Current Issues within the Perinatal Mental Health Care System in Japan: A Cross-Sectional Questionnaire Survey
Abstract Background: Mental illness commonly occurs in reproductive age, and its adverse effects on mothers and children are a major public health concern. However, the extent to which the perinatal mental health care system in Japan is functioning adequately remains unexplored. This study aimed to identify the issues that exist within the perinatal mental health care system in Japan. Methods: A cross-sectional survey was conducted across medical facilities in Aichi prefecture in central Japan. Questionnaires were mailed to the head physicians of all 128 maternity care units, 21 neonatal intensive care units (NICUs), and 40 assisted reproductive technology (ART) units. The following data were collected: the number of admissions to mental health care units and admissions of neonates born to mothers with mental illness during the perinatal period between 2016 and 2018. Perspectives on psychotropic drug use during pregnancy were compared across different types of maternity care units, including maternal-fetal (MF) centers and private clinics by Fisher’s exact test. The multidisciplinary team system was also compared across different types of maternity care units by Fisher’s exact test. Results: The number of admissions to mental health care units was 82 (52.8 per 10 000 births), and 158 (1.0 per 1000 births) neonates born to mothers with mental illness were admitted to NICUs during the aforementioned period. With regard to the multidisciplinary team system, 84 (71.1 %) and 76 (64.4 %) maternity care units did not have any psychiatrists or social workers. Moreover, only 5 % of the head physicians in MF centers endorsed the discontinuation of psychotropic drug use during pregnancy. The corresponding figures were 20–35 % among those in general hospitals, private clinics, and ART units. Conclusions: Multidisciplinary system resources were perceived to be limited. Perspectives on psychotropic drug use during pregnancy differed significantly based on the type of units in which the doctors were working. There is a need for resources that will facilitate the admission of perinatal women with mental illnesses to mental health care units in Japan.
