Summary:Since November of 2022 year, we started the project of [Area 1] Suicide measures against children and young
people (topic number 1-5) " Social Implementation of Tele-mental Health Care for Depression in Children andDevelopment of Early Treatment System -Collaboration with KOKOROBO and Children's Registry of Mental Disorders.
" We also participated as program director and conducted monthly [Area1] meetings.
We collaborated with the project "Identification and Stratification of Homogeneous Populations Based on1【Topic number：R4-1-5】
Treatment Effectiveness, Relapse Risk, and Prognosis of Mental Disorders by Utilizing Longitudinal Data in Registries
and Cohorts" Research on treatment effectiveness, outcome prediction, and new stratification by utilizing mental disease
registries (Principal Investigator: Kazuyuki Nakagome). Related to this project, the ethical review of our study"Stratification of Treatment Effectiveness and Prognosis of Developmental Disorders and Mood Disorders in Children
Based on Analysis of Blood Samples and Longitudinal Data" was approved in 2022 year. (Data acquisition underway.)
The Mental Illness Registry is intended to be an objective, multifaceted assessment by collecting data on a large scale.
Accurate identification of the status of child and adolescent psychiatric disorders is thought to have a significant impact on
the success or failure of subsequent treatment, including suicide prevention, as well as on patient prognosis and quality oflife.
We collaborated with the project ‘KOKOROBO’ (An online mental health care system that prevents mentalillness, provides early treatment for those with mental illness, and bridges to medical care for those who need it; Principal
Investigator: Kazuyuki Nakagome.) In 2022, in addition to the promotion of social implementation and collaboration in
Chiba City, we conducted a survey of psychiatrists and pediatricians at our university to examine methods that would make
KOKOROBO easier for children to use in suicide prevention. At Chiba University Hospital, the Department of Child
Psychiatry and the Department of Psychiatry organically collaborated to create a system in which any physician can provide
child and adolescent psychiatric care. In addition, early psychiatric liaison intervention for urgent requests from pediatrics
and the development of an outpatient system for early consultation support are being promoted. The CHIBA TAIYO
Project: Treatment Access Intervention for the Young is a plan to promote regional medical collaboration among pediatrics,psychiatry, and child psychiatry in Chiba Prefecture, and promotes clinical research as well as organic collaboration among
pediatrics, psychiatry, and child psychiatry.
