Self-harm in Child and Adolescent Psychiatric Inpatients: A Retrospective Study.

OBJECTIVE This study presents a comprehensive report of children and adolescents who engaged in self-harm during their admission to a psychiatric inpatient unit. METHOD A chart review was conducted on all admissions to an acute care psychiatric inpatient unit in a Canadian children's hospital over a one-year period. Details on patients with self-harm behaviour during the admission were recorded, including: demographics, presentation to hospital, self-harm behaviour and outcome. Baseline variables for patients with and without self-harm behaviour during admission were compared. RESULTS Self-harm incidents were reported in 60 of 501 (12%) admissions during the one-year period of the study. Fourteen percent of patients (50 of 351) accounted for total number of 136 self-harm incidents. Half of these incidents (49%) occurred outside of the hospital setting, when patients were on passes. Using the Beck Lethality Scale (0-10), mean severity of the self-injury attempts was 0.33, and there were no serious negative outcomes. CONCLUSION Self-harm behaviour during inpatient psychiatric admission is a common issue among youth, despite safety strategies in place. While self-harm behaviour is one of the most common reasons for admission to psychiatric inpatient unit, our understanding of nature of these acts during the admission and contributing factors are limited. Further research is required to better understand these factors, and to develop strategies to better support these patients.
