Involuntary admission and treatment of patients with mental disorder.

Despite the efforts of the World Health Organization to internationally standardize strategies for mental-health care delivery, the rules and regulations for involuntary admission and treatment of patients with mental disorder still differ markedly across countries. This review was undertaken to describe the regulations and mental-health laws from diverse countries and districts of Europe (UK, Austria, Denmark, France, Germany, Italy, Ireland, and Norway), the Americas (Canada, USA, and Brazil), Australasia (Australia and New Zealand), and Asia (Japan and China). We outline the criteria and procedures for involuntary admission to psychiatric hospitals and to community services, illustrate the key features of laws related to these issues, and discuss their implications for contemporary psychiatric practice. This review may help to standardize the introduction of legislation that allows involuntary admission and treatment of patients with mental disorders in the mainland of China, and contribute to improved mental-health care. In this review, involuntary admission or treatment does not include the placement of mentally-ill offenders, or any other aspect of forensic psychiatry.
