This article reviews recent trends in the provision of psychiatric services to the emergency departments of tertiary hospitals in Australia, involving the establishment of specialised in-reach or liaison services as well as various forms of short stay unit attached to emergency departments. The Emergency Psychiatry Service at Flinders Medical Centre, South Australia, is described as a case example. Its specialised models of assessment and clinical care are described, highlighting how these are differentiated from more traditional models in inpatient, community and general hospital consultation–liaison psychiatry.

Emergency psychiatry, and in particular the application of specialised psychiatric models of in-reach service and short stay units, is an increasingly important and growing field of psychiatry that warrants further exploration in research. The Emergency Psychiatry Service at Flinders Medical Centre has developed a distinct group of assessment and treatment approaches that exemplifies this growing field.
