Supporting the state of mind of child-rearing mothers is important for preventing child abuse. In our hospital, which is a general hospital for children, there are many medical departments, such as the perinatal and pediatric medical departments, and many occupations support medical treatment, but it is necessary to respond cooperatively. In obstetrics in the perinatal department, awareness of the prevention of child abuse from the pregnancy phase is increasing, and DV screening and surveys of social high-risk pregnant women (young, mental, and social) are being conducted. In the 2012-2016 survey of socially high-risk pregnant women, between 11% and 15% pregnant women of the 1,600 births per year were at social high-risk, and 4% had mental problems. At the time of visiting the obstetrics department, there are patients who continue to visit the psychiatry department, but there are many whose visits are interrupted or who do not visit. Patients who consent to visiting the psychiatry department in order to continue their pregnancy and prepare for childbirth are allowed visits, and after childbirth, we introduce them to a local psychiatry clinic and strive to provide information through public health nurses and other organizations. If the child needs to visit the hospital after childbirth, information is shared with the neonatal and pediatric medical departments. In the pediatric medical department, there are many mothers who are mentally unstable or are mentally ill. In such cases, psychologists and public health nurses are also involved, and it is important to discuss the burden of child care considering the mental state of the caregiver and to establish a cooperative system with related organizations. When inappropriate child care affects the child's development, we cooperate with the child psychiatry department to support child care. In cases with a high risk of abuse, the Child Abuse Prevention Committee shares information throughout the hospital and cooperates with multiple departments, including the perinatal department, pediatric medicine department, social workers, public health nurses, and psychologists, in order to continuously respond. We report on the collaboration in and outside of our hospital.
