This paper discusses medical teams, projects and committees in which psychiatrists are involved, and describes activities of medical teams in general hospitals, such as non-psychiatric hospitals and university-based hospitals. Medical teams at general hospitals in which psychiatric staff take an initiative include psychiatric liaison teams, palliative care teams, and dementia care teams. Activities of these teams, when they meet the institutional standard, can be taken into consideration for calculation of medical fees, and the contents of their medical services are clearly described. Teams in which other departments or the hospital itself take an initiative and psychiatrists regularly join, on the other hand, include teams for organ transplantation, obstetrics and pediatrics, medical genetics, and HIV care. Psychiatrists may sometimes, if not regularly, take part in ethical consultation, committees for abuse prevention, and projects for on-the-premise suicide prevention. These activities are not directly associated with medical fees, but are critical in improving the quality of medical care, which is the very purpose of team medicine, and promoting medical safety. Evidence regarding the utility of team activities is currently insufficient, and evidence regarding team medicine needs to be accumulated.
