 1976-7 and the end of academic year 1989-90, 216 Oxford University students (119 females and 97 males) were referred to the general hospital in Oxford because of suicide attempts (254 in all). The rate of attempted suicide during university term-time (106/100,000) was lower than in other young people of similar age in Oxford City (164/100,000). The difference was particularly marked in females (178/100,000 v. 269/100,000). The lower rate in the students may in part reflect their generally higher socio-economic status. Very few of the attempts by the students appeared to be failed suicides. The most frequent problems faced by the students at the time of their attempts were interpersonal, especially difficulties regarding partners, followed by academic problems. The latter were usually problems with ongoing course work rather than with the Finals examinations. Approximately a quarter of the students had psychiatric problems, with personality disorders and depression being most common. At least 30% had a history of previous attempts. Suggestions are made concerning measures for improving the management and prevention of attempted suicide by students.

Repetition of attempted suicide: The performance of the Edinburgh predictive scales in patients in Oxford

Abstract Non-fatal suicidal behaviour is often repeated especially in the first few months after an attempt. Repetition increases the risk of eventual completed suicide. Scales have been developed to predict the risk of repetition, particularly in the short-term. We have tested a recently developed scale from Edinburgh in two one-year cohorts of patients assessed in routine clinical practice following attempts that resulted in referral to the general hospital in Oxford. The scale was tested in both its clinical and research (weighted item) versions, first, as originally evaluated by its originators and, second, using only first attempts by individual persons rather than any episode (i.e., including repeat episodes) during the study periods as the index events and a standard one year follow-up period, rather than within a calendar year period. We also compared the performance of the scale with a short scale, again from Edinburgh, which was developed in the 1970s. The new Edinburgh Risk of Repetition Scale ...

Deliberate self-poisoning and self-injury in the Oxford area: 1972–1980

SummaryTrends in deliberate self-poisoning and self-injury in the Oxford area have been monitored between 1972 and 1980 by examination of data on all referrals to the general hospital in Oxford. The incidence of self-poisoning and self-injury in Oxford City increased between 1972 and 1978, although far more slowly than in previous years, and then flattened out in the late 1970s. The highest incidence for females during the period under review was found in age group 15–24 years and for males in age group 25–34 years. The numbers of young adolescents being referred have increased recently. Overall annual rates of repetition remained very stable until 1978 but showed a decline in 1979. Self-poisoning with non-opiate analgesics became more common during the study period; this was entirely due to the increased use of paracetamol. There was a small decline in the use of minor tranquillisers and sedatives in self-poisoning during the last 2 years of the study. The use of alcohol in association with attempts was more common among males than females. Similarly, higher rates of alcoholism, drug addiction and epilepsy were found in male subjects.
