Deliberate self-harm in children and adolescents: an 11-year case note study.

OBJECTIVE

To retrospectively examine the case-notes of all children and adolescents admitted with deliberate self-harm (DSH) or suicidal ideation during the study period 1993-2003. The study aimed to identify underlying reasons why children and adolescents engage in DSH, and to identify common psychiatric, psychosocial and familial factors which may predispose or contribute to an individual's engagement in such behaviour.

METHOD

All children presenting to the hospital with DSH or suicidal ideation were identified and data collected from their case notes. A study specific questionnaire was designed to collect demographic details, details on clinical presentation, past attempts, comorbid psychiatry disorders, family history and family circumstances. Information was also recorded on hospital stay and discharge planning.

RESULTS

During the 11-year period, 231 children presented with suicidal ideation or behaviour. The mean age was 12.85 with an age range from 6-17 years, with a female:male ratio of 2.5:1. Overdose was the most common method (81.2%) and paracetamol most commonly the drug of choice. More than half of the group (55.7%) expressed a wish to die. More than half (51.8%) had expressed suicidal ideation in the past, 31% had made a previous attempt, and 11.7% had been previously admitted. Of the children 8% presented with suicidal behaviour more than once over the study period. There was a family history of completed suicide in 6.6%.

CONCLUSION

Deliberate self-harm in young people is a significant public health problem in Ireland. During the period of this study, rates have continued to increase. There is an urgent need for national bodies such as the National Suicide Review Group to extend their focus to include those under age 18 and for services to be developed that might reduce DSH behaviours. More research is needed in the area of childhood suicidal behaviour.
