Children and adolescents with suicidal ideation or after suicide attempts are sometimes brought to pediatric emergency rooms, but no system has been established to deal with them.
 In this study, we examined 14 patients who presented to the emergency department of a children's hospital in Tokyo because of suicidal ideation or previous suicide attempt. Continuous support was provided except in cases where the patients were receiving treatment at other hospitals, but there were no visits to the hospital because of attempted suicide within 6 months after the initial visit. In the field of child psychiatry, continuous support through case management intervention may be effective in preventing suicide.
 Next, we reviewed and discussed randomized controlled trials of case management interventions for suicide attempters in Japan and abroad. The effectiveness of case management interventions in reducing the rate of suicide reattempts is inconsistent, with different studies reporting different degrees of effectiveness. On the other hand, it was demonstrated to be effective in improving follow-up rates and psychiatric symptoms, and it is recommended that these outcomes be considered when considering interventions for child and adolescent suicidal ideation and suicide attempts.
 In case management interventions to prevent child and adolescent suicide, it is important for medical care, health care, welfare, and education fields to work together to support children and their families.
