Aim
• To continue the investigation of intentional injury among children and youth aged 5-19 years in BC, including: – suicide gestures– suicide attempts– self harm by ingestion, cutting, and burns &
hanging
Methods
• Using the BC CHIRPP database, cases coded as intentional self harm were selected and analyzed for the years 1997 to 2002, ages five years and over
• Descriptive analysis provided for the dataset as a whole, as well as subdivided into the following five categories: – Suicide gestures– Suicide attempts– Ingestion– Cutting– Burns & Hanging
Limitations • CHIRPP data is:
– self reported by the patient, or reported by proxy by a parent or guardian
– taken from the chart
• Older teens do not always present at paediatric hospitals– age group above 15 years is under represented
• Cases presenting to BC Children’s Hospital are not representative of a specific geographic area– no trends can be suggested

Burns & Hanging
• 6 hangings
• ≤ 5 burn cases
Visit Disposition
• Of all BC CHIRPP self-harm cases, patients were most likely to be admitted to hospital for:– Suicide attempts (60%)– Ingestions (50%)– Suicide gestures (31%)– Cutting (17%)
Discussion
• Deliberate self-harm is recognized as a distinct set of practices separate from suicide attempts or gestures
• Variously defined as the deliberate and voluntary infliction of physical harm to one’s own body that is not life threatening and is without any conscious suicidal intent

Self Destructive Behaviour
Discussion
• Deliberate self-harm behaviour typically originates in adolescence
• There are demonstrated differences in their distributions according to sex– Males at all ages are consistently more likely
than females to commit suicide – Deliberate self-harm is more common among
females than males
Discussion
• Success of male suicide can be accounted for by their tendency to use more lethal and irreversible methods such as hanging and firearms
• Females tend toward the use of poisons, gases, and drugs
Discussion
• This study determined that deliberate self-harm acts among adolescents presenting to the BC Children’s Hospital were predominately:– suicide attempts (36%)– ingestion (35%)
• Of all suicide attempts, 75% were by ingestion
Discussion
• Ingestion was predominately through the use of acetaminophen/ASA and psychoactive medication
• Most common place chosen for the attempt was the young person's home (41%)
Conclusions
• Hospital separation data indicate that self harm among males aged 15-24 years have declined over the past 12 years, from approximately 140 to 60 per 100,000
• The trend among females aged 15-19 years declined from approximately 350 to 175 per 100,000
Conclusions
• Further investigation is warranted to determine the full extent of the problem in BC, as well as to explore prevention and treatment options for youth and support for their families
