Abuse and deliberate self-poisoning in women: a matched case-control study

OBJECTIVE

Controlled studies have shown deliberate self-harm to be more common in abused populations, but no controlled studies have shown abuse to be more common in self-harming populations. This is the first controlled study to determine whether abuse experiences (sexual, physical, and psychological) occurred more commonly in women who take overdoses than in controls.

METHOD

The design was a matched (1:1) case-control study set in a district general hospital in England. The subjects were 36 women admitted following deliberate self-poisoning. They were matched with the next non-overdose admission to the same hospital on six variables (sex, age, ethnicity, social class, marital status, and geographical locality). The main outcome measures used were modified versions of standardized self-report questionnaires of sexual, physical, and psychological abuse, together with measures of parenting style and general psychopathology.

RESULTS

Women who had taken an overdose were more likely (odds ratio 15.0, 95% confidence interval 2.0 to 113.6) to have been sexually abused, and somewhat more likely to have been psychologically (1.02, 1.00 to 1.05) but not physically abused. They also had higher measures of psychopathology (GHQ-30: 1.19, 1.07 to 1.31), were more likely to have been abused at a younger age, exposed to the "affectionless control" style of parenting by their mothers, and to have harmed themselves in other ways.

CONCLUSIONS

The management of women presenting to hospital after self-poisoning should include assessment of abuse experiences, and instigation of appropriate treatment in those with significant sequelae of abuse.

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.
